3 , billet size range: ( 6mm × 6mm ) - ( 500mm × 500mm )
4 , billet length range: 2 meters or more
5 , the maximum bending degree of the billet before entering the furnace: according to the different types of steel, there are different degrees of curvature. What should I do if the bending degree is greater than 3mm/m before the billet enters the furnace ? The billet secondary heating equipment can meet your requirements by adjusting the size of the sensor according to the degree of bending of your steel.
6, induction of slab surface into the blast furnace and the temperature of the billet furnace temperature: according to the user need to achieve the effect we design and production, blank is heated evenly, without over-burning, no cracks, and the tensile strength of the straight line to achieve the needs of users .
6.1 Control system: The entire heating process realizes PLC automatic control, and timely displays the production records such as the heating quantity. This console is used separately, specially customized human-machine interface, highly user-friendly operation instructions, all-digital, high-depth adjustable parameters, one-button restore function, easy to operate.
6.2 Feeding and guiding system: Each axis independent motor reducer drive, set multi-axis drive, single inverter control, make multi-axis operation synchronous, the device selects well-known brand, reliable quality and stable operation. The 304 non-magnetic stainless steel guide wheel is used to keep the axial direction of the guide wheel moderately flexible to accommodate the bending within the allowable range of the billet.
6.3 Continuous casting steel billet induction heating furnace closed-loop temperature control, the United States Leitai infrared thermometer and Germany's Siemens S7 constitute a closed-loop control system, according to the initial temperature and feed rate of the billet into the induction heater automatically adjust the power supply, so that the heating temperature is Keep it constant before the furnace is released, and the workpiece is heated evenly.
6.4 billet induction heating equipment capacitor cabinet and furnace cabinet separate design (capacitor cabinet position according to user requirements)
6.5 Power supply system: It adopts series resonance IF double-rectification 12-pulse or 24-pulse KGPS1000-1000KW single power supply for independent use or multiple power supply for parallel use. Users can use it with confidence, safe and reliable, energy saving and environmental protection, and easy to operate.
Characteristics of continuous casting billet induction heating furnace:

1 , with series resonant power control, all digital, rectification is fully open, high power factor, small harmonic components.

2 , heating process control: the entire heating process to achieve PLC automatic control, and timely display of various data in the heating process and can save records. .

3 , according to the surface temperature of the blank into the furnace 800 ° C calculation, heating to 1050 ° C per ton of electricity consumption, two IF induction heating power supply.

4, the billet reheating furnace using casting contoured design, brass, oxygen-free copper with T2 wound copper tube wall thickness greater than equal to 2.8mm, U.S. imports furnace insulation materials used ramming mix, high strength, high temperature, Longer service life

5, the billet after the heat treatment, has a good inner compression stress and fatigue of the workpiece have a higher breaking capacity, no crack phenomenon workpiece, tensile strength.

6 , water-cooled roller and retaining roller material: non-magnetic stainless steel, wear-resistant, long service life

7. The inlet and outlet of the billet induction heating electric furnace are installed with the American Leitai infrared temperature measuring device, and the closed loop control is formed by the PLC control system. When the temperature of the billet fluctuates, the output power is adjusted in time to ensure that the temperature of the discharging reaches the heating requirement. And through precise calculation control, the temperature difference between each material is less than 30 degrees. When the furnace is not used for a long time, the power of the furnace will be automatically reduced to the initial power. If the material breaks for more than 10 minutes, it can be automatically stopped (this time can be set according to the actual situation).
What is the use of continuous casting billet induction furnace ?

Continuous casting billet induction heating furnace is used for induction heating such as billet, billet, round billet, etc. Such equipment generally has other processes behind it, such as heating steel billets and rolling into steel bars and wire rods.

The price of continuous casting billet induction furnace

Industrially used for continuous casting billet induction heating furnace can be divided into cold billet heating furnace and billet, continuous casting and online reheating heating furnace according to different customer processes. The power of different equipment is different, and each customer needs to heat the workpiece. It is also different, so the price of the equipment is not the same. When purchasing a continuous casting billet induction heating furnace , you should first locate your own needs and find a larger, professional manufacturer.

How is the continuous casting billet induction furnace precisely controlled?

Adopt two-point temperature measurement. In order to ensure the precise control of the temperature of the billet and the continuous casting billet during the heating process, an infrared thermometer is generally arranged at the inlet and the outlet. In addition, in order to make up for the time difference between the temperature measurement of the thermometer and improve the control sensitivity, a hot body detection device is installed at the inlet and the outlet of each group of furnaces, so that the heating furnace can be more sensitive and reliable in maintaining low power and high power switching without material and materials. .

How to choose the continuous casting billet induction heating furnace ?

The traditional steel rolling process is that the steel slabs obtained by steelmaking are cooled by stacking, transported to a rolling mill, and then heated by a heating furnace to be rolled into steel. This process has two drawbacks. First, the billet is pulled out from the steelmaking continuous casting machine and has a temperature of 700-900 ° C on the cold bed . The latent heat of the billet is not effectively utilized. Second, after the slab is heated by the heating furnace, the surface loss of the slab is about 1.5% due to oxidation loss . The steel-making workshop energy-saving and emission reduction technology transformation project implements continuous casting and rolling for the above problems, but the second point defect is still used in the regenerative heating furnace . In order to fully save energy, it is more suitable to use the continuous casting billet induction heating furnace to carry out on-line heating and uniform temperature heating of the continuous casting billet .

The role of continuous casting billet induction heating furnace ?

The billet warming and heating furnace is a continuous casting billet (small billet, slab, round billet, rectangular billet) which is heated by the heating furnace before entering the rolling mill to realize continuous casting and rolling production. The heating capacity of the whole billet is heated to 1100 ° C , and the temperature uniformity is passed through the induction heating furnace to ensure that the temperature uniformity of the billet is better than the natural state before heating.
