On the other hand, some steel varieties such as hot-rolled coil etc itself is not big, rise early rising in the technology has the necessary.
另一方面，部分钢材品种如热轧卷等本身前期涨幅并不大，技术上有上涨的必要。
It represents the trial manufacture of grade X80 pipelines steel hot rolled coil with characteristic of acicular ferrite at BaoSteel Mill.
简要介绍了宝钢试制的以针状铁素体组织为特征的X80级管线钢热轧板卷。
After the hot-rolled steel coil plant sent, the first after three consecutive treatment, the first use hydrochloric acid to remove oxide film, and then to be cold-rolled unit.
经过热轧厂送来的钢卷，先要经过连续三次技术处理，先要用盐酸除去氧化膜，然后才能送到冷轧机组。
Hot-rolled steel coil and the product is divided into two ingots-plate, hot-rolled through the rails after a few millimetres in thickness, if a user requests plate thinner, but also a cold-rolled.
热轧成品分为钢卷和锭式板两种，经过热轧后的钢轨厚度一般在几个毫米，如果用户要求钢板更薄的话，还要经过冷轧。
