Without oxidation heating rotary kiln, the use of incomplete combustion of fuel gas recovery, in which the heating workpiece can make oxidation burning loss rate reduce to below 0.3%. Visibly anaerobic heating is good rotary kiln.

In order to obtain standard precise and smooth surface of the workpiece, perhaps in order to reduce the metal oxide to reach protect mould, or reduce machining allowance, etc.,  you can choose a variety of non-oxidation heating rotary kiln.

Non- oxidation heating can ensure smoothness of rotary kiln. Within the casting heat rotary kiln, enhancing metal heating temperature, can reduce the resistance to deformation, but the temperature is too high and will cause the grain growth, oxidation or burnt, seriously affect the workpiece quality. Industrial planning, heating process, the temperature control of rotary kiln and kiln atmosphere, etc., directly affects the quality of the products after processing.

In the process of heat treatment, if the steel is heated to above the critical temperature point, and then suddenly cooling,it can enhance the steel hardness and strength. If heated to a temperature below the critical temperature to a certain point after slow cooling, and it can reduce the hardness of steel and make the flexibility to move forward.
