High-wear-resistant combined type coiling machine side guide plate

Abstract

The invention discloses a high-wear-resistant combined type coiling machine side guide plate. The high-wear-resistant combined type coiling machine side guide plate comprises lining plates and side guide wheels, wherein the lining plates and the side guide wheels are arranged on the two sides of a coiling machine conveying roller way at intervals, one side guide wheel is arranged at an inlet, wear-resistant alloy strips are mounted on the lining plates, and the surfaces of the side guide wheels are in the same plane as the surfaces of the lining plates. According to the high-wear-resistant combined type coiling machine side guide plate, the sliding friction wear of a steel plate and the side guide plate is changed into rolling friction wear, the side scratch of the steel plate is reduced,and the consumption of the side guide plate is further reduced; the wear-resistant alloy strip has high hardness and thermal shock resistance, and the wear can be reduced; dovetail grooves are machined at the wear parts of the lining plates to mount the wear-resistant alloy strips, bolts do not need to be adopted for fixing, the axial movement of the wear-resistant alloy strips can be avoided, andthe steel plate is prevented from poking to bolt positions to lead to steel heaping at the same time; and in the using process of the high-wear-resistant combined type coiling machine side guide plate, the side guide plate is basically free of the wear, and can be prolonged to half a year for replacement, and only the side guide wheels need to be periodically replaced.

Description

technical field [0001] The invention relates to the field of coilers, in particular to a highly wear-resistant combined coiler side guide plate. Background technique [0002] The side guide plate of the coiler is located at the front end of the coiler. At present, the side guide plate is generally made of traditional Q235 ordinary carbon steel and repaired by surfacing welding. Since the strip often deviates from the center line during rolling, and the material of Q235 is soft and the quality of the surfacing layer is unstable, the single machine cycle of the guide plate is short, the longest single working time is 8-12 hours, and the single replacement time In 20-30 minutes, it seriously restricts the improvement of the operating efficiency of the rolling mill. What's more serious is that the surface quality of the side guides will directly affect the quality of the edge of the steel plate, affect the trimming amount of the steel plate, and even affect the surface quality ...

AI Technical Summary

Problems solved by technology

[0003] 1) The amount of wear is large, and the area in contact with the steel plate is grooved, which affects the quality of the edge of the steel plate, such as: edge sticking, bright bands, scratches, edge cracks, etc., may also cause edge waves, jamming, and stacking of steel ACCIDENT

[0004] 2) The wear of the side guide plate produces filamentous metal debris, which will cause surface quality defects of the steel plate after the debris is substituted into the coiler, and the coiler does not have a surface inspection instrument to monitor the quality of the plate surface, which is prone to batch quality accidents

[0005] 3) The replacement cycle is short and the frequency is high. The short replacement is 2-3 times per shift, and the long replacement is once a day. The single replacement time is about 20 minutes, which affects the rolling rhythm and production efficiency

[0006] 4) The material of the base metal is low, frequent welding causes fatigue of the base metal, and the overall shedding of the welding material occurs after heating, resulting in a quality accident of steel coil slag, and it cannot be reused after repeated surfacing welding for 3-4 times
