Problems solved by technology

[0008] The purpose of the present invention is to provide a cooling method and cooling device for a high-speed wire rolling mill Stelmore line. By installing a fan above the conveying roller table, the upper and lower air cooling of the wire is realized, the cooling speed is accelerated, and the cooling of the wire is more uniform at the same time. So as to solve the problem of uneven structure and mechanical properties of wire lap joints

Embodiment Construction

[0029] The present invention will be further described below with reference to the accompanying drawings and specific embodiments.

[0030] see figure 2 , a high-speed wire rolling mill Stelmore line cooling device, under the Stelmore line conveying roller table 1, a number of fans 2 are arranged in sequence along the direction of the conveying roller table 1, and on the Stelmore line conveying roller table 1 Along the direction of the conveying roller table 1 above, there are several fans 3 arranged in sequence. figure 2 Seven lower fans 2 and seven upper fans 3 are shown in the drawing, and the upper and lower fans 3 and 2 are in one-to-one correspondence, and the position along the transport roller way 1 direction is gradually improved. see figure 2 , the conveying roller table 1 forms an angle β with the horizontal line, and this angle exists in the prior art, and is generally 3° to 6°. The number of the upper fan 3 can be consistent with the number of the lower fan ...

Abstract

The invention relates to a cooling method and a cooling device for a stelmor wire of a high-speed wire mill. The cooling device for a stelmor wire of a high-speed wire mill adopts the structure that the lower side of a transport roller way of a stelmor wire is sequentially provided with a plurality of upper draught fans along the direction of the transport roller way, the upper side of the transport roller way of the stelmor wire is also sequentially provided with a plurality of lower draught fans along the direction of the transport roller way, the upper draught fans are arranged on a steel structural frame which can be conveyed in a hanging way, an air outlet of each upper draught fan is symmetrical to an air outlet of each lower draught fan relative to the transport roller way, and an included angle between the air direction of each upper draught fan and the transport roller way is equal to an included angle between the air direction of each lower draught fan and the transport roller way. The cooling method is applicable to the cooling device. Furthermore, additionally provided with the the draught fans on the transport roller way, the cooling device realizes the upper air cooling and the lower air cooling of the wires, increases the cooling speed, and causes the wires to be cooled more evenly, thereby the invention solves the problems of nonuniform wire contact-point structure and nonuniform mechanical property.

Description

technical field [0001] The invention relates to a cooling method and a cooling device for a STELMOR line of a high-speed wire rod rolling mill. Background technique [0002] At present, the Stelmore line is widely used in high-speed wire rod production lines. Its existing structure is that the wire rod is placed on the transport roller table, and the lower fan is installed under the transport roller table to cool the wire rod; Cover plate, the cover plate makes the temperature in the Stelmore line uniform. The existing cover plate is opened by fixing one end and lifting the other end, which is similar to the front cover of a car. There is a large space above the cover plate for the cover plate Lift up. The cover plate integrates the existing Stelmore line and maintains the inherent space. Taking a certain high-speed wire rod mill production line as an example, the cooling method of the existing Stelmore line is further explained: [0003] see figure 1 , The cooling secti...
