Product introduction:
    This lithium battery cathode material sintering equipment is a bottom-loading box-type atmosphere furnace with a maximum temperature of 1400°C. The furnace material of this equipment is high-purity alumina fiber, and silicon carbide rod is used as the heating element (4 sides heating, more uniform temperature field). The furnace body can be evacuated & can pass into the atmosphere, and the material can be heat treated in an inert atmosphere and an O2 atmosphere. The hydraulic lifting platform + freely movable material cart (with positioning and limit) is very convenient for material in and out operations.
