南京建业鋼铁厂用很小的轧机轧钢錠成功,解决了开坯机缺乏的困难。该厂职工利用厂内一套旧的190mm(三輥式、五机架)小軋机,直接用4吋(115mm)鋼錠开坯并軋成鋼材,解决了长期以来因不能开坯而引起的停工待料的威胁。他們采取了以下一些措施: 1.加固机架:原有的旧机架过于单溥,强度太小,因此新换了机架,新机架的各部分都加厚,特別是加大加重了底部。新机架比老机架的重量約增加40％;底脚板的形状也作了修改,将原来的平板改为凸形板,使机架安装后更加平稳坚固。 2.增加动力:将原来的60瓩马达换成130瓩馬达,并在皮带上增加了一个飞轮,保証了开坯需要的动力。
Nanjing Jianye Iron and Steel Mill with a small rolling mill ingot success, to solve the lack of open machine difficulties. The plant workers used the old 190mm (three-roll, five-stand) mill in the mill to directly billet and roll steel into 4-inch (115mm) ingots to solve the long-term Suspension of work threat. They take the following measures: 1. Reinforcing the rack: the original old rack is too small, the intensity is too small, so the new rack has been replaced, and the parts of the new rack are thickened, especially the heavier bottom. The new rack weighs about 40% more than the old rack; the shape of the footboard has also been modified, changing the original plate to a convex plate to make the rack more stable and solid after it is installed. 2. Increase the power: the original 60 瓩 motor replaced 130 瓩 motor, and added a flywheel in the belt, to ensure the power needed to open the blank.
