Abstract
The utility model relates to a water cooling device for casting of metal wire rods, which comprises a heat holding furnace (1), a through hole (2), a crystallizer (3), cooling water pipes (4) and guide rollers (5). The molten metal outflow through hole (2) is arranged on the side wall of the heat holding furnace (1), the crystallizer (3) used for crystallizing molten metal is arranged at an outlet of the through hole, at least two cooling water pipes (4) used for cooling a metal wire rod (6) are arranged at an outlet of the crystallizer and distributed on the upper side and the lower side of the metal wire rod (6). The water cooling device for casting of metal wire rods can realize water cooling of the upper side and the lower side of the primarily crystallized metal wire rod, and cool the periphery of the wire rod uniformly, thereby not only strengthening cooling effect, but reducing composition segregation degree greatly. In addition, the water cooling device for casting of the metal wire rods is simple in structure and easy to be popularized.
Description
Technical field
The utility model belongs to field of metal casting technology, and particularly a kind of metal wire rod continuous casting connects the water cooling plant that draws.
Background technology
In the metal wire rod casting process, point molten metal flow to crystallizer from the holding furnace via through holes, finishes preliminary crystallization in crystallizer; Be subjected to cold water cold by force then, fully coagulation forming; And then under guide wheel and the effect of traction unit, take-up one-tenth dish.In reality continuously or during semi-continuous casting produced, the existence of crossing cold effect easily caused the generation of the uneven crystalline polamer of melt.Promptly, the diffusion velocity of solute atoms in melt be less than rate of crystalline growth, and during alloy crystallization range broad, it is more that first crystallization crystal contains dystectic composition, it is more that the post crystallization crystal contains low-melting composition, causes the uneven distribution of chemical composition from the crystal grain edge to inside.The microsegregation degree is different because of alloy, though unavoidably can take measures to make it to alleviate.
Granted publication number discloses a kind of edge upward to the method and apparatus of cast metal silk, bonding jumper and metal tube for the Chinese patent of CN1086968C, this equipment comprise casting furnace and thus on the primary cooler that draws, and be positioned partially at casting nozzle in the primary cooler; In treating the direction of advance of cast product, after primary cooler, one after the other be provided with secondary cooling end that comprises direct water jet and the chute that is used to reclaim this water.Casting is to be 20～85 upwards to carry out when spending in the angle with respect to the casting furnace vertical axis; The cooling of cast article also directly sprays water on this cast article and cools off as secondary except cooling off for the first time in casting nozzle; The first cooling zone and the zone between the secondary cooling zone at cast product place are to be surrounded by protective gas.
But the said equipment is the same with existing conventional water cooling plant as shown in Figure 1, all is to adopt one-sided water pipe that material is cooled off, and cooling effect is relatively poor, and is special under the hot weather in summer, and intensity of cooling is difficult to guarantee.In addition, fully cooled off by cold water, and the below does not have to obtain equal cooling effect in time, very easily causes inhomogeneous crystallization, and then causes component segregation, influences product quality.
The utility model content
The purpose of this utility model is traditional metal wire rod casting water cooling plant is improved, the water-cooling structure that cool off simultaneously both sides about adopting, both guarantee the shower water intensity of cooling, reduced the possibility and the unfavorable effect of component segregation in the metallic crystal process again.
To achieve these goals, the technical solution of the utility model is as follows:
A kind of metal wire rod casting water cooling plant, comprise the holding furnace that molten metal is housed, have the through hole that allows molten metal flow out on the holding furnace sidewall, be provided with the crystallizer that makes the molten metal crystallization in the through hole exit, the exit of crystallizer is provided with the cooling water pipe that is used for the cool metal wire rod, described cooling water pipe is at least two, is distributed in the both sides up and down of metal wire rod.
Further, the cooling water pipe rear is provided with guide wheel on the metal wire rod direct of travel, promotes metal wire rod and moves forward, thereby guide its take-up one-tenth dish.Crystallizer can make point molten metal tentatively crystallize into metal wire rod, and the cooling water of the cooling water pipe that both sides distribute ejection can be realized the even cooling of metal wire rod both having strengthened cooling effect, greatly reduces the component segregation degree again.Described cooling water pipe can be connected with the cooling pond with water pump.
The beneficial effects of the utility model are: before metal wire rod passes through guide wheel, the metal wire rod of preliminary crystallization is realized both sides while water-cooled up and down, make wire rod evenly cooling all around both to have strengthened cooling effect, greatly reduce the component segregation degree again, and simple in structure, be easy to promote.
Description of drawings
Fig. 1 is the structural representation of existing a kind of common metal wire rod casting water cooling plant;
Fig. 2 is the structural representation of a kind of metal wire rod casting of the utility model water cooling plant embodiment.
The specific embodiment
Referring to accompanying drawing.The metal wire rod casting water cooling plant of present embodiment comprises holding furnace 1, through hole 2, crystallizer 3, cooling water pipe 4 and guide wheel 5, and cooling water pipe 4 is between crystallizer 3 and guide wheel 5.Wherein, holding furnace 1 is used to load point molten metal; The holding furnace sidewall has through hole 2, is used for the guide wire fused solution and flows out; The through hole exit is provided with crystallizer 3, can make the preliminary crystallization of molten metal; The exit of crystallizer 3 is provided with the cooling water pipe 4 of at least two spraying cooling water, and described cooling water pipe 4 is distributed in metal wire rod, and about in the of 6 both sides, respectively metal wire rod are sprayed cooling in both sides about in the of 6.Cooling water pipe 4 rears are provided with guide wheel 5 on the wire rod direct of travel, promote metal wire rod 6 and move forward, thereby guide its take-up one-tenth dish.Described cooling water pipe 4 can be connected with the cooling pond with water pump.
Crystallizer 3 can make point molten metal tentatively crystallize into metal wire rod 6, and the cooling water of cooling water pipe 4 ejections that both sides distribute can be realized the even cooling of metal wire rod 6 both having strengthened cooling effect, greatly reduces the component segregation degree again.
