According to your process requirements, we will tailor a suitable billet heating furnace to meet your different needs. The quality of the billet heating induction heating furnace is guaranteed after sale. Welcome to inquire!

[Feeding system] Each axis is driven by an independent motor reducer, multi-axis drive is set, and a single inverter is controlled to synchronize the multi-axis operation.

[Guide system] Adopt 304 non-magnetic stainless steel guide wheel, and keep the guide wheel with moderate elasticity in the axial direction, so as to adapt to the bending within the allowable range of the billet.

The billet heating furnace adopts an intelligent PLC man-machine interface control system with a strong degree of automation. The billet heating furnace is a green, energy-saving and environmentally friendly product. We have rich experience in R&D and production in the field of induction heating equipment, welcome to visit and inspect the company!

The traditional steel rolling process is that the steel billets are stacked and cooled, transported to the rolling mill, and then heated in a heating furnace to be rolled into steel. This process has two defects:

1. After the billet is drawn from the steel-making continuous caster, the temperature on the cooling bed is 700-900°C, and the latent heat of the billet is not effectively utilized.

2. Tom qab lub billet yog rhuab los ntawm lub cua sov rauv, qhov poob ntawm billet nto vim oxidation yog li ntawm 1.5%.

Energy-saving benefit analysis:

1. The coal consumption of the original heating furnace heating billet process is 80 kg/ton of steel (calorific value 6400 kcal/kg), which is equivalent to 72 kg of standard coal; after the technological transformation, the process energy consumption is 38 kWh per ton of steel, which is equivalent to 13.3 kg Standard coal

2. Based on the estimated annual production of steel products of 600,000 tons, the annual savings of standard coal is: (72-13.3) ÷ 1000 × 600,000 tons = 35,220 tons of standard coal.

3. Kev txuag hluav taws xob:

After the billet is drawn from the continuous casting machine, the surface has a temperature of 750-850, and the internal temperature is even as high as 950-1000°C. One of the basic principles of induction heating is the skin effect, which is that heat energy is gradually transferred inward from the surface heating. Above, one-third of the inside of the billet does not need to be heated. According to different billet cross-sectional dimensions, select different frequencies to get better heating efficiency.

4. Cov ntsiab lus txuag hluav taws xob:

a) Lub zog siv hluav taws xob siab ntawm cov cua sov induction tuaj yeem siab li 65 txog 75%, thaum lub tshuab hluav taws xob hluav taws xob ib txwm muaj tsuas yog 25 txog 30%.

b) Qhov saum npoo oxidation ntawm induction cua sov billet tsuas yog 0.5%, thaum lub regenerative cub tawg tuaj yeem ncav cuag 1.5-2%.
