Application of Alloyed Cast Iron to Increase the Durability of Products of the Mining and Metallurgical Industry

The article shows the relevance of the use of alloyed cast iron in mining and metallurgical engineering. The use of cast iron alloyed with titanium and vanadium has not been sufficiently studied for the working bodies and friction units of mining machines, such as pumps, coal scoops, hydrocyclones, crushers and mills. They have the main abrasive type of wear. This work considers the influence of titanium and vanadium on the mechanical properties. The performance indicators of parts of mining machines and metallurgical products in contact with high-abrasive and high-temperature environments is also considered. The optimal content of titanium and vanadium in gray cast iron in the range of 0.05-0.1% is set. This provides the required strength properties of the components, while increasing their heat resistance. Bushings made of this cast iron have the required wear resistance and can improve the operational reliability of equipment in mining and metallurgical industries.
