1.Vertical resistance heating design, cylindrical hot zone, mainly for gas quenching, tempering, annealing treatment;
2.The rated heating temperature is 1300 ° C, the rated gas cooling pressure is 3 bars (abs), the cooling gas is nitrogen;
3.The heating and insulation layer are graphite made, and the heaters are installed and fixed on the insulation layer;
4.The cooling gas is ejected from the nozzle with 360 ° distribution around the heating chamber to realize the uniform cooling of the heat-treated products in the heating chamber;
5.The supporting material platform is designed on the furnace door at the bottom. The rotating design can drive the product to rotate while cooling, and effectively control the deformation.
6. The furnace door adopts the up-down lifting design, and moves horizontally on the guide rail after falling to the ground height, so as to facilitate the loading of products.
