Abstract
The utility model discloses a quick plate blank change argon-blowing-type filling pipe end which belongs to the technical field of functional refractory material equipment. Particularly the utility model relates to a quick plate blank change argon-blowing-type filling pipe end. The quick plate blank change argon-blowing-type filling pipe end comprises a filling pipe end body and is characterized in that: the filling pipe end body has a split type structure; an upper end of the filling pipe end body is provided with a magnesium carbon layer and the lower end is provided with an aluminum carbon layer. The quick plate blank change argon-blowing-type filling pipe end has a split type structure. The aluminum carbon layer is provided at the lower end of the filling pipe end body, and the magnesium carbon layer is provided at the upper end. When a stopper contacts with the upper end repeatedly, abrasion of the upper end is prevented. The quick plate blank change argon-blowing-type filling pipe end further has the following advantages: improving wearing resistance and corrosion resistance, effectively controlling flow of molten steel, improving continuous casting level of the plate blank, preventing filling pipe end blockage of the plate blank, and obtaining a purpose of normal casting.
Description
Technical field
The utility model belongs to functional fire resisting material apparatus technical field, is specifically related to a kind of slab quick change Argon type filling pipe end.
Background technology
Tradition slab filling pipe end outer surface material is the aluminium carbonaceous, and molten steel flows through traditional slab filling pipe end stopper control, is transported to crystallizer from tundish.According to the requirement of strand pulling rate, with stopper molten steel is reached the purpose of controlling molten steel flow through filling pipe end, the variation of being poured into a mould steel grade simultaneously, especially aluminum killed steel, mouth of a river endoporus also can form the stifled stream of alundum (Al traditionally.Tradition slab filling pipe end and stopper contact portion are easy to be worn, and it is not tight to cause stopper to contact with traditional slab filling pipe end, the influx of uncontrollable molten steel, and influence is cast normally, does not reach the effect that the slab filling pipe end uses, and influences slab quality and service life.
Summary of the invention
The utility model technical problem to be solved provides a kind of slab quick change Argon type filling pipe end, can improve the wearability of filling pipe end end.
For solving the problems of the technologies described above; The technical scheme of the utility model is: a kind of slab quick change Argon type filling pipe end is provided; Comprise the filling pipe end body, it is characterized in that the filling pipe end body is a split-type structural, in filling pipe end body upper end the magnesium carbon-coating is set, the lower end is provided with the aluminium carbon-coating.
Lower end at the filling pipe end body is provided with pedestal, inlays the gas injection plug on pedestal top, offers injecting hole in the gas injection plug, in pedestal, offers the Argon passage, offers sealing ring in the pedestal bottom, and Argon passage two ends are connected with injecting hole and sealing ring respectively.
The beneficial effect of the utility model is:
1. the utility model is a split-type structural, in filling pipe end body upper end the magnesium carbon-coating is set, the lower end is provided with the aluminium carbon-coating, when stopper contacts with the upper end repeatedly; Can not make the upper end wearing and tearing; Improve its anti-wear performance and corrosion resistance, effectively control molten steel flow, improve the sheet billet continuous casting level; Prevent slab water slug suitable for reading, reach the purpose of normal cast.
2. the lower end of filling pipe end body is provided with pedestal; Inlay the gas injection plug on pedestal top; Offer injecting hole in the gas injection plug, in pedestal, offer the Argon passage, offer sealing ring in the pedestal bottom; Argon passage two ends are connected with injecting hole and sealing ring respectively, can guarantee airborne oxygen not can through and the immersion filling pipe end between the slit enter into filling pipe end.When argon pressure reached at 0.2-0.5MPa, throughput was even, can reach the effect of purify hot metal.

The specific embodiment
Below in conjunction with the accompanying drawing and the specific embodiment the utility model is described in further detail.
As shown in the figure, in the utility model, filling pipe end body 1 is a split-type structural, is divided into top and bottom, and the upper end is provided with magnesium carbon-coating 2, can improve the mar proof of the utility model port, increases the service life, and the lower end is provided with aluminium carbon-coating 3.
The lower end of filling pipe end body 1 is provided with pedestal 8; Inlay gas injection plug 6 on pedestal 8 tops, offer injecting hole 7 in the gas injection plug 6, in pedestal 8, offer Argon passage 4; Offer sealing ring 5 in pedestal 8 bottoms, Argon passage 4 two ends are connected with injecting hole 7 and sealing ring 5 respectively.
Slab quick change Argon type filling pipe end usually is used with submersed nozzle, and pedestal 8 links to each other with submersed nozzle, has the slit between the two, and airborne oxygen can enter in the filling pipe end through the slit, causes the interior molten steel generation secondary oxidation of filling pipe end.In order to address this problem, in injecting hole 7, inject argon gas, argon gas stream is discharged from sealing ring 5 through Argon passage 4, and airborne oxygen can not entered in the filling pipe end.Argon gas exists as a kind of protection gas, and when argon pressure reached at 0.2MPa, throughput was even, can reach the effect of purify hot metal, prevented the obstruction of filling pipe end simultaneously.
It is to be noted; Above-mentioned embodiment only is the utility model preferred embodiment; For those skilled in the art, under the prerequisite that meets the utility model operation principle, any be equal to or similar replacement all falls in the protection domain of the utility model.
Claims (2)
1. a slab quick change Argon type filling pipe end comprises the filling pipe end body, it is characterized in that the filling pipe end body is a split-type structural, in filling pipe end body upper end the magnesium carbon-coating is set, the lower end is provided with the aluminium carbon-coating.
2. according to the described a kind of slab quick change Argon type filling pipe end of claim 1; It is characterized in that pedestal being set in the lower end of filling pipe end body; Inlay the gas injection plug on pedestal top, offer injecting hole in the gas injection plug, in pedestal, offer the Argon passage; Offer sealing ring in the pedestal bottom, Argon passage two ends are connected with injecting hole and sealing ring respectively.
