The "Plan" pointed out that by the end of December 2020, the steel production capacity in Tianjin will be controlled at about 15 million tons, and the steel production capacity in Hebei Province will be controlled within 200 million tons, and the elimination of the carbonization chamber with long furnace age and poor furnace condition will be accelerated. 4.3 Rice coke ovens promote the gradual withdrawal of independent coking companies. At present, there are 24 steel enterprises in Shanxi Province in need of transformation, of which 17 have been completed, and the remaining 7 enterprises are speeding up project-related finishing work.

The hot rolling method is to heat the S690QL vs S690QL1 steel material to about 1000 ℃ ~ 1250 ℃ and use the rolling mill to roll it. The traditional hot rolling process is generally divided into the following two steps: the first step is to use the primary rolling mill or billet rolling mill to roll the ingot, billet or continuous casting billet into a certain shape and size of billet. This kind of S690QL vs S690QL1 rolling process is usually called semi-finished product production, also called blank production.
