AI Technical Summary
Technical Problem
The existing graphite flap door has poor sealing performance, which leads to heat loss in the furnace, increases energy consumption, and affects the heat treatment effect of the product.
Method used
The automatic opening and closing graphite flip door structure includes an outer frame, an inner flip panel, and an automatic flip hinge. It utilizes a torsion spring and the gravity of the inner flip panel to achieve automatic closing. The combination of high-temperature resistant stainless steel and isostatic graphite materials improves sealing and durability.
Benefits of technology
It achieves a good sealing effect, prevents heat loss from the furnace, reduces energy consumption, ensures the heat treatment effect of the product, and extends the service life of the equipment.
