Product Description: Due to fluctuations in raw material prices, the pricing and models may vary. For specific quotations, please contact our sales representatives. Thank you.If the underground support is slightly twisted, try replacing it with a matching nylon column cap—its grooves can secure the pillar, and its thick disc surface allows for fine adjustments according to the roof angle, gradually "straightening" the twisted force and realigning the pillar. This small component may seem simple, but at critical moments, it can pull off-track support back on course, creating a safe space～Mine-used column shoes and caps are primarily used for support in coal mines and other mining tunnels or工作面. They enhance support stability through the initial support force and roof-thrust force of individual pillars, preventing roof accidents.Specific Uses:Enhancing Support Stability: By utilizing the initial support force (the pillar's initial bearing capacity) and roof-thrust force (the pillar's pushing force against the roof), they effectively control roof subsidence and ensure operational safety.Adapting to Complex Geological Conditions: Suitable for scenarios requiring temporary support, such as coal mining faces and tunnels, particularly in areas with high roof pressure or complex geological conditions.Materials and Craftsmanship: Common materials include cast iron and nylon. Nylon offers anti-static properties and lightweight characteristics, meeting the requirements for equipment lightweighting and safety in underground operations.Specifications and Compatibility:Common diameters include 260mm, 280mm, 300mm, 320mm, and 350mm. Custom non-standard specifications can also be produced based on actual needs.These seemingly simple design details—every curve and every interface—ensure that the column shoes fit perfectly in the complex environment of mines, with dimensions meticulously matched for optimal performance. more>

Product Description: DG60DG60 non-magnetic steel, also known as DG60 non-magnetic hard alloy steel, is a type of high-hardness non-magnetic mold steel. This steel can be directly quenched after carburization, offering advantages such as high production efficiency, low cost, and minimal oxidation and decarburization. However, due to its high hardness, it has relatively poor toughness. The as-delivered hardness of DG60 is 55-60 HRC.DG60 non-magnetic steel has a high hardness of HRC 57-61.Q: What material is DG60? Performance introduction.A: DG60 non-magnetic steel. This steel maintains a stable austenitic structure under various conditions, with very low magnetic permeability, high hardness and strength, and relatively good wear resistance.Q: What is the difference between DG60 and imported HPM75?A: HPM75 and DG60 differ in hardness;Q: What is the as-delivered HRC hardness of DG60?A: As-delivered hardness is HRC 57-61;Q: What is the chemical composition of DG60?A: Reference: Ni 55, Cr 45, with the remainder being rare earth elements. Tested hardness ranges from 57 to 61, grain size is grade 5, bending strength is 716 kg, impact toughness is 1.05 KG-M, and magnetic permeability is 1.0001.Q: What is DG60 non-magnetic steel used for?A: DG60 is suitable for manufacturing non-magnetic molds, non-magnetic bearings, and other structural components that require no magnetic induction in strong magnetic fields.Q: Is DG60 the same as stainless steel 304?A: DG60 is a non-magnetic mold material, while 304 is a genuine stainless steel series;Q: What is the price of DG60?A: DG60 non-magnetic steel is divided into two types: raw material and processed material (after solution treatment). Some unscrupulous manufacturers use stainless steel as a substitute, leading many companies to purchase materials in two batches, increasing original costs.Q: What is the heat treatment method for DG60 non-magnetic steel?A: DG60 has already undergone hardness treatment upon delivery.DG60 is a high-hardness non-magnetic mold steel, also known as non-magnetic hard alloy steel; its as-delivered hardness is HRC 58-62. DG60 non-magnetic hard alloy and non-magnetic steel (7Mn15Cr2Al3V2WMo, hereinafter referred to as 7Mn15Cr2Al3V2WMo). Non-magnetic hard alloy offers good wear resistance but has a long production cycle and high mold processing costs, making it suitable for long-term products. 7Mn15 non-magnetic steel has lower wear resistance, a shorter mold manufacturing cycle, and lower costs, making it suitable for products with limited production volumes and short cycle requirements. The application range of DG60 non-magnetic steel is relatively narrow, and its heat treatment and processing工艺流程 as a mold are not widely understood.DG60 (1) Direct Quenching: Direct quenching after carburization offers high production efficiency, low cost, and minimal oxidation and decarburization. However, due to the high carburization temperature, austenite grains grow, resulting in coarse martensite and more retained austenite after quenching, leading to poorer wear resistance and toughness. It is only suitable for fine-grained steels and parts with low wear resistance or low load-bearing requirements.DG60 (2) Single Quenching: After slow cooling from carburization, the steel is reheated above the critical temperature, held, and then quenched. Compared to direct quenching, single quenching can refine the steel's structure to some extent. When high core structure requirements exist, the single quenching temperature is slightly above Ac3. For parts requiring high surface wear resistance and hardness but low load-bearing, the quenching temperature should be 30°C–50°C above Ac1 to refine surface grains while leaving the core structure largely unchanged, resulting in slightly lower performance.DG60 (3) Double Quenching: For parts requiring high mechanical properties or coarse-grained steels, double quenching should be used. The first quenching aims to improve the core structure, with a heating temperature 30°C–50°C above Ac3. The second quenching aims to refine the surface structure, obtaining fine martensite and uniformly distributed granular secondary carbides, with a heating temperature 30°C–50°C above Ac1. DG60 is a high-hardness non-magnetic mold steel, also known as non-magnetic hard alloy steel; its as-delivered hardness is HRC 58-62. Austenitic non-magnetic steels are divided into non-magnetic high-manganese structural steels and non-magnetic stainless steels. Non-magnetic high-manganese structural steels are mainly used in civil fields such as power, transportation, and construction, while non-magnetic stainless steels are primarily used in high-tech fields like national defense and military industries. This analysis covers the domestic and international development and research overview of Fe-Mn series, Fe-Mn-Cr series, and Fe-Mn-Al series non-magnetic high-manganese structural steels, as well as non-magnetic stainless steels. It proposes China's development strategy for creating reduced-resource high-manganese non-magnetic steels that save on metals like Ni, Mo, and Cr, and high-end non-magnetic stainless steels. This approach meets both the mechanical and non-magnetic performance needs of civil applications and the comprehensive performance requirements of national defense and military applications, such as good mechanical properties, weldability, and corrosion resistance.Zexin Metal DG60 Non-Magnetic Steel Grade, Metallographic Structure, Mechanical Properties, Compressive Strength, Yield Strength, Elongation, Reduction of Area, Aging Temperature, Solution Treatment Strength, Processing Tools, Heat Treatment, Chemical Composition, Standard Specific Gravity, Hardness, Density, Non-Magnetic Steel Processing Tools, Non-Magnetic Steel Drilling, Tapping, and other mold steel information, please consult Dongguan Zexin Metal Materials. more>

Product Description: Side Rubber Sealing Coal Belt for Material Leakage Under Conveyor ChuteSide rubber conveyor, side rubber chute, side rubberSide rubber is a rubber plate used for sealing between the conveyor belt and the chute, as well as between the buffer bed and the chute. Its design and material selection are crucial to ensure it can withstand long-term friction and effectively prevent material spillage and dust reduction.Here are some detailed information about side rubber:Installation MethodsThere are two main installation methods for side rubber: butterfly nut type and handle type. The installation process involves directly mounting the side rubber under the edge of the conveyor chute, ensuring accurate positioning to guarantee its sealing effect.Material SelectionThe part of the side rubber that contacts the belt is usually made of polyurethane blocks due to their high wear resistance. The polyurethane blocks and rubber plate are bonded using a hot vulcanization process, enabling them to endure prolonged friction without separating. Additionally, the rubber of the anti-spill skirt is synthetic rubber, which requires blending with heat-resistant, aging-resistant, and damage-resistant additives such as styrene-butadiene rubber to ensure performance.Usage Characteristics of Side RubberSide rubber is convenient and quick to use, featuring a double-layer seal: the inner layer prevents material spillage, while the outer layer reduces dust. The area in contact with the belt has a composite polyurethane layer, which ensures a long service life without damaging the belt. These characteristics enable side rubber to fundamentally solve issues such as coal spillage, air leakage, and powder escape on both sides of the chute, effectively reducing dust concentration in the belt corridor.PrecautionsWhen selecting side rubber, users should be aware that there are low-quality anti-spill skirts on the market, which may be made from reprocessed waste rubber products. Such anti-spill skirts might melt at slightly elevated temperatures, leading to premature belt failure. Therefore, users should purchase side rubber from reputable manufacturers, request samples for testing, and confirm that the hardness is appropriate and there is no strong odor before making a purchase.The above is some key information about side rubber. I hope it is helpful to you. If you need more detailed information or have specific questions, feel free to consult me at any time. more>
