Design and Application of Centralized-circulation Treatment System for Rolling-oil for Steel Tube Cold-rolling Process

Briefly analyzed here in the paper are the advantages and disadvantages of the single-unit independent circulation-treatment system for rolling oil for the steel pipe cold-rolling process.Accordingly a centralized-circulation system for the same purpose is proposed and actually designed.The elaboration focuses on such aspects as characteristics of the said system,and the system’s design scheme,including the centralized circulation/filtering system,the return-flow system,the oil-supply system and the control system,etc.The said rolling oil centralized circulation treatment system as designed features short implementation cycle and comparatively small general investment.The system will,after putting into operation,not only get production cost saved,but also meet the applicable environment protection criteria.
