The induction furnace billet is excellent and technologically advanced. Intelligent series resonance induction heating power supply control, billet heating equipment energy saving 10% - 30%, customized human-machine interface, highly humanized operation instructions, can provide corresponding language switching for different countries and regions, and the operation of billet heating furnace is simple.

The Characteristics of Induction Furnace Billet:

● Provide remote operation console with touch screen or industrial computer system according to user requirements.

● Specially customized human-machine interface and highly humanized operation instructions enable one person to operate the whole set of equipment, saving labor and costs.

● Full-digital, high-depth adjustable parameters, as long as the steel type, size, and equipment of the workpiece are input, the relevant parameters will be automatically called, without manual recording, consulting and input. With high-precision historical curve function. It can be backed up by a USB flash disk or network, and the data can be saved permanently.

● Strict grade management system, the induction heating furnace for square billet is equipped with a one-button reduction system. (If there is a problem with the adjustment, or you want to restore the device to its original state, you can restore the original data by pressing a button.)

The Induction Furnace Billet Adopts Medium Frequency Series Resonant Power Supply to Control Its Characteristics:

1. Parallel resonance design, phase shift and power regulation, mature and stable equipment; It has more advantages in the large power range above 3000KW.

2. DSP control, extremely fast capture phase-locked start, meet frequent start and stop, and high success rate.

3. Variable frequency and load adaptation, frequency adaptation range 200-10000Hz, automatic matching for induction furnace replacement, without any manual adjustment.

4. T2 copper bar is used in the cabinet, which is sandblasted and passivated; Low leakage inductance, anti-oxidation, effectively reducing line loss.

5. Full touch screen control, pure digital setting, complete process records, and strict level authority. Main parameters can be restored to factory settings with one key.

The induction heating coil of the induction furnace billet is of profiling design. The copper tube is wrapped with T2 oxygen-free copper, and the wall thickness of the copper tube is ≥ 2.5mm. The furnace body insulation material is made of knotting material imported from the United States, with high strength, high-temperature resistance and longer service life; The inlet and outlet end of the furnace body of the billet secondary heating equipment is sealed with 5mm copper plates, which greatly reduces magnetic leakage and extends the service life. The furnace chassis frame is made of non-magnetic stainless steel or aluminum alloy to reduce the impact of magnetic leakage and heating on other devices. One water-cooled idler is installed between every two sections of the billet induction heating furnace of square steel, and each idler is equipped with a variable frequency speed control motor to ensure stable and uniform operation of the billet.

The billet runs at a uniform speed in the induction heater driven by the motor and the idler. The heating temperature of the billet is uniform, the heat loss is small, and the heating efficiency is high. The American Leitai thermometer is equipped at the discharge port to display the heating temperature of the billet in real-time and maintain the uniformity of the workpiece. The automatic degree of a billet reheating furnace is higher than that of ordinary equipment, which is easy to operate and has a high degree of online intelligence with other equipment. The billet induction heating furnace is evenly heated, and the billet after heat treatment is free from cracks and overburning, and a straightening machine is not required. The tensile strength and toughness can meet the customer's requirements.

Service Conditions and User-provided Parts of Induction Furnace Billet:

1. The user provides the power supply at the high voltage side of the transformer, the electrical connection line from the transformer to the low voltage distribution cabinet and power supply cabinet, and the incoming line of the operation console.

2. Altitude: ≤ 2000m; Relative humidity: ≤ 90%

3. Equipment cooling: the total flow of the whole equipment is more than or equal to 200 cubic meters per hour. Pressure ≥ 0.3MPa

4. No conductive dust and corrosive gas.

What Is the Billet Induction Furnace Used for?

A billet induction furnace is used for induction heating of steel billets, square billets, round billets, etc. Generally, there are other processes behind such equipment, such as rolling steel billets into steel bars, wire rods, etc.

Induction Furnace Billet Price

In industry, the billet induction heating furnace can be divided into cold billet heating furnace and billet, continuous casting and continuous casting online heating furnace according to the different processes of customers. The power of the equipment is also different for different processes. In addition, the workpiece to be heated by each customer is also different, so the price of the equipment is also different. When purchasing the billet induction heating furnace, we should first position our own needs and then find a large and professional manufacturer.

How to Accurately Control the Temperature of a Billet Induction Furnace?

Two-point temperature measurement is adopted. In order to ensure accurate control of the temperature of the billet and continuous casting billet during the heating process, an infrared thermometer is generally set at the inlet and outlet. In addition, in order to make up for the time difference of temperature measurement by the thermometer and improve the control sensitivity, the thermal body detection device is installed at the inlet and outlet of each group of furnaces, so that the heating furnace can maintain low power and high power switching more sensitive and reliable when there is no material or material.

How to Select the Billet Induction Furnace?

The traditional steel rolling process is that the steel billets from steelmaking are transported to the steel rolling plant after being stacked and cooled, and then heated by the heating furnace before being rolled into steel. This process has two defects. First, the temperature of the billet on the cooling bed is 700-900 ℃ after it is pulled out of the steelmaking caster, and the latent heat of the billet is not effectively utilized. The second is that after the billet is heated by the heating furnace, the oxidation loss of the billet surface is about 1.5%. The energy saving and emission reduction technical transformation project of the steel rolling workshop implements continuous casting and rolling in view of the above problems, but the second defect of using a regenerative heating furnace for heating still exists. In order to fully save energy, it is more appropriate to use the billet induction heating furnace to carry out the online warming and uniform heating of the continuous casting slab.

What Is the Role of Induction Furnace Billet?

The heating furnace for billet heating and temperature compensation is the online heating of continuous casting billet (billet, slab, round billet and rectangular billet) before entering the rolling mill to realize continuous casting and rolling production. Temperature raising capacity The whole billet is heated to 1100 ℃, and the average temperature capacity ensures that the temperature uniformity of the billet is better than the natural state before heating after passing through the induction heating furnace.
