自回火温度对20MnSi钢筋组织及力学性能影响 总被引:1,自引:0,他引:1
对不同合金成分20MnSi钢进行控轧控冷和不同温度自回火处理后,分别采用光学显微镜和多功能材料试验机研究了不同自回火温度下不同硅、锰含量20MnSi钢筋的显微组织及力学性能。试验结果表明:随着自回火温度的升高,钢筋的表层显微组织逐渐得到改善,并最终得到珠光体组织,使20MnSi钢筋的强度与韧性得到良好配合; 20MnSi钢筋的淬透性随钢筋中Si、Mn元素含量的提高而提高,从而显著增强钢筋的力学性能。采用控轧控冷工艺,在标准范围内适当提高硅、锰含量,并在轧后进行高温自回火,可在不额外加入Nb、V等微合金元素的基础上进行HRB400钢筋的生产。 相似文献

Slag chemistry applied in the AlloyStream process differs from that used in the production of high carbon ferromanganese in the submerged arc furnace. In process development of the AlloyStream process, several pilot plant and demonstration plant campaigns were completed. Slag samples were selected from the samples collected at each tap, throughout the four month pilot plant campaign. Phase characterization of these samples is reported here, and the results are interpreted in terms of the slag chemistry operational options in the AlloyStream process. 相似文献

In regard of the reduction of energy consumption during the production of steel slabs and strips different charging procedures are of high economic interest. Especially hot and direct charging procedures are used in modern ways of strip production like CSP and strip casting. For simulation of these procedures and their related effects on the microstructure and the mechanical properties of the material, the complete process chain of melting, casting and hot rolling in one heat has been realised in a pilot scale. In this concept process parameters such as temperature over time are controlled during the complete process. By variation of the thermomechanical process parameters the microstructure and the mechanical properties gained in different processing routes can effectively be simulated. This new set‐up allows the simulation of the casting and rolling processes not only in a laboratory scale by using conventional compression, tensile and quench tests but now also in a pilot scale. The results will be used as input parameters for FEM simulation. In this paper the set‐up of the laboratory facility is described with the measured and controlled parameters. 相似文献
