Through cooperation with a number of well-known metallurgical design and research institutes and steel enterprises as well as many years of technological experiences accumulation, the performance of Short-stress Rolling Mill manufactured by this Company has been gradually improved and well received by customers in the industry at home and abroad. The rolling mill extensively adopt branded four-row cylindrical roller bearings with large load-bearing capacity. It possesses excellent self-defensiveness, high precision and long service life. Roll balancing method: Elastic damping shock absorber or laminated spring elastic damping balance is adopted. Certain rolling mills are provided with additional hydraulic assistance, which makes the balance effect more stable. The radial adjustment of roll adopts hydraulic motor and manual symmetrical adjustment, and the accuracy tolerance of screw-down worm gear reaches 7. The rolling mill is fixed conveniently and efficiently. The axial adjustment of roll adopts built-in worm gear locked with front and rear double bolts. The adjustment control ends of horizontal and vertical rolling mills are leading out to assure safe and convenient on-site adjustment. Φ350-series model adopts both-side axial locating, with better stability. The mechanical pull rod and bearing seat are sealed with multi-layer coated seal, with excellent waterproof, dust-proof and corrosion protection performance and low failure rate. Lubrication method: Grease, air-oil as well as composite lubrication can be used based on different user requirements. The rolling mill manufactured by this Company has compact structure and light weight, with convenient, fast and efficient roll and frame replacement.
