Therefore, refinement with C〓Cl〓 and N〓 promotes formation of primary iron-rich phases but does not coarsen them.

因此，吹气和精炼虽然强烈促进初生铁相的形成，但不易使铁相粗大化。

The preventive measures for the harmful defects of alkali metals are as follows: 1, reducing the alkali metals content in the raw materials; 2, increasing the MgO content of the sinter , decreasing the basicity of slag , decreasing the Si content of the pig iron, increasing relative slag volume; 3 , introducing prereduced ore pellets or partly reducted sinter; 4increasing the ability of coke resisting alkali metals; 5, using refractories that have the ability of resisting corrasion of alkali metals; 6 , cleaning the blast furnace periodically. The above recommendations are necessary for decreasing the circulation and accumulation of alkali metals effectively in blast furnace, reducing the harmful influence of alkali metals on blast furnace, increasing the smelting intensity, decreasing the coke rate, improving the gas permeability.

基于碱金属对高炉冶炼的上述危害，本文结合湘钢高炉的实际生产情况，通过理论分析、计算以及其他钢厂防治碱害的经验，提出防治高炉碱害的措施：1、减少入炉原、燃料的碱金属含量；2、提高烧结矿中的MgO含量、降低炉渣碱度、降低生铁含硅量、适当增加渣量；3、采用预还原的金属化球团或部分还原的烧结矿；4、提高焦炭的抗碱能力；5采用抗碱侵蚀的耐火材料；6、周期性性洗炉，以有效地减少碱金属在高炉内的循环富集，降低碱金属对高炉的危害，提高高炉的冶炼强度，降低焦比，改善高炉透气性。

Then, maneuvering that iron stove through that doorway, with another mighty grunt Pete just heaved it forward and outward, and it smashed down against her little grassy-patched dirt back yard, the sounds of the crash and the iron cracking open sending her little spotted feist dog and her few any-breed chichens all yelping and squawking and flying.

句子翻译：然后，彼特搬着铁炉走出门口，又大喝了一声，举起铁炉向前往外抛去，顿时落在她乱草丛生的小后院，摔成碎片。撞击声和生铁的破裂声把她的小花狗和几只小鸡吓得咯咯大叫，四散飞逃。

The triboelectrostatic beneficiation experiments have been done based on the research of floatability, dielectric constant and mineral components.

在对3种煤的浮沉性能、介电常数、矿物成分研究的基础上，进行了摩擦电选实验研究，应用摩擦电选技术结合喷煤系统的特点，进行炉前降灰具有工艺和技术的合理性，降低高炉喷吹用煤的灰分有利于提高煤比、降低焦比及生铁成本。
