Abstract
What the present invention relates to is magnesite refractory slurry, and it is main raw material with magnesia, is wedding agent with dried shape sal epsom, and allocates a spot of admixture into and add water modulation and form.This mud has higher normal temperature and high temperature cohesive strength and good application property, and blending process is simple, easy to use.Be applicable to and build steel melting furnace, cement kiln, non-ferrous smelting furnace and other various high temperature kilns refractory product by laying bricks or stones with magnesia, magnesium chromium matter and magnalium matter liner.
Description
The invention belongs to a kind of magnesite refractory, is to build the good magnesite refractory slurry that magnesia, magnesium chromium matter and refractory magnesia-alumina goods are used by laying bricks or stones.
The globality of, magnesium chromium matter magnesia in high temperature kiln and the Thermal Equipment and the bricking of magnalium matter for guaranteeing, extending furnace lining life reaches synchronously mortar joint and liner life-span, and the possess skills magnesite refractory slurry of excellent property of development is that use value is arranged very much.The magnesite refractory slurry of the JF-PB that the VF that West Germany Di Deere ﹠ Co. produces, Osaka, Japan ceramic industry company produce and three kinds of trades mark of MGA-90 of Japan all is more advanced, therefore in smeltery, the eighties Guixi in mid-term and Shanghai Bao Steel, introduce in a large number, be used to build by laying bricks or stones the magnesium chromium matter working lining of copper smelting furnace and RH refining furnace as supporting mud.
Learn that according to object test result and scene use it is wedding agent that the magnesia mud of West Germany VF adopts single liquid sulfuric acid magnesium, all very inconvenient in preparation, packing, transportation and use, and also the mud cohesive strength is not high, and wedding agent is difficult to preserve; The magnesia mud of JT-PB of Japan, adopting alkaline powdery water glass is wedding agent, this wedding agent not only has the strong impulse flavor, and is big to the personnel's of building by laying bricks or stones skin corrodibility, and use temperature is lower; The normal temperature of the magnesia mud of the MGA-90 trade mark and high temperature cohesive strength are all very low.The object test of these three kinds of magnesite refractory slurries the results are shown in table 1.
The objective of the invention is to make that a kind of production cost is low, blending process is simple, be easy to preserve, easy to use, cohesive strength is high, workability is good, is applicable to magnesia, the magnesium chromium matter of external refining stove that masonry cement kiln, non-ferrous smelting furnace and working temperature are higher and other various Thermal Equipments and the magnesite refractory slurry that magnalium matter liner is used.
Magnesite refractory slurry provided by the present invention is to be raw material with magnesia or useless magnesia brick (magnesia brick produce in waste product), adopting dried shape sal epsom is wedding agent, blending process and packing and transport condition have been simplified greatly, make production cost reduce, preserve easily, and overcome that alkaline powdery water glass pungent taste is big, corrodibility is forced with the lower shortcoming of temperature.Allocate a spot of composite additive (comprise that polyphosphoric acid is received, white carbon black, carboxymethyl cellulose and dextrin, sulfonated lignin) into, to play reinforcement, to help sintering, water conservation and plastification, thereby improved mud cohesive strength, improved building by laying bricks or stones property, make this mud workability good, do not trickle, do not precipitate not dehydration, make qualified mortar joint easily, guarantee the globality of furnace lining in building the back by laying bricks or stones and using, prolonged lining life.
Import magnesite refractory slurry object test is table 1 as a result
Main points of the present invention be with the magnesia powder of 100 parts (weight) (＜0.088mm) and the compound additive of the dried shape sal epsom of 2.5～24 parts (weight) and 0.5～5.0 part (weight) (contain that polyphosphoric acid is received, white carbon black, carboxymethyl cellulose, dextrin, sulfonated lignin, get wherein three kinds) add water after mixing and be modulated into mud and use.
Embodiment: (1) (2) (3)
Magnesia powder (＜0.88mm), part 100 100 100
Dried shape sal epsom, part 14 12 18
Composite additive, part 3.0 2.5 2.5
Composite additive contains that (1) polyphosphoric acid is received, white carbon black, carboxymethyl cellulose.
(2) carboxymethyl cellulose, white carbon black, dextrin.
(3) sodium polyphosphate, white carbon black, sulfonated lignin.
The technical feature table 2 of invention magnesite refractory slurry
The technical feature of magnesite refractory slurry of the present invention is listed in table 2.This mud uses on cement rotary kiln, regenerator chamber of glass kiln, hyperthermia tunnel Kiln, is subjected to the consistent favorable comment of user, gets on copper smelting furnace for West Germany VF and the magnesia mud of Japanese JT-PB board, and its building by laying bricks or stones property and usability are better than import mud.Be used for integral body and build pre-assembling RH refining furnace magnesium chromium matter soaking tub by laying bricks or stones.The soaking tub of building by laying bricks or stones with this mud integral body through long-distance transport, when slinging upset not decylization, do not fall apart.Soaking tub is after using 119 times on the 300tRH stove, and mud ash seam still bonds well when removing because of other reason, does not have obvious etch phenomenon.
Claims (3)
1, a kind of magnesite refractory slurry, be mainly used in magnesia, the magnesium chromium matter and the refractory magnesia-alumina goods of building various high temperature kilns and Thermal Equipment by laying bricks or stones, it is to be refractory aggregate with magnesia powder or useless magnesia brick powder, it is characterized in that being is wedding agent with dried shape sal epsom, mixture with sodium polyphosphate, white carbon black, carboxymethyl cellulose, dextrin, sulfonated lignin is an additive, and it is formulated to add water.
2, magnesite refractory slurry according to claim 1 is characterized in that the weight proportion of each component is as follows:
Magnesia powder (＜0.088mm) 100 parts
2.5～24 parts in dried shape sal epsom
0.5～5.0 part of composite additive
3, composite additive according to claim 1 and 2 is characterized in that getting wherein three kinds of formations from sodium polyphosphate, white carbon black, carboxymethyl cellulose, dextrin and sulfonated lignin.
