Su steel smelting has two advantages:(1) During the pouring process there is strong oxidation which results in separation of slag and iron the wrought iron being soft in structure and containing large amounts of oxide impurities and also silicon manganese and carbon.

蘇鋼冶煉高明的地方主要有二點：一是料鐵組織疏松，含有大量的氧化夾雜色色色色色综合视频，硅、錳尤物成人最新电影在线观看免费网站、碳含量也比較高免费观看黄色视频的网址，煉的時候氧化劇烈，造成一定的渣西西WWW大胆高清视频、鐵分離www.中文字幕在线播放。

This research is a new low cost method of producing abrasive grit. It is to put the iron ore concentrate, coal powder, hydrated limed and addition agent together to make coal mixed pellet in prior which is rapidly auto-reduced in high temperature and kept about 10min above 1350℃, and then furnace cooled. The 2CaO·SiO2 of slag phase change、volume increase and natural bloom in reduction process. Finally we obtain no-slag abrasive grit through screen separation , in which the iron yield can be above 90%,the sulfur content can be below 0.05% and carbon content is lower than 4.0%.

本研究是一種全新的低成本生產(chǎn)鐵粒的方法日韩精品欧美精品国产精品，它是將鐵精粉一级香蕉黄片、煤粉、消石灰和添加劑預(yù)先制成球團扒开双腿疯狂进出爽爽爽网站，在高溫下迅速加熱還原久久精品国产99精品最新按摸，在1350℃以上保溫10分鐘后隨爐冷卻，渣相中2CaO·SiO2在冷卻過程中發(fā)生相變人人操人人湿人人干，體積膨脹而自然粉化福利视频黄，通過篩分便可以得到不含爐渣的鐵顆粒，鐵的收得率在90%以上欧美一级在线观看欧美大片、S≤0.05%思思99思思久久最新精品、C在4.0%左右。

The results show that magnesium and aluminum theoretically can be thoroughly dissolved from the blast furnace slag by diluted sulfuric acid pretreatment on the blast furnace slag even if the ended concentration of sulfuric acid is 0.001mol/L, while the titanium basically could not be dissolved. Therefore it is theoretically indicated that the separation of the magnesium and aluminum from the slag with the least titanium loss by diluted sulfuric acid pretreatment is possible.

結(jié)果表明jjzz中国jjzz，采用稀硫酸對高爐渣進行預(yù)處理www、αV、COm，當(dāng)終酸濃度即使為0.001mol·l~(-1)時，鎂国产91九色、鋁理論上也能全部被酸浸出色色视频网页大全，而鈦在0.001 mol·l~(-1)的酸濃度條件下基本不被浸出，從而從理論上可以說明對高爐渣采用稀酸預(yù)處理可以很好的將爐渣中的鎂一区二区亚洲黄色网站、鋁等雜質(zhì)分離出來欧美精品AAAAAAA，而鈦極少被浸出。
