Abstract

The utility model relates to a level continuous vacuum suction pouring apparatus which is suitable for being installed and used on the production line of level continuous casting. A cooling area and a vacuum zone are composed of a graphite mould, a lining sleeve, a casing, a vacuum shell, a vacuum tube, a water inlet tube, a water outlet pipe, etc. The purposes that the liquid alloy sucked in the maintaining furnace along the inner cavity of the graphite mould communicated with a vacuum system is solidified to continuous casting billets by the crystallization of the cooling zone, and the billets are drawn out by a level traction machine to obtain level continuous vacuum suction pouring are realized by using the vacuum value caused by the compressed air in the vacuum zone (suction force of the vacuum).

Description

Level continuous suction pouring apparatus

The utility model relates to a kind of horizontal continous vacuum absorbing and casting device, specifically a kind of being fitted on the horizontal casting production line, in order to produce the crystallization apparatus of non-ferrous metal and alloy strand thereof, be particularly suitable for utilizing the recovery waste materials to produce function admirable, the parison that quality is qualified.

At present, the horizontally continuously casting device of extensive use in industrial production is at its holding furnace one side configure generic crystallizer, utilizes the gravitation of horizontally tracting machine and the thermal stress in the holding furnace and carries out quantity-produced.Particularly under the situation in short supply, making full use of the old material of recovery and produce up-to-standard continuous casting moulding base with non-ferrous raw material in current production, is production, the key problem in technology of pendulum in face of enterprise.Yet, because it is many through the contained gas of the waste and old material of the recovery of repeatedly melt back, impurity, cause its tensile strength and mechanical performance very low, continuous casting parison defective with its production is many, performance is low, of poor quality, verified through exploration and practice, produce diameter at the light section bar below 6 millimeters particularly difficulty with it.

In view of above-mentioned prior art drawback that exists and the key problem in technology that needs to solve, the purpose of this utility model provides a kind of using under the liquid alloy situation with reclaiming waste materials melting suction casting, still can produce the horizontal continous vacuum absorbing and casting device of fine and closely woven, the colory continuous casting parison of crystallization on the existing level continuous casting line.

The technical scheme of the utility model takes following measure to realize: this horizontal continous vacuum absorbing and casting device is made up of members such as graphite mo(u)ld, lining, shell, vacuum connection tube, vacuum shell, sealing ring and water inlet pipe and water outlet pipes.The equipped cooling zone (I district) that forms a sealing of its lining and shell, the inner chamber of lining and an end stretch into the outer rim close-fitting of the graphite mo(u)ld in the holding furnace, are shaped on water inlet pipe and outlet pipe on case body; Member vacuum shell fixed configurations is on shell, and its peripheral solid welding, and the outer rim in heart strand hole is provided with special sealing ring therein makes it form a region of no pressure that communicates with the inner chamber of graphite mo(u)ld (II district), and vacuum shell is provided with the vacuum connection tube that links to each other with vavuum pump.

The suction pouring device that on the existing level continuous casting line, adopts the utility model to provide, because directly the liquid metal of drawing from holding furnace is to carry out continuous crystallisation under certain vacuum attraction, cooling condition, so can continuously produce organize fine and closely woven, grain refinement, pore are mingled with few strand, have solved the casting blank defect that utilizes when reclaiming old material and the diameter problems such as continuous casting difficulty at light section bar below 6 millimeters effectively.Like this, not only improve the quality and the performance thereof of strand, and greatly reduced consumption, saved the energy and expensive non-ferrous metal, improved the production efficiency of continuous casting.

Introduce design feature of the present utility model and operating position in detail below by the accompanying drawing illustrated embodiment.

Fig. 1 is this horizontal continous vacuum absorbing and casting device structural representation

Wherein: 1-holding furnace, 2-lining, 3-water inlet pipe, 4-vacuum connection tube, 5-sealing ring, 6-vacuum shell, 7-shell, 8-graphite mo(u)ld, 9-outlet pipe, 10-fixed lug.

Provide among the figure and illustrated entire infrastructure of the present utility model, it is made up of cooling zone (I district) and region of no pressure (II district) two large divisions, the inner chamber of lining 2 and an end stretch into the outer rim close-fitting of the graphite mo(u)ld 8 in the holding furnace 1, and with the equipped cooling zones that form these devices of shell 7, make the cooling effect by being located at water inlet pipe 3 on the shell 7 and outlet pipe 9 recirculated waters of various strand that continuous suction casting produces at this solidification and crystallization.Vacuum shell 6 fixed configurations are on shell outside the cooling zone 7, periphery welds fixing, and be provided with special sealing ring 5 in concentric strand hole, the center outer rim of itself and graphite mo(u)ld 8 inner chambers, thereby form a region of no pressure that connects with graphite mo(u)ld 8 inner chambers, also be provided with the vacuum connection tube 4 that links to each other with vavuum pump on the vacuum shell 6, the different vacuum values (pull of vacuum) of utilizing compressed air to cause in the region of no pressure suck liquid alloy in the holding furnace 1, the purpose of inhaling the casting mold base continuously with the vacuum that is up to the standard.

Whole absorbing and casting device is mounted on by fixed lug 10 on the holding furnace 1 of horizontal casting production line.

During work, different various of the section that will manufacture are in advance drawn bar penetrates graphite mo(u)ld 8 by strand hole in center on the vacuum shell 6 inner chamber earlier, enter then in the holding furnace 1 that fills with the liquid alloy that reclaims old material fusing, the vavuum pump that startup links to each other with vacuum connection tube 4, adjust the pin plug of vacuum meter, make and cause in the region of no pressure and required vacuum when reaching the different section strand and inhaling casting, meanwhile put cooling circulating water to the cooling zone by water inlet pipe 3, treat that the region of no pressure reaches when inhaling the casting vacuum values, under the effect of pull of vacuum, liquid alloy in the holding furnace 1 promptly is inhaled into and forms the continuous casting parison through the cooling zone crystallization along graphite mo(u)ld 8 inner chambers that are communicated with vacuum system in company with drawing bar, is gone out by the horizontally tracting power traction that starts.
