Abstract

The utility model discloses a guide device for rolled pieces to enter in and out of a groove in the H-section steel rolling process, which belongs to the technical field of the rolled steel process equipment. The guide device is characterized in that stoppers with width being one-half smaller than the width of a guide plate are respectively installed on the foreplates of guide devices between an E rolling mill and a UR rolling mill as well as between the E rolling mill and a UF rolling mill, and parts of the two adjacent stoppers are overlapped in the rolling direction. The guide device has the advantages of simple structure and secure and reliable control; the phenomenon of piling-up of steel caused by rolled piece ski-up and head end curling can be avoided; by modifying the guide device of the rolling mill, the rolling stability can be enhanced, the rolling precision is improved, the phenomenon of piling-up of steel is avoided, the workefficiency of the rolling mill is improved, and the increase of the production capacity is promoted; and the guide device has remarkable economic benefit and social benefit.

Description

Alternating expression guide device

Technical field

The utility model discloses a kind ofly in H rolling of sectional iron technology, the guide and guards of rolled piece turnover pass belongs to the steel rolling processing equipment technical field.

Background technology

Guide and guards is the important accessory in the milling train, is used for guiding rolled piece correctly to pass in and out the device of pass.Generally be made up of following parts: 1, guide plate is positioned at the both sides before and after the pass.Guide plate before the pass induces rolled piece to enter pass, and the guide plate behind the pass can prevent that rolled piece from forming bending at horizontal plane; 2, defend plate, be positioned at the upper and lower behind the pass, can prevent that rolled piece from producing collaring; 3, the crossbeam that foreplate is used is installed, is fixed on the frame.

Laigang big H type steel production line capital equipment by the design of German SMS company, make, mm finishing mill unit is made up of UR, E, two universal mills of UF, an edging mill, employing X-H's is reciprocating type rolling.The finish rolling zone does not have delay table, relies on guide and guard to carry out transition between three rolling mills.In H rolling of sectional iron technology, because the special shape of rolled piece, than higher, the guide and guards in the H rolling of sectional iron technology is made up of two parallel foreplates up and down, is the important component part of pass to the requirement of guide and guards.Its effect is to make rolled piece by needed state turnover pass, guarantees that rolled piece is rolled by the predetermined deformation condition.Because the roll laterally mobile and each rolling pass when rolling off the production line on the milling train is adjusted up and down, must assurance face interval 50 millimeter between the rolling mill guiding mutually.Because blank is subjected to the influence of factors such as technology adjustment, blank section, temperature difference change in rolling, occur nose, discount, inclined to one side phenomenon easily, cause the heap steel thereby get out the guide and guard gap, cause the accident.

Summary of the invention

The utility model is at the deficiency of prior art, a kind of working stability is provided, can effectively avoids occurring nose, discount, inclined to one side phenomenon, thereby made rolled piece get out the alternating expression guide device that the heap steel is caused in the guide and guard gap.

Technical characterictic of the present utility model is to install the block of width less than foreplate width 1/2nd respectively on the foreplate of the guide and guards between E milling train and UR, the UF milling train, and adjacent two blocks overlap on rolling direction.

Of the present utility model being constructed as follows: a kind of alternating expression guide device, crossbeam by foreplate and installation foreplate constitutes, it is characterized in that facing mutually between the guide and guards of milling train and install the block of width less than foreplate width 1/2nd respectively on the foreplate, adjacent two blocks overlap on rolling direction.

During work, install the block of width on the foreplate respectively less than foreplate width 1/2nd, adjacent two blocks overlap on rolling direction, make two neighboring sections foreplate connecting portion can effectively avoid rolled piece nose, discount, inclined to one side phenomenon to occur, thereby get out the guide and guard gap, cause heap steel accident.

The utility model is simple in structure, control is safe and reliable, can stop because of rolled piece end bending and the caused heap steel of discount phenomenon.Transformation through to rolling mill guiding can improve rolling stability, improves rolling accuracy, stops to pile the steel phenomenon, improves operating rate of rolling mill, promotes the lifting of production capacity.Have remarkable economic efficiency and social benefit.

Among the figure: 1-UR milling train inlet is gone up guide and guard, the guide and guard down of 2-UR milling train inlet, horizontal roller on the 3-UR milling train, horizontal roller under the 4-UR milling train, guide and guard are gone up in the outlet of 5-UR milling train, 6-UR milling train outlet guide and guard down, 7-E milling train inlet is gone up guide and guard, the guide and guard down of 8-E milling train inlet, horizontal roller on the 9-E milling train, horizontal roller under the 10-E milling train, guide and guard are gone up in the outlet of 11-E milling train, 12-E milling train outlet guide and guard down, 13-UF milling train inlet is gone up guide and guard, the guide and guard down of 14-UF milling train inlet, horizontal roller on the 15-UF milling train, horizontal roller under the 16-UF milling train, guide and guard are gone up in the outlet of 17-UF milling train, 18-UF milling train outlet guide and guard down, 19,20,21, the 22-block.

The specific embodiment

A kind of alternating expression guide device, crossbeam by foreplate and installation foreplate constitutes, it is characterized in that facing mutually between the guide and guards of milling train and install the block of width less than foreplate width 1/2nd respectively on the foreplate, adjacent two blocks overlap on rolling direction.

Specifically shown in Fig. 1-4: install the block of width respectively on the foreplate installing between the guide and guards that faces milling train mutually respectively on the guide and guards between E milling train and UR, the UF milling train less than foreplate width 1/2nd, see 19 among Fig. 3,20,21,22 adjacent two blocks overlap on rolling direction, see 19 among Fig. 4,20.Thereby the gap between the elimination guide and guard can be stopped like this because of rolled piece end bending and the caused heap steel of discount phenomenon.Through milling train being led the transformation of position, can improve rolling stability, improve rolling accuracy, stop to pile the steel phenomenon, improve operating rate of rolling mill, promote the lifting of production capacity.

Claims

1, a kind of alternating expression guide device, crossbeam by foreplate and installation foreplate constitutes, it is characterized in that facing mutually between the guide and guards of milling train and install the block (19,20,21,22) of width less than guide plate width 1/2nd respectively on the foreplate, adjacent two blocks overlap on rolling direction.
