Embodiment 1

[0038] A treatment method for furnace roll nodulation, said method comprising the steps of:

[0039] Make a mark at the exit of the furnace, that is, use a screwdriver to draw a line on the strip surface on the outer strip of the last stick at the exit of the annealing furnace as a mark, and determine the number of the furnace roll caused by the nodulation of the furnace roll and the number of the furnace roll in the furnace according to the grinding mark. The transverse width position on the roll. Prepare another roll of new strip steel transition volume, and described new strip steel transition volume is the electrical steel strip steel coil of the same material. Holes are punched on said new strip transition coil, the hole diameter The edges of the holes are flush with the strip, so that holes are distributed (intervals) across the width of the plate.

[0040] According to the nodulation width position reflected on the strip steel, the strip steel position corresponding ...

Abstract

A treating method of a furnace roller nodule comprises the following steps: (1), after a machine shuts down, a mark is made on band steel in the outlet position of a furnace, a furnace roller is rotated, and according to a furnace roller nodule marking ground on the band steel, the number of the furnace roller where the furnace roller nodule is generated and the transverse width position on the furnace roller are determined; (2), a new band steel transition roll is prepared and is an electrical steel band roll made of the same material, holes are formed in the new band steel transition roll, the hole diameter is in a range from 1.5 mm to 2.5 mm, and the hole edges are flush with the band steel, so that the holes are uniformly distributed in the overall width direction of a whole plate; (3), according to the nodule width position reflected on the band steel, the band steel provided with hole groups in corresponding widths is placed in the furnace roller position; (4), the band steel tension is removed, so that the band steel droops and forms a wrap angle with the furnace roller; and (5), the furnace roller rotates independently at a slow speed, so that the furnace roller rotates relative to the band steel, the furnace roller nodule is bulged out of the surface of the band steel when abraded on the holes in the surface of the band steel, and the furnace roller nodule is removed by the hole edges during rotating.

Description

technical field [0001] The present invention relates to the field of metallurgy. Specifically, the present invention relates to a treatment method for furnace roll nodules. The furnace roll nodule treatment method can remove furnace roll nodule marks without performing hot roll changing operations, thereby ensuring product quality. , which saves energy and ensures stable production of the unit. Background technique [0002] Usually, the metallurgical silicon steel workshop has several non-oriented electrical steel continuous annealing coating lines (hereinafter referred to as: SACL unit), and the SACL unit is a horizontal continuous annealing coating unit (such as figure 1 ), the length of the furnace is more than 200 meters, and there are a large number of carbon-coated furnace rolls in the furnace. The furnace roll Φ180mm×the length of the roll surface is 1860mm). At present, there is no effective way to remove the furnace roll marks. The general method is to run a roll o...
