Abstract:
     This invention is a kind of noise reducing oil used in the metallurgical industry for eliminating the noise on the process of straightening rails. The aim of the invention is to eliminate the great noise generated by the rail when being straightened. This kind of noise reducing oil can be compounded by mixing the no. 30-50 mechinery oil with tributyl phosphate ester. Not only can it eliminate or reduce the great noise produced by whatever heavy or light rail during the straightening process, but also can it reduce the noise caused by autogenic vibration due to friction.
