一、研制的背景 最近,在钢铁工业中,为了节能将高温状态下的连铸板坯直接装入钢坯加热炉,这便是正在盛行的温坯装入。比这更进一步,将连铸热坯在热状态直接送至轧机轧制的热坯直接轧制技术(直送轧制)也在实际应用上作了一些尝试。这样,在进行热坯温坯装入时,从保证钢坯质量和连铸工厂操作 First, the development background Recently, in the steel industry, in order to energy-saving high-temperature state of the continuous casting slab directly into the billet furnace, which is the prevailing warm billet loading. To go a step further, some attempts have been made to apply the continuous casting billet direct hot rolling technology (direct rolling) in the hot state to the mill rolling. In this way, when the hot billet is loaded, the billet quality and the continuous casting plant operation are guaranteed
