Perhaps it is for this reason that in the past quite a long time, on the other hand, despite many warnings from the parties concerned, the excess capacity of the steel industry, and even industrial restructuring, the local government still avoided the iron and ST through the "zero" policy response is the eel project; at the same time, in order to safeguard the economy. Protecting the contribution of related steel production capacity to local GDP, some places have spared no effort to support local backward production projects even if they clearly know that steel production in some places is significantly backward and policies are biased.山东大鼎钢管厂、山东大鼎金属材料有限公司
It can be said that, to a certain extent, this is because of excessive interference and other local power from the private and more serious. In this regard, the problem of overcapacity in 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.
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
