初渣的生成与炉料的种类有关。
The formation of primary slag is related with charge structure.
根据相似原理，对高炉滴落带初渣流动进行了区域模拟的实验研究。
On the principle of similarity, the early slag flow in dropping zone is investigated hydraulically with an experimental set-up locally analogues to a blast furnace.
试验研究了从风口喷吹碱性熔剂对高炉炉料软熔性能和初渣性能的影响。
The influence of basic flux injection through the tuyeres on softening-melting properties of blast furnace burden and properties of primary slag was investigated in laboratory.
指出在冶炼过程中炉衬遭损坏的主要原因是初渣的化学侵蚀和精炼期的高温热作用。
It shows that the main causes of lining wear in ferro - chrome smelting process are the chemical erosion by early slag and the thermal effect at high temperature.
还发现，烧结矿碱度过高可能加大滴落初渣与炉腹初渣的碱度差距，对初渣的稳定性产生不利影响。
Moreover, it was found that excessive high basicity of sinter would enlarge the basicity difference between meltdown primary slag and bosh primary slag, worsening slag stability.
由于没有未燃煤粉和煤粉灰分的加入，初渣到终渣的成分变化较小，改善了喷煤气高炉的成渣过程。
Because of absence of unburned pulverized coal and coal ash, the change in composition from primary slag to final slag is small, so the slag formation in gas injection blast furnace is improved.
高炉造渣过程经历初渣、炉腹渣、风口渣和终渣等几个阶段，其中对高炉强化最重要的阶段是炉腹渣。
The slag forming process occurs in stage of primary slag, bosh slag, tuyere slag and tapped slag, among which the most important stage is the bosh slag.
研究结果表明，未燃煤粉以固体质点形式分散在初渣内部时，使初渣粘度大大增加，渣铁熔体难以滴落；
The result shows that the viscosity is greatly increased while the solid coal powder distributed in the inside of slag and result in poor separation of molten iron and slag.
