High carbon high speed steel roll
High-carbon high-speed steel rolls have the characteristics of good abrasion resistance, good surface quality, excellent anti-accident performance, good consistency of working layer organization, and small hardness drop. They are upgrade products that are incomparable to traditional high nickel-chromium materials. The performance of multiple grinding at one time is of great significance to improve the operating rate of the rolling mill, improve the surface quality of the strip, reduce accident losses, and reduce roll consumption.
R & D background
The high-carbon high-speed steel roll is an upgrade product for the high-nickel chromium and hot-rolled high-nickel chromium after the hot rolling strip, and it is a new type of high-speed steel used in the real-time high-speed steel. .
First, the current hot-rolled strip rolled products are developing in the direction of high-strength steel, high-quality steel, special steel, and hot-rolled sheet steel.
Second, new rolling technology and rolling tempo of steel mills have been further improved.
The third is the traditional high-nickel-chromium rolls, which often have problems such as tail-flicking, rolling, sticking steel, imprints, and water ripples.
The actual use results of major steel mills show that high-carbon high-speed steel rolls can be directly used on the machine without any adjustment to the rolling mill. The nickel-chromium products with high wear on the machine are reduced by half. The roll shape retention ability is strong, and the machine cycle can be more than doubled, which meets the rolling requirements of special varieties such as high-strength steel, high-quality ultra-thin strip steel and ultra-pure ferritic stainless steel.
Create a new era of hot rolling
The new generation of high-carbon high-speed steel rolls surpasses traditional high-speed steel rolls in terms of surface quality and accident resistance. It really advances high-speed steel to the hot-rolled steel strip after finishing rolling, especially the finished product stand, and does not need to do any It can be directly used on the machine after adjustment. Sinosteel Xingji has advanced the world's high-carbon high-speed steel rolls to push the material of the work rolls in the finishing stage of the hot strip mill into a new era.
