In order to perfect and improve roll products, what should roll manufacturers do

In order to continuously improve and improve the product quality of high-speed steel rolls and more serialize the product types and application fields, the roll manufacturers should always be reasonable in the roll production and delivery cycle, and be closer to the characteristics of the rolling line and the requirements of users in the technical guidance in the process of product application. They are specialized in producing high-speed steel rolls for rolling thread steel, round steel, strip steel and spring flat steel, And the high-speed steel roll used for the pre finishing stand of high-speed wire rod mill, which integrates the R & D and production of the roll. Today, let the roll manufacturer Wuxi Taihu roll Xiaobian bring you the precautions for improving and improving roll products.

Firstly, the high-speed steel roll is serialized according to the characteristics of rolled products and the application characteristics of rolling mill. Secondly, the composition of high-speed steel roll is optimized to avoid the problem of centrifugal production composition segregation. At the same time, the heat treatment process of high-speed steel roll is improved and the uniformity of roll hardness is enhanced. Through the optimization of composition and the improvement of heat treatment process, the hardness uniformity of roll body surface is not greater than 3hsd, the roll cutting function is significantly enhanced, the hardness drop of working layer is not greater than 1hsd, the stability of roll application is greatly enhanced, and the comprehensive service life of roll can be extended by about 20% compared with previous similar products, but the sales price of roll is not added, which has won the favor of users. In order to make the roll working layer obtain good applicable arrangement, give full play to the effect of alloy elements in the roll, and improve the hardness and wear resistance of the roll body working layer.

On the one hand, the way to get out of the dilemma of the rolling mill is to reduce the production cost and add enterprise benefits; On the other hand, it is to improve the appearance quality of rolled products to a greater extent and enhance the market competitiveness of rolled products. The use of excellent high-speed steel rolls can not only significantly improve the appearance quality of rolled products and enhance the market competitiveness of products, but also have long service life, less roll replacement times, high rolling mill operation rate, and the daily output can usually increase by about 10%. Under normal circumstances, the control rate of negative difference stability can be increased by 1%, which greatly improves the yield and adds enterprise benefits.

In recent years, the high-speed steel roll used in more than 100 sets of bar mills at home and abroad has been deeply loved by the steel rolling industry with excellent wear resistance and high product scale accuracy, which has enhanced the development of this new product by roll manufacturing enterprises, not only promoted the technological progress of roll manufacturing industry, but also broke the traditional roll type format that has maintained for decades. Its further development will promote the gradual progress of rolling mill operation rate and the continuous improvement of rolling process.

OK, the above is the brief introduction of the roll manufacturer to improve and improve the roll products. If you want to know more about roll products and roll manufacturers, please pay attention to the roll manufacturer Wuxi Taihu roll Xiaobian.
