查询词典 coke pig iron

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。

At the same time, the content of MgO of BF slag to increase 0.35 % reached 7.8-8.0%,the meltability temperature and viscosity of slag reduced, the fluidity of slag from 115mm impromed to 170mm, the iron loss from 7.09% decreased 5.15%, pig iron yield decreased 18t/d ,and comprehensive coke ratio declined 6.57kg/tp by indexes correction, effects of saving coke was significant ,and technical parameters of sinter and BF were optimized and improved,so that the content 7.8-8.0%of MgO of BF slag is suitable level.

高炉渣中MgO 含量提高0.35%达到7.8-8.0%，炉渣熔化性温度与粘度下降，炉渣流动性由115mm提高到170mmm，铁损由7.09%降低到5.15%，校正后产量小幅了下降18t/d，但综合焦比下降了6.57kg/tP，节焦效果显著，同时烧结与高炉的工艺参数得到优化与提升，炉渣MgO含量7.8-8.0%为较适宜水平。

Heng Bo supplies seamless pipe, senior market analyst, said: At present the majority of iron inside the steel-making pig iron inventories not try for the impact of the demand by the steel mill, a lot of iron re-turn to the production of pig iron for steel-making, according to Iron Works to reflect , due to increased market demand for raw materials and coke prices up, market confidence has been restored, but the production of iron cast iron is still no intention to resume, the market demand will soar to a height of what the market is not expected to unity, on the current situation, the prudent operation of the steel-making pig iron is still the main way to run.

恒博物资的资深无缝管市场分析师表示：目前多数铁厂内炼钢生铁库存量不大，受钢厂需求拉升影响，很多铁厂再度转向对炼钢生铁的生产，据铁厂人士反映，由于市场需求加大和焦炭等原料价格的上行，市场信心有所恢复，但停产的铁厂暂时还没有恢复生铁的打算，市场需求会升到一个什么样的高度，市场预期并不统一，就目前的形势来看，谨慎操作依然是该炼钢生铁运行的主要方式。
