Bao steel hot rolled sheets
At the last second on June 30, the last roll of steel weighing was completed in the 1780 production line of the hot rolling plant, and the production report showed that the 1780 production line of the hot rolling plant had a cumulative output of 17465 rolls in June, with a output of 38,0064.5 tons.
This is the 1780 production line after the completion of 373,500 tons of production record in May after another breakthrough! Again and again, the breakthrough perfectly reflects the “9·28” spiritual connotation of “nothing is impossible”, in the beginning of red July, hot rolling people with hot passion for the “102nd anniversary of the founding of the Party” handed over an excellent answer.
In June, Bao steel entered the high temperature weather, and the hot rolling site also entered the hot state. In order to complete the production tasks issued by the company, the factory department organized a seminar on the topic, requiring all departments to unify their thinking and concentrate their efforts to ensure the site. Among them, the rolling rhythm target is listed in the steel specification in the production technology room, which is displayed in the rolling line operation screen, and the struggle goal is clearly defined for the field operators, and the number of hours is continuously improved and broken through (compared with the increase of 1.6 blocks /h in May). Rolling area requires careful operation of the post, strictly adhere to the operation of the red line, starting from the heating furnace, to ensure the uniform temperature of each steel; Rolling line staff around the factors affecting the quality have suggestions, as far as possible to ensure the quality of each roll qualified; In addition, the stability of thin gauge rolling is improved synchronically, which makes the operator dare to speed up the rolling rhythm when rolling thin gauge, and the number of rolling breaks, rolling wrinkles and tail dumping in June is reduced by 40.3% compared with May. The equipment management office put forward the concept of “first time treatment” to ensure the rapid processing and recovery of on-site problems, and the unplanned downtime and total downtime showed a downward trend in June, and the calendar operation rate increased by 0.6%.
Hard times are hard to forget. Looking back on June, we can not forget the June8-11 rolling line of continuous scrap, can not forget the hot scene between the servo processing period, can not forget the technical problems of the night… We hot mill is like this, step by step survived, walked out of a new road, everyone saw the new peak of “400,000 tons”.
Focusing on the course of June, there are still some shortcomings, such as scrap steel and abnormal roll change too much. Now standing in the beginning of July, I believe that with the strong support of the company and the coordination of various functional departments, the hot rolling mill will create another new peak.
