大冶钢厂在12??,20??_3?,18???,18??,40??等钢冶炼上试验采用新氧化法——吸取返回单渣冶炼法单渣经验及氧化法的脱磷长处,采取氧化期首先矿石脱磷扒渣,然后造渣吹氧去气再带渣进入还原期。试验分两个阶段:第一阶段试验了18????1炉,18???3炉,12??3?2炉,12?_2?_4?1炉,40??3炉,这一阶段试验的操作特点在于氧化期均采用综合氧化(即前期采用矿石,后期采用氧气,脱炭量前后期约各为一半)。总脱炭为_0.3%;矿石氧化完毕,F~0.015%,全部扒渣造新渣开始吹氧氧化。氧化完毕,如P~0.01%,则全单渣进入还原,
Daye Steel Plant in 12, 20 ?? _3 ?, 18 ??, 18 ??, 40 ?? and other steel smelting test on the use of new oxidation method - drawing back single slag smelting single slag experience and oxidation method Of the dephosphorization strengths, to take the first dephosphorization of ore dephosphorization slag, and then slagging oxygen and then bring the slag into the reduction period. The test is divided into two stages: the first stage of the test 18 18 furnaces, 18 3 furnaces, 12 3 2 furnaces, 12 2 _2 4 1 furnaces, 40 3 furnaces, which The operational characteristics of the first phase of the experiment are characterized by comprehensive oxidation oxidation period (that is, the early use of ore, the late use of oxygen, carbon off the amount of about half before and after). The total off-charcoal as _0.3%; ore oxidation is completed, F ~ 0.015%, all slag-making new slag oxygen oxidation began. Oxidation is completed, such as P ~ 0.01%, then the entire single residue into the reduction,
