2 , GB10067.3-88 "Basic technical conditions of electric heating equipment , induction electric heating equipment"
Advantages of selecting billet online heating and heating furnace :
1. The billet online heating and heating electric furnace has different degrees of bending according to different workpieces of steel. If the bending degree is more than 3mm/m before the billet enters the electric furnace, you can adjust the size of the sensor according to the bending degree of your steel to meet your requirements.
2 , slab on-line heating and heating furnace surface before entering the furnace temperature and billet exit temperature: according to the user's needs to achieve the design and production, the billet heating evenly, no over-burning, no cracks, tensile strength and straightness can reach users Demand.
3 , the entire heating process of the billet heating equipment realizes PLC automatic control, and timely displays the production records such as the heating quantity. This console is used separately, with a customized man-machine interface, highly user-friendly operation instructions, and simple operation.
4 , feeding and guiding system: each axis independent motor reducer drive, set multi-axis drive, single inverter control, so that multi-axis operation synchronization, the device selects well-known brands, reliable quality, 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.
5 , billet online heating and 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 Keep it constant before the furnace is released, and the workpiece is heated evenly.
6. The billet heating furnace adopts series resonant intermediate frequency double rectification 12-pulse or 24-pulse KGPS100-1000KW 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.
What is the use of billet online heating and heating furnace ?
The billet on-line heating and heating electric furnace is used for induction heating such as billet, billet and round billet. Such equipment generally has other processes behind it, such as heating the billet and rolling it into steel bars and wire rods.
Billet online heating and heating electric furnace price
The industrial online heating and heating electric furnace for steel billet 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 It is also different, so the price of the equipment is not the same. When purchasing the billet online heating and heating electric furnace , you should first locate your own demand and then find a larger, professional manufacturer.
How is the billet online heating and heating electric 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 steel billet online heating and 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 slab in-line heating and heating electric furnace to carry out on-line heating and uniform temperature heating of the continuous casting slab.
The role of billet online heating and heating electric 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.
