为了解决热轧生产线上中间板坯头尾温差过大,以及受到场地限制的生产线、降低轧线的投资和提高产品质量等问题,可以通过热卷箱达到上述目的。热卷箱安装于粗轧机的延伸辊道和切头飞剪之间,将粗轧机轧制成的中间坯卷成热钢卷,然后通过其中的开卷机构将热钢卷的头部也就是粗轧机最后道次的尾部引入夹送辊进行压平矫直,这样可以使板坯的头部能够顺利地通过切头飞剪和精轧前的除鳞箱后送入到精轧机组。同时利用热卷箱也可
In order to solve the hot rolling production line in the middle of the slab head and tail temperature is too large, as well as subject to site restrictions on production lines, reduce rolling line investment and improve product quality and other issues, through the hot coil box to achieve the above objectives. The hot coil box is installed between the extension rollers of the roughing mill and the cutterhead shears. The intermediate bar rolled by the roughing mill is rolled into a hot coil, and then the head of the hot coil is also roughed through the unwinding mechanism therein The last pass of the rolling mill introduces a pinch roller at the tail of the rolling mill for flattening and straightening so that the head of the slab can be smoothly fed into the finishing rolling mill by means of shearing and shearing before cutting and finishing. Also use the hot coil box can be
