3.6.2 拉坯机水平连铸机有两种结构方式,即辊式拉坯机和夹板式拉坯机。而辊式拉坯机又有牌坊式和悬臂式之分。牌坊式的辊式拉坯机采用单辊驱动方式。下辊为主动辊,其位置不变,而上辊依靠液压缸将铸坯压紧在上下辊之间。美国铸钢工程公司的悬臂式拉坯机,上下辊的配置基本上也是这种结构,如图14所示。原联邦德国铸造工艺公司的悬臂式拉坯机为开式焊接结构。拉坯辊为悬臂式安装,利用油缸通过铰轴使上辊上、下移动。工作
3.6.2 caster Horizontal caster has two kinds of structural methods, namely the roll caster and plywood-type caster. The roll-casting machine has another arch and cantilever points. Arch-style roll-drawing machine with a single roller drive. The lower roller is a driving roller whose position is unchanged, and the upper roller presses the slab against the upper and lower rollers by means of a hydraulic cylinder. US Cast Steel Engineering Company cantilevered drawing machine, the upper and lower roller configuration is basically this structure, as shown in Figure 14. The original federal German casting company’s cantilevered casting machine for the open welding structure. Pull roller cantilever installation, the use of oil cylinder through the hinge shaft so that the upper roller, the next move. jobs
