With the rapid development of national economy in China, the metal product industry has certain progress in both productivity and products, and also puts forward more requirements on raw materials required by the industry, which is mainly shown in the following steps: 1. the demand for large gauge wire rods increases. 2. The coil weight of the wire rod is expected to increase on the basis of the current situation. 3. The demand for high quality steel and alloy steel has increased significantly. The Morgan fifth generation high-speed wire rod rolling mill is taken as a mainstream rolling mill model for domestic wire rod production, the product outline is designed to be a finished product of a phi 5.5-phi 20 smooth surface wire rod, in order to meet the improvement of deep processing technology and the expansion of deep processing products of wire rod wire rods of downstream metal product enterprises, the market has a large demand on the wire rod with the phi 22mm specification, a plurality of wire rod rolling mills cannot produce due to the limitation of equipment level and process design, and a wire rod production line needs to be supplied to users after being coiled at high temperature through a large coiling production line, and the defects are that: 1. easily generate a large amount of secondary iron scale, low metal yield and difficult deep processing and acid pickling. 2. Long distance transportation is difficult. 3. Specialized unwind equipment is required for unwinding. Therefore, the wire rod with the diameter of 22mm is developed on a Morgan fifth-generation high-speed wire rolling mill production line, a good metallographic structure can be obtained through a controlled cooling process of an original rolling mill, the generation of secondary iron scale can be reduced as far as possible, the subsequent deep processing uncoiling, pickling and transportation are guaranteed, and the market prospect at home and abroad is good. The design of the finished hole pattern of phi 22 specification in the Morgan fifth generation high-speed wire rod rolling mill is also a key link therein.

SUMMERY OF THE UTILITY MODEL

In view of the above, in order to solve the defects existing in the background art, the utility model provides a finished roll ring for producing a wire rod with phi 22 specification by a high-speed wire rod rolling mill, and the wire rod with phi 22mm specification meeting the national standard requirement can be produced by using a high-speed wire rod rolling mill of the fifth generation of morgan, so that the product outline of the wire rod rolling mill of the fifth generation of morgan is widened, the requirements of different users are met, the design limit is broken through, and references are provided for the development of various types of units in the future.

In order to achieve the purpose, the utility model provides the following technical scheme:

a finished roll collar for producing a wire rod with the diameter of 22mm by a high-speed wire rod rolling mill comprises a pass arranged on a rolling groove, wherein the opening angle of the pass is 145 degrees, the radius is 11.5mm, the groove width is 22.3mm, and the groove depth is 10.5 mm.

Compared with the prior art, the utility model has the following beneficial effects:

1. the utility model provides a finished product roll collar for producing a wire rod with the phi 22 specification by using a Morgan five-generation high-speed wire rod rolling mill, which can produce the wire rod with the phi 22mm specification meeting the national standard requirement, widens the product outline of the Morgan five-generation wire rod rolling mill, meets the requirements of different users, breaks through the design limit, and provides reference for the development of various types of units in the future.

2. The finished product roll collar of the phi 22-specification wire rod produced by the high-speed wire rod rolling mill has remarkable economic benefit, 1 ten thousand tons of phi 22-specification finished products are produced annually, the profit of each ton is increased by 60 yuan compared with other specifications, and the annual benefit is 60 ten thousand yuan.
