Refrigeration parts oxygen annealing furnace
 

    Refrigeration parts oxygen annealing furnace is designed such as brass, copper valve for refrigeration fittings industry: three, four, two, valve body, side valve, ball valve, check valve, pipe nut, stem, and other special production pipe furnace type development.

    

For refrigeration accessories enterprises, the preferred type of furnace for oxygen box annealing furnace, the furnace advantages, heating speed, temperature uniformity, large daily output, simple and convenient operation, workers will teach, technical difficulty is low. By the vast numbers of users, especially the refrigeration accessories industry.

    

The structure of an oxygen annealing furnace is mainly composed of a furnace body, a furnace lining, a furnace bottom plate, a heating element, a hot air circulation system, a furnace door and a control system. The furnace frame is made of channel steel and angle iron, and the whole strength is good, and it is difficult to deform. The lining is a compound structure with good airtightness. The utility model has the advantages of firmness, reliability, convenient maintenance, long service life, good energy saving effect, small temperature rise of the shell of the furnace body, etc.. Heat resistant steel furnace bottom plate for the use of the workpiece, reducing deformation and cracking at high temperature. The heating element distributes the power according to the uniformity of the furnace temperature, the heating elements are arranged on the left and the right side walls and the bottom of the furnace, and the heating element is made of an alloy resistor belt to form a corrugated type. The heating element on the bottom of the furnace is tiled in the groove of the refractory brick, and is fixed by the shape, the surface load of the utility model is smaller than that of the heating element in other parts, and the replacement and the maintenance are convenient.

    

The oxygen annealing furnace has a wide temperature range, low equipment cost and many kinds of process, and can be used for the quenching, tempering, annealing, solid solution, aging and stress removing heat treatment processes of copper tubes and copper valves. The process is simple, the heating speed is fast, the temperature is even, the daily output is large, the operation is simple and convenient, and the workers will be taught, and the technical difficulty is low. As the refrigeration accessories follow-up process has polishing, cleaning and other processes, just make up the copper pipe oxidation black problem, especially suitable for refrigeration parts industry copper tube, copper valve heat treatment.
