Drive a vehicle of 1 foreword 125/32t is my factory the crucial equipment of molten steel of a swing, main task is seasonable transmitting; of stage of packets of Lian Zhu is big circumgyrate smoothly is the most crucial one annulus on steel-making production catenary, once have an accident, can suspend steel-making production, bring about blast furnace even cease wind, of this equipment move smoothly, very important.

梗概： 1引言125/32t行车是我厂一台吊运钢水的关键设备，主要任务是及时将转炉出来的钢水平安、平稳地转送到连铸大包回转台；是炼钢生产链上最关键的一环，一旦出事，会中断炼钢生产，甚至导致高炉的休风，这台设备的平稳运行，非常重要。

On the basis of experimental data, by the aid of boundary-element method, the temperature distribution, temperature gradient and colling velocity in the casting region ran be calculated.

本文建立了铝在双辊式铸轧时铸造区温度场的数学模型，根据实验数据用边界元法计算出铸造区的温度分布、温度梯度和冷却速度。

The composition of TB6 alloy ingots after heat treatment then water colling and air colling was analyzed. The results show that the segregation in the grain boundary is more serious than the segregation in the grain both in air cooled ingot and quenching ingot, the composition in grain boundary are not uniform; the segregation of Fe is more serious than the segregation of Al and V; the composition in air cooled ingot and quenching ingot are more uniform than the composition in cast; the segregation in quenching ingot is lowest, quenching can reduce the segregation.

中文摘要：对热处理之后进行水冷与空冷的TB6合金铸锭进行了成分分析，对两种热处理所得结果进行分析，发现无论铸态还是空冷与水冷之后的试样，晶界偏析总比晶内严重，而且晶界处的成分分布很不均匀；Fe元素的偏析要比Al元素与V元素的偏析严重；空冷与水冷后的试样，各个元素分布较原始态的更加均匀，各测试点之间的差距减小；水冷之后的试样成分分布更理想，比空冷的效果好，水冷可以显著改善TB6合金铸锭偏析现象。

By optimizing such process as refining dreg series and deoxidizing,mode of adding slagging raw materials,blowing Ar system,preventing nitrogen adding in refining process,adopting such process measures as controlling degree of superheat of smelten steel strictly,selecting suitable pulling speed and colling water quantity,using electromagnetism stir in continuous casting,the center carbon segregation index is at about 1.04 basic...

通过对精炼工序中精炼渣系和脱氧工艺选择、造渣原料的加入方式、吹氩制度、防止增氮等工艺的优化，在连铸中采用严格控制钢水过热度、选用合适的拉速和冷却水量、使用电磁搅拌等工艺措施，中心碳偏析指数集中在1.04左右，夹杂物尺寸变小、数量大为减少，疏松和缩孔均降低到0.5级以下，线材面缩率达到34%以上，大部分为41%~44%，索氏体体积分数达到91%，可顺利拉拔至0.3 mm。

Aim at protecting moulding introduced by small square billet via columniform nozzle,therefore the condition was researched in this paper by means of simulation, which willhelp productivity with improving the casting speed.

针对目前小方坯普遍采用保护浇注，使用直筒型水口，模拟了这种情况下结晶器内的流场以及传热凝固现象，为高效方坯连铸提供理论依据。

SCR has coreless medium frequency induction melting furnace of the set of 3t.5t; to improve product quality, to overcome the common sand casting casting defects can not be avoided, an increase of large-scale horizontal centrifugal casting equipment, various types of cast iron with an annual output of 5000T cast steel, roll production capacity.

现拥有可控硅无芯中频感应熔炼炉3t.5t各一套；为提高产品质量，克服普通的砂型铸造无法避免的铸造缺陷，增加了大型卧式离心铸造设备，具备年产5000T各类铸铁铸钢、轧辊的生产能力。

Connection elbow s have been produced by an easy operation that horizontal cluster casting with core_up moulding technology has been adopted which consists of water glass and lime sand cured by CO2 for molding and coremaking with reasonably selected method while feeding through making the most of gating, hence all performance targets of products meeting desired technical requirements.

采用水玻璃石灰石砂CO_2硬化制型、芯，合理选择造型方法，采用组芯水平串铸工艺，充分利用浇道补缩铸件，生产操作方便，所获得的接线弯头性能等各项指标，均达到技术要求。

These segments are heat-cast, with the central core formed by insertion of a coring tool during the casting operation.

这些部分是热铸态，与中央的核心所形成的插入一个取心工具在铸造的运作。

Renewed shall be blade that was broken. The crownless again shall be king.

断折的圣剑将被重铸，无冕者将再度为王。

Packaging as human wisdom, a widely used in daily life, production, as early as 3000 BC. Egyptians began to use the manual method of casting, blowing the original glass bottle containing items for the same period. Egyptian paper Cyperaceous the pith of a primitive made of paper used for packaging items, 221, 105, Cai Lun invented Papermaking in China, showing the hand-made paper made labels.

摘 要：包装作为人类智慧的形成晶体，广泛用于糊口、出产中，早在公元前3000年，埃及人开始用手工要领熔化铸、吹制原始的玻璃瓶，用于盛装物品，统一期间，埃及人用纸莎草的心髓制成为了一种原始的纸张用以包装物品，公元前105年，蔡伦发现了造纸术，在中国出现了用手工造的纸做成标贴。

The split between the two groups can hardly be papered over.

这两个团体间的分歧难以掩饰。

This approach not only encourages a greater number of responses, but minimizes the likelihood of stale groupthink.

这种做法不仅鼓励了更多的反应，而且减少跟风的可能性。
