Anti-scratch device for bottom of horizontal looper in high-speed wire rolling

Abstract

The invention belongs to the field of processing of high-speed wires in a steel rolling mill and particularly relates to an anti-scratch device of the bottom part of a horizontal loop for rolling high-speed wires. The device comprises a support guide bottom plate which is horizontally arranged in the loop along the wire progressing direction; horizontal guide rollers are horizontally arranged at a front end inlet and/or a rear end outlet of the horizontal loop on the support guide bottom plate; the axial directions of the horizontal guide rollers are vertical to the length direction of the support guide bottom plate; the horizontal guide rollers are embedded into the support guide bottom plate; the top ends of the roller surfaces exceed the support guide bottom plate; a guide roller groove used for mounting the horizontal guide rollers is arranged in the support guide bottom plate; an offset push rod groove used for detecting is also formed in the support guide bottom plate; the offset push rod groove is provided with an arc groove bottom and a groove opening which is formed in one side of the support guide bottom plate; a wire detection channel area is formed between the groove bottom of the offset push rod groove and the other side of the support guide bottom plate on the support guide bottom plate. By arranging the guide rollers which are simple in structure and convenient to mount, the seams, folding and drawing defects caused by the original sliding friction are effectively eliminated, and the wire rolling surface quality is improved.

Description

technical field [0001] The invention belongs to the field of high-speed wire rod processing in steel rolling mills, and in particular relates to an anti-scratch device for the bottom of a horizontal looper for high-speed wire rod rolling. Background technique [0002] In the existing high-speed wire rod production line, the wire rod and the bottom plate in the horizontal loop between the frame and the frame all use sliding friction. When stainless steel is produced and rolled, the product quality requirements are much higher than those of conventional steel types. , it is very easy to cause scratches to red steel, which may cause quality problems such as seams, folding, and wire drawing. There are many points of production, folding, and drawing, and it is difficult to find out the occurrence points of seams, folding, and drawing problems. The depth of seams, folding, and drawing of finished products is unobstructed between 0.03-0.15 mm, especially for steel types that are ea...

Problems solved by technology

[0002] In the existing high-speed wire rod production line, the wire rod and the bottom plate in the horizontal loop between the frame and the frame all use sliding friction. When stainless steel is produced and rolled, the product quality requirements are much higher than those of conventional steel types. , it is very easy to cause scratches to red steel, which may cause quality problems such as seams, folding, and wire drawing. There are many points of production, folding, and drawing, and it is difficult to find out the occurrence points of seams, folding, and drawing problems. The depth of seams, folding, and drawing of finished products is unobstructed between 0.03-0.15 mm, especially for steel types that are easy to scratch such as Copper-containing steels 304HC, 303Cu, 316LCu, high-strength steels 304H, 316 and other steels are particularly sensitive and have a great impact on subsequent processed products, especially in hot metal detectors used to adjust the rolling speed of the front and rear racks Position, the wire is pushed to one side to bend, due to the weight of the wire itself, the bending position and the front and rear sides of the bending position are easily scratched by the bottom plate
