Problems solved by technology

The existing water-piercing control process adopts the control method of turning on the cooling water one by one along the running direction of the finished product. The resistance of the wire rod in the entire water-piercing cooling line is getting bigger and bigger, and the head of the small-sized wire rod is not considered in the water tank When the body is subjected to the resistance of cooling water, it is easily disturbed, which increases the probability of bending and deformation, and then blocks the water-through pipe, causing production to stop

Embodiment

[0020] Embodiment: After the steel with a diameter of Φ10mm is formed by the finished rolling mill 1, the thrust of the finished rolling mill 1 pushes the wire 3 into the water-through cooler 2, and when entering each section of the water-through cooler 2, first turn on the water-through cooler 2 The control valve 4 at the end of the cooler 2 prevents the thread end of the wire 3 from being resisted by the cooling water sprayed by the control valve 4 when it enters the water-through cooler 2, and reversely opens the control valve 4 to the wire when the wire 3 advances. When going into the end of the water cooler 2, open the control valve 4 at the front end of the water cooler 2. After passing through the multi-section water cooler 2, the wire 3 is cooled to the required temperature. And the 3 parts of the wire rod head are not bent.

Abstract

The invention discloses a cooling device for a rolled high-speed wire rod and a method thereof. A water penetration cooling device is arranged on a finished product rack in the wire rod advancing direction; cooling water is torn in the inverted order in the wire rod advancing direction; the resistance to the wire rod head part is greatly reduced, the bending deformation possibility is reduced, and the frequency of blockage of water penetration pipelines is reduced, so that the influence to production is reduced.

Description

technical field [0001] The invention relates to the technical field of high-speed wire production, in particular to the field of cooling temperature control of high-speed wire finished products. Background technique [0002] In the production process of high-speed wire rod, in order to meet the required physical properties of the product, it is necessary to carry out water-through cooling control process on the finished product after rolling, and change the structure of the finished product to meet the required structure and physical properties of the product. The existing water-piercing control process adopts the control method of turning on the cooling water one by one along the running direction of the finished product. The resistance of the wire rod in the entire water-piercing cooling line is getting bigger and bigger, and the head of the small-sized wire rod is not considered in the water tank When the body is subjected to the resistance of cooling water, it is easily ...
