焦炭生铁

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。

The company mainly dealsn of capita managernent,project investment guarantee, real estate project as wel as domestic and foreign business of vanous ferrous metals and metallurgical materas such asconstruction steel, ingot iron, mineral sand, coke, heavy oi, etc.

And coke, pig iron, the export business.

及焦炭，生铁，的外销业务。

The company is fully committed to growing its imports and exports business areas of specializations include: steel, wood, building materials, anchor chain, pig iron, iron ore powder, billet, steel ingot, ferroalloy, charcoal, fireproofing materials, hardware, electric devices.

公司经营范围：钢材、木材、建材、锚链、生铁、铁矿粉、钢坯、钢锭、铁精粉、铁合金、球团、焦炭、耐火材料、五金交电；化工产品、服装、日用百货、儿童玩具、办公自动化设备的批发零售；冶金机械备件加工销售、冶金机械设备维修、废旧金属回收、自营和代理各类商品和技术的进出口。

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。

Main management: nonferrous metals, ferroalloy, sand series, pig iron, coke, waste metal, waste stainless steel (304,316) and casting equipment (smelting unit, core making equipment, shakeout equipment, cleaning equipment, sand preparing machine, moulding equipment, self-setting resin sand and silicate-bonded sand equipment, various instrument and meter), spares.

On the other hand, the more important thing is because the urban housing is a kind of heterogeneity products.

另一方面，更重要的是由于城市住房是一种异质性产品。

Climate histogram is the fall that collects place measure calm value, cent serves as cross axle for a few equal interval, the area that the frequency that the value appears according to place is accumulated and becomes will be determined inside each interval, discharge the graph that rise with post, also be called histogram.
