What is a sealing cap The sealing cover (furnace cover) of the electric heating reverberatory furnace only bears the pressure of the gas, and the structure is relatively simple.Vacuum carburizing process of auto parts However, the No. 7 part in the sealing cover of the resistance heating furnace has poor working conditions and strict requirements. It needs to be sealed with the crucible; at the same time, it must be sealed with the riser; during pressure maintenance and pouring, it needs to be sealed with the casting mold. Tightly fit and withstand the impact of the weight of the mold and the opening and closing mechanism. Shaft machining vacuum heat treatmentTherefore, the sealing cover must meet the following requirements: first, it is not easy to deform under the action of external force and heat, and the sealing performance is good; second, the temperature of the joint part with the riser pipe is easy to control; third, it is easy to assemble and fasten. The sealing cover material is generally cast with ductile iron or gray iron, and should not be made of steel.Vacuum carburizing process of auto parts

How does the heating furnace work? Stove the furnace:Advantages of vacuum sintering of cemented carbide (1) Check the water level of the heating furnace. The liquid level gauge shows that the liquid level is between 40 and 70 (1/2 to 2/3 of the heating furnace). If the water level is lacking, fill the furnace with water and flush the level gauge at the same time.Differential ring gear vacuum heat treatment (2) Check the pressure regulating valve to ensure that the pressure of the gas supply line is within a suitable range (about 1 kPa).Vacuum annealing process of automobile half shaft 3) Turn on the power switch of the temperature control box and press the burner start button.Vacuum Heat Treatment and Nitrocarburizing of Hot Work Die Steel 4Cr5MoSiV1

1. If the water jacket leaks or the stirring rod leaks, and the stirring water seal leaks, it should not be converted to a hot standby furnace. If the valve of the air branch pipe is not tightly closed or the saturated steam valve is seriously leaked and cannot be repaired and replaced during the hot standby, it should not be used as a hot standby.Vacuum Brazing Technology of Static Guide Vane Ring 2. When planning hot standby, a producer with better furnace condition should be selected for hot standby. If the fire layer is selected to fall, serious slagging will occur in the furnace to generate hot standby, which will inevitably worsen the furnace condition. 3. For the production furnace planned for hot standby, the furnace should be probed in advance, and the part with a small amount of slag should be drilled to break the slag, and drilled at each point of the furnace section to make the furnace section basically tight. 4. Appropriately reduce the ash layer. 5. Properly thicken the coal seam.C/C composite brake material 6. Check whether the maximum relief valve cover is flexible. 7. First reduce the air volume before hot backup. 8. Seal the double vertical pipe water seal, and pull up the maximum release valve in time according to the furnace pressure.Wave spring vacuum heat treatment
