连铸机结晶器下面的铸坯,具有高温和凝固壳较薄的特点,因此它要求支承和导引装置具有牢固和耐热性好的性能。目前,连铸机结晶器下面铸坯的支承机构主要有以下三种方式: (1)辊子支承式;(2)冷却格栅或冷却板支承式;(3)上述两种方式的组合结构式。日本住友重机公司的板坯连铸机,大多采用了防止铸坯鼓肚、减少漏钢的冷却格栅支承方式。该公司对原来使用的冷却格栅进行了多次研究,最近研制成功了一种新的组合式(或叫
The billet below the caster mold, which has the characteristics of high temperature and thinned solidified shell, requires that the support and guide have strong and heat-resistant properties. Currently, there are three main ways to support slab under the continuous casting mold: (1) roller support; (2) cooling grille or cooling plate support; and (3) combination structure of the above two methods. Sumitomo Heavy Industries, Japan slab caster, mostly used to prevent the slab cast belly, reduce the cooling grid cooling support. The company conducted several studies of the original cooling grille, and recently developed a new combined (or called
