查询词典 decarburizing

The suitable conditions of quartz sand filtration using for purifying the NHD decarburizing/desulfurizing solution were studied,and sand-bed backwashing method and its intensity were determined.

实验结果表明：在室温，石英砂粒径范围0.60～0.80 mm、床层高度600 mm、操作压力为0.03 MPa以及滤速为8.1 m/h的条件下，NHD脱碳液经石英砂过滤净化处理后，固体杂质去除率可达89.8%以上，且处理后的NHD脱碳液的吸收性能未变。

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。

In the other hand, graphite carbon and SiC oxidizing produce CO、SiO〓 and in the same time CO separates graphite carbon partially, this effect will decrease decarburizing rate and corrosion rate for Al〓O〓-SiC-C brick. TiO〓 and SiO〓 protective layer forming and separating graphite carbon are the main factor of resistance smelting reduction molten slag-iron to corrode and the main feature of corrosion process.

Al〓O〓-C-SiC砖在侵蚀过程中，由于SiC氧化后产生CO，SiO，并析出碳和降低耐火材料气孔率及氧化形成的SiO〓成为保护膜，使熔体对耐火材料的侵蚀能力降低，这两种耐火材料的侵蚀速度都是随着使用时间延长，耐火材料侵蚀速度逐渐降低。

Through adopt the measure such as controling status of hot metal (for example content of carbon, content of oxygen, amount of converter slag, weight of hot metal etc.), depressing degree of vacuum promptly by driving vacuum pump ahead or increasing flow of nitrogen, controling correctly inserted deepness of duck, controling the time of decarburizing, process parameters of decarbonization for managing IF steel using RH—MFB equipment are optimized.

通过严格控制来钢条件，如碳、氧含量，转炉下渣量，钢水量；迅速降低真空室内真空度，采用预真空的压降模式，提高提升气体流量；保证浸渍管插入深度及脱碳时间等措施，优化了攀钢RH—MFB处理超低碳IF钢的脱碳工艺参数，取得了较明显的工艺效果。

They are the strengthening-toughening of 40SiMnCrNiMoA by the critical normalizing, the fine macrostructure and property matching between the all drill rod parts, the low tendency of decarburizing and delete the weak inner hole surface owe to the drill-hole and hot-rolled with core process of rolling steel.

本文研究表明，40SiMnCrNiMoA钢亚温正火强韧化特性、亚温正火使钎杆整体性能良好地匹配、较小的脱碳倾向和钻孔法消除钎杆内孔粗糙和脱碳表面是钻孔法并整体780℃亚温正火+钎柄淬火和低温回火的H22-40SiMnCrNiMoA锥体连接小钎杆延寿的主要原因。

I will endeavour to find you some assistance.

我尽力帮你找人帮忙。

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。
