Therefore, due to the fact that the (111) pole density in the subsurface of decarburized bands still have a higher intensity, adding Mo into Hi-B steels could lower the slab reheating temperature.

本文采用X射线极密度和取向分布函数方法，证明含Mo Hi-B钢采用1310℃低温铸坯加热时，其热轧板表层织构特征与不含Mo并在1380℃高温铸坯加热时相似，为典型的剪切形变织构，两者的热轧板与脱碳板表层织构特征也极为相似，而含Mo Hi-B钢在1380℃铸坯加热时却没有以上这些相似性。

As a protective atmosphere for sintering iron base materials, dissociated ammonia is a kind of decarburizing atmospheres.

本文通过热力学分析得出：在烧结过程中H_2与石墨难以形成CH_4，但易从Fe_3C中夺取C；分解氨作为烧结铁基材料的保护气氛是一种脱碳性气氛。

Its subject coverage includes: ladle and tundish technologies to remove inclusions and prevent oxidation; and argon oxygen decarburizing, ladle degassing, filtering, secondary refining, and chemical analysis of slags.

它的主题涉及的范围包括：包和漏斗技术去除夹杂物和防止氧化作用；氩氧气钢的脱碳，包内去氧，过滤，二次精炼法，炉渣的化学分析。

As the concentration of FeO increasing, the rate of decarburizing and reaction-dissolving of refractory rises sharply. Meanwhile gas production rate of reduction reaction is increased and motion and foaming of molten slag are also speeded up. The corrosion feature of refractory containing graphite carbon is that the most severity area is slag level (interface of slag-gas phas -refractory) and slag-metal interface comes second, and the lowest corrosion rate is the area of iron-bath.

熔体的组成、温度及熔体与耐火材料间的相对运动对耐火材料的侵蚀产生着很大影响，而熔渣中FeO浓度是最主要的因素，FeO浓度提高，使耐火材料脱碳和反应熔蚀速度呈直线上升，熔体中还原产生气体量增加，熔体涨泡及运动速度提高，这些作用都加快了熔体对耐火材料的侵蚀。

Moreover, these parts should be shotblasted or sandblasted to remove the scale layer.

此外，这些工件必须经过抛丸或喷沙处理，以去除脱碳层。

I will endeavour to find you some assistance.

At first I only know bruck is the idol of American younglings, afterwards I returned back to Taiwan ,even in Beijing last year ,I saw her poster everywhere, I was so surprised at her charm.

起初我只晓得布鲁克雷德丝是美国少男少女崇拜的偶像，后来回台湾，甚至去年在北京，居然也四处看见她的海报，才惊讶她的魅力之大。
