摘要
在1300℃研究了实验条件对石灰基渣系铁水同时脱磷、脱硫的影响。结果表明,炉衬耐火材质、载气、渣量和处理时间对脱磷、脱硫均有重要影响。MgO和MgO-11％Al_2O_3等碱性物质可作铁水预处理的耐火材料,空气和氧气都可作为喷吹渣剂的载气。短时处理和少渣均可实现一定程度的同时脱磷、脱硫。
The effect of experimental conditions on simultaneous dephosphorization and desulfurization of hot metal with lime-based fluxes was studied at 1300℃. The results show that the lining-refractory, carrier gas, flux amount and treating-time affect dephosphorization and desulfurization seriously. Both MgO and MgO-11%A12O3 can be used as the refractory for the pretreatment of hot metal. Compressed-air and oxygen can be the fluxes-blowing carrer gases. Short time and a little amount of fluxes can result in simultaneous dephosphorization and desulfurization to some extent.
