中板轧制中二次除鳞降压供水实践

本文主要介绍高压水通过适当缩小的管道及控制阀组成的系统，作为中板轧制中的二次降鳞，对解决热轧钢板表面的铁皮压入而进行的首次成功尝试。文中分别对坟管道及控制阀组成系统的工作原理、管道的选用、验算作一介绍。

Practice of Pressurer-reducing Water Supply for Secondary Descaling During Rolling of Medium Plate

This article mainly describes secondary descaling during rolling of medium plate using high pressure water through a system consisting of properly reduced pipe and control valves first successful trial in solving rolled in scale on hot-rolled plate surface. The article respectively describes the operating principle of a system consisting of high pressure pipe and control valves choice and test of pipe.
