steel scale

Foundation excavation with considerable scale and depth of Oriental Plaza project is of tremendous construction difficulty. Pouring piling was adopted to enclosure structure ( partly with steel of H section);

北京东方广场深基坑工程开挖范围、深度和施工难度大，围护结构采用钻孔灌注桩（局部H形钢桩），锚杆加土钉形成复合支撑；

EPMA and TGA were used to explore the high temperature oxidation behaviour of the low carbon steel under oxidant gas condition with different oxygen content. The oxidation activation energy and growth morphology of the scale were obtained.

利用EPMA和高温差热分析仪（TGA），针对低碳钢在不同氧含量的氧化性气氛的高温氧化行为进行了系统研究，获得了实验钢的氧化激活能和氧化铁皮生长形貌。

Because of the existing difficult problem of on-line weighing of rolled-products all along, an on-line electron roller scale was developed for hot rolled strip by Baotou Iron and Steel ( Group) Co.

针对钢坯或轧材的在线称量难题，包头钢铁（集团）公司研制了热轧带钢在线电子辊道秤；

Stainless steel products finish machining for large scale exhibition hall.

大型展厅、展会不锈钢制品精加工.

Now let us briefly look at some large-scale technological developments, starting with iron and steel making.

下面让我们再简单谈谈开始于钢铁制造的大规模技术的发展情况.

大型钢结构平台的安装及防变形措施

Use: SCS-IPDouble Platform Buffer Steel Scale is applied to the warehouse and the metallurgical industry.

用途: SCS-IP系列双台面缓冲钢材秤适用于冶金、仓库等行业.

And the related domestic research institutes, scale steel mills established a close cooperation relationship.

并与国内相关的科研院所 、 大型钢厂建立了密切的协作关系.

A scale of rust covered the steel plate.

一层铁锈覆盖了钢板.

The main points of chemical composition and cleanness control were listed and the terminal point control as well as low nitrogen control technology of EAF was developed. It was found that there existed nano-scale sulfides, oxides, nitrides and carbides in HSLC steel.

提出了HSLC钢的成分控制要点，开发了电炉终点碳控制和低氧控制技术，发现了低碳钢中存在纳米硫化物、氧化纳、氮化物和碳化物。
