Quenching and tempering of left and right spherical shells of 45 steel with mesh belt furnace
Product Name: left and right spherical shells
Material: 45 steel
Requirements: quenching and tempering 20-26hrc
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. Place 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. Enter the tempering mesh belt furnace for tempering after cleaning
5. Air cooling after tempering
6. Measure the hardness after tempering
