Oil bath tempering furnace

　　Oil bath tempering furnace is a type of oil bath furnace,mainly used for low-temperature tempering of high hardness parts such as cutting tools,measuring tools,molds,nitriding,carburizing,etc. made of carbon tool steel and low-alloy tool steel.

Oil bath tempering furnace

　　This oil bath reheating furnace is equipped with a heating system,stirring system,safety system,automatic control system,and other components.

　　The oil bath tempering furnace body is welded and processed from thickened steel plates and section steel,using section steel as the frame. The exterior has a furnace shell welded with steel plates,and the interior is an oil tank liner bent and welded from thickened stainless steel. The middle is filled with refractory fibers to form a thermal insulation layer. The furnace cover can adopt a movable structure. The heating module is composed of stainless steel heating tubes. One side of the oil tank is equipped with an insulated stirring system,which ensures uniform temperature and flow of the medium in the effective quenching zone. The workpiece has a wide heating surface and uniform tempering. Especially for small and micro precision bearing rings,the quenching stress relief is sufficient,the dimensional stability is good,the hardness is uniform,and it will not cause distortion of the finished product due to insufficient tempering after assembly.

　　The heating control system of Chengchi brand oil bath reheating furnace adopts microcomputer PID control SRR solid state relay. Solid state relay is a switch element without mechanical contacts,which has the advantages of flexible control,high reliability,long service life,no electric sparks generated during on and off time,no noise,fast switching speed,high working frequency,and strong anti-interference ability. In addition,the oil bath tempering furnace is equipped with various sensors to better utilize the potential of the equipment. Various adaptive functions can also be customized according to user production needs to meet production demands.

　　Safe use of oil bath furnace return furnace: The control system is equipped with one in use and one backup,with two temperature monitoring and control systems. Even if one control system is abnormal or faulty,when the temperature rises to the set temperature in any one of the systems,the heating will be immediately disconnected and an audible and visual alarm will be issued. There is a set of fire extinguishing pipelines arranged along the oil groove of this furnace,and users can equip carbon dioxide/nitrogen cylinders. Even in the event of a fire,the fire extinguishing system can be turned on to spray carbon dioxide/nitrogen into the oil groove. Due to the high density of nitrogen/carbon dioxide,it floats on the oil surface and can achieve sufficient fire extinguishing effect. (Usually,it can be done by closing the furnace cover or covering it with a fire blanket,and it can be reused.)
