Background

Heat treatment refers to a hot metal working process in which a material is heated, held and cooled in the solid state to achieve a desired texture and properties. In the process of moving from the times of stoneware to the times of cupreous and ironware, the effect of heat treatment is gradually recognized. The heat treatment process generally comprises three processes of heating, heat preservation and cooling, and sometimes only comprises two processes of heating and cooling. These processes are connected with each other without interruption. Heating is one of the important steps of heat treatment.

When a box-type resistance furnace is adopted in a heat treatment workshop at present to carry out a workpiece heat treatment process, the work mode that a workpiece is manually sent into and taken out of a heating electric furnace by using an iron tool is adopted, and because the heating temperature of the electric furnace is very high, an operator not only needs to be burnt by high temperature when sending the workpiece, but also is slightly carelessly and extremely easy to cause the danger of personnel burn or fire during operation; moreover, some workpieces are heavy, which causes great labor intensity and hard work of operators.
