Chain conveying equipment uses chains as the main load-bearing body. Due to the large allowable length error of the chains, the wear of the chains during use can also cause the pitch of the chains to elongate. Therefore, the chain conveyor equipment must be designed with a tensioning device. The ... Read More

The heat treatment process of heating a metal or alloy to an appropriate temperature, holding it for a certain period of time, and then slowly cooling it (usually with furnace cooling) is called annealing. The essence of annealing is to heat steel to austenitize and undergo pearlite transformation, ... Read More
