Mechanical part inspection: check and adjust the alignment of the mesh belt; check the liquid level of the quenching tank and blackening tank; check each transmission system, electrical part inspection: check the wiring between the control cabinet and the furnace body;Aluminum alloy vacuum brazing 0000 check the insulation of the heating element Check the fastening of the wiring; adjust the temperature control instruments and check the safety devices of the equipment. Deformation and Improvement of Vacuum Sintered Cemented Carbide After the furnace temperature drops to 700°C~750°C, adjust the exhaust pipe switch to fully open and open the debris removal port in the furnace to allow fresh air to enter the furnace to help burn carbon deposits. The coal burning time is about 4 hours to 8 hours; When the temperature in the furnace rises to 900°C, close the debris removal port to reduce the air flow, and protect the parts in the furnace from being damaged due to overheating (note that the furnace temperature must not exceed 900°C); Application of Vacuum Heat Treatment in Fastener Manufacturing when the temperature drops below 400°C , You can open the impurity removal port to clean up the debris and carbon deposits in the furnace. Pay attention to the sound and operation of electrical appliances and mechanical transmission at any time. If there is any abnormality, stop the machine immediately and work after troubleshooting. Drive the crane to a fixed position, return the button or handle to the zero position, and turn off the power.Optimal Vacuum Heat Treatment For Bevel Gears
