Benefits of work roll:
The rolls is an important part of the tension leveler which is mainly used to support the work roll or intermediate roll to prevent the work roll from deflecting and deforming, thereby affecting the output and quality of the plate and belt.The quality characteristics of the work roll include high surface hardness, good hardness uniformity, deep hardening layer of the roll body, good strength and toughness of the roll neck and roll body and body, as well as high wear resistance, good spalling resistance and strong accident resistance.These features enable work roll to play an important role in high-speed, large-scale, high-precision straighteners.
The rolls are used in a wide range of applications, especially in the field of metal processing.They can be used to roll various metal materials, such as stainless steel, carbon steel, aluminum alloy, etc.Because the four-high cold rolling mill has the characteristics of high precision, high efficiency and high stability, it has been widely used in automobile, home appliances, construction and other industries.For example, in the automotive industry, a four-high cold rolling mill can be used to produce automotive sheets, auto parts, etc.; In the home appliance industry, it can be used to produce metal shells for washing machines, refrigerators and other home appliances; In the construction industry, it can be used to produce various metal building materials, such as section steel, steel plate, etc
In addition, the bending technology of the work roll is also an important means to ensure the flatness of the strip.The bending technology is divided into positive bending and negative bending, and by adjusting the size of the bending force, the thickness and flatness of the strip can be effectively controlled, so as to improve the product quality.The application of this technology not only improves the production efficiency, but also enhances the market competitiveness of the product.
Parameter of work roll:
surface quenched HRC63 ~ 65, quenched depth:3 ~ 5mm, chromium plating on roll surface, chromium plating depth 0.03-0.05mm.
In general, work rolls play a vital role in the rolling mill, and their performance and quality directly affect the quality and production efficiency of the final product.
