Stelmo line gas spray cooling device and method for high-speed wire rod mill

Abstract

The invention simultaneously solves building the contact organization, the performance is uneven question. The invention has provides a kind of gas spray cooling system and the method, namely after the spinning machine, style touches in front of the air blower a section of air cooled table place above, two sides symmetrical establishes the gas spray chiller, first builds above the contact from the coil, key to builds the contact to leave the atomization to cool, then style touches the forced-air cooling line again from the underneath forced-air cooling, and uses the' good spirit installment concentratly blowing the contact place. The intensity difference between the line material build contact through the gas spray cooling system and the no build contact is fall to 5~7MPa; The overall intensity of the line material may enhance 20~25MPa; Improves the surface quality; Simultaneously decreases the ambient temperature, improves the operating environment.

Description

technical field [0001] The invention relates to equipment and methods for metal pressure processing, in particular to an air mist cooling device on the Stelmore cooling line of a wire rolling mill and its use method. Background technique [0002] When the high-speed wire rod rolling mill is rolling the wire rod, the wire rod needs to be coiled by the laying machine, and then flattened on the conveying roller table to be transported forward, and the wire rod is forced to be blown and cooled by the array of fans under the roller table. By changing the number of fans , The air volume distribution of each fan and the running speed of the roller table are used to adjust the cooling intensity of the coil, so that the wire rods of different steel types and diameters can obtain the required structure and performance. This is the traditional Stelmore controlled cooling line. [0003] Steyrmore wire can be divided into standard type, delayed cooling type and forced cooling type accord...

Problems solved by technology

[0004] The invention provides an air mist cooling device and method, that is, above a section of air-cooled roller table in front of the Stelmore blower after the laying machine, the air mist coolers are symmetrically arranged on both sides, and the air mist coolers are arranged firstly from above the lap joint point of the coil. , focusing on spraying and cooling at the overlapping point, and then the Stelmore air-cooled line is air-cooled from below, and using the "Karling device" to focus on blowing at the overlapping point, so that the Stelmore line can be improved Solve the problem of lap joint structure and uneven performance while cooling the strength
