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
