Quenching and tempering of 45 steel steering knuckle with mesh belt furnace
Product Name: steering knuckle
Material: 45 steel
Requirements: quenching and tempering 235-275hv
Heat treatment equipment: jh802 + jh806 mesh belt furnace production line
Process: 30ml / min atmosphere protection for each route of methanol, zone 1 790, zone 2 840, zone 3 850, zone 4 860, zone 5 860, zone 6 860 ℃, speed about 120 minutes (from furnace feeding to oil feeding time), 60-80 ℃ oil cooling, start stirring, after cleaning, zone 1 350, zone 2 500, zone 3 570, zone 4 570 ℃ tempering for 120 minutes.
1. Lay the product with uniform thickness on the mesh belt and heat it in the furnace
2. Lift up the oil tank mesh belt after oil quenching
3. Measure the hardness after quenching
4. After cleaning, enter the tempering mesh belt furnace for tempering
5. Air cooling after tempering
6. Measure the hardness 235-275hv (22-27hrc) after tempering and use Rockwell rapid test
