Application of new technologies on the hot strip mill

Body rolling. Billet temperature of austenite into the middle of finishing mill, the first five racks austenitic rolling, and then strip about 18m in the middle of the cooling section to cool. Austenite into ferrite,[link widoczny dla zalogowanych], and then in the next two racks ferrite rolling, rolling to the final product thickness. Thyssen think. The middle thickness of the best 3 ~ 6mm, with the last two racks rolled to finished thickness of 0.8mm ~ 1.5rrml: At this point the best of ferrite rolling temperature range: Ar. ~ Arl a 150 ℃. Strip at the exit of the fast cooling, the cooling rate should be larger than 10 / s, so that recrystallization does not occur strip. Using this technology,[link widoczny dla zalogowanych], the strip is very suitable for deep drawing processing section 5 Yinhong: application of new technologies on the hot strip mill and cold rolled 3: 4 Conclusion The application of a variety of plant SSAB Swedish-line computer control model and some new equipment examples of successful transformation, and new austenite / iron chain body Recovering rolling process, can in our Hot Strip Mill Plant transformation of existing production facilities and new rolling process to get promotion and application. Less capital investment, almost does not affect the normal production and management. Improve product quality, development and production market in urgent need of thin gauge hot rolled products. Maximize the economic efficiency of enterprises Reference [t. P cylinder SixTenkmn. EricNeldelmNEWPROCESSTECHNOIOGLESANDAUTOMAl ¨ ONSYSTEMSFORHOTR \● ● ● ... eleven Pohang Iron and Steel Company in 2000 to create more than one trillion won Pohang l technical efficiency through the development of the company has consistently low-cost,[link widoczny dla zalogowanych], high value-added and environmentally friendly technology to improve the competitiveness of enterprises, thereby developing the world's unrivaled iron and steel manufacturing company. In 2000 alone not only reduce the cost of the profit increase, and based on years (average 4-5 years, the general benefits of new technology to create a cycle) based on the development of technology has made some breakthroughs, also contributed to profits and productivity. Pohang benefits last year, the rapid response to technological innovation, largely due to the low-cost technologies and waste recycling technologies (Gen. 690 billion won), and energy-saving technology (Gen. 350 billion won). The company's quality improvement (reduction of product defect rates) and high value-added products (Genesis 60 billion won) the development has also made great progress: Iron has made great progress, the company by improving the ventilation rate to improve blast furnace pisolite cheaper iron utilization,[link widoczny dla zalogowanych], increased 341% from 302% to 37.0% ~ 37.4%. Moreover, also developed the technology to improve the utilization of cheap coal to make it from 22% to 48%, trapped in this lower production costs significantly. In the COREX plant, POSCO has developed a new technology to improve fuel efficiency of coal furnace coal is made of the required size at room temperature. To improve the stove's ventilation rate and greatly reduce coal consumption. In addition, the development of high value-added products, Pohang developed 25 new products, including car bumpers and oil pipes with a cold rolled steel hot rolled coil 600M level, and 19 types of environment-friendly products, including home appliances and construction coatings board (excluding Cr,[link widoczny dla zalogowanych], has been reported that cr harmful to the environment): The results for the Pohang open a new market demand, the annual demand for 37 million t. POSCO has developed a car with a coated steel outer panel (GASuper.EDDQ), and lrv picture tubes rolled plate, completely replace the imports. POSCO is to the development of new technologies as the basis to calculate the value of last year to create the technology, but also to the different process parameters, equipment and operating conditions such as Nippon Steel of Japan, Germany, Thyssen. Krupp as reference, compared to a competitive technology in the practice after considering the above factors together, that POSCO has basically mastered the representative of the world advanced level of technology. In order to further enhance their enterprise value, which has been the core operating principle of Pohang, POSCO's mid-term technology development plan is based on the pursuit of globally competitive technology as the unique target for 5 years following a breakthrough 5 ; development of high value-added products; develop low-cost technology; develop user-oriented technology; development to meet the most stringent environmental regulations, environmentally friendly technology; and the development of innovative technologies Pohang its own characteristics. POSCO plans As of 2005, a total of 87 trillion won invested to promote the following: to expand stainless steel production capacity and develop management methods will help improve the company's technology to become the world's most competitive enterprises.
