Technical Field
The utility model relates to a rolling EDC spray set of wire rod belongs to EDC technical field.
Background
At present, most of domestic wire production enterprises adopt an air-cooling online cooling process when producing high-carbon steel wire products, and the defects of low cooling speed, uneven cooling and the like can result in low tensile property and poor strength and toughness of the products. In order to meet the technological requirements of deep processing of products, downstream wire product enterprises need to carry out lead bath quenching treatment on high-carbon steel wires, so that the production cost is increased, and the environment is polluted by using heavy metal lead.
In recent years, new online cooling technologies such as salt bath, subsonic wave and water bath have been developed in the european and american countries and japan in succession, and staged results have been achieved. Among them, the national center for metallurgy research in Belgian and the Swedish Mugerhama propose a water cooling (off-line) control technique, EDC for the first time. The technology has the characteristics of no pollution and high quality, can omit the subsequent lead bath heat treatment process, and is an ideal novel cooling treatment technology at present.
In the process of rolling the bridge cable steel XC95LS, the outlet water temperature of the wire after passing through the EDC is not uniform (the integral temperature phase difference is 80-100 ℃) due to the uneven cooling of the self-bordering point of the wire before entering the EDC, and the performance strength is very poor.

Detailed Description
The present invention will be described in further detail with reference to the following embodiments.
As shown in fig. 1, in the EDC spraying apparatus for wire rolling in this embodiment, spraying apparatuses are symmetrically disposed on both sides of an EDC inlet roller bed, and the spraying apparatuses respectively perform local cooling on a wire joint point before entering the EDC. The spraying device comprises a mounting plate 6, a nozzle 2 and a screw 7, wherein the front end of the mounting plate 6 is provided with the vertical nozzle 2, so that the water outlet direction of the nozzle 2 is downwards sprayed. The rear end of the mounting plate 6 is fixedly provided with a water pipe clamp, and the water pipe 4 is horizontally fixed in the water pipe clamp. The water outlet of the water pipe 4 is communicated with the nozzle 2, so that the cooling water flows to the nozzle 2 through the water pipe 4 and is vertically sprayed out. The screw 7 is vertically arranged, one end of the screw is welded on the fixed frame 8, the screw 7 is sleeved with the first nut 5, the mounting plate 6 is provided with a waist-shaped hole, and the waist-shaped hole is sleeved on the screw 7, so that the first nut 5 is arranged below the mounting plate 6; be equipped with second nut 3 above the mounting panel, and second nut 3 overlaps on screw rod 7, and two nuts and the equal threaded connection of screw rod 7 realize that two nuts paste tight mounting panel 6 upper surface and lower surface for mounting panel 6 is fixed on screw rod 7. Rotating first nut 5 and second nut 3 makes two nuts keep away from mounting panel 6 surface respectively, and screw rod 7 can adjust about in mounting panel 6, the position about, adjust to the position of needs after, through rotating first nut 5 and second nut 3 for first nut 5 and second nut 3 paste tight mounting panel 6 upper surface and lower surface once more, realize mounting panel 6 and screw rod 7 fixed connection, thereby changed 2 injection positions of nozzle.
An L-shaped baffle plate 1 is arranged above the nozzle 2, and the L-shaped baffle plate 1 is fixed on the mounting plate 6 to prevent the cooling water sprayed from the nozzle 2 from splashing.
