Welding platform

The Beizhong Riveting and Welding Platform is one of the flagship products of Beizhong Company, capable of withstanding high-temperature forging, and is now widely used in the riveting and welding processes of workpieces. The material of the riveting and welding platform is HT200-300.
Types of Riveting and Welding Platforms: To meet the diverse needs of industrial production, the materials are further categorized into gray iron HT200-300 riveting and welding platforms, nodular cast iron QT400-600 riveting and welding platforms, cast steel ZG15-45 riveting and welding platforms, etc.
Manufacturing Standards of Riveting and Welding Platforms: Produced according to the latest national standard GB/T22095-2008. Structural Standards of Riveting and Welding Platforms: The thickness of the working surface, the thickness and height of the sidewalls, as well as the thickness, height, and density of the bottom rib plates must be structurally reasonable. It serves as an auxiliary tool in the riveting and welding process, providing a reference positioning surface for various riveting and welding tasks.
Chemical Composition of Riveting and Welding Platforms: Carbon content is between 3.16% and 3.30%, making it an iron-carbon alloy. Carbon in the riveting and welding platform mostly exists in the form of graphite, and sometimes as cementite. In addition to carbon, the riveting and welding platform also contains silicon (Si: 1.79-1.93), manganese (Mn: 0.89-1.04), sulfur (S: 0.094-0.125), phosphorus (P: 0.120-0.170), as well as elements such as nickel (Ni), chromium (Cr), molybdenum (Mo), aluminum, copper, boron (B), vanadium (V), etc. Carbon and silicon are the main elements affecting the microstructure and properties of cast iron. The fracture surface of the riveting and welding platform is gray, with a low melting point (1145-1250°C), minimal shrinkage during solidification, compressive strength close to that of carbon steel, and excellent vibration damping, heat resistance, and wear resistance.
Production Process of Riveting and Welding Platforms: 1. Develop a production plan and design drawings;
2. Create the lost foam - foam mold;
3. Sand pit molding;
4. Pouring;
5. Annealing the rough castings;
6. Rough machining on the machine tool;
7. Perform secondary annealing to relieve internal stress and prevent deformation;
8. Precision machining on the machine tool to achieve the final platform dimensions;
9. Manual scraping for platforms requiring high flatness;
10. Finish the platform's appearance and package it.
Specifications and Accuracy of Riveting and Welding Platforms: Specifications range from 1000*1200 mm to 3000*8000 mm, with dozens of options available. Custom specifications can be manufactured based on user requirements and provided drawings. Accuracy: Follows national standard metrological verification regulations, with four grades: 0, 1, 2, and 3.
