Description
Technical field
The present invention relates to the disjunctor processing method of a kind of chock plug and nozzle connection.
Background technology
The market Requirement Increases to large-scale steel ingot, ingot quality is required more and more higher simultaneously, requiring the harshest to gas content in steel, in atmospheric environment, casting process is unfavorable for reducing gas content in steel further, thus the mode that large-scale steel ingot uses vacuum pouring is poured into a mould.During vacuum pouring, stopper system is cast switch and note speed control system, controls switch and the note speed of vacuum pouring, and realizes Argon operation.Stopper system is mainly made up of stopper rod, chock plug, nozzle connection, sleeve brick.The applicant is former, and the chock plug of stopper uses pin with nozzle connection or threadeds.Chock plug uses pin to be connected with nozzle connection, and the gap after chock plug top is connected with nozzle connection must be filled with refractory clay, and refractory clay enters molten steel in casting process, stains molten steel, affects the degree of purity of molten steel.The chock plug of stopper is threadeded with nozzle connection employing, and chock plug is susceptible to come off in casting process, causes cast accident.
Summary of the invention
It is an object of the invention to for above-mentioned present situation, it is desirable to provide one is resistant to high-temperature molten steel and corrodes, and scour resistance is strong, it is ensured that molten steel is pure, is avoided that the disjunctor processing method of the adeciduate chock plug of chock plug and nozzle connection.
The implementation of the object of the invention is, chock plug and the disjunctor processing method of nozzle connection, specifically comprises the following steps that
1) cylinder rod iron is from the axial through nozzle hole in center, one end, axially bores Nozzle from spraying into through hole, goes out round platform at holes interface position car, and outer round platform bottom car goes out chamfering and forms bearing block, nozzle connection completion of processing；
2) the bottom centre position dress alignment pin of the mould of processing chock plug, alignment pin inserting step 1 by chock plug mould) nozzle connection processed inserts in Nozzle, magnalium carbonaceous refractory powder is put into chock plug mould from chock plug mould 4 upper part, by compressing chock plug, i.e. it is processed into the overall structure of chock plug and nozzle connection；
3) overall chock plug is after 100～120 DEG C of baking 24h, is rapidly heated to 400～500 DEG C of baking 24h, naturally cools to room temperature and come out of the stove, obtain the overall structure of chock plug and nozzle connection.
The alignment pin in chock plug mould of the present invention is used to insert in Nozzle, again magnalium carbonaceous refractory powder is put in chock plug mould by compressing disjunctor product, use and be not required between chock plug top of the present invention and nozzle connection fill refractory clay, refractory clay etc. will not be brought into be mingled with, its high temperature resistance molten steel corrodes, scour resistance is strong, it is ensured that the degree of purity of molten steel；One-shot forming is not required to threaded, it is to avoid metal threaded rack the problem that chock plug screw thread causes chock plug to come off in casting process because of expansion, can meet during large-scale vacuum ingot steel casting chock plug long-time immersion and adeciduate requirement in high-temperature molten steel.

Detailed description of the invention
The present invention is described in detail in detail with reference to the accompanying drawings.
With reference to Fig. 1,2, the present invention processing specifically comprise the following steps that
1) material is the through nozzle hole 1 that the cylinder rod iron of 2Cr13 a size of φ 40 × 190 axially bores φ 6 × 190 from center, one end, the Nozzle 3 of φ 10 × 110 is axially bored from through nozzle hole, the outer round platform of φ 40 × 20 is gone out at holes interface position car, outer round platform bottom car goes out 13 × 45 ° of chamferings and forms bearing block 2, and nozzle connection 8 processes.
2) the bottom centre position dress alignment pin 5 of the mould 4 of processing chock plug, alignment pin 5 is the round steel bar of φ 5 × 80.Alignment pin 5 inserting step 1 by chock plug mould 4) nozzle connection 8 processed inserts in Nozzle 3, must assure that nozzle connection 8 and chock plug mould 4 plan vertical during assembling.Magnalium carbonaceous refractory powder is put into chock plug mould from chock plug mould 4 upper part equivalent at twice, by compressing chock plug 7, is processed into overall chock plug；Described magnalium carbonaceous refractory powder is Al2O3:MgO:SiO2: the powder of C=70:12: 10:8.
3) overall chock plug is after 100～120 DEG C of baking 24h, is rapidly heated to 400～500 DEG C of baking 24h, naturally cools to room temperature and come out of the stove, obtain the overall structure of chock plug and nozzle connection.
Nozzle connection 8 is assemblied in alignment pin 5 from the upper end of chock plug mould 4, wherein, and is fixed on the top of chock plug mould 4；Magnalium carbonaceous refractory powder is added from twice equivalent of chock plug mould 4 upper part, after adding magnalium carbonaceous refractory powder 2.4kg for the first time, band φ 26 punch die press is pressed from chock plug mould 4 top, press stroke is 90mm for the first time, then second time adds 2.4kg magnalium carbonaceous refractory powder, carry out again suppressing global formation, natural Health preservation.
After natural Health preservation, the demoulding is overall chock plug 7；Then entirety chock plug 7 is toasted, after 100～120 DEG C of baking 24h, be rapidly heated to 400～500 DEG C of baking 24h, naturally cool to room temperature and come out of the stove.
The alignment pin in chock plug mould of the present invention is used to insert in Nozzle, again magnalium carbonaceous refractory powder is put in chock plug mould by compressing integral product, use and be not required between chock plug top of the present invention and nozzle connection fill refractory clay, refractory clay etc. will not be brought into be mingled with, its high temperature resistance molten steel corrodes, performance of flushing is strong, it is ensured that the degree of purity of molten steel；One-shot forming is not required to threaded, avoid owing to refractory material is different from temperature deformation in the case of metallic high temperature, metal threaded with engage between chock plug screw thread tighter, the metal threaded chock plug screw thread that racks because of expansion causes chock plug to come off in casting process, and during meeting large-scale vacuum ingot steel casting, chock plug soaks and adeciduate requirement in high-temperature molten steel for a long time.
