high temperature heat treatment furnace main and auxiliary equipment

High temperature heat treatment furnace main equipment

1. Heat treatment furnace: high temperature heat treatment furnace refers to the heat treatment and heating equipment with furnace. In the heating process, the furnace is first heated, and then participates in the heat exchange of the workpiece, so the heating property of the heat treatment furnace belongs to indirect heating.

2. Heating device: heating device refers to the device that the heat source directly heats the workpiece. Therefore, its heating property is direct heating. The heating method can be that the workpiece is directly fired by flame, the current is directly input into the workpiece to heat it, and induction current is generated in the workpiece to heat the workpiece, plasma, laser and electron beam impact the workpiece and heat it.

3. Surface modification device: this kind of device mainly includes vapor deposition device and ion implantation device.

4. Surface oxidation device: surface oxidation device refers to the device that generates a dense oxide film on the surface of the workpiece through chemical reaction. It consists of a series of grooves, usually called bluing grooves or blackening grooves.

5. Surface mechanical strengthening device: the surface mechanical strengthening device refers to the device that uses metal shot blasting or pressure roller or applies prestress to make the workpiece form surface compressive stress or prestress state, including shot blasting machine and roller press, etc.

6. Quenching and cooling device: the quenching and cooling device refers to the quenching and cooling device for heat treatment, including quenching tanks, jet quenching devices and pressure quenching machines with various cooling media.

7. Cold treatment equipment: cold treatment equipment refers to the equipment used to cool the heat-treated parts to below 0 ℃. The commonly used devices are refrigerator, dry ice cooling device and liquid nitrogen cooling device.

8. Process parameter detection and control instrument: process parameter detection and control instrument, usually refers to the detection, indication and control instrument of temperature, flow, pressure and other parameters. With the application of computer control technology, the concept of heat treatment process parameter control has changed fundamentally. In addition to the conventional process parameter control, there are also static and dynamic control of process, mechatronics control of production process, computer simulation and so on. Computer control becomes the command center of process and equipment operation.
