Steel billet secondary heating furnace product manufacturing standards:
1 , JB4086-85 "Technical conditions for the application of electronic control equipment for medium frequency sense"
2 , GB10067.3-88 "Basic technical conditions of electric heating equipment , induction electric heating equipment"
The slab secondary heating furnace is controlled by an intermediate frequency series resonant power supply:
● Parallel resonance design, phase shifting and power adjustment, the equipment is mature and stable; it has more advantages in the high power range above 3000KW .
● DSP control, the speed capture lock phase starts, meets frequent start and stop, and has high success rate.
● Variable frequency variable load adaptation, frequency adaptation range 200-10000Hz, induction furnace replacement automatic matching, no manual adjustment is required.
● T2 copper copper row in the cabinet , sandblasted and passivated; low leakage and anti-oxidation, effectively reducing line loss.
● Full touch screen control, pure digital setting, complete process record and strict hierarchical authority. The main parameters can be restored to the factory settings with one key.
● Power single unit power 50-6000KW , frequency 200-10000Hz.
The induction heating coil of the billet secondary heating furnace 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 insulation material of the furnace body is made of imported materials from the United States. It has high strength, high temperature resistance and long service life. Longer; the steel billet secondary heating equipment furnace body inlet and outlet end is sealed with 5mm copper plate, which greatly reduces magnetic leakage and prolongs 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. Each of the two furnaces is equipped with a water-cooled idler roller, and each roller is equipped with a variable frequency speed regulating motor to ensure stable and uniform operation of the steel 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 billet secondary heating furnace is fully automatic intelligent control by the PLC remote control of thehuman-machine interface , strict hierarchical management system, perfect one-key reduction system, all-digital, high-depth adjustable parameters, and highly humanized operation instructions.
What is the use of the billet secondary heating furnace ?

The billet secondary 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 the billet and rolling it into steel bars and wire rods.

Billet secondary heating furnace price

The secondary heating furnace for steel billet in the industry can be divided into cold billet heating furnace and steel billet, continuous casting and online heating furnace according to different customer processes. The power of different equipment is different, and each workpiece to be heated by customers is also Different, so the price of the equipment is not the same. When purchasing the secondary billet of the billet , you should first locate your own demand and find a larger, professional manufacturer.

How is the steel billet secondary heating 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 billet secondary 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 steel billet secondary heating furnace for on-line heating and uniform temperature heating of the continuous casting billet.

The role of the billet secondary 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.
