This series of spider annealing furnaces is a new type, energy-saving and environmentally friendly heat treatment equipment advocated by the state. It has a super energy-saving structure and is mainly used for the annealing of metal products such as rotor brackets, stator brackets, forging par......
Read MoreThe snow chain is a kind of annular chain installed on the tire of the car. It is mainly used for anti-skid driving in snowy weather to ensure safe driving. It is an essential tool for driving in the alpine zone in winter. Therefore, the snow chain is required to be wear-resistant and not brok......
Read MoreAmong various heat treatment processes, the annealing process is one of the most common. So, what exactly is an annealing process? What are the specific types of annealing processes, let us analyze them one by one: 1. Annealing concept Annealing is a heat treatment process in which metals and ......
Read MoreA. Large block or network carbides appear in the carburized layer The cause of the defect: the surface carbon concentration is too high 1. Drip carburizing, the drop volume is too large 2. Controlled atmosphere carburizing, too much enriched gas 3. Liquid carburizing, excessive cyanide content......
Read MoreThis paper discusses various factors that affect the quenching deformation in the process of carburizing and quenching. Mainly include charging method, blank quality, quenching oil selection, carburizing temperature, quenching temperature and heating rate. Through the discussion of the influen......
Read MoreCarburizing and nitriding are two common heat treatment processes, but these two processes are also prone to some problems in operation: 1.How to prevent carburization where the workpiece is machined? (1) Copper plating method, plating a copper layer with a thickness of more than 20mm (2) Afte......
Read More1. Reasons for deformation The main reason for the deformation of steel is the existence of internal stress or externally applied stress in the steel. Internal stress is caused by uneven temperature distribution or phase transformation, and residual stress is also one of the reasons. The defor......
