Heat treatment resistance furnace heat treatment tooling is also a large one, its composition is not complicated, mainly several key parts hob, furnace shell, lining, mouth devices. Since each part of the function is different, and therefore should be distinguished from the requirements of the design.

First comes the heat treatment resistance furnace grate and the furnace shell, which is used to bear the load hob furnace arch support and lateral thrust lining and the workpiece, and thus into a welded steel frame and steel in its outer package, in order to obtain sufficient strength. The role is to protect the furnace shell lining, reinforcement and maintenance of electric furnace structure tightness, so the use of complex steel plate attached to the steel frame design.
Come talk about the lining, in order to use it to keep the furnace temperature, reducing heat loss, lining materials have a certain strength, refractoriness, resistance to thermal shock resistance and less heat build. Materials that meet these criteria have light refractory bricks and refractory fiber, so they are also the most widely used.
