In actual production, in the specific steel processing stage, the defects that affect the quality of hot-rolled strip are explored and researched, and the technical problems and the ways to solve the problems are found, which will improve the overall production quality of the steel industry. Corresponding costs and improving the qualification rate have very…
Flame cleaning machine dust removal 1.1 The flue gas generated by the flame cleaner should be controlled,and the dust removal design should consider the characteristics of dust concentration,flue gas moisture content,iron trioxide content in dust,dust particle size etc. 1.2 A detachable movable fume hood is set at the passing part of the blank mold of…
At about 12:00 on September 8, 2020, a red continuous casting slab with a mission started from No. 7 caster. Originally, it needs to be hoisted to the storage area, waiting for the billet to be transported to the heating furnace by car. This time, it is directly transported to the straight rolling rod track.…
The “Integration of Steelmaking, Continuous Casting and Rolling” plan integration and scheduling technology, automatic control technology and comprehensive shape control technology have been developed into key common technologies in the production process of hot-rolled wide strip steel, which are important for energy saving, product quality control, and enterprise economy. Increased efficiency is decisive. The…
The finishing roll mill unit of a high-speed wire factory adopts a 45° top-crossing cantilever rolling mill designed by Italian DANIELI company, which was put into use in 2015, and its main production wire specifications are Ф5.5 to Ф16mm. The unit is composed of eight rolling mills, and the maximum designed speed of the mill…
This paper introduces the typical high speed bar production process layout and the key equipment of high speed upper steel system The working principle has certain guiding significance to the maintenance and production organization of high-speed bar equipment. With the development of new technology of rolling equipment, the production of bar in steel works has…
Foreword: In order to meet the needs of the next work, it is necessary to carry out the analysis of the roll of the bar mill. This needs to analyze the characteristics of the precision frame, better analyze the performance characteristics of the frame roll, and systematically expound. Better analysis of material modules, application modules, etc., to ensure the improvement of its overall quality, to achieve its overall performance improvement, better meet the needs of the current work module.
In order to overcome the segregation defect of high-speed steel roll in centrifugal casting, Nippon Steel Co., Ltd. developed the c-matching method (continuous casting outer layer forming method) for manufacturing high-speed steel roll. 1 it has the characteristics of energy saving and good roll performance. Its basic principle is to cast the molten steel as…
What’s process of operation of online steel bar counting and separation system? How to operate control panel? The system is divided into several working states: star-up state, setting state, counting state, steel-splitting state and exit state. Under automatic counting state, it may operate as follows: When stopping chain bed or there are not bars…
Kocks cemented carbide roll rings for Kocks three-roll mill to replace the original ball-milling of cast iron roll ring,mainly the production of bearing steel,spring steel,alloy steel and other special steel,steel surface and tolerance controls are clearly better than cast iron roll ring and wear-resistant is good,life is a cast iron roll ring 10 times
