The magnesium alloy quantitative furnace adopts a flat belt type resistance heating method, with extremely high thermal conductivity, uniform temperature, energy conservation and environmental protection. It uses double pumps for quantitative analysis, precise quantitative analysis, and maintains the constant clamping pressure of the die-casting machine. It is automatically quantified through an automatic quantitative system and a feeding pipe for die-casting, and is widely used in supporting furnaces for die-casting equipment.
