当前,汽车制造正向轻量化和高强化发展。由于我国木材资源缺乏,以钢代木制造车箱已势在必行。16MnXt冷轧板就是利用我国富有稀土资源生产的适用于汽车制造上冲压成型和滚压成型部件的新型低合金冷轧钢板。从1981年开始,鞍钢与长春第一汽车制造厂合作,在原来生产16MnXt汽车用钢的基础上,改进了稀土加入方法,生产了1.2,1.5和2.0mm厚的冷轧钢板(带),由长春第一汽车制造厂试制载重汽车车箱 相似文献

作为超深冲用冷轧钢板,已研制出脱退火超低碳钢和添加 Tj(V、Zr、Nb)等形成碳氮化物的元素的钢。但是,这些钢有以下缺点:前一种钢晶粒粗化,冲压成型时,容易产生桔皮状缺陷;后一种钢表面清洁度较差。而且,在连续热镀锌线上不容易生产出深冲性和镀层良好的钢板。为了改善这些缺陷,日本川崎制铁所已研制出用加 Nb 的超低碳铝镇静钢生产超 相似文献

Surface Ferrite Grain Refinement and Mechanical Properties of Low Carbon Steel Plates 总被引:1,自引:0,他引:1
Considering the specialities of the steel plate production, the TMCP study has been carried out with Gleeble 2000 tester to explore the possibility of fine grained ferrite in the low carbon steel plates with the chemical composition of C 0.13--0.18, Si 0.12-0.18, Mn 0.50-0. 65, P 0. 010-0. 025, and S 0. 005-0. 028. The plates with thickness of 8. 7 mm in which the ferrite grain size is smaller than 8μm have been produced by special de- formation process in the laboratory. Furthermore, the trial production of special plain carbon steel plates of 16-25 mm in thickness and 2 000- 2 800 mm in width with fine grained ferrite has been successfully carried out in the Shougang Steel Plate Rolling Plant. The ferrite grain size is 5.5-7μm in the surface layers and 9.5-15μm in the central layer respectively. The yield strength is 320- 360 MPa, tensile strength is 440-520 MPa and the elongation is 25%- 34 %. It is very important for the rolling plants to improve the low carbon steel plates' mechanical properties. The results show that the ferrite grains in the surface layer can be refined effectively by the appropriate rolling process, and the strength can be also increased. 相似文献

The Magnitogorsk Metallurgical Combine has mastered the production of galvanized cold-rolled automobile sheet from high-strength
IF-type steel with an ultralow carbon content. The steel also has superior stampability. The article describes a technology
that the oxygen-converter shop of the MMK is using for the production and out-of-furnace treatment of IF-steel of the required
chemical composition. The article touches on several of the factors that help reduce production costs and improve the service
properties of cold-rolled sheet obtained from the steel.

The production of dual-phase ferritic-martensitic steel in the hot-rolled and hot-galvanized states is considered, as well as the production of cold-rolled steel microalloyed with phosphorus (≤0.12% P), which is characterized by increased resistance to residual denting. The mechanical properties of trial industrial batches for auto parts are outlined. 相似文献
