用 Gleeble-1500型热力模拟试验机研究了含钛高强度钢变形奥氏体在连续冷却过程中的相变规律，用膨胀法结合金相法建立了该钢变形和未变形奥氏体的连续冷却转变曲线，并探讨了该钢的热轧可行性。

In alloy steels the kind and amount of alloying element influences only the hardenability (the ability of the workpiece to be hardened to depths) of the steel and does not affect the hardness except in unhardened or partially hardened steels.

除了非淬硬钢或部分淬硬钢外，合金钢中合金元素的种类及含量仅影响钢的淬透性(工件被硬化到深层的能力)而不影响硬度。

Current density vector, joule heat and Lorentz force were mainly localized in region where the velocity of steel flow was high; joule heat produced by induce current has limited influence on steel flow, could be ignored.

结果表明：电磁力、电流密度矢量、焦耳热主要分布在钢液速度较大区域，电磁力明显改变了结晶器内钢液流场，感应电流产生的焦耳热对钢液温度场影响很有限，可忽略。

Statistic analysis to the mechanism and failure of bleed out caused by broken corner is made, and the result shows that the main reason of bleed out caused by broken corner is the inhomogeneity of the shell of crystallization and the inhomogeneity of the secondary cooling system which are caused by the processing parameter in the inside of copper pipe and the wear-out in the corner during the service.

对角裂漏钢机理及现场角裂漏钢事故进行统计分析，认为造成角裂漏钢的主要原因是铜管内腔的工艺参数及使用过程的角部磨损造成的出结晶器坯壳不均匀和二冷系统冷却的不均匀性。

The joint components can be determined directly based on the axile forces and diameters of each bars given by the finite element analysis, and reduplicative checking computations can be avoided by the method.

同时 ，网格结构节点数量众多，节点用钢量占杆件用钢量的 1 /5～ 1 /4，合理设计节点对结构安全度、制作安装、工程进度、用钢量指标以及工程造价都有直接影响。

It was showed that open circuit potential of A3 steel shifted negatively, corrosion rate increased when Cladosporium activity was great.

结果表明，当枝孢霉菌活性较大时，其代谢产物改变了溶液的组成，A3钢开路电位负移，腐蚀速率加大，促进了A3钢的腐蚀；当枝孢霉菌活性较小时，A3钢的腐蚀也减缓。

The new venture offers a complete procurement service to their cliental for the design and manufacturing of structural steel work which is utilized in the commercial and industry building construction market.

M/s. The following dimensionless relationships were obtained: Sh=2+0.073Re〓Sc〓〓〓 The desulphurization process by powder injection and blowing in RH refining of molten steel and its mechanism have been considered and analyzed. Based on the tworesistance mass transfer theory and the mass balance of sulphur in the system, a kinetic model for the process has been developed. The related parameters of the model have been reasonably determined. Modeling and calculations for the process by injecting and blowing the lime based powder flux under the assumed operating modes in a RH degasser of 300t capacity have been carried out using the model.
