Abstract
The invention discloses a preparation method of a waste magnesia carbon brick black smearing material which is prepared on the basis of tundish continuous pouring time, environment temperature and environmental protection use requirement, waste magnesia carbon bricks and forsterite are taken as main raw materials, the rational utilization and the cyclic utilization of the resource are realized, and the cost is also reduced; besides, the product construction is convenient, the construction body structure is compact, and no hazardous gas is discharged.
Description
Technical field
The present invention relates to the black coating preparation method of waste magnesia carbon brick.
Background technology
At present: the coating kind is a lot, and performance difference is very large, generally adopt magnesia and calcium magnesia sand, etc. for main raw material.These raw materials all belong to the high energy consumption product, and resource is day by day exhausted, and price is year improve then also.Coating is not on the market often paid close attention to the whether economical rationality of coupling between performance and concrete application conditions, there is " ability " waste of " wasting one's talent on a petty job " formula, leave excessive factor of assurance in the material configuration selection, cause certain function to have more than needed and waste of material.
Summary of the invention
Technical problem to be solved by this invention just is to provide the black coating preparation method of a kind of waste magnesia carbon brick, reduces production costs, and improves product competitiveness.
For solving the problems of the technologies described above, the present invention adopts following technical scheme: a kind of waste magnesia carbon brick is deceived the coating preparation method, comprises the following steps successively:
A) block waste magnesia carbon brick is broken into to macrobead with jaw crusher;
B) with roller crusher, macrobead being pulverized is the small-particle of particle diameter 0～3mm;
C) the part small-particle is finely ground into to the fine powder that particle diameter is 0.088mm with ball mill;
D) small-particle is sieved by the particle diameter difference, got the small-particle of 0～1mm particle diameter: 15wt～18%; The small-particle of 1～3mm particle diameter: 25～28wt%;
E) get the fine powder of 0.088mm particle diameter: 5～9wt%;
F) block forsterite is broken into to macrobead with jaw crusher;
G) with roller crusher, macrobead is ground into to the small-particle that particle diameter is 0～3mm;
H) small-particle is sieved by the particle diameter difference, got the small-particle of 0～1mm particle diameter: 8～10wt%; The small-particle of 1～3mm particle diameter: 10～15wt%;
I) the part small-particle is finely ground into to the fine powder that particle diameter is 0.088mm with ball mill;
J) get the fine powder of 0.088mm particle diameter: 12～15wt%;
K) take batching and carry out the wedding agent pre-mixing, the mass percent that wedding agent accounts for the black coating gross weight of waste magnesia carbon brick is 0.08-0.12wt%, and batching is by mass percentage: SiO:58.8wt%; Tripoly phosphate sodium STPP: 3.53wt%; Calcium lignin sulphonate: 2.35wt%; A-Al
2o
3: 23.5wt%; CA-70 cement: 11.82wt%; Pour above-mentioned batching into the forced stirrer stirring and carry out pre-mixing in 50～60 minutes, be delivered to mixing system after pre-mixing;
L) the disregard message paper of recovery is dropped in pulverizer and is ground into the newspaper fiber;
M) by d) waste magnesia carbon brick small-particle, e in step) waste magnesia carbon brick fine powder h in step) useless peridotites small-particle, j in step) useless peridotites fine powder in step utilizes conveying belt to be sent in the Preblend system PBS tank together, and batch mixing was delivered to mixing system after 6～8 minutes;
N) be equipped with k in mixing system) step and m) after the material carried in step, then add 1) the newspaper fiber of 0.7～1.0wt% in step, stir in mixing system and carry out packing after 5～9 minutes and obtain the coating finished product.
Preferably, described k) in step, churning time is 55 minutes; M) in step, mixing time is 7 minutes; N) in step, churning time is 8 minutes.
The black coating of carbon brick of the present invention is to develop on the basis according to tundish continuous pouring time, envrionment temperature, environmental protection service requirements, it take waste magnesia carbon brick, forsterite is main raw material, realize reasonable utilization, the recycle of resource, also reduced cost;
In addition, product easy construction of the present invention, the construction body structure closely, does not discharge toxic and harmful; When it is smeared, adhesion property is good, do not return, fall to caving in, do not stick trowel, the construction any surface finish, because in formula, not adding harmful chemical, the healthy factor that also just can not endanger the site operation personnel, because peridotites has aquation not, characteristics that chemical stability is high, in drying, bake process, shrink very little, tundish surface crackle after baking is very little and seldom, therefore the middle low temperature intensity of body of constructing is higher, in addition also unlike the low-grade MgO-CaO matter coating that adds a unprocessed dolomite and Wingdale material material because discharging a large amount of CO
2gas and peeling occurs, peel off, explosion even efflorescence and the phenomenon that collapses; Be no matter construction or spreading property all with market on like product suitable.
And, product performance of the present invention are better than the coating product that magnesia or magnesium calcium are raw material, the black coating of waste magnesia carbon brick can bear the continuous pouring high-temperature molten steel of 24 hours (1550～1650 ℃) erosion, wash away,, normal temperature and permanent layer have good cohesiveness, product to have slag resistance, antistripping, scour resistance, oxidation-resistance and anti-erosion.
In a word, the present invention has reduced cost, remarkable in economical benefits, the waste magnesia carbon brick cost is about 400 yuan/tons, approximately 500 yuan/tons of forsterite costs, approximately 1200 yuan/tons of magnesia market prices, production cost by the black coating of waste magnesia carbon brick per ton reduces costs 800 yuan of calculating than the magnesia coating, to produce 4000 tons of calculating per year, production cost reduces approximately 3,200,000 every year, current iron and steel enterprise generally implements functionalization and contracts, reduce ton steel cost, increasing economic efficiency is the common objective of contractor and steelworks, this has not only brought good economic benefit for our factory, improved again the market competitiveness of the black coating of waste magnesia carbon brick simultaneously.
