Abstract
A device for cooling and removing phosphorus of a red steel ingot of a blooming mill belongs to the field of steel rolling and comprises a high-pressure water pump, an arc-shaped water through pipe and a straight-through water pipe, wherein the high-pressure water pump is respectively connected with the arc-shaped water through pipe and the straight-through water pipe; the arc-shaped water through pipes are positioned above the roller way and the red steel ingot, the straight water through pipes are positioned above the ground roller and below the red steel ingot, the arc-shaped water through pipes are provided with a plurality of nozzles at equal intervals, and the straight water through pipes are provided with 5 nozzles at equal intervals; the nozzle is a VK25-120-RD-4A nozzle. The utility model discloses can eliminate because the adhesion that the steel ingot heating formed is at the iron oxide phosphorus that the spindle body surface is difficult for droing, red steel ingot iron phosphorus adhesion difficult problem before having solved the blooming through using this device, guaranteed that red flat ingot is clean on the surface and has not had the foreign matter, reach and roll back finished product base excellent surface, stopped the production of waste product or salvage article. Further improves the product quality, reduces the production cost and increases the economic benefit.
Description
Technical Field
The invention belongs to the field of metallurgical steel rolling, and is mainly used for cooling and removing phosphorus of a 1000mm blooming mill ingot.
Background
After the steel ingot is heated at a high temperature in a soaking pit furnace, iron phosphorus oxide with the thickness of 3-5 mm can be formed on the surface of the steel ingot, no online dephosphorization equipment is arranged before the existing blooming mill, the iron phosphorus is adhered to the steel ingot and is not easy to fall off, the iron phosphorus is pressed into a steel body during rolling, slag inclusion and pit pressing are formed on the surface of a finished steel billet product, waste products or salvaged products are caused, the production cost is increased, and the benefit is reduced.
The cooling dephosphorization equipment is used by considering the uniformity and the strength of the cooling process, otherwise, the rolling defects such as squaring and the like are generated in the rolling process due to uneven extension, the angle and the pressure of a nozzle need to be continuously adjusted on site, and the final purpose is to ensure the dephosphorization effect and the cooling strength and the uniformity.
Disclosure of Invention
The invention aims to solve the problem of iron phosphorus adhesion before rolling of the red steel ingot, namely, the iron phosphorus of the red steel ingot before rolling is removed, the surface of a finished blank is qualified and excellent, and waste products or salvage products are avoided.
The technical scheme of the invention is as follows: a device for cooling and removing phosphorus of a red steel ingot of a blooming mill is characterized by comprising a high-pressure water pump, an arc-shaped water pipe and a straight-through water pipe, wherein the high-pressure water pump is respectively connected with the arc-shaped water pipe and the straight-through water pipe;
the arc water service pipe is located the roll table and the red steel ingot top, and the straight water service pipe is located above the ground roller and is located the below of red steel ingot, and the arc water service pipe equidistance sets up a plurality of nozzles, and 5 nozzles are installed to the straight water service pipe equidistance.
The nozzle is a VK25-120-RD-4A nozzle.
And the cooling and dephosphorization device is arranged on a receiving roller way of the blooming mill and is positioned above a 9 th ground roller and a 13 th ground roller, and the spraying length L is 3 meters.
The invention sprays the red steel ingot by high-pressure water to wash off the iron phosphorus adhered to the red steel ingot, overcomes the problem of iron phosphorus adhesion of the red steel ingot before rolling, and achieves the purposes of improving the surface quality of products and reducing the production cost.
The basic invention is proved by experiments of Shanxi Tai steel stainless steel Limited company that the surface qualification rate of the continuous casting axle steel reaches 97.72% (the qualification rate is 80% before the invention is adopted).
