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. 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. 6. Check whether the maximum relief valve cover is flexible. 7. First reduce the air volume before hot backup.Vacuum Heat Treatment of LD Steel Hexagonal Cold Heading Die 8. Seal the double vertical pipe water seal, and pull up the maximum release valve in time according to the furnace pressure.Gear Process Vacuum Heat Treatment Furnace 9. Close the branch pipe air valve and saturated steam valve.Aerospace material vacuum heat treatment furnace
