Common production desk vice, 45 # steel make the clamp plate, how to make pattern
I don't understand the pattern. In heat treatment, the size is smaller, and the temperature of the heat is increased by the maximum power of the furnace. The furnace controls the clearance. The heat preservation time of 30 min, oil cooling, 500 ℃ tempering, 1 h
The heat treatment process can not be detailed, such as the control of temperature rise, the control of the insulation time, the small size of the small size 20 * 25 * 200 small steel bars, a batch of about 300Kg
45 # steel jaw plate, heat treatment at 860 ℃ quenching, quenching oil cooling water, 500 ℃ tempering hardness in HB300-350, can satisfy the requirement of general hardness and toughness.
