The holding furnace is a type of material surface that is ignited and burned at high temperature. After leaving the igniter, it is suddenly exposed to the atmosphere, resulting in rapid cooling of the red-hot material surface.Linear Optical Axis Vacuum Quenching Therefore, in the mineral composition of the surface sinter, the glassiness increases significantly. Strength drop, an instrument of this drawback, is an important part of the low pressure casting furnace.Gear Vacuum Carbonitriding It is composed of furnace body, molten pool, sealing cover and liquid riser, and is the basic part of low pressure casting machine.Vacuum Heat Treatment Of Aerospace Aluminum Alloy Materials There are many types of furnaces, such as coke ovens, gas furnaces, resistance furnaces, induction furnaces, etc. The advantages of this type of furnace are simple structure, convenient temperature control and good working conditions. The power of the holding furnace can only make up for the total heat dissipation loss.

How does the heating furnace work? 1. Start the heating furnace: 1. Preparatory work before ignition (1) Wear labor protection supplies, and bring cotton yarn and adjustable wrench for backup. (2) Check the connection points of each part of the gas supply pipeline to ensure that the screws of each part are fully tightened, each gate switch is agile, and the gas supply valve should be in an open state. (3) The level gauge should be clean, complete and clear.Differences in vacuum heat treatment between aerospace blanks and parts (4) The safety valve must be intact and sensitive within the validity period, and the set pressure is 0.1MPa. Step shaft vacuum quenching heat treatment (5) Check the pressure gauge to ensure that the display is sensitive and accurate within the validity period.High speed steel vacuum heat treatment

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
