1) preparation of stainless steel tube, the operator must first be familiar with parts diagram, control the physical understanding of stainless steel castings technical requirements, determine the process parameters as stainless steel casting process, familiar with the physical size, select the appropriate fixtures and stainless steel furnace specifications size . You can check the material, grinding sparks, playing spectroscopy or chemical composition analysis, if the error is found immediately stop production and inspection of parts exterior cracks, with or without deep knife marks, if oil should be cleaned.

2) the workpiece into the furnace heating, everything is ready to start the furnace temperature, furnace temperature rose to 600-650 ℃ after fan can start while opening the cooling water cooling. Workpiece as the door closed after the furnace lid or cover, turn the fan power, adjust the meter pointer to a certain temperature, when the furnace temperature difference is corrected for instrument error indication to be approved.

3) casting quality control, the primary control surface hardness, surface structure, concentration, hardness, and specific industries can be found in the technical requirements for steel castings.
