Mesh belt type protective atmosphere automatic continuous quenching heat treatment production line is a continuous heat treatment production line in which the workpiece passes through the temperature controlled heating zone by intermittent advancing mesh belt, then falls into the quenching oil tank, is automatically taken out by the hoist to the mesh belt cleaning machine for degreasing, cleaning drying, then transported to the mesh belt tempering furnace for tempering. It can be used for quenching, thin layer carburizing, carbonitriding other heat treatment processes under controlled atmosphere. In the process of heat treatment, the workpiece does collide with each other, evenly heats through the furnace. Under the action of controllable atmosphere, air intrusion into the furnace is prevented. Therefore, the surface of the treated workpiece is smooth, no decarburization, uniform hardness, small deformation high quality.
It can be used to protect small parts, such as machine tools, metal parts, etc. The quenching brightness isothermal tempering quality are better than the same conventional equipment. It is especially suitable for isothermal quenching of thin steel sheet spring clip. After isothermal quenching, the product quality is stable, the heat treatment performance is improved, the product has no oxidation, good gloss, insufficient soft clip hardness. The problems such as short service life, difficult maintenance, insufficient quenching brightness poor carburizing ability of three heat-resistant steel parts such as muffle can are solved.
Temperature rise of mesh belt quenching furnace:
1. The quenching furnace is heated to 200 ℃ for 2 h;
2. The quenching furnace is heated to 400 ℃ for 2 h;
3. The quenching furnace is heated to 600 ℃ for 2 h;
4. The quenching furnace is heated to 800 ℃ kept at 50 ℃ for 0.5h.
5. Injection of protective atmosphere (only when the furnace temperature exceeds 760 ℃)
Furnace stop steps of quenching belt:
1. Close all valves flow meters on the atmosphere management.
2. Disconnect the power supply of the heating element.
3. When the furnace temperature is below 500 ℃, the speed should be adjusted to 0r / min first, then the power supply of governor mesh belt drive motor should be cut off. Cut off the power supply of all electric appliances in the quenching tank.
