在加热时间（s）＝kd，d为工件的厚度，mm，k为系数，和出厂数据。（3）冷却。不同的冷却系统用于不同的组织。它通常在静态空气中冷却。如果工件很大，可以通过吹风或雾来冷却。长度一般为5～8m或4～7m，主要由热轧碳结构和ST65组成。进口规格直径小，305mm，大规格7813mm。7.3。小口径薄壁无缝钢管，如183mm、223 mm、23.93mm等，分别从法国、西班牙进口。
It can be said that, to a certain extent, this is because of excessive interference and other local power from the private interest, the steel industry not only delayed the transfer to the upstream of the industrial chain to achieve the goal, but also made the T overcapacity problem of the steel industry more and more serious. In this regard, the problem of overcapacity in the steel industry has not been alleviated. In essence, it should be a question of the relationship between power and market, whether the market should play a decisive role or not.
