Tempering includes high temperature tempering, medium temperature tempering and low temperature tempering. Tempering means to reheat the RINA grade D stern frame steel quenched steel to a certain temperature and then cool it in a certain way. Tempering can reduce or eliminate the internal stress produced by quenching, reduce the hardness and strength, and improve the ductility or toughness of steel. After RINA grade D stern frame steel quenching, the workpiece should be tempered in time, and the required mechanical properties can be obtained through the combination of quenching and tempering.

In mid-October, news from Shanxi called for the elimination of more than 20 million tons of coke oven capacity below 4.3 meters before the end of the year. By the end of October, 12.3 million tons of production capacity had been eliminated, and in November, 10.52 million tons were expected to be eliminated. In the later period, localities will successively announce plans for reducing production capacity during the heating season this year, involving 29.73 million tons of coking capacity.
