为了阐述双辊浇铸过程中凝固组织的形成情况，通过实验室规模的双辊铸机进行了浇铸SUS304奥氏体不锈钢钢带的试验。在浇铸过程中出现两种凝固组织：住状枝晶和等轴晶。随着银子和钢水接触时间的增加，技品区的厚度增加，而等轴区的厚度几乎保持不变。随着初始辊隙的增加，等轴 In order to illustrate the formation of solidified structure during the twin-roll casting process, the cast SUS304 austenitic stainless steel strip was tested by laboratory-scale twin-roll caster. Two types of solidified structures appear during casting: live dendrites and equiaxed grains. As the contact time between silver and molten steel increases, the thickness of the technical area increases, while the thickness of the equiaxed area remains almost unchanged. As the initial nip increases, equiaxed
