Large steel bar surface heat treatment production line

Main technical parameters of equipment:

● Power supply system: 160-1000KW/0.5-2.5KHz, hourly output 0.5-3 tons;

● Scope of application: ø 15 – ø 150;

● Energy conversion: quenching mode is adopted, and the power consumption per ton is 260~280 degrees.

● Main purpose: applicable to medium frequency heat treatment of steel bar, low carbon alloy steel, round steel, bar stock, etc;

● Temperature closed-loop control: the quenching adopts the Raytheon infrared thermometer and forms a closed-loop control system with Siemens S7, with high temperature control accuracy;

Advantages and characteristics of steel bar heat treatment production line:

● Good straightness

The production line of remote expansion steel bar induction heating heat treatment is adopted, and the straightening function is designed during the heat treatment process. The steel bar can obtain quite good straightness after heat treatment;

● Uniform heating temperature, high temperature control accuracy, small temperature difference and no pollution

It is easy to detect the change of load current directly and accurately, so as to realize the closed-loop control of output power. The heating temperature control precision of the product is high and the temperature difference between the core and the surface is small, so there will be no harmful gas, smoke and other pollution to the environment during the production process.

● High degree of mechanization and automation

High intelligent power supply, temperature adjustment, automatic tracking of frequency conversion, adaptive load change, automatic power adjustment and other intelligent advantages are “one-button” operation, which truly realizes automatic intelligent induction heating.

● Temperature closed-loop, intelligent, PLC total operation control system

The infrared thermometer measures the heating temperature of the billet at the outlet of the induction heating furnace and monitors whether there is overheating or incomplete heating. To control the blank temperature within the target range. It reduces the generation of nonconforming products and ensures the consistency of product quality.
