Product Description

The new pure oxygen preheating system for scrap steel adopts pure oxygen combustion technology.

Pure oxygen combustion technology is a new low NOx energy-saving and emission reducing combustion technology. This technology can significantly reduce costs and increase production in the process of electric arc furnace steelmaking, and has broad application prospects.
technological process
Adding scrap steel to the ladle - driving the ladle into the baking station - lowering and igniting the oxygen combustion gun to bake the scrap steel - visualizing the baking of the scrap steel - automatic baking ends - raising the ladle cover and oxygen combustion gun - driving the ladle out of the station - positioning the ladle to the electric furnace outlet to receive molten steel.
Main components
Ultra high power oxygen burner, cover and lifting mechanism, gun body bracket and lifting mechanism, oxygen and gas regulating valve station, electrical automation control system, gas leakage detection and alarm, infrared thermometer, high temperature resistant high-definition camera, flame arrester unit and other equipment.
Technical advantages
Visual combustion technology, preheating simulation design technology, automated one key preheating technology, mixed material preheating technology, gas mixed combustion technology, high-efficiency oxygen combustion gun heating technology.
performance parameter 
(1) Preheating scrap steel weight: 10-20 tons
(2) Preheating temperature: average temperature ≥ 1000 ºC
(3) Preheating time: ≤ 20min
(4) Gas combustion rate: 99%
case
After preheating pure oxygen scrap steel with coke oven gas in a steel plant in Hebei, good results were achieved. At present, the average amount of scrap steel added to the ladle is 10 tons, the preheating time is ≤ 10 minutes, the average oxygen consumption is 22.78m/min, the gas consumption is 28.19mmin, and the heating rate is 74.45 ºC/min. By comparing the manual temperature on site and the temperature collected by the system, under the existing baking conditions, the surface baking temperature of the scrap steel can reach over 1000 ºC.
