转炉法

The structure of adjustable aditus unit of gas wet purification and recovery system in revolving furnace steelmaking,its working principle were analyzed Compo of control unit and adjustment of control system were introduced The system could automatically adjust jaw opening of aditus of revolving furnace.

对转炉炼钢中煤气湿法净化回收系统的可调喉口系统的结构、工作原理作了分析，并介绍了控制环节的基本组成及整个系统的调试经验。

This rather inefficient performance of the open-hearth , compared with the enormous output of the blast furnace , justified the emergence of the highly productive oxygen process for steel.

与高炉的巨大生产能力相比，平炉效率不高，这就必然促成了大生产能力的氧气转炉炼钢法的出现。

Second, Pyrometallurgical, available blast furnace, shaft furnace, rotary furnace, reverberatory furnace and take them two or three kinds of combination, but there are common problems in the smelting process, the emissions of a large number of products containing lead, sulfur dioxide and other harmful ingredients dust smoke, dust need to configure the corresponding device.

二，火法，可用高炉，竖炉，旋转炉，反射炉，把他们两个或三个种的组合，但也有在冶炼过程中常见的问题，一个含有铅，二氧化硫大量产品的排放量，其他有害成分粉尘烟尘需要配置相应的设备。

Currently the converter steelmaking is the major steel production method in China.

目前 ，转炉炼钢法仍是世界上最主要的炼钢生产方法。

The hot metal pretreatment mode is confirmed as: hot metal － desulphurization by KR in ladle—desiliconization and dephosphorization in converter.

铁水预处理工艺模式确定为：高炉铁水－铁水包 KR 法脱硫－专用转炉脱硅、脱磷。

The smelting of stainless steel has been developed by using powder injection process for desiliconization,dephosphorization and desulphurization of hot metal with pretreatment device,a 30 t EBT UHP EAF for smelting iron alloy and partial scrap,a 75 t K-OBM-S top and bottom combined blown converter and VOD refining at Taiyuan Steel.

太钢开发了通过预处理装置采用粉剂喷吹法对铁水进行脱硅、脱磷和脱硫；以30 t EBT UHPEAF熔化铁合金和部分废钢、75 t K-OBM-S顶底复吹转炉和VOD精炼的冶炼不锈钢工艺，生产能力已达50万t/a。

CaO in the converter slag was examined by petrographic microscopy analysis and its stabilization was investigated in 5～10 mm steel slag through a designed digestion device.

的分布规律，并设计钢渣消解装置对5～10 mm的钢渣进行了转炉钢渣稳定化试验，采用热重法对试验完的物料进行分析。

Top blown oxygen converter adopted recarburization to smelt 45 steel and resolved the end carbon different to control.

为了解决终点碳难以控制的问题，氧气顶吹转炉采用增碳法冶炼45号钢。

We have no common name for a mime of Sophron or Xenarchus and a Socratic Conversation; and we should still be without one even if the imitation in the two instances were in trimeters or elegiacs or some other kind of verse--though it is the way with people to tack on 'poet' to the name of a metre, and talk of elegiac-poets and epic-poets, thinking that they call them poets not by reason of the imitative nature of their work, but indiscriminately by reason of the metre they write in.

索夫农 、森那库斯和苏格拉底式的对话采用的模仿没有一个公共的名称；三音步诗、挽歌体或其他类型的诗的模仿也没有——人们把&诗人&这一名词和格律名称结合到一起，称之为挽歌体诗人或者史诗诗人，他们被称为诗人，似乎只是因为遵守格律写作，而非他们作品的模仿本质。

The relationship between communicative competence and grammar teaching should be that of the ends and the means.

交际能力和语法的关系应该是目标与途径的关系。
