Heat resistant steel casting chain links, as an important component of furnace bottom rollers, undertake critical industrial applications. The chain link is made of heat-resistant steel casting, and its main characteristics include wear resistance and corrosion resistance at high temperatures. As an important component of industrial furnaces, the furnace bottom roller is connected by chain links to support and transfer materials inside the furnace, ensuring the continuous and smooth production process. The design and manufacturing of heat-resistant steel casting chain links take into account thermal expansion and material friction at high temperatures, ensuring their reliable operation even under harsh working conditions. Heat resistant steel casting chain links are widely used in furnace bottom systems in industries such as metallurgy and chemical engineering.
