Described rolling mill roll cooling device, described baffle plate along roll mandrel to being set to the rectangular plate of arc.
Described rolling mill roll cooling device, cooler and pressure roller and roll vertical center line form the angle of 30 ° and 50 ° respectively.
Owing to adopted technique scheme, the present invention to have following beneficial effect:
1, emulsion gets into through the water inlet of boxlike cooler, and evenly flows to roller surface from the delivery port that cools off the setting of required emulsion amount according to roll; Effectively increase the cooling effect of roll, improved the service efficiency of emulsion simultaneously, avoided a large amount of emulsions sprayed of conventional spout to cause the overcooled phenomenon of roll to take place.
2, baffle plate on roll both sides pressure roller and the support arm and roll form a hemi-closure space; Can make in the operation of rolling in certain zone, roll top and keep certain emulsion amount; And the emulsion that flows out from cooler flows away through the hemi-closure space indentation, there, to prolonging the roll life cycle, reduces roll-force; Improve milling train internal work environment, energy efficient and improve the rolled piece quality effect is preferably all arranged.
3, owing to cooler, press-roller device connect firmly on roll chock through bolt, simple in structure, mounting or dismounting make things convenient for, cost of manufacture is lower.
