Quenching of 65Mn elastic clip with mesh belt furnace
Product Name: elastic clip
Material: 65Mn
Requirements: quenching 44-46hrc
Heat treatment equipment: jh802 + jh806 mesh belt furnace production line
Process: 30 ml / min of methanol per route, atmosphere protection, and 400L / h of gas to raise the carbon potential to about 0.65, so as to avoid that decarburization can not produce hardness. Zone 1 770, zone 2 820, zone 3 830, zone 4 8405, zone 840, zone 6 840 ℃, the speed is about 80 minutes (from furnace feeding to oil feeding time), 60-80 degrees oil cooling, turn off stirring, after cleaning, tempering at 250, zone 2 350, zone 3 410, zone 4 410 ℃ in zone 1 for 90 minutes.
1. Lay the product with uniform thickness on the mesh belt and heat it in the furnace,
2. After oil quenching, the oil tank mesh belt is lifted up,
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 after tempering
