The quality of high quality rollers can not be discounted"

In recent years, high speed steel rolls used at home and abroad more than 100 sets of bar mill, the product size precision good abrasion resistance and high rolling circle by love, and enhance the enthusiasm of the development roller manufacturing enterprises of new products, not only to promote the technological progress of roll manufacturing industry, but also to break the hold for decades the traditional roll pattern. The further development of the rolling mill will promote the improvement of the operating rate and the continuous improvement of the rolling process.
However, a product once approved by the society, often accompanied by yijiachongzhen, filled with bad phenomenon of high speed steel roll is no exception. Some enterprises to roll improved indefinite chill roll into semi high speed steel roll to roll enterprise users; some of the users purchase at a very low price to seize the market, but provides the user with the product because the total amount of alloy insufficient, the roll performance index is low, poor wear resistance in multiple rolling line did not reach ideal indicators agreed, even more than ordinary steel cast iron roll. This not only to the supply and demand sides have caused a certain amount of economic losses, but also a direct impact on the user's expectations of a new product roll.
Who has the quality of high quality products, who holds the lifeblood of enterprise survival!" The quality of high speed steel rolls must not be discounted".
In order to make the high speed steel rolls have been improving and improvement in the quality of products, product variety and use more series, in the roll production delivery cycle time is reasonable, the user characteristics and technical guidance on the product in the process of using the more close to the rolling line for high speed steel roll, specializing in the production of rolling thread steel, round steel, strip steel, spring steel flat, as well as for high speed steel roll of high-speed wire rod rolling mill, the development and production of rolls in one set.
Firstly, according to the use of features and mill material will be of high speed steel roll series, followed by the optimization of high speed steel roll component, avoiding the production of centrifugal segregation problems, and improve the heat treatment process of high speed steel roll, enhance roll hardness uniformity. Through the optimization of composition and heat treatment process, the surface hardness of roll body uniformity is less than 3HSD, the processing performance of roll cutting significantly enhanced layer hardness drop is less than 1HSD, the stability of the roll is greatly enhanced, the comprehensive service life of the roller and the former compared to similar products can be extended to about 20%, but the sales price of the roll no growth, won the user's favorite.
On the one hand, it is to reduce the production cost and increase the benefit of the enterprise. On the other hand, it is to improve the surface quality of the rolled material and enhance the market competitiveness of the rolling stock. The quality of high speed steel roll, not only the surface quality of the rolling material can be significantly improved, to enhance the market competitiveness of products, and the service life of the roller length, roll change frequency, the operation rate of rolling mill is high, usually daily output can be increased by about 10%. In general, control negative difference stability rate can be increased by 1%, greatly enhance the production efficiency, increase the efficiency of enterprises.
