对昆钢而言，该技术的应用，首先可以经济有效地实现现有采选技术及高炉冶炼所不能完成的高磷铁矿石的利用，大幅度降低在钢铁生产中占绝大比例的原料成本，缓解国际国内生产原料紧张而造成的成本压力，为昆钢创造巨大的经济效益；其次可以促进昆钢产品的升级换代特别是高附加值超低磷、超低硫钢种的开发，增强昆钢的市场适应能力和效益创造能力；再次可促进高炉及转炉技术经济指标的改善，降低生产成本，且利于转炉生产实现高效吹炼和少渣冶炼；此外，该工艺能显著提高冶炼环节的平稳顺行及高温、高质量铸坯生产的可控程度，可实现高效连铸和连铸连轧生产，提高昆钢生产的集约化程度；最后，该工艺能实现冶炼功能的分工和生产流程的优化，可提高昆钢炼钢与连铸生产的计算机自动控制程度，有效促进炼钢—连铸—轧钢的工艺、设备、生产组织和管理、物流管理、生产操作等环节的一体化管理的实现。

The results show that the equiaxed zone ratio of the casting billet is greatly increased,with its soidification structure is obviously improved,and the momentum values of the electromagnetic forces both parallel to and perpendicular to the direction of the traveling magnetic field pulsate periodically with time.

采用三相通入不同电流的非平衡线性电磁搅拌技术进行了铸坯的静态浇铸实验，并对电磁搅拌过程中钢液内的电磁力各分量的瞬时值进行了理论分析·结果表明，当采用将电磁搅拌器的三相通入不同电流的非平衡线性电磁搅拌时，在钢液内所产生的电磁力是脉动的，其大小呈周期性变化，尤其是垂直于磁场运动方向上的电磁力，其脉动的幅度很大·由此认为，当采用将搅拌器的三相通入不同电流的非平衡线性电磁搅拌时，所产生的垂直于磁场运动方向上的脉动电磁力是提高等轴晶比率，改善铸坯凝固组织的一个重要原

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。

The microsturcture characteristics of M2 cast-strip were studied with such experimental methods as metallographic analysis, SEM, XRD and TEM[0]. The effect of sub-rapid solidification on the size, type and distribution of eutectic carbides in M2 cast-strip was analyzed. The effect of heat treatment temperature and its holding time on the eutectic carbides in M2 cast-strip was explored. The eveolution of metastable phase of M2C eutectic carbide during the heat treatment period and the decomposition dynamics concerned were researched. The M2 cast-strips were rolled into thin strips and the effect of deformation ratio on carbides in M2 cast-strip was examined. Then these thin strips were comparied with those that were produced by conventional technology on carbide, hardness, red-hardness and bend strength. At last the rolled M2 cast-strips were made into saw blades and their cutting performance was experimented on in tools factories and then compared with that of similar products produced by conventional technology.
