Cold rolled non decarbonization cold rolled strip was annealed under protective atmosphere. The protective atmosphere consists of a single inert gas, argon or helium, but also includes mixed gases. By adjusting the composition of these mixed gases, the speed of redox, decarbonization and Carburization in the annealing process of strip steel is equal, so as to realize the non-oxidation and non-decarbonization annealing of strip steel. After annealing, bright precision tubes should be decarburization. The annealing factor of the bright tube depends on the atmosphere and redox reaction. And other inert gases are neutral protective atmospheres of steel. It is widely used, but the oxygen atmosphere must be removed to play a good protective role. Commonly used mixed protective atmospheres.结构用无缝钢管(GB/T8162-2008)是用于一般结构和机械结构的无缝钢管。流体输送用无缝钢管(GB/T8163-2008)是用于输送水、油、气等流体的一般无缝钢管。内外涂塑复合钢管是以焊接钢管为基材 可在受污染的海水光亮精密管退火可保持光亮管的外观精度,尺寸精度高,越来越受到客户的青睐。

Following the decline in crude steel production in the first ten days of this month, crude steel production rose again in the first ten days of this month. Inventories of heat preservation and anticorrosion pipe manufacturers and factories also declined. The production situation of secondary or steel plants is not clear. At present, as raw material prices continue to fall, consumer enterprises still have profit margins; coupled with financial pressure, most steel mills need to maintain operation in order to continue to obtain savings; therefore, steel mills still adhere to a higher start-up rate; Anshan region, for example, as of this month, Tangshan blast furnace start-up rate is about.0%, high production capacity application rate. Up to.0%, the rate of increase was normal.山东大鼎钢管厂、山东大鼎金属材料有限公司
