Described flatness refers to the integral planar degree of the pressure-bearing surface that roller system framework directly contacts with back-up chock, and described flatness is 0.05mm to 5mm.
Described supporting roller refers to quantity the backing roll number that support working roll axially.
Described supporting roller is 3 to 10 to quantity.
Described middle part backing roll and working roll gap refer to assemble the gap between the backing roll body of roll of rear actual measurement and the working roll body of roll, centered by described gap is divided along backing roll and working roll axis direction and both sides, described center refers to first backing roll that the mid point of working roll barrel length extends to direction of both ends, described both sides refer to the outermost backing roll that non-central and mid point that is inoperative roller barrel length extends to direction of both ends, and the gap of described center and both sides is containing 0.05mm to 0.2mm.
Cushion pad in described cushion pad thickness is placed between back-up chock and roller system framework pressure-bearing surface when assembling.
The cushion pad of described cushion pad refers to the pad that steel, copper, aluminium material make.
Described backing roll chamfering length refers to that the body of roll two ends chamfering of backing roll and working roll contact portion is along supporting roller length upwards, other parameter of described backing roll chamfering according to body of roll structural adjustment, described backing roll chamfering length 15mm to 30mm.
Beneficial effect of the present invention draws by such scheme: owing to have employed brand-new parameter adjustment scheme, solve domestic straightener to lack and meet national conditions, highly versatile, strong adaptability, the easy to operate and technical barrier of lower-cost assembly method, there is following beneficial effect: the assembling standard that the invention provides quantification, easy to operate.This invention does not need additionally to increase expense except cushion pad, and cost is low.This invention by roll system structure and working roll, the quantitative limitation of backing roll number, highly versatile.Adopt the roller system that this invention is assembled, stable, failure rate is low, leveling effect is good, and straightening capacity can be played to greatest extent.This invention meets national conditions, is convenient to penetration and promotion.
As can be seen here, the present invention compared with prior art has substantive distinguishing features and progress, and its beneficial effect implemented also is apparent.
