双辊薄带连铸实验钢种的产业化问题 总被引:1,自引:0,他引:1
本文主要对双辊薄带坯连铸实验钢种的产业化问题进行了讨论。认为用1Cr18Ni9和2Cr13、PH15-7Mo连铸薄带坯生产出的冷轧带钢质量可达到国家有关标准,但要实现产业化还有些问题需要解决。高钼奥氏体不锈钢(6^Mo)适于双辊薄带坯连铸,硅钢和高速钢则还不能作道先产业化的考虑。 相似文献

Metallurgical features of the twin‐roll strip casting process are discussed. The as‐cast structure of two austenitic stainless steels is evaluated using EPMA and metallography. Cleanness levels as reached in twin‐roll strip casting are compared with conventional and thin slab casting. In‐line annealing is described as a method for grain refinement. The scale layer on twin‐roll cast strip is characterised for low carbon and stainless steels. 相似文献

This article is try to explain or analyze the key technologies of controlling the surface quality of low carbon steel as cast strip through investigation of interface heat transfer between solidified shell and liquid steel.The one of the key technologies of controlling surface quality of low carbon steel as cast strip is through the casting roll surface texture in order to achieve the homogeneous solidification on the casting roll.Another is through forming a thin film on the casting roll surface in order to achieve a balance between rapid solidification and homogeneous solidification.This film formed between the twin roll and the molten steel can be controlled by adjusting the chemical composition and inclusion in liquid steel through controlling the amount of all[O]and free[O]. 相似文献

特种合金双辊薄带连铸生产技术进展 总被引:1,自引:0,他引:1
双辊薄带连铸技术(TRC)已发展到产业化的初级阶段,如日本新日铁、德国Eurostrip、美国Castrip、韩国Postrip等公司的薄带连铸生产能力已达30~50万t/a,多炉连浇时间超过10h。介绍了多种特种合金,如髙硅电工钢(w(Si)为4.5%~6.5%)、高速钢、Invar合金、Inconel合金、TWIP钢等可用双辊薄带连铸,一次性形成毫米级薄带。由于高速冷凝,晶粒细化,成分偏析极少,生产成本低,成材率高,TRC是当前双辊薄带连铸产业化的新途径之一。 相似文献

AbstractAn unequal diameter (1 : 3), two roll thin strip casting machine has been designed and fabricated for investigation of the direct casting of thin strip on a laboratory scale. The system consists of a preheatable shallow tundish with online heating facility, water cooled rotating rolls (chill and auxiliary) for solidification of the liquid metal, and a stripper assembly. The machine has a variable speed. Roll gap setting and roll pressure adjustment are two important features of the machine. It is also possible to vary the placement angle of the auxiliary roll with respect to the chill roll. A heat transfer model was developed, based on experimental casting results. Experiments were conducted using AISI 304 grade stainless steel. Up to 100 kg of steel was cast without interruption into strips of widths 100 and 200 mm and thickness varying between 1 and 2 mm. Some of the process parameters affecting the quality of the strip were identified. 相似文献
