Abstract
The utility model relates to a gas-water spraying device for continuous casting, which comprises an outer arc spray pipe, an inner arc spray pipe, a first lateral arc spray pipe, a second arc spray pipe, nozzles, nozzle holders and water inlets. The outer arc spray pipe, the inner arc spray pipe, the first lateral arc spray pipe and the secondary lateral arc spray pipe are symmetrically distributed around a work piece, one water inlet and the plurality of nozzles and nozzle holders are welded on each spray pipe, each spray pipe consists of a gas pipe and a water pipe, and the water inlet of each spray pipe is connected to the corresponding gas pipe, while the gas pipe and the water pipe are connected with the gas-water nozzles. The gas-water spraying device for continuous casting is simple in structure and convenient in use. The spray pipes are symmetrically distributed and include a plurality of sections, and spraying flow and angle of nozzles can be controlled separately, so that atomization is fine, water drops are small in diameter, and cooling is uniform. An outlet of each nozzle is large in diameter and not easy to block. The nozzles fewer in number evenly cover larger casting blank area, and thereby water is saved. The flow adjusting range is wide, and high-impact wide-angle jets are formed to achieve high cooling effect and uniformity for casting blanks. The gas-water spraying device for continuous casting is applicable to cooling various types of steel.
Description
Technical field
The utility model relates to a kind of strand spray cooling device, relates in particular to a kind of continuous casting and uses the air-water spray equipment.
Background technology
The strand that has the liquid heart comes out to get into secondary cooling zone from crystallizer, and cooling water is sprayed directly on on the strand further cooling and accomplishes the task of all solidifying.Therefore, slab quality and casting machine productivity are decided by distribution and control, the type of cooling of secondary intensity of cooling, cooling water, the level of two cold-zone equipment to a great extent.
Secondary cooling is to leaving the cooling of spraying water of crystallizer band liquid heart strand, so that strand solidifies fully, and controls casting blank surface temperature and evenly descends in the throwing direction.
Be to adopt directly to spray water strand is cooled off in two cold-zones, all heat radiation has direct influence to the distance between intensity of cooling, cooling water inflow, hydraulic pressure, water temperature, nozzle arrangements and layout, nozzle and strand etc. to strand.Should require to confirm reasonable cooling system according to steel grade and section.
The casting blank shell thickness that pulls out from crystallizer increases in two cold-zones gradually, and just having left crystallizer is that the base shell is thinner, and it is big that injection flow rate is wanted, so that the base shell thickens rapidly.Along with strand moves in two cold-zones, shell thickness increases, and injection flow rate should reduce gradually, and cooling length strengthens gradually.Therefore, be divided into some cooling sections to two cold-zones, each cooling section carries out water yield control separately, and work-piece cools effect and quality are seemed to be even more important.
The utility model content
The utility model for overcome the above problems provide a kind of simple in structure, the air water atomizing effect is good, continuous casting that impulsive force is high is used the air-water spray equipment.
The technical scheme of the utility model is: comprise outer arc shower, inner arc shower, side arc shower one, side arc shower two, nozzle, nozzle carrier and water inlet; Described outer arc shower, inner arc shower, side arc shower one, side arc shower two are symmetrically distributed in around the workpiece; Be welded with water inlet and plurality of nozzles seat, nozzle on the described every shower; Described every shower is made up of tracheae and water pipe; Water inlet is connected on the tracheae, and described tracheae and water pipe are connected on the air-water nozzle.
The utility model is simple in structure, easy to use, and shower is symmetrically distributed and is divided into plurality of sections and can control nozzle respectively and spray corresponding flow and angle, and water atomization is good, and drop diameter is little, and cooling evenly; The jet expansion diameter is big, is difficult for stopping up; Nozzle quantity is few, evenly covers bigger strand area, using water wisely; Flow adjustment range is big, the wide angle stream thigh of high impact forces, and to reach cooling effect and the uniformity coefficient very high to strand, the utility model is applicable to the cooling of all steel grades.
