Now, two sides of supply and demand is a partnership of common development. The whole process of the use roll including maintenance techniques, the use of technology and technical services, which were got more and more attention in the supply and demand sides. Rolls use side should be provided for all rolls data for supply sides(water pressure, water, water temperature, Tap cooling form, rolling time and rolling tonnage, for roll-for-slot system, Single-off the amount of steel, with a total rolling volume, the user is using the failure occurred roll form, etc.). Roll suppliers, roller in the development of specific varieties of the program production process, it is important to combine specific mill working conditions (water quality) and rolled products, combined with other users before the success of the same material the use of mill experience, determine the best materials and processes production to meet on the roll with the use of performance requirements.
According to the failure of rolls occurred, it is just supply and demand in close cooperation and common analysis of the form rolls and the reasons for the failure, according to the analysis of objective reasons, to take targeted measures to ensure good use of effects and life expectancy.
