天津钢管公司配备了一套脱硫粉剂输送及喷吹设备。该系统设有2个不同容积的贮料仓,可以装载不同配比的粉料,粉料经溜管到气力发送罐,再由其在气体带动下压送到喷吹罐系统,并通过喷吹罐将粉料压送到多功能顶枪而喷入RH真空槽内,从而达到喷吹脱硫的作用。通过反复生产运行,在喷吹粉剂总量为1000 kg时,喷吹速度达到222.2 kg/min,经脱硫后钢水中硫质量分数在20×10-6左右,脱硫率在50%以上,满足了喷粉脱硫工艺的要求。
Tianjin Pipe Company is equipped with a desulfurization powder conveying and blowing equipment. The system is equipped with two different storage silos, can be loaded with different proportions of powder, powder through the tube to the pneumatic transmission tank, and then under the gas pressure sent to the injection tank system, and through the spray Blowing the powder pressure to the multi-function powder gun and injected into the RH vacuum tank, so as to achieve the role of injection desulfurization. Through repeated production and operation, the blowing speed reaches 222.2 kg / min when the total amount of powder is 1000 kg, the sulfur content in the molten steel after desulfurization is about 20 × 10-6 and the desulfurization rate is above 50% Dusting desulfurization process requirements.
