Description

Roller pass structure joined by a kind of H profile steel edging mill that effectively can reduce roller consumption

Technical field

The utility model relates to a kind of H profile steel edging mill that effectively can reduce roller consumption and joins roller pass structure, genotype steel rolling technical field.

Background technology

During modern H profile steel is produced, the general compact arrangement mode of two frame universal mill intermediate tie one frame edging mills that adopts carries out reciprocal rolling, and wherein edging mill can carry out quick traversing aligning hole slot, and guide and guard can on-line tuning position.The effect of edging mill mainly controls H profile steel top flange shape, can control flange width simultaneously, not have drafts to web.Roller aperture type joined by edging mill mainly affects by barrel length L and H profile steel rolled piece web height, and it is joined roller aperture molded breadth degree, joins roller web width and join roller depth of groove and is determined by H type rolled piece product specification.Existing roll structure of joining comprises outer collars, groove and web, and web is positioned at the middle part of joining roller, and width and H profile steel rolled piece web height match; The pass of this kind of structure only effectively utilizes the middle part of roll surface, and utilization rate is lower, when the H profile steel of rolling small size web, cause the waste of joining roller both sides major part roll surface, the increase that roller certainly will be caused like this to consume, makes production cost remain high, the economic benefit of remote-effects enterprise.

Utility model content

Technical problem to be solved in the utility model is to provide a kind of pass structure that effectively can promote edging mill and join roller roll surface utilization rate, designs more hole slot in existing joining in roller length, improves roll surface utilization rate, reduces roller consumption, solves background technology defect.

The technical solution of the utility model is as follows:

Roller pass structure joined by a kind of H profile steel edging mill that effectively can reduce roller consumption, join roller aperture molded breadth degree, join roller web width and join roller depth of groove and determined by H type rolled piece product specification, its improvements are: comprise left side outer collars, the first web, edge of a wing pass groove, the second web, edge of a wing pass groove along joining roller barrel length L direction order ... collars outside n-th web, edge of a wing pass groove and right side, spacing on the left of n-th web on the right side of the (n+1)th web is identical with joining roller web width, and matches with H profile steel web height; The edge of a wing pass groove degree of depth is identical with joining roller depth of groove; Edge of a wing pass groove width is omnipotent first passage edge of a wing thickness ± (10-15) mm; N-th web width is 0.8-2 times of the edge of a wing pass groove degree of depth.

Roller pass structure joined by above-mentioned a kind of H profile steel edging mill that effectively can reduce roller consumption, and outside described left side, outside collars and right side, the width of collars is greater than the width of edge of a wing pass groove.

Roller pass structure joined by above-mentioned a kind of H profile steel edging mill that effectively can reduce roller consumption, keeps 2-3mm gap between described n-th web and H profile steel rolled piece web.

The beneficial effects of the utility model:

Employing the utility model is applied to the edging mill in H profile steel production, and join on roller at existing edging mill and utilize nested thinking to design roll shape, be nested with edge of a wing pass in pass web width scope, different product configuration groove rule is as follows:

1) as WF > 180+1.6D:

If $\frac{2L}{n+2}<L_1\&le;\frac{2L}{n+1},(n=1,2,3...),$ A then configurable n pass.

2) as WF > 90+1.6D:

If a then configurable n pass.

In formula: L for join roller length, WZ for join roller aperture molded breadth degree, WF for joining roller web width, D is edge of a wing pass groove depth.

The utilization rate that edging mill can be joined roller by the utility model improves 50% ~ 100%, reduces ton steel rider consumption, has significant economic benefit.

Accompanying drawing explanation

Fig. 1 is that rolling view joined by existing edging mill;

Fig. 2 is the utility model schematic diagram;

Fig. 3 is the utility model as-rolled condition schematic diagram;

Be labeled as in figure: edging mill join roller 1, rolled piece 2, edge of a wing pass groove 3, first web 4-1, the second web 4-2 ... n-th web 4-n (n=3,4 ...), collars 6 outside collars 5, right side outside left side.

Detailed description of the invention

The utility model is joined roller aperture molded breadth degree, joins roller web width and is joined roller depth of groove and determined by the specification of H type rolled piece 2, left side outer collars 5, first web 4-1, edge of a wing pass groove 3, second web 4-2, edge of a wing pass groove 3 is comprised along joining roller 1 barrel length L direction order ... n-th web 4-n (n=3,4 ...), collars 6 outside edge of a wing pass groove 3 and right side, spacing on the left of n-th web 4-n on the right side of the (n+1)th web is identical with joining roller web width, and matches with H profile steel web height; The edge of a wing pass groove degree of depth is identical with joining roller depth of groove; Edge of a wing pass groove width is omnipotent first passage edge of a wing thickness ± (10-15) mm; N-th web 4-n width is 0.8-2 times of the edge of a wing pass groove degree of depth, keeps 2-3mm gap between the n-th web 4-n and middle rolled piece 2 web of H profile steel; Outer roller ring width is greater than edge of a wing pass groove width.

The utility model is applied to the edging mill in H profile steel production, joining on roller at existing edging mill utilizes nested thinking to design roll shape, and be nested with edge of a wing pass in pass web width scope, utilization rate edging mill can being joined roller improves 50% ~ 100%, reduce ton steel rider consumption, have significant economic benefit.
