Heat treatment products are loaded into the furnace

Heat treatment products are loaded into the furnace

1) The charging amount of each furnace shall not exceed the maximum charging amount specified for the electric furnace. The dimensions of all workpieces shall be compatible with the dimensions of the electric furnace working room.

2) The furnace loading position of workpiece shall be within the heating area of electric furnace. Keep a certain distance from the furnace top, furnace wall and resistance wire. A sizing block shall be added at the bottom, and the parts shall be separated by 30mm to ensure the circulation of hot air flow.

3) The furnace loading position of workpieces shall be based on the analysis of furnace allocation. Workpieces of various brands and sizes shall adapt to the operation sequence considered and can be discharged.

4) During furnace loading, the bottom cushion block shall be leveled, and the workpieces shall be evenly stacked on the trolley, reasonably stacked from bottom to top, leveled and firmly padded, so as to avoid uneven charging in the furnace, resulting in temperature difference in each area, and prevent rollover, stacking and impact on the furnace wall when the trolley moves.

5) For ultra-thin and ultra long workpieces, when assembling the furnace, their stacking position in the furnace shall be considered, and process measures shall be taken to prevent deformation during heating and hoisting.

6) For the finished workpiece, the workpiece surface and edges and corners shall be protected during furnace loading to prevent oxidative decarburization and bruise. The parts of the workpiece prone to cracking (cavity, sharp corner, thread, slot hole, etc.) shall be protected with thermal insulation materials.

7) After the trolley enters the furnace, if there is a large heat dissipation gap caused by furnace body damage, it shall be blocked.
