Design of mill roll cooling result test device

Abstract: Currently effective roll cooling on the intensifying competition in the markethas become the top priority of each enterprises improve their competitiveness.As a project of more capital, roll consumption,the length of the roll service life is the most direct performance.Mill roller testing the effect of cooling device is based on the principle of rolling mill work roller cooling technics of speed regulating motor and the size and direction of water jet is adjustable,and heating temperature control device,any working conditions needed to complete the rolling mill,is the modern rolling mill rolling mill roll cooling effect important experimental equipment of test apparatus.This article mainly aimed at the mill roller test unit cooling effect of system control equipment research and development,process for the rolling mill roll cooling effect test device under effective control.In addition, the temperature control device, the speed control device,the control device of cooling water, etc.Through changing  parameters,the best roll cooling parameters have been found.Test device has the function of roll heating, temperature,test apparatus capable of injection Angle, nozzle installation position,adjusted by the parameters such as jet distance, jet flow,To ensure the dependability of the construction,it is necessary to check all the parts of the stiffness and strength calculation.                     

Key words ：rolling mill roll cooling effect test device, heating, spray adjustable device, speed adjustment device
