Metal pit type electric heating vacuum annealing furnace
In this type of furnace, medium ainly is used for metal parts that are heat-treated in natural or protective atmospheres.
Suitable for bright tempering of a NEA - ing carbon steel, alloy steel and magnetic materials in a protective atmosphere, and bright annealing for small batch rolling bars
1) shell: made of steel plate and structural steel.
2) inside the furnace cover: made of stainless steel plate.
3) burner lining: ultra-light energy-saving micro-hole refractory insulation brick is used
4) there are aluminum silicate fibers between the burner lining and the housing, and the gap is filled with insulation.
5) resistance wire: use 0Cr25Al5 high resistance alloy wire mounted on the brick.
6) furnace cover: use manual lever lifter or electric or hydraulic drive.
7), we installed a fan made of heat-resistant stainless steel shaft and fan blade to evenly heat the workpiece
8). A limit switch is installed near the lifting device to ensure safe operation.
