The induction billet heating induction heating coil is a contour design. The copper tube is wrapped with T2 oxygen-free copper. The wall thickness of the copper tube is ≥2.5mm. The furnace body insulation material is made of imported materials from the United States. It has high strength, high temperature resistance and long service life. The steel billet secondary heating equipment is packed in a 5mm copper plate with the inlet and outlet ends , which greatly reduces the magnetic leakage and prolongs the service life. The frame structure of the furnace body is made of non-magnetic stainless steel or aluminum alloy to reduce the influence of magnetic flux leakage and heat on other devices. Square steel billet induction heating equipment is equipped with one water-cooled idler roller between each two furnaces. Each roller is equipped with a variable frequency speed regulating motor to ensure stable and uniform operation of the billet.
The billet is driven by the motor and the idler at a constant speed in the induction heater. The billet is heated uniformly, the heat loss is less, and the heating efficiency is high. The discharge port is equipped with the American Leitai thermometer to display the billet heating temperature in real time and keep the workpiece. Uniformity. The slab heating furnace is automatically higher than the general equipment, which is convenient for operation and has a high degree of online intelligence for other equipment. The induction billet is heated and heated evenly. The billet after heat treatment has no cracks, no over-burning, no straightening machine for straightening, tensile strength and toughness, all of which can meet customer needs.

What is the use of induction billet heating ?
Induction slab heating is used as induction heating for billets, billets, round billets, etc. Such equipment generally has other processes behind it, such as heating steel billets and rolling them into steel bars and wire rods.
Induction billet heating price
The industrial use of induction billet heating 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 equipments is different, and the workpieces to be heated by each customer are different. Therefore, the price of the equipment is not the same. When purchasing induction billet heating , you should first locate your own needs and find a larger, professional manufacturer.
How is induction billet heating 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 induction billet heating ?
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 on-line heating and uniform temperature heating of the continuous casting billet byinduction billet heating .
What is the role of induction billet heating ?
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.
