目前德国发明了在连铸机上用氧气切割板坯的新方法,并已获得专利。长期以来,氧气切割板坯一直未解决在切割区和切断后板坯的支撑问题。新发明通过在切割区采用对称设置的悬臂辊(用于支撑板坯)及其支撑架解决了这个问题。新发明设备的切割过程是:板坯以铸速行至切割区,通过机械作用使切割机与板坯同步运动,然后用接触式探测装置测定板坯的位置和宽度,接着开始切割作业。在切割时,悬臂辊与氧气烧嘴同步运动,由于悬臂辊仅支撑板坯的边部,所以可以进行纵向或
At present, Germany invented a new method of cutting slabs with oxygen on a continuous caster and has been patented. For a long time, the oxygen cutting slab has not solved the problem of supporting the slab in the cutting area and cutting. The new invention solves this problem by using symmetrically arranged cantilever rollers (for supporting the slab) and their support brackets in the cutting zone. The cutting process of the newly invented equipment is that the slab runs at a casting speed to the cutting zone, moves the cutter and the slab synchronously by a mechanical action, and then determines the position and the width of the slab by means of a contact type detector, and then starts the cutting operation. During cutting, the cantilever roller moves in synchrony with the oxygen burner. Since the cantilever roller supports only the edge of the slab, it is possible to perform longitudinal or
