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.
太原无缝钢管(集团)有限公司董事长李晓波认为,“带钢”产能属于非法和非法产能,扰乱市场,污染环境,带来隐患。因此,在我国无缝钢管行业从增量发展进入减产阶段时,解决产能过剩问题,禁止“地板钢筋”势在必行。这既是一场“艰苦的战斗”,又是一场“持久战”。

Affected by the financial crisis and economic recession, the United States has frequently used trade remedy measures since 2009. A new study by Chad of trade restrictions imposed globally in 2009, such as countervailing, anti-dumping and special protection, increased by 29.5% compared with 2008. Trade protectionism measures have become an important hidden trouble affecting the world economic recovery.
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.
