Abstract
The invention relates to an integral type stopper capable of controlling inflow gas, comprising a stopper body, an inner cavity and a gas exhaust port, wherein the inner cavity is positioned in the stopper body, the gas exhaust port is positioned on the tail end of the stopper body, and the inner cavity and the gas exhaust port are communicated and connected by a gas passage. The integral type stopper is characterized in that one end in the inner cavity positioned on the gas passage is provided with a gas inlet column which upwards extends and is over the bottom end of the inner cavity, and the gas passage upwards extends to an opening on the top end of the gas inlet column and is communicated with the inner cavity; an annular hollow cavity is formed between the outer wall of the gas inlet column and the inner wall of the inner cavity; and the gas inlet column and the stopper body form a whole body. In the invention, the gas inlet column fully protrudes above the bottom end of the inner cavity at an inlet of the passage so as to prevent particles and dust from entering the inlet of the passage, is formed by integral pressing in a mould when the stopper is formed, and has good integrity, abrasion resistance of materials, low air permeability and good hot vibration property.
Description
Technical field
The present invention relates to a kind ofly be used to control melted material and pass the device that submersed nozzle flows from container, especially a kind of fire-resistant controllable flow is gone into the integral type stopper of gas.
Background technology
At present, stopper is elongated open tubular column structure, and circular or conical stopper head are arranged in the bottom, be applicable to the venturi that inserts corresponding discharge geat, and stopper comprises the jockey of definite shape in the upper end, so that stopper is fixed on the outside rising structure, thereby control is flowed.Stopper is widely used in the control motlten metal and takes advantage of the container of fused solution from being installed in dress, for example control motlten metal and discharge, be usually used in making steel to be poured in the water-cooled mould via geat and refractory brick cover youngster by opening in the tundish bottom from the geat of the bottom of casting ladle or tundish.
In continuous casting is handled, use is injected into the quality that gas below the stopper can obviously help the metal cast, can inject such as inert gases such as argon gas or nitrogen, so that reduce the problem that causes because of the accumulation of aluminium oxide and obstruction, also help to remove cured product near the outlet, usually, stopper provides internal chamber, this internal chamber at one end is connected with compressed air source unit, is connected with gas discharge outlet at the other end.
The patent No. provides a kind of being used for reliably to carry out the stopper that gas injects for 02811692.5 Chinese patent, and it comprises the stopper body, and this stopper body has internal chamber and gas discharge outlet; The hole that internal chamber is linked to each other with gas discharge outlet; Caliberating device is arranged in this hole so that the throttling path to be provided, and this stopper is characterised in that: this caliberating device comprises bar, and this bar has at least one along its axially extended gas passage, and this gas passage has a uniform section, so that predetermined flow resistance is provided.
Yet, above-mentioned stopper complex structure, the bar of the caliberating device of this stopper separates with the stopper body, must insert in the stopper body the also necessary and supporting use of seal in the latter stage that the manufacturing of stopper is handled, increased the possibility leakage point, the making of this bar and processing are very harsh to raw material and precision, and not only cost is very high, and machining period increases; In addition, seal is very easily aging under worst hot case, breaks, and directly influences the sealing property between bar and the stopper body, has not only increased cost of manufacture, more makes to can not get effective guarantee service life.Though, the bar of mentioning in the above-mentioned patent can be changed, regulate according to different stopper bodies, but often can not effectively satisfy the index of stability and reliability, and the gas discharge outlet of stopper still size is bigger than normal, the Compressed Gas of stopper inner chamber extremely disperses when gas discharge outlet is discharged, and does not concentrate.Sprue gate in the bottom is stopped up owing to the aluminium oxide accumulation is easy, and simultaneously, the shortcoming of this structure also has, and has impurity to enter in the inflow process of gas, stops up gas discharge outlet easily, is difficult to satisfied actual use needs.
Summary of the invention
The object of the invention provides the integral type stopper that a kind of controllable flow is gone into gas, blows place's aluminium oxide deposit by the monoblock type gas inlet column that is higher than the internal chamber bottom being set in the internal chamber of stopper, reaching, and keeps the unobstructed effect at sprue gate.
Technical scheme of the present invention is:
A kind of controllable flow is gone into the integral type stopper of gas, comprise the stopper body, be positioned at the intrinsic internal chamber of stopper, be positioned at the gas discharge outlet of stopper body tip, internal chamber is connected by gas passage with gas discharge outlet, be positioned at gas passage one end in the described internal chamber and be provided with the gas inlet column that extends upward and exceed the internal chamber bottom, gas passage extends upwardly to gas inlet column top end opening place, and is communicated with internal chamber; Form toroidal cavity between the outer wall of gas inlet column and the inwall of internal chamber; Gas inlet column and stopper body are an integral body.
Described gas passage is one section isodiametric tubular conduit or waney tapered channel or waney step passage from gas inlet column top end opening place to gas discharge outlet.
Described gas inlet column exceeds the height H of internal chamber bottom more than or equal to 10 millimeters.
The diameter of described gas passage is 0.1 millimeter to 5 millimeters.
The invention has the beneficial effects as follows:
Gas inlet column of the present invention is a monolithic construction, makes with this body by integral forming of stopper, has not only reduced parts, and one-body molded, and is firm reliable.Overcome and existingly controlled the mode that air-flow enters by increasing bar, with low cost, stablize durable.
Simultaneously, this gas feed rod structure is fully to protrude above internal chamber bottom, channel entrance place, to avoid particulate, the import of dust admission passage, this structure be when stopper is shaped in mould one compacting form, good integrity, material resistance to wears, air penetrability is low, and shaking property of heat is good.Can prevent gas in passage by the time reveal, reach the demarcation effect.
Important improvement of the present invention also is to be communicated with internal chamber and gas discharge outlet by long and narrow gas passage, the diameter of gas passage becomes thinner, increased the gas pressure that blows out from gas discharge outlet, and, because the gas discharge outlet size of stopper of the present invention is along with the gas passage size diminishes significantly, make that the Compressed Gas of stopper inner chamber is very concentrated when gas discharge outlet is discharged, form the bigger and concentrated little gas column of pressure at gas discharge outlet, can apply bigger impulsive force to the aluminium oxide deposit, the aluminium oxide deposit smashed break up, reach effective blowing aluminium oxide deposit, keep the unobstructed effect in sprue gate.
