The Prospect of the Adjusting Residual Stress of Cast Iron Roll Technology
In the traditional method of adjustment residual stress of cast iron roll,the natural aging has very long cycle and backlog fund,so it has been gradually phased out;the thermal aging has good effect,but it wastes energy is inefficient;the vibratory stress relief need little energy and gain high-efficiency,but its effect is unstable.Using the compound technology of the thermal aging and the vibratory stress relief can take advantages of both.We can consciously carry on vibration treatment by making full use of wasted time and heat in each links of the roll cycle.As a result,it can be not only with no additional aging time and energy but also the effect is improved.The thermal and vibration compound aging technology is the ideal way in adjustment residual stress of cast iron roll.
