Research for PC mill zero-adjustment deviation control method

By analyzing zero-adjustment and roll system during production for 1580 PC in Baosteel Co.,Ltd.,A new cross-head clearance compensation proposal has been raised,which could control cross original of the roll system effectively.With zero-adjustment proposal,the roll systems will be in parallel and rolling force deviation will be reduced effectively during the zero-adjustment process,hence the PC cross angle setting make the roll-symmetric cross into effective,improve the stability of the rolling process.The results of the research have practical value.
