现在,世界钢产量中有很大一部分用连铸机一次浇铸成板坯和方坯、这比起先铸锭,后开坯的传统方法,可节约大量的金属.连铸机可分成几个不同的区段,每一区段都有许多尺寸相同的辊子.在大多数连铸机中,这些辊子都是实心锻件或用空心棒材经机械加工制作.这些辊子最初使 Now, a significant portion of the world’s steel production is cast into slabs and billets once by a caster, which saves a lot of metal compared to the traditional method of casting ingots and postbaking. The caster can be divided into several different , Each of which has many rollers of the same size, and in most caster these rollers are either solid forgings or machined from hollow bars.These rollers are initially
