三、炉外连续脱硫原理及工艺 1.原理 将具有一定压力和流量的氮气,通过安放在脱硫包底部,由特殊耐火材料及工艺制成的多孔透气砖吹入包内。在氮气泡上升和冷氮气受热膨胀的作用下,使包内铁液呈翻动状态,使铁液与覆盖其表面上的脱硫剂不断更新界面,充分接触进行脱硫反
Third, the continuous desulfurization outside the furnace principle and process 1. Principle Will have a certain pressure and flow of nitrogen through the desalination at the bottom of the package, made of special refractory materials and processes made of porous breathable brick bag. Under the action of the nitrogen bubble rising and the cold nitrogen being heated and expanding, the iron liquid in the bag is turned over so that the molten iron and the desulfurizing agent covering the surface thereof continuously renew the interface, full contact is carried out to desulfurize the anti-sulfur
