Study on Power of Coilers in Baosteel No.3 Hot Strip Rolling Mill

Liao Yongfeng,Jiang Guangbiao(Hot Strip Rolling Plant,Baosteel Branch,Shanghai 200941,China)  
A coiler unit is chosen on the basis of the requirement that the highest hot yielding strength of a product be up to 700MPa and the lowest coiling temperature be under 200℃ in No.3 Hot Strip Rolling Mill,especially,on the basis of the limited product specifications.Through analyzing,calculating and checking pinch rolls'pinching force,the pinch roll motors' maximum load torque and overload torque,and the mandrel motors' overload torque,results indicate that the key parameters chosen for coilers in No.3 Hot Strip Rolling Mill are reasonable,and can meet the requirements of product specifications and production processes.
