Abstract
The invention relates to a pass configuration method for rollers of a rolling mill, wherein a method of mutual overlaying and mutual embedding is adopted when passes are arranged on rollers; more than one pass is embedded into a pass; the inner breadth of embedding pass is less than that of embedded pass; and all the passes can be used for rolling steel materials and do not influence each other. The pass configuration method can arrange a plurality of passes on the limited rollers, improve the utilization rate of the rollers, and solve the problem that more passes can not be arranged because the body length of the rollers is limited.
Description
Technical field
The present invention relates to a kind of collocation method of on rolling-mill roller, arranging pass, belong to the hot-rolled steel section technical field.
Background technology
On roll, process groove, the groove of two or more rolls is assembled up accordingly, form pass.The pass design is the important step that steel rolling is produced, and end product quality, rolling rate, device security, production cost etc. are all had very big influence.
In the pass design configurations of shaped steel rolling-mill roller in the past, all be to arrange mutual nonoverlapping pass schedule successively.Arrange the restriction that how much will be subjected to roll height degree of pass, can not arrange pass more.Be subjected to the influence of roll length, in order to arrange pass to greatest extent, the intersection pass once occurred, the pass that intersects is exactly that two passes intersect mutually, utilizes the barrel length of roll to the greatest extent to greatest extent.
Summary of the invention
In order to overcome the limited and difficult problem that can not arrange pass of roll height degree, the invention provides a kind of pass positioning method of brand-new rolling-mill roller more.
Technical scheme of the present invention is as follows:
A kind of pass positioning method of rolling-mill roller, it is characterized in that on a roll, carrying out the mutually nested configuration of pass, pass is embedded to be with more than one pass, be nested in inside pass less than by the interior fabric width of nested pass, all passes all can be used for rolled steel, and do not influence each other.
Nested pass with should be by the width of the middle collars of nested pass greater than 0.8 times of the darkest groove.
Below be that several different configuration mode of the present invention is as follows:
1, the groove rolling center line is identical.
In the pass setting up procedure, the pass that is nested in the inside should be less than by the interior fabric width of nested pass, and nested pass with should be ruptured to prevent the intermediate calender rolls ring greater than 0.8 times of the darkest groove by the width of middle the collars of nested pass.Mutually nested groove rolling center line is identical.In this pass configuration, can not be by nested pass as the finished product hole.
2, the groove rolling center line is inequality.
The pass that is nested in the inside is less than by the interior fabric width of nested pass, and mutually nested groove rolling center line can be inequality, nested pass with should be by the width of the middle collars of nested pass greater than 0.8 times of the darkest groove, this mode can not be as the finished product hole.
In the mutually nested layoutprocedure of pass, can nested its whole passes at inside pass, a part that also can nested its pass.For example, if roll barrel length is not enough when rolling large H-shaped steel, channel-section steel, I-steel, the several passes that dispose on roll can be taked nested certain a part of method, but last finished product hole can not be so mutually nested.
The present invention creatively proposes the overlapped mutually nested collocation method of pass.This pass positioning method can be arranged a plurality of passes on limited roll, improve the roll utilization rate, solves because of the limited difficult problem that can not arrange pass of roll height degree more.It is novel, reasonable that the design's pass is arranged, solved a technology difficult problem, has the characteristics of roll long service life, satisfied the ordinary production requirement of rolling mill rolled metal material simultaneously.Adopt finished steel that pass schedule of the present invention shuts out through the quality testing department inspection, profile each several part size, presentation quality and inherent quality all meet the technical conditions requirement.
Description of drawings
Fig. 1 is the pass configuration schematic diagram of 1 two passes of embodiment after mutually nested, wherein, the 1st, nested pass, the 2nd, by nested pass, the 3rd, in the middle of collars.Fig. 2 is the flat schematic diagram in hole that rolls of a nested pass, Fig. 3 be one by the schematic diagram in nested pass box-shaped hole.
Fig. 4 is a C pass schematic diagram, and Fig. 5 is a B pass schematic diagram, and shown in Figure 6 is the pass configuration schematic diagram of embodiment 2 passes after mutually nested, the 4.C pass, and the 5.B pass, the 6.A pass, wherein the B pass is mutually nested with the C pass, the shared groove of B pass and A pass.
The specific embodiment
The present invention will be further described below in conjunction with embodiment, but be not limited thereto, and those skilled in the art can determine the concrete mode that pass is mutually nested according to the practical application needs.
Embodiment 1:
A kind of pass positioning method of rolling-mill roller, it is mutually nested to carry out pass on a roll, box-shaped hole 2 pass are nested with one and flatly roll hole 1, are nested in inside flat and roll hole 1 pass less than by fabric width in nested box-shaped hole 2 passes, and two groove rolling center lines are identical.Nested pass is flat roll hole 1 with by the width of middle the collars in nested pass box-shaped hole 2 0.8 times greater than the darkest groove, rupture to prevent the intermediate calender rolls ring.
Present embodiment is according to a kind of new pass system that produce to need design, and two different passes are combined.This pass schedule rolls by a box-shaped hole 2 and one are flat that hole 1 forms, mainly be in order to solve the overproof end to end product defects of big gauge steel, need to increase a flat hole of rolling, the restriction that is subjected to roll height degree is arranged nowhere, by the overlapped collocation method that is nested, make pass of many layouts on the roll.Because increase flat to roll mediate passage and drafts of hole 1 little, be mainly and play the effect of expanding waist, so can not influence product quality because of the influence in box-shaped hole 2.
The applicant produces the H800*300 gauge steel in March, 2008 and adopts this new pass collocation method, solved the overproof end to end product defects of big gauge steel, make lumber recovery bring up to 92.4% by former 88%, the output of every month H800*300 steel is at 5000 tons, and steel scrap price per ton is at 2500 yuan.
Every month economic benefit is: the economic benefit in ten thousand, one year of 4000* (92.4-88) %* (6000-2500)=61.6: 61.6*12=739.2 ten thousand.
Adopt finished steel that this pass schedule shuts out the H800*300 steel through the quality testing department inspection, profile each several part size, presentation quality and inherent quality all meet the technical conditions requirement.
Embodiment 2:
A kind of pass positioning method of rolling-mill roller, it is mutually nested to carry out pass on a roll, shown in Figure 6 is the BD pass of H900X300, B pass 5 is mutually nested with C pass 4, B pass 5 has a groove in C pass 4, C pass 4 has individual groove in B pass 5, B pass 5 and A pass 6 shared grooves, and this designs inadequately in order to solve barrel length.Be nested in inside B pass 5 less than by the interior fabric width of nested C pass 4.Shown in Fig. 4-6.
Claims (2)
1. the pass positioning method of a rolling-mill roller is characterized in that carrying out the mutually nested configuration of pass on a roll, and pass is embedded to be with more than one pass, is nested in inside pass less than by the interior fabric width of nested pass.
2. the pass positioning method of rolling-mill roller as claimed in claim 1, it is characterized in that nested pass with should be by the width of the middle collars of nested pass greater than 0.8 times of the darkest groove.
