近几年来的生产实践证明,在“土洋结合”的φ76毫米无缝钢管机组上,不但能生产出优质碳素钢和低合金结构钢钢管,而且能生产出符合高要求的不锈、耐酸和耐热钢管。本文仅就我厂生产铁素体型高铬耐酸钢管的生产工艺做一个简要的介绍。一、设备及管坯的准备我厂生产Cr17铁素体型耐酸钢管采用了斜底式连续管坯加热炉,辊式穿孔机,自动轧管机,20吨和15吨双链冷拔机等设备。管坯的准备工作如下:
In recent years, production practice has proved that in the “combination of soil and sea” φ76 mm seamless steel tube unit, not only to produce high-quality carbon steel and low alloy steel pipe, and can produce high-demand stainless steel, acid And heat-resistant steel pipe. This article only on my factory production of ferrite high-chromium acid steel pipe production process to make a brief introduction. First, the preparation of equipment and tube I plant the production of Cr17 ferrite type acid-resistant steel tube with a continuous inclined tube furnace, roller piercing machine, automatic pipe rolling machine, 20 tons and 15 tons double-strand drawing machine and other equipment . The preparation of the tube is as follows:
