Abstract
The present invention provides a kind of novel anhydrous stemming and preparation method thereof.The anhydrous stemming is by weight by following material composition：20~40 parts of Brown Alundum, 15~20 parts of carborundum, 10~15 parts of coke blacking, 10~15 parts of silicon nitride, 1~5 part of active oxidation aluminium powder, 5~10 parts of pyrophillite, 1~5 part of metal powder, 1~5 part of two silica flour, 2~8 parts of resin, 2~8 parts of silica flour, 15~25 parts of Carbores T60 bonding agents, 1~5 part of carburant.Anhydrous stemming of the present invention is not only environmentally friendly, and with the feature that coking intensity is high, sintering time is short, when anhydrous stemming is contacted with the breakage of blast furnace cooling stave or air port water collar, can moment coking, gap is blocked, the phenomenon of the iron mouthful splash caused by steam and coal gas blowby is efficiently solved, and no longer needs damping down to stop production, therefore the continuous production of blast furnace can be ensured.
Description
Technical field
The present invention relates to a kind of novel anhydrous stemming, belong to technical field of fire-resistant material preparation.
Background technology
With the long-term use of blast furnace, easily there is disrepair phenomenon in blast furnace cooling stave or air port water collar, and the breakage is not
Only resulted in water seepage and formed steam, but also can because formed gap and caused by blast furnace gas blowby.Due to blast furnace gas,
Steam can not be discharged, therefore had to enter and dispelled slag iron stream in iron mouth pore passage, so cause iron mouthful open after slag iron splash.
Iron mouthful splash, can not only bring pollution to surrounding environment, but also can bring serious potential safety hazard, that is, threaten stove
The safety of preceding equipment and the personal safety of stokehold workman.
At present, the method for administering iron mouthful splash be usually require blast furnace must damping down stops production and changes iron mouth, be so bound to
The continuous production of blast furnace has been had a strong impact on, and has virtually added production cost.
In order to overcome the shortcomings of above-mentioned improvement iron mouthful spray method, people worked out one kind can repair iron mouthful passage,
And can be as the daily anhydrous stemming for tapping a blast furnace and using, a kind of anhydrous stemming and its preparation as disclosed in patent 2014106633440
Method.But the anhydrous stemming its in actual use, have the following disadvantages：1st, gas permeability, scour resistance, erosion resisting, burning
Knot performance is undesirable, and elevated temperature strength is poor；2nd, due to component tar, causing that during use noxious material can be discharged, not only
Environment, and the health of harm operator are polluted, in addition the hard poor performance of quick-drying speed, stability is poor.
The content of the invention
It is an object of the invention to provide a kind of environmental-friendly and efficient novel anhydrous stemming and preparation method thereof.
Novel anhydrous stemming, by weight by following material composition：20~40 parts of Brown Alundum, 15~20 parts of carborundum,
10~15 parts of coke blacking, 10~15 parts of silicon nitride, 1~5 part of active oxidation aluminium powder, 5~10 parts of pyrophillite, 1~5 part of metal powder,
Two 1~5 part of silica flours, 2~8 parts of resin, 2~8 parts of silica flour, 15~25 parts of Carbores T60 bonding agents, 1~5 part of carburant,
5~10 parts of dolomite dust.
The preparation method of the novel anhydrous stemming, comprises the following steps：
(1) by the parts by weight take Brown Alundum, carborundum, coke blacking, silicon nitride, pyrophillite, two silica flours, silica flour,
Dolomite dust carried out in mixer it is dry-mixed, be well mixed after in 100~110 DEG C of environment carry out drying 20~30min, 45~
55 DEG C of constant temperature storages, obtain mixture A；
(2) active oxidation aluminium powder, metal powder are taken by the parts by weight, then adds resin while stirring, resin
Addition be desired amount of 50%~60%, mixture B is obtained after stirring；
(3) the mixture A, mixture B, the resin of surplus and Carbores T60 bonding agents are sufficiently stirred for,
The addition of Carbores T60 bonding agents is desired amount of 70%~80%, obtains mixture C；
(4) the Carbores T60 bonding agents of mixture C and surplus are stirred, from sample tap inspection by sampling horse summer value, made
The horse summer value control of stemming is obtained in 0.7-0.73MPa, qualified discharging, Ruo Maxia values are higher, need to add Carbores T60 combinations
Agent.
The present invention be using main component for aluminum oxide Brown Alundum as aggregate, innovation and, dolomite dust and Carbores
T60 bonding agents are combined, and are aided with carborundum, active oxidation aluminium powder, metal powder, carburant, resin, coke blacking, pyrophillite, quartz
Powder, silicon nitride, make anhydrous stemming of the present invention have following technique effect：
1st, anhydrous stemming of the present invention has the advantages that coking intensity is high, sintering time is short, when anhydrous stemming and blast furnace cooling
Wall or air port water collar breakage contact when, can moment coking, gap is blocked, and by anhydrous stemming itself tool
Good toughness, thermal shock resistance, the coefficient of expansion and the volume stability having, may be such that anhydrous stemming can firmly be attached to seam
In gap and have a style of one's own, and then efficiently solve the phenomenon of the iron mouthful splash caused by steam and coal gas blowby, and no longer need
Want damping down to stop production, therefore the continuous production of blast furnace can be ensured, can more be sent out in the case of particularly having leak in blast furnace taphole region
The rapid advantage of its coking is waved, the safe and reliable safety that ensure that iron mouthful belongs to efficient functional stemming；
2nd, in anhydrous stemming of the present invention, due to the use containing active oxidation aluminium powder, metal powder and resin, therefore improve
Activity, and then the associativity of Brown Alundum and Carbores T60 bonding agents is added, the coking capacity and volume to anhydrous stemming are steady
It is qualitative that there is good facilitation, for preferably protecting tapping hole, " mushroom-shaped " wall can be formed on the inside of tapping hole, is had
Effect extension iron mouthful depth, it is ensured that safety of tapping a blast furnace；
3rd, anhydrous stemming of the present invention has very superior high temperature resistant property and an erosive wear resistant performance, carburant it is reasonable
Use, not only overcome it is traditional because carborundum content is higher and produces sintering character it is poor the problem of, and more ensure that
Excellent elevated temperature strength, high corrosion resistance, scour resistance, meet large blast furnace and tap a blast furnace for a long time requirement, significantly drop reaming,
Reduce splash；
4th, anhydrous stemming of the present invention belongs to real environment-friendly highly efficient anhydrous stemming, is compared with traditional tar resin combination stemming
It is more environmentally friendly, strict environmental requirement is fully achieved, German Rui Jia house journals product is used for bonding agent, thoroughly takes leave of using burnt
Oil, the thick smoke of resin stemming, the content of its harmful substance benzo flower is 1st/40th of traditional stemming, hence it is evident that purification
Workman's is healthy before stokehold environment, more preferable protection stove, most harsh Environmental Protection at Steel Works standard is fully met, in environmental-protecting performance
With comprehensive beyond tradition tar resin combination stemming in erosion-resisting characteristics；
5th, anhydrous stemming of the present invention can be used as the daily normal stemming tapped a blast furnace, can act also as high dedicated for repairing
Stove cooling wall or the anhydrous stemming in air port water collar gap.
