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.
Oil quenching causes surface deterioration easily. Due to the high surface activity, significant thin layer carburization can occur under the action of short and high temperature oil film. In addition, the adhesion of carbon black and oil on the surface is not conducive to simplifying the heat treatment process. The development of vacuum quenching technology mainly lies in the development of single gas cooled quenching furnace with excellent performance. Double chamber furnace can also be used for gas quenching (front chamber air jet cooling), but the operation of the two stations makes it difficult to load a large number of furnace, and easy to cause workpiece deformation or change the direction of workpiece quenching. NG deformation during high temperature movement.
