Problems solved by technology

[0002] There are more and more developments, researches or applications of grooveless rolling technology on the fully continuous steel rolling process line where the rolling mills are alternately arranged horizontally and vertically, such as "Research and production application of grooveless rolling technology for blooming mills" (《 "Steel Rolling" 1003-9996 (2004) 02-0001-03) and "The Broadening and Application of Flat Roll Rolling" ("Steel Rolling" 1006-5008 (2005) 04-2030-04) are reported; but in the present invention It has not been reported before that the flat roll grooveless rolling process is used in the semi-continuous steel rolling process in which the rolling mill is fully horizontally arranged.

Embodiment 1

[0017] Embodiment 1: as attached image 3 The multi-strand rolling production process shown.

[0018] The multi-line rolling production process of the grooveless rolling process of the full horizontal rolling mill comprises a blooming mill 1, a junior rolling mill 2, a first flying shear 3, a second flying shear 5 and a third flying shear 11, an intermediate rolling unit 4, The first looper 6, the second looper 8, the third looper 9, the fourth looper 10, and the fine hole unit 7. Among them, the preliminary rolling mill 1 is a three-roll mill with a single stand, the junior rolling mill 2 is a two-roll mill, the middle rolling mill 4 is a six two-roll mill, and the finishing mill 7 is an eight two-roll mill (some rolling mills according to different specifications) optional), it is a fully horizontal rolling mill, arranged in tandem, and constitutes a continuous rolling mill. The first flying shears 3 are flying shears for head cutting, the second flying shears 5 are flying...

Embodiment 2

[0021] as attached Figure 4 The single-strand rolling process shown

[0022] From the third rolling stand of the finishing rolling unit 7 (pass type is K 4 ) before the distribution of rolling mills and the distribution of rolling mills in the multi-strand rolling process (attached image 3 ) are the same, the passes of the fourth, fifth and sixth stands of the finishing rolling group 7 are as follows figure 2 K shown 3 、K 2 、K 1 .

[0023] During single-line rolling, the third rolling stand of the finishing rolling unit 7 (pass type is K 4 ) is a flat roll mill, and the flat roll material rolled by it enters the fourth stand of the finishing rolling unit 7 after being twisted by the torsion guide for 90° (pass type K 3 ) is rolled into a round hole-shaped material or a universal hole-shaped material, and enters the fifth rolling mill of the finishing rolling unit 7 through the third looper 9 (the pass type is K 2 ) rolled into a flat ellipse-shaped material, and aft...

Abstract

The invention discloses a slotless rolling art for all-horizontal rolling mill which rolls round bar and screw-thread steel on semi-continuous rolling process online. It arranges junior mill 2, crop flying shear 3, junior mills group 4, crop and crop end flying shear 5, loop 6 or 8 or 9 or 10, finishing mills group 7 and times ruler flying shear 11 after blooming mill 1 consecutively; installs plain-barreled roll 41 or 42 and 71 or 72 on the third or fifth rolling mill frames of junior mills group 4 and the first and third rolling mill frames of finishing mills group 7, the plain-barreled rolls need not be processed hole-type groove, the rolling pressure is decreased significantly. The plain-barreled rolling mills does not have wrong rollers in whole rolling process, does not generate ears, decreases central waste rollers, saves changing roller time, increases rolling mill efficiency. The plain-barreled roll slotless rolling art not only can be used in flat alternative continuous rolling process line, but has a bright prospect in development and application of all-horizontal rolling mill process line.

Description

technical field [0001] The invention relates to a rolling process, in particular to a full-horizontal rolling mill grooveless rolling process for rolling round steel or threaded steel on a semi-continuous steel rolling process line with fully horizontally arranged rolling mills. Background technique [0002] There are more and more developments, researches or applications of grooveless rolling technology on the fully continuous steel rolling process line where the rolling mills are alternately arranged horizontally and vertically, such as "Research and production application of grooveless rolling technology for blooming mills" (《 "Steel Rolling" 1003-9996 (2004) 02-0001-03) and "The Broadening and Application of Flat Roll Rolling" ("Steel Rolling" 1006-5008 (2005) 04-2030-04) are reported; but in the present invention It has not been reported before that the flat roll grooveless rolling process is adopted in the semi-continuous steel rolling process in which the rolling mill...
