炉料

In February, 2004, Chongqing Sinosteel Charging Co., Ltd which has been in wested by sinosteel Investment Group.was formally established,marking a starting point of the engagement in the iron and steel industry

2004年2月中钢投资公司投资成立中钢炉料有限责任公司，标志着从事钢铁原材料行业的伊始

And the production had proved that in the present technological conditions before ironmaking,the sinters (70%～75%) with 1.7～1.8 basicity adding (about 25%) acid pellet and a few lump ores are the reasonable.

生产实践证明，在莱钢铁前现有工艺装备条件下，碱度为1.7～1.8的烧结矿（70%～75%）配加酸性球团矿（约25%）及少量块矿是较为合理的高炉炉料结构。

The heat air sintering and the constitution of blast furnace burdens and the hybrid pelletized sinter process have been studied in laboratory.

在实验室中，对低温热空气烧结、高炉炉料结构以及混合球团烧结工艺进行了比较系统的研究。

Of raw materials to make ALE Series Stroke Stop and Stroke Switch use of carbon steel, ordinary gray cast iron or ductile iron back to BURDEN; reduce the liquid iron in the alloy elements such as Cr, Mn and other content, reducing its molten iron-containing gas; before the next core sand core all the overhead brush paint and the storage period to prevent the sand core to absorb moisture; in rainy days or high humidity of the season, the next best to use torch to the former core cavity, the surface of sand core baking again, in order to reduce sand-fat content; high-temperature casting a small valve in order to facilitate their own exhaust and the reduction of molten iron casting slag produced.

6原料尽量使用碳钢、普通灰铸铁或球墨铸铁回炉料；降低铁液中的合金元素如Cr、Mn等含量，减少铁液自身含气量；将下芯前的砂芯全部架空刷涂料且限期存放，以防砂芯吸潮；在阴雨天或湿度较大的季节，下芯前最好用喷灯将型腔、砂芯表面烘烤一遍，以减少砂型发气量；采用高温浇注小阀门，以利于铁液自身排气和减少铸渣产生。

When the charge formula among concentrate, sodium carbonate and coal powder is 100:50:10, the temperature is 980℃, time is 60 min, the direct recovery rates of main metals are that 92.29% Pb, 79.82%Sb and 84.94%Ag, the slag ratio of metals for Pb, Sb, Ag, In, Zn, Cu and Fe are 5.00%, 3.21%, 8.97%, 69.76%, 95.28%, 78.00% and 87.74% respectively, the grade of sodium sulphide in the slag is 52%, the slag ratio is 62.4%.

炉料配方为精矿：纯碱：煤粉＝100：50：10；温度为980℃，时间为60 min时，各主要金属直收率分别为：Pb 92.29、Sb 79.82、Ag 84.94，金属入渣率分别为：Pb 5.00、Sb 3.21、Ag 8.97、In 69.76、Zn 95.28、Cu 78.00、Fe 87.74，熔炼渣中硫化钠品位为52%，渣率为62.4%。

The mechanical vib r ation during the operation of the kiln and the attack of the furn a ce filling will damage the kiln greatly.

三是回转窑运行时的机械振动及炉料砸击研磨破坏。

In basic refining operations lime is added to the stock to form a basic slag, which can combine with phosphorus and sulphur, thus removing them from the metal.

在碱性法精炼过程中，炉料加有石灰，能生成碱性渣，而碱性渣能与磷，硫生成化合物，从而将磷和硫从钢水中除去。

Since historical times,England ,where the early inhabitants were Celts, has been conquered three times .

从有历史以来，英国，在此地早期居住的是凯尔特人，已经被征服了三次。
