Abstract
The invention provides boric sludge fire resistant ceramsites, relates to a fire resistant ceramsite aggregate formed by taking boric sludge as a main raw material. The boric sludge fire resistant ceramsites are invented mainly to solve the problem that at present, the boric sludge occupies a vast area and causes environmental pollution, the problem that the conventional boric sludge ceramsites is poor in high temperature resistance and the like. The boric sludge fire resistant ceramsites are prepared form the following raw materials in percentage by volume: 60 to 75 percent of boric sludge, 20 to 30 percent of magnesium slag, and 5 to 10 percent of bonding agent. The production method comprises the following steps of: grinding all raw materials, mixing the ground raw materials and adding water; granulating the mixture by a granulator; and baking the granules in a rotary kiln to obtain the boric sludge fire resistant ceramsites. The boric sludge fire resistant ceramsites have the advantages of replacing clay ceramsite and high-aluminum ceramsite, prolonging the service life of a hearth when used for building the hearth and reducing the building cost of the hearth and producing various fire resistant concrete, fire resistant building blocks, fire resistant filling materials and the like; and the boric sludge fire resistant ceramsites also solve the problems that the boric sludge occupies a vast area as well as causes environmental pollution and also have quite obvious social benefits.
Description
Technical field:
The present invention relates to boron mud is a kind of aggregate---the fire resistant ceramsites that main raw material is made.Be mainly used in that boiler is built by laying bricks or stones, the Thermal Equipment insulation handles or does fire-resistant stopping composition, refractory block etc.
Background technology:
Boron mud is to produce the waste residue that borax is discharged, and particularly Liaoning Province is annual produces a large amount of boron mud that borax discharges and not only taken a large amount of soils but also contaminate environment in China; On the other hand, need a large amount of refractory aggregates on the industrial production at present, and existing boron mud ceramsite resistance to elevated temperatures is poor, can only tolerate the temperature about 900 ℃, does not often satisfy the needs of producing.
Summary of the invention:
It is the good boric sludge fire resistant ceramsites of resistance to elevated temperatures of main material production with boron mud that technical problem to be solved by this invention provides a kind of.
The object of the present invention is achieved like this: produce the used raw material of boric sludge fire resistant ceramsites and comprise boron mud, magnesium slag, binding agent.The volume percent that various raw material consumptions account for the raw material total amount is: boron mud accounts for that 75%-60%, magnesium slag account for 20%-30%, binding agent accounts for 5%-10%.Described binding agent can be wilkinite, diatomite, limestone powder, magnesia, fireclay, both can be wherein any, also can be wherein several combination arbitrarily.
Production method: various raw material pulverizing are mixed, add water,, fire with rotary kiln then and form with balling-up mechanism ball.
The described concrete grammar of firing with rotary kiln is: starting material are after mixing balling-up, the rotary kiln baking of making a gift to someone, the limit adds the waterside and carries out bottom blowing in the roasting process, and adjusts flame, and ball is burnt to normalizing, reach 800-1200 ℃, cross about 25 minutes sintering and finish, the first one-step forming of haydite this moment can be seen the Solid solution of haydite light from kilneye, enter the expanded stage this moment, when Solid solution when going out 2 meters of kilneye, combustion-supporting sprays coal dust, coal dust acutely burns, temperature can reach 1250-1700 ℃, and generation high temperature, hyperbaric environment, Solid solution begins expanded, kiln discharge after 5-6 minute, obtain lightweight after the cooling, porous is spherical to gather materials, i.e. boric sludge fire resistant ceramsites.
Advantage of the present invention is: can replace leca, high alumina haydite, be used for boiler and build by laying bricks or stones and can improve burner hearth work-ing life, reduce burner hearth and build cost by laying bricks or stones, can also utilize this haydite to prepare various refractory concretes, refractory block, fire-resistant stopping composition etc.; The present invention has also solved boron mud simultaneously takes up an area of and problem of environment pollution caused, and its social benefit is also fairly obvious.
Embodiment:
Produce the used raw material of boric sludge fire resistant ceramsites and comprise boron mud, magnesium slag, binding agent.The volume percent that various raw material consumptions account for the raw material total amount is: boron mud accounts for 75% or 70% or 65% or 60%, and the magnesium slag accounts for 20% or 25% or 30%, and binding agent accounts for 5% or 8% or 10%.Described binding agent can be wilkinite, diatomite, limestone powder, magnesia, fireclay, both can be wherein any, also can be wherein several combination arbitrarily.
Production method: various raw material pulverizing are mixed, add water,, fire with rotary kiln then and form with balling-up mechanism ball.
The described concrete grammar of firing with rotary kiln is: starting material are after mixing balling-up, the rotary kiln baking of making a gift to someone, the limit adds the waterside and carries out bottom blowing in the roasting process, and adjusts flame, and ball is burnt to normalizing, reach 800-1200 ℃, cross about 25 minutes sintering and finish, the first one-step forming of haydite this moment can be seen the Solid solution of haydite light from kilneye, enter the expanded stage this moment, when Solid solution when going out 2 meters of kilneye, combustion-supporting sprays coal dust, coal dust acutely burns, temperature can reach 1250-1700 ℃, and generation high temperature, hyperbaric environment, Solid solution begins expanded, kiln discharge after 5-6 minute, obtain lightweight after the cooling, porous is spherical to gather materials, i.e. boric sludge fire resistant ceramsites.
