Silicon carbide rod with 8/14 diameter at the thick end
$20
Category: Chemicals/Oxides/Other Oxides
Company: Dengfeng Minghui High-Temperature Elements Co., Ltd.
Product Description: Thick-end silicon carbide rods, also known as large-head rods or non-uniform diameter silicon carbide rods. Our company is a manufacturer of silicon carbide rods, specializing in custom-made thick-end silicon carbide rods. Some specifications of 8/14 are available in stock. Welcome to inquire.Silicon carbide rods are non-linear resistors. At room temperature, the resistance varies significantly. When heated, the resistance gradually decreases from room temperature to 850°C ± 50°C, slowly increases between 800°C and 900°C, and stabilizes around 1050°C ± 50°C. The resistance measured at this stage is relatively standard, making it easier to pair appropriately during installation. In terms of shape, there are thick-end silicon carbide rods, uniform diameter type, U-type, right-angle, gate-type, H-type, h-type, threaded type, five-section type, groove type, etc.When silicon carbide rods are used for extended periods at high temperatures, the surface of SiC oxidizes, gradually increasing the SiO2 content in the element, which leads to an increase in resistance. This is a normal phenomenon known as "aging." During the first 500 hours of use, the aging process is rapid, after which it slows down, primarily because the SiO2 film on the surface of the element slows down the oxidation of SiC. The aging rate of silicon carbide rods depends on the operating temperature and surface load density. To maintain constant power and achieve the desired furnace temperature, it is necessary to use a corresponding voltage regulator to accommodate the increasing resistance of the element during use. more>

U-shaped silicon carbide heating tube with silicon carbon rod material
$71
Category: Chemicals/Inorganic Salts/Silicates
Company: Dengfeng Minghui High-Temperature Elements Co., Ltd.
Product Description:  Silicon carbide is divided into black silicon carbide and green silicon carbide, with the latter having higher purity and commonly used in the abrasive industry and electrical engineering. The production of silicon carbide heating elements, such as silicon carbon rods, utilizes the properties of silicon carbide being conductive, thermally conductive, stable in nature, and having a long service life. Silicon carbon rods do not react with any acids. However, at around 1300 degrees Celsius, they can undergo chemical reactions with alkalis and alkaline oxides. Silicon carbon rods have a certain degree of oxidation resistance. When the rod temperature reaches 800 degrees Celsius, an oxidation reaction begins on the surface. As the temperature continues to rise, the silicon carbon rod forms a protective layer of SiO2 with the air, which prevents further oxidation of the rod and extends its service life. The protective layer of silicon dioxide has a specific melting point; when the rod temperature exceeds 1600°C, the protective layer may be damaged or peel off, causing the silicon carbon rod to continue oxidizing. Continued use will regenerate the protective film. Therefore, it is recommended to use silicon carbon rod elements continuously and avoid excessively high rod temperatures. Proper design of the electric furnace and silicon carbon rod parameters, along with correct usage, are key to maximizing the lifespan of silicon carbon rods. The typical furnace temperature for silicon carbon rod heating elements is between 1000°C and 1350°C. Hollow silicon carbon rods are more commonly used because they do not require specific molds, have low production costs, and are simple and convenient to manufacture, with a wide range of available lengths and diameters. Solid silicon carbon rods, on the other hand, are limited by mold constraints and have fewer specifications, but they offer a longer service life. They also have advantages in terms of heating speed and temperature resistance. U-shaped silicon carbon rods are commonly used in production. They feature single-end wiring for convenient use and are often applied in experimental furnaces, roasting furnaces, Jianzhan kilns, metal melting furnaces, glass melting furnaces, crucible furnaces, and other types of kilns. They come in various diameters and lengths. Dengfeng Minghui High-Temperature Components Co., Ltd. offers custom-made products with stable quality and uniform heating. Each rod undergoes strict testing and is certified before leaving the factory. For custom silicon carbon rods, please feel free to call us. We will calculate based on parameters and provide a reasonable quotation. more>

Product Description: The 2-meter micro tubular feeding screw conveyor excels in powder material transportation quality, Application Scope and Features:(1) Hebei screw conveyor is a widely used conveying equipment in chemical, building materials, grain, and other sectors, mainly for transporting powdered, granular, and small lump materials. It is not suitable for conveying perishable, sticky, and easily agglomerated materials. (2) The operating environmental temperature for screw conveyors is —20~50℃ ; the conveyor's inclination angle β≤20°; the conveying length is generally less than 40m, with a maximum not exceeding 70m. (3) Compared to other conveying equipment, screw conveyors have advantages such as simple structure, small cross-sectional dimensions, good sealing performance, the ability to load and unload at multiple points along the length, safe and convenient operation, and low manufacturing costs. Their disadvantages include severe wear on components, lower conveying capacity, high power consumption, and the tendency for materials to break during transportation.Classification and Structural Features:(1) The screw blades of screw conveyors come in three types: solid spiral surface type, belt spiral surface type, and blade spiral surface type. The solid spiral surface is called the S method, with its screw pitch being 0.8 times the blade diameter for the GX type, and the LS type screw conveyor is suitable for conveying powdered and granular materials. The belt spiral surface, also known as the D method, has a screw pitch equal to the screw blade diameter and is suitable for conveying powdered and small lump materials. The blade spiral surface is less commonly used, mainly for conveying highly viscous and compressible materials, and it can simultaneously complete processes like mixing and blending during transportation, with a screw pitch approximately 1.2 times the blade diameter. (2) The screw blades of screw conveyors come in two rotational directions: left-hand and right-hand.The 2-meter micro tubular feeding screw conveyor excels in powder material transportation quality. more>
