New Generation Medium and Heavy Plate Work Roll
Sinosteel Xingji independently developed the world's most advanced 5000mm-grade high-temperature, quenching and cooling equipment, and successfully developed a new generation of medium-thickness plate series work rolls through a variety of material design and process means. And high-speed steel) to a higher level. With a maximum production capacity of Φ1600 × 6000 × 12000mm wide and thick plate work rolls.
The new generation of medium and thick plate work rolls has obtained a higher strength martensite structure, which meets the rolling of high-strength steels, and solves the problems of non-wear resistance and poor thermal cracking resistance of traditional materials. The single consumption of the roll is reduced; the oxide film on the roll surface of the product is well formed and dense, showing good roll surface and roll shape retention ability; it provides guarantee for rolling high strength steel and high surface quality steel plate.
R & D background
Medium and heavy plates are widely used in special fields such as urban construction, ships, pipelines, and military industries. The rolling level is an embodiment of the country's comprehensive national strength and is of great significance to the development of the national economy.
In 2007, Sinosteel Xingji invested in a 5000mm extra-large centrifuge and established a production line for medium and wide plate work rolls. In 2010, 5000mm wide and thick plate work rolls were domestically produced, ranking first in the world. However, in terms of materials, ICDP or improved ICDP materials are still widely used in wide and thick plate rolling lines. With the steady growth of China ’s medium and heavy plate rolling output and the continuous increase in high-strength steel rolling requirements, problems exposed in the use of ICDP rolls have severely restricted the improvement of medium and heavy plate rolling.
The development and application of high-speed steel products in medium and heavy plate work rolls has greatly promoted the development of rolls and steel rolling business.
The new generation of medium and heavy plate rolls developed by Sinosteel Xingji has been supplied to major medium and heavy plate rolling lines nationwide, and exported to Australia, Mexico, South Korea, etc. The variety covers medium and wide plate and furnace coil rolling lines to meet the high strength steel rolling The demand is of epoch-making significance in the upgrading of the material of the work plate of medium and thick plates.
