连铸机结晶器下面的铸坯呈高温带薄壳的半熔融状态,要求支承铸坯的引导装置具有耐热性好及牢固的支承能力。 目前,连铸机结晶器下面的铸坯支承方式主要有三种: 1.辊子支承法; 2.冷却格栅或冷却板支承法; 3.上述两种方法综合并用。 日本住友重型机械工业公司的板坯连铸机,大多采用能压小铸坯凸度,减少跑钢的冷却格栅形式。 该公司对原来使用的冷却格栅结
The slab beneath the mold of the continuous casting machine is in a semi-molten state with high temperature and a thin shell, and the guide device supporting the slab is required to have good heat resistance and strong supporting ability. At present, there are mainly three kinds of slab support ways under the mold of continuous casting machine: 1. Roller support method; 2. Cooling grille or cooling plate support method; 3. The above two methods are combined and used together. Sumitomo Heavy Industries, Japan’s slab caster, mostly used to suppress the slab crown, reduce the running of the cooling grille form. The company used the original cooling grid junction
