To make 2.7*45mm concrete nail

Nail making

Nail polishing

application & features

suitable for light industry, textiles, hardware tools, bearings, chains, standard parts, daily hardware and other industries of ferrous metal parts for bright quenching, thin-layer carburization, carbonitriding and other heat treatments under the protection of a controlled atmosphere. use.

The processed parts have the advantages of bright surface, no decarburization, uniform hardness, and no deformation. The production line also has the characteristics of easy adjustment of process parameters, no pollution, significant energy saving, and high production efficiency.

The total power of the production line is about 299kw, the maximum production capacity is about 200 kg/h for carburizing (within 0.1mm), and about 400 kg/h for quenching. Depending on the size and quality of the product. The installation area of the production line is about 22 meters long, and the layout of the equipment is based on the actual site design basis provided by the demander.

Process flow: 

manual feeding→carburizing and quenching→lifting→cleaning→tempering

Production line equipment composition:

1)Mesh belt quenching furnace,

2)hot oil quenching tank (including hoist and circulating cooler)

3)washing machine and drying

4)mesh belt tempering furnace

5)Electrical control system

Security protection and interlocking system:

The complete set of automatic control system of the above heat treatment furnace has the following alarm protection functions:

1. Furnace temperature over-temperature, under-temperature sound and light alarm;

2. The operation of the mobile furnace body and the electric heating system are interlocked for protection, only when all are in place; the furnace body and bottom electric heating elements can be energized to ensure safe operation;

3. The limit position of the movement of the furnace body is equipped with a safety limit mechanism;

4. The instrument cabinet and furnace body have safety grounding measures to ensure safe use.

5. A safety shield is installed at the power supply connector of the electric heating element.
