长沙东风钢厂70×70毫米的连续铸钢设备采用了如下二次冷却区辊道结构。其特点是采用无缝钢管1作为辊身,胶木(酚醛胶布)2作为轴承(见附图)。这种轴承以一定的过盈配合压入辊身两端加工过的内园里,再用一根小管子3(自来水管或无缝钢管都可以)做心轴,将辊道支承在机架4上。小管子一端用盖板焊死,中间部分钻有小孔5,另一端则焊上水管接头6,水管接头通过橡皮管接在一个总水管上。浇
Changsha Dongfeng Steel 70 × 70 mm continuous casting equipment used in the following cooling zone roller structure. Its characteristic is to use seamless steel pipe 1 as a roll body, bakelite (phenolic tape) 2 as a bearing (see photo). This bearing with a certain interference fit into the roller body at both ends of the processing of the inner garden, and then use a small tube 3 (water pipes or seamless steel tubes can) do the mandrel, the roller support in the rack 4 on. One end of the small tube welded to the lid, the middle part of the small holes drilled 5, the other end is welded on the water pipe joints 6, water pipe joints through a rubber pipe connected to a total water pipe.
