炼铁

From moment to moment, some huge vehicle, painted yellow and black, heavily loaded, noisily harnessed, rendered shapeless by trunks, tarpaulins, and valises, full of heads which immediately disappeared, rushed through the crowd with all the sparks of a forge, with dust for smoke, and an air of fury, grinding the pavements, changing all the paving-stones into steels.

每隔一分钟，就会有一辆刷了黄漆和黑漆的大车，载着沉重的东西，马蹄铁链响成一片，箱、箧、提包堆到不成样子，车子里人头攒动，一眨眼全都走了，碾踏着街心，疯狂地穿过人堆，路面上的石块尽成了燧石，尘灰滚滚，就好象是从炼铁炉里冒出的火星和浓烟。

By the comparison and demonstration of some sinters quality and indexes of blast furnace of several representative corporations, the viewpoint that ironmaking personnel must bring an new conception of sinter quality into 21th century was proposed.

本文阐述了建国五十年来烧结矿质量进步与高炉操作技术发展的三个阶段，通过几个有代表性企业烧结矿质量与高炉操作指标的对比分析和论证，提出了炼铁工作者应把一个烧结矿质量新概念带入二十一世纪。

The results show that without or with small amount of MgO in burden, the sintering productivity can be improved, and the sinters have high cold strength and narrow temperature range of cohesive zone.

MgO对烧结工艺以及烧结矿强度、低温还原粉化性能、高温软化熔融性能等的影响已有大量研究_1 ，但缺乏系统地考察MgO对整个烧结一高炉炼铁工艺全流程的影响。

The high temperature metallurgical properties of several burdens for Anyang steel were investigated. The results showed that RIof high basicity sinters was better than others, but the RDI(low temperature reduction degradation index) of it was the highest; the RDI and molten dripping property of pellets and lump ores were well, so we can get rational burden structure by combining sinters for blast furnace.

系统分析了安钢炼铁生产中几种常用炉料的高温冶金性能，结果表明，安钢自产高碱度烧结矿具有较好的还原性，但其低温还原粉化率却是最高的；酸性球团矿及块矿则有着较好的低温还原粉化指数及良好的熔滴性能，能够与高碱度烧结矿搭配形成合理的综合炉料结构，满足高炉冶炼要求。

This has certain reference meanings to recirculating cooling water treatment in iron and steel corporation.

作为钢铁企业里的炼铁、炼钢、连铸及轧钢等主体设备的循环冷却水，在整个行业用水中所占的比重最大，因此，有必要加强对循环冷却水处理技术的研究。

During this time the business adopted a strategy of cultivating family alliances to consolidate the iron works in Belfort, about 35 miles north of Toulouse.

在此期间，企业采用建立家族联盟的策略，并购 Toulouse以北 35英里处的 Belfort的炼铁企业。

There are four parts presented in this paper. In the first part, the B.F ironmaking process, B.F Expert System and the methods to predict the silicon content in molten iron are introduced. In the second part, the control parameters and state parameters of B.F ironmaking process are analyzed. In the third part, the Statistical Learning Theory and Support Vector Machine are introduced.

论文主要包括以下四个方面的内容：高炉炼铁、高炉专家系统和炉温预测的概述；高炉冶炼过程状态参数和控制参数的分析；统计学习理论和支持向量机方法；基于支持向量机的铁水硅含量数值预报模型和铁水硅含量多类别分类模型。

However, as the name（read－only memory）implies, CD disks cannot be written onorchanged in any way.

然而，正如其名字所指出的那样，CD盘不能写，也不能用任何方式改变其内容。
