The cooling water tank leaks. If water leaks, the surface color of the quenched product will be blue-gray, and there will be peeling on the surface in severe cases. The reason is that the cooling water tank of the mesh belt under the quenching furnace leaks water into the inner cavity of the mesh belt, and the water is gasified and then goes upward. Push it into the furnace hall to oxidize and decarburize the surface of the product. The remedy is to find the leak point and weld it firmly, or replace the cooling tank with a new one.Vacuum Hardening Furnace From the surface color of the air leakage and decarburization products, it is slightly whiter than the normal color, unnatural, and has serious peeling phenomenon. Find the air leakage point: Furnace muffle cavity - the interface of the blanking dragon mouth - the cooling tank - the liquid level of the quenching medium, etc.X6230 SERIES UNIVERSAL SWIVEL HEAD MILLING MACHINE The liquid level of the quenching medium is low, and the air leakage is low, and the quenching medium should be replenished (special attention should be paid here that it may cause a fire). The muffle cavity is viewed from the furnace door first, and there is a dark area first where the air leaks.X5746 X5750 X5750A UNIVERSAL RAM MILLING MACHINE That is, the air leakage area is darker than other areas, and if the air leakage is serious, there will be flames ejected into the furnace cavity. If the visible place is normal, it is necessary to consider other places.Heat treatment process of gear vacuum carburizing and quenching
