Reducing costs and increasing efficiency is not only an expedient solution to the industry's winter, but also a long-term strategy to enhance the core competitiveness of enterprises. Xinda's majority of cadres and workers firmly establish the responsibility of "responsibility in me, the courage to bear" and the crisis awareness of "hard days, tight days", recognize the situation, change the concept, with the courage to the blade, actively respond to risks and challenges. Consciously breathe with the company, share the fate, and effectively achieve the unity of thought and action to reduce costs and increase efficiency, gather the power of the masses of "do everything possible to reduce costs and increase benefits", and reduce costs and increase efficiency work to the extreme.

In order to improve the quality of downstream products and continuously enhance the competitiveness of the industry, Hebei Xinda Iron and Steel Group Co., Ltd. set up an improvement group. Li Shulin, the leader of the factory, led all the members of the group to carry out an analysis discussion. And through sampling test, field investigation, cutting Angle test, temperature measurement and other methods to verify the end factors, easy to find the main reason, improve the quality of the board.

After finding the crux, the research team immediately developed problem-oriented measures, and each measure was designated to be responsible for, inspected, and regularly analyzed and summarized the implementation of various measures, so as to ensure that the measures were implemented.

To solve the problem of large ladle edge, the ladle edge is hooded by the ladle repair gap to prevent the ladle edge from melting into the molten steel, resulting in component burning damage, such as the ladle edge falling into the ladle, timely notify scheduling and continuous casting speed reduction, and fold the ladle edge out; If there is no folding condition after the ladle edge falls into the ladle, the composition of the molten steel shall be capped, and more deoxidizer shall be added appropriately to ensure that the molten steel is qualified, and the thermal test shall be carried out.

In view of the problems of low baking temperature and high moisture in the new ladle, clean the ladle before baking to prevent debris from entering the ladle, perform oxygen-enriched baking 3 hours before starting the ladle, and bake the ladle temperature to more than 900℃, so that the water vapor in the ladle dry material and gas can be effectively discharged, and the upper limit of heat exchange or pouring furnace components can be reached to reduce the start-up bubbles.

In view of the problem of high moisture of the new ladle, the improvement team improved the on-line system of the new ladle, so that the baking temperature was above 500℃, the first supply of 2 stages, smelted Q235 steel grade, and did not smelt low-composition Q195D steel grade; Make abnormal ladle transfer cards, track and supervise the use of various special ladles, prevent the increase of molten steel gas content due to the moisture of new ladles and the low temperature of special ladles and the burning of holes, and establish an AC group and a quality feedback group, requiring the converter furnace leader to feedback the constant oxygen photos of each steel, and the continuous casting machine chief to feedback the photos of the middling slag discharge, so as to strengthen the process control of the production process.

Through the joint efforts of the team members, the project successfully solved the problem of edge cracking of downstream products, and in the month of improvement, the proportion of edge cracking was only 0.03%, far lower than 0.1% of the surrounding excellent enterprises, improving product quality and market competitiveness, and effectively enhancing brand reputation.

A drop of water makes a river, a grain of rice makes a basket. Reduce costs and increase efficiency, focus on details, you are important in persistence. To carry out the work of "ultimate cost reduction" for all staff is to lead all staff with a sense of urgency to wait for time and strive to explore effective ways to reduce costs and increase efficiency. All units must be fully aware of the importance of this activity, with a high sense of responsibility and mission, into the battle of survival and development, guide employees to establish "every penny of savings may be transformed into a competitive advantage of Xinda, every cost reduction behavior is to contribute to the development of Xinda" cost reduction thinking, and strive to achieve the goal of cost reduction. Promote high-quality development!
