The Yiran quenching and tempering furnace can perform quenching and tempering heat treatment on workpieces, including heating, warming up, insulation, quenching cooling, and tempering. The complete production line adopts PLC control and touch screen display for easy operation, with advantages such as online continuous heating and high degree of automation. The mining and engineering machinery heat treatment and tempering production lines, as well as the Yiran heat treatment and tempering production line, use three roll straightening and natural gas regenerative combustion heating for quenching. The workpiece running speed, heating temperature, and heating efficiency are centrally controlled by PLC, forming a closed-loop control system to achieve functions such as recording, archiving, querying, and printing of all production data.

The quenching and tempering furnace mainly consists of a thermal storage combustion system, a flue gas recovery system, an automatic feeding device, a pressure roller rapid discharge device, an infrared temperature measurement device, and a control console. By matching different sensors, it is possible to achieve heating, heating temperature, radial and axial temperature difference process requirements for anchor chain steel, as well as insulation materials, and automatically record the temperature of each bar material.

The main purpose of the Yiran quenching and tempering furnace is for melting, casting, forging, and heat treatment. It has a large capacity and can heat the entire workpiece. The advantages of quenching machine tools are quenching, single piece processing, and partial quenching of workpieces. The quenching and tempering furnace produced by Yiran utilizes sensors and PLC intelligent control of quenching temperature, and is widely used in shipbuilding, automotive, chemical, power, construction, machinery, petroleum, and bridge industries.
