the high-efficiency and energy-saving technology of flame cutting in steelmaking and continuous casting is a key project that our company has devoted itself to research, development and popularization in recent years. Based on a number of patented products, this technology has been successfully applied in dozens of domestic iron and steel enterprises, which has reversed the disadvantages of high gas consumption, large cutting seam, rough cutting section, much dust in the workshop, heavy noise, heavy environmental pollution, much damage to cutting tools and high labor intensity of workers in the past, showing great energy-saving and consumption-reducing power and excellent environmental protection effect. "High-efficiency and energy-saving technology of flame cutting for steelmaking and continuous casting" is suitable for continuous casting and cutting environment using propane gas, liquefied gas, natural gas, coal gas and hydrogen gas as fuel gas. Main technical and performance indicators:
1. Cutting and slotting: 2.-3.5mm.
2. Gas consumption: 5-9% lower than that of the traditional cutting method (depending on the billet cutting length and usage method).
3. Oxygen consumption: 4% lower than the traditional cutting method.
4. Pollution emission: CO2 emission is reduced by 5-9% compared with the traditional cutting method. The noise is lower than 85dB, reaching the international standard.
5. cutting quality: the cutting section is smooth, the upper edge does not collapse, and the lower edge is not easy to hang slag.
6. Cutting safety: no explosion and tempering, and safe to use.
7. Operating cost: the cutting cost per ton of steel can be reduced to .5 yuan, the tool cost is reduced by 2/3, and the service life is more than 3 times that of traditional products; The system is easy to maintain, saving more than 75% maintenance staff.
