冶炼

The retrofitting of control system for gypsum centrifuge in swage treatment system of a copper smelter acid plant is described.

介绍铜冶炼烟气制酸装置废水处理系统石膏离心机控制系统的改造。

Taphole drill is the general equipment in the taphole plant .It is used to used to open the tahole, and to complete ironmaking in furnace.

开铁口机是炼铁厂的一种常用设备，其功能是用来打开高炉铁口，实现现代化高炉冶炼。

Pansteel Blast Furnace used simply electric taphole drill for a long time,which cannot apply to higher smelting intensity and the new clay gun.

攀钢高炉炉前开铁口设备一直使用简易的电动开铁口机，已不适应高炉高强度冶炼和铁口新型炮泥的要求。

In order to increase the hot metal throughput of main trough, some reforms to the trough were carried out, and in order to realize zero-interval tapping and meet the needs for smooth operation and intensified smelting of BF, the management and maintenance of taphole were strengthened at Maanshan Steel's 2500 m~3 BF.

马钢2500m~3高炉通过对渣铁沟进行技术改造，增加了主沟通铁量；通过加强铁口管理与维护，实现了零间隔出铁，满足了高炉强化冶炼的需要。

Through test and analysis, it is believed that the main cause of failure of the short inlet pipe of main platen header is low smelting purity and high impurity content of steel, and original cracks formed by concentrated impurity along the pipe longitudinally during rolling, which leads to tear-off.

通过试验，分析部件失效原因为：钢材冶炼纯净度低致使夹杂物超标，在随后的轧制过程中形成沿管子纵向分布的密集夹杂物构成的原始裂纹，从而导致开裂。

The result indicates the size composion of tuyere coke changes little,porosity increase and theremal strength reduce,with increase of smelting strength .

通过对攀钢高炉不同冶炼强度下风口焦和相应的入炉焦的粒度组成、冷热强度、化学成分、气孔率的比较、分析。

In the process of mining, milling and steel and rare earth melting, thoron element was released to the accessible environment together with smoke, wastewater and disposed slag, leading to radioactive contamination to the environment.

在采矿、选矿、钢铁和稀土冶炼等生产中，钍元素随烟尘、废水和废渣排放至环境中，造成放射性污染。

But the output of the tungsten products was still less than 2,000 tons.

这一期间赣州钨冶炼产品产量很小，年总产量不到2000吨。

It is critically important that the materials, security and service life of the tuyere are successfully prepared.

所以，高炉冶炼工鬃者对高炉风口的选材、制造、安全性和使用寿命等方面都极为关注。

Our company has achieved the per year production capability of 100,000 ton smelting pig iron,35,000 ton of vermicular cast iron and other kind of cast iron and cast steel work.We can do forge,heat treatmeant and machine processing of all kinds of cast steel work below 25ton.

目前，该公司已形成年产十万吨冶炼生铁，3.5万吨蠕墨铸铁件的生产规模，可承接25吨以下各类材质铸件的铸造、热处理和机加工。

As she looked at Warrington's manly face, and dark, melancholy eyes, she had settled in her mind that he must have been the victim of an unhappy attachment.

每逢看到沃林顿那刚毅的脸，那乌黑、忧郁的眼睛，她便会相信，他一定作过不幸的爱情的受害者。

Maybe they'll disappear into a pothole.

也许他们将在壶穴里消失
