Description

TECHNICAL FIELD

[0001] The present application relates to the field of high-speed wire rod production in the metallurgical industry, in particular to the finishing rolling of the Morgan fifth generation high-speed wire rod mill, and discloses a Φ22.3 mm round steel finished product rack rolling guide roller. BACKGROUND

[0002] With the rapid development of the national economy in China, the metal product industry has made certain progress in both capacity and products, and more requirements are put forward for the raw materials required by the industry, mainly as follows: 1. In order to be more economical and convenient, the demand for non-standard specifications of wire rods increases. 2. The single roll weight of wire rods is expected to be improved on the basis of the current situation. 3. The demand for high-quality steel and alloy steel increases significantly. As the mainstream wire rod mill for wire rod production in China, the Morgan fifth generation high-speed wire rod mill has a product outline of finished product ф5.5mm-ф20mm with 0.5mm increments, and the market demand for Φ22.3mm wire rod is large. However, many wire rod mills are limited by equipment level and process design and cannot produce Φ22.3mm wire rod. In order to meet the individual needs of users, it is necessary to design and produce Φ22.3mm wire rod, which not only widens the product outline but also reserves technical capabilities. When developing the Φ22.3mm product of the Morgan fifth generation high-speed wire rod mill, the design of the finished product rack rolling guide roller is a key link. The finished product rack rolling guide roller rotates at high speed with the rolled piece, and its hole type width, depth and curvature as well as the opening degree of the two guide rollers are the key to ensure smooth production. SUMMARY

[0003] The purpose of the present application is to provide a Φ22.3mm round steel finished product rack rolling guide roller, which breaks through the original design specifications of the Morgan fifth generation high-speed wire rod mill and provides necessary technical guarantee for widening the product outline of the production line.

[0004] To solve the above technical problems, the present application adopts the following technical scheme:

[0005] The Φ22.3mm round steel finished product rack rolling guide roller of the present application comprises:

[0006] 1) The Ф22.3mm round steel specification finished product rack rolling guide roller refers to the ф22.0mm finished product rack rolling guide roller, and the guide roller type adopts the 35 series;

[0007] 2) The guide roller hole type radius R value is the same as the finished product front rack roller ring R value, that is, R = 21.0mm;

[0008] 3) ф22.3mm round steel specification finished product frame rolling guide guide roller bearing adopts 6202 rolling bearing;

[0009] 4) ф22.3mm specification finished product frame rolling guide guide roller parameters as follows table:

[0010]

[0011] Further, the guide roller material is selected as 1Cr13.

[0012] Further, the guide roller material is selected as 0Cr18Ni4Cu4Nb.

[0013] Compared with the prior art, the beneficial technical effects of the present application are:

[0014] Through the design of a high-speed wire rod mill for producing ф22.3mm specification finished product frame rolling guide guide roller, the Morgan fifth generation high-speed wire rod mill can produce ф22.3mm specification wire rod that meets the national standard requirements, which broadens the product outline of the Morgan fifth generation high-speed wire rod mill, meets the individualized needs of different downstream users, breaks through the design limit, provides a reference for the development of various types of units in the future, and creates considerable economic benefits for related enterprises. According to the annual production of 2000 tons of ф22.3mm specification finished product, and the profit of 350 yuan per ton of product compared with other standard specifications, the annual economic benefit is: 2000X350=70(10,000 yuan). BRIEF DESCRIPTION OF DRAWINGS
