In Hebei Rongxin Steel Co., Ltd. steel mill fire roar, a young figure has always stood tall as loose. His eyes like a torch, walking sonorous, more than ten years as a day with 1600℃ molten steel partner, with ingenuity and blood to interpret the "iron warrior" play.
He is the head of the smelting section, is the model worker Gao Yang, is a technology as a blade, responsibility as a shield, in the fire to temper the excellent steelmaker. In steelmaking production, quality, economic and technical indicators, furnace life research and innovation optimization and other aspects of a number of historical best indicators, participate in the preparation of new steelmaking projects, test and successful production, and achieve a number of technological breakthroughs and innovations.
Dare to challenge, promote the index breakthrough
As the core department of steelmaking, the production index of smelting section directly affects the benefit of the whole steelmaking plant. Gao Yang is well aware of this, and he leads the team to carry out in-depth exploration and innovation in all aspects, and is committed to reducing production costs and improving production efficiency.
In terms of steel consumption, Gaoyang has adopted a series of effective measures. He focused on controlling all kinds of spatter, optimized the parameters of the oxygen gun, standardized the gun position and fabric operation. Through continuous adjustment and improvement, the control precision of the end point double hit is improved. Steel consumption was successfully reduced to 1053.05kg/t steel, reaching the best level in history.
In terms of solvent consumption, Gaoyang organized a team to continue to carry out technical research, standardize the converter slag splashing operation on the basis of less slag smelting, and improve the slag splashing furnace protection effect. After unremitting efforts, the solvent material consumption is only 31.19kg/t, setting the best result since the establishment of the factory. At the same time, the service life of the converter has also been significantly improved, reducing the cost of equipment maintenance and replacement, and improving production continuity.
In terms of alloy consumption, Gao Yang takes stable end point control as the premise, standardizes slag retaining operation and steel outlet maintenance, and strictly controls the composition of molten steel within a very narrow range. The single consumption of ordinary carbon steel alloy is controlled within 6kg/t, achieving the best level in history.
Innovation and optimization, escort safe production
Safety production is the cornerstone of enterprise development, and Gaoyang always puts it in the first place. He actively promotes a series of safety innovation initiatives to create a safer and more productive work environment for employees.
In view of the problem of cleaning up the slag deposit under the furnace, Gaoyang put forward the transformation scheme of installing big shovel on the steel car and slag car under the furnace. Through this transformation, the production auxiliary time is greatly shortened, the average daily slag cleaning time is saved 200 minutes, and the safety hazards of personnel and vehicles entering the furnace are effectively eliminated.
In the converter blowing oxygen supply system, Gaoyang has also made bold adjustments. He shortened the oxygen supply time of half oxygen for dry dust removal and added oxygen step Settings. According to the characteristics of different blowing modes, combined with the concentration curve of oxygen and carbon monoxide, the oxygen supply can be set scientifically and reasonably. This measure not only ensures the safety of the electric field, but also reduces the average oxygen supply time of each furnace by about 1 minute, greatly improving the smelting efficiency.
In addition, Gaoyang also implemented a one-key slag blocking operation. By installing the limit in each action link of slag stopper, using PLC program control, the operation standardization of slag stopper is realized. Employees only need to operate the slag blocking equipment by wireless remote control, which can completely eliminate the safety risks in the steel process, and also reduce the dependence on personnel stability in the key operation links.
The optimization of parameters of oxygen gun nozzle is also an important measure of Gaoyang in safety production. After continuous testing and improvement, the spatter rate is reduced to less than 10%, the iron oxide content in the slag is reduced to 13%, which reduces the corrosion of the iron oxide in the slag to the lining and prolonging the service life of the lining.
Pursue the ultimate, cast a lean model
Gaoyang actively responds to the company's lean management philosophy and is committed to creating a fully functional and clean production site. In strict accordance with the on-site lean management standards, he carefully planned and constructed the functional station room, operation platform, safe green passage and visiting corridor. Under his leadership, the equipment and facilities are polished, the signs are clear and visible, and the safe passage is unimpeded. As an important visit point for the company, the high standard environment here has always been normalized and has become a model of lean management on site.
With excellent site management, Gao Yang led the smelting section three times won the company's monthly "Lean Management Advanced team" honorary title, won the company's quarterly "Lean Management Advanced section" honorary title. Behind these honors is the day-to-day hard work of Gao Yang and his team members, who interpret the connotation of lean management with practical actions.
Every rush of molten steel is a solemn commitment to the "pursuit of excellence"; Each piece of molded steel billet is a deep praise for the "fire quenching". Gao Yang's story, like an unextinguished fire, lights up the way for countless craftsmen to move forward. Hebei Rongxin Iron and Steel Co., Ltd. all cadres and staff will take innovation as a sword, break through the thorns, break the technical bottleneck; Take responsibility as the shield, adhere to the quality, assume the mission of The Times, inject sweat and wisdom into every production process, and melt a more brilliant monument of hard work on this piece of hot soil!
