Complete Quenching & Carburizing Process Details
High-temperature gas carburizing paired with rapid liquid cooling quenching improves metal hardness, wear resistance and anti-corrosion property to extend service life of fastener parts.
- Step 1: Segment preheat furnace from 300℃ to 900℃, hold constant temperature to remove internal water vapor
- Step 2: Heat up to 830℃, cut off heating & kerosene supply, feed raw fasteners into sealed furnace tank
- Step 3: Raise temperature to 870℃, ignite waste exhaust gas to build sealed protective carburizing atmosphere
- Step 4: Cool furnace to 800℃, close kerosene valve, tilt furnace body to automatically discharge hot workpieces
- Step 5: Drop hot parts into water quenching medium mixed with sodium nitrite for anti-rust & uniform hardening effect
- Step 6: Cool workpieces down to 150-200℃, soak in anti-rust black oil then air-dry finished fasteners
- Step 7: Extend tempering holding time properly to boost part toughness if hardness is excessive
