Problems solved by technology

[0002] In the production of stainless steel wire rods, the roll rings of the finishing mills slip and the roll rings cannot be removed frequently, which affects the normal production of stainless steel wire rods. It not only causes scrap steel in the middle, wastes energy, but also increases the cost of spare parts, and also increases the failure time, which is even more serious. What is more, the product quality cannot be guaranteed

Embodiment Construction

[0010] When checking the shaft head, remove the rust with water sandpaper, scrub the shaft head clean, check whether there are protrusions or sharp edges in the shaft head window, and if there are protrusions or sharp edges, use a steel file to grind them.

[0011] Use a standard taper sleeve and put it on the shaft head. Check whether the taper sleeve is in contact with the straight section of the shaft head. If the taper sleeve is not installed properly, it means that the straight section of the shaft head is deformed and contacts the taper sleeve. Grinding the shaft head. If it is not ground, it will be difficult to disassemble after assembly, and the taper sleeve may be pulled out, and the roller ring may even be scrapped. Generally, an outer diameter micrometer is used to measure the outer diameter of the taper sleeve after deformation at 5-6 points of the taper sleeve. , when the difference in average size is greater than or equal to 0.04mm, the size of the cone surface o...

Abstract

The invention relates to a finishing mill collar assembly and detection method, aiming to increase the assembly quality of the wire stock finishing mill collar and reduce the fault. The method of the invention comprises the following steps: sleeving a collar on an axle head through a taper sleeve, exerting an axial force to the taper sleeve to ensure that the taper sleeve generates elastic deformation and no relative displacement exists between the collar and the axle head; using a 0.05-0.10mm of filler gauge to detect whether the straight-line segment of the axle head and the taper sleeve has the clearance or not, wherein if part of the filler gauge can not be squeezed in, the grinding deformation point is needed to be removed for installing the filler gauge again; installing the standard taper sleeve without the collar on the axle head to be measured, pressurizing to 20MPa, and using an outside micrometer to separately measure the outside diameter of the deformed taper sleeve at a plurality of positions for comparison, wherein when the average difference reaches 0.04 mm, the axle head of the mill is needed to change.

Description

technical field [0001] The invention relates to a method for assembling and detecting roller rings of a finishing mill in a wire rod rolling system. Background technique [0002] In the production of stainless steel wire rods, the roll rings of the finishing mills slip and the roll rings cannot be removed frequently, which affects the normal production of stainless steel wire rods. It not only causes scrap steel in the middle, wastes energy, but also increases the cost of spare parts, and also increases the failure time, which is even more serious. Unfortunately, product quality cannot be guaranteed. Contents of the invention [0003] The purpose of the present invention is to overcome the shortcomings of the above-mentioned prior art, and provide a finishing mill roll ring assembly detection method that can improve the assembly quality of the wire rod finishing mill roll ring and reduce faults. [0004] The inventive method is: [0005] (1) Roll ring installation: The r...
