Description

Preparing method Deng the siliceous bottom brick of molten tin bath of static pressure aluminium calcium
Technical field
The present invention relates to a kind of bottom brick of molten tin bath and method for making thereof, belong to technical field of refractory materials.
Technical background
Molten tin bath is the key equipment of float flat glass production line, and the glass metal after the fusing flows in the molten tin bath, swims on the tin liquor, and progressive forms level and smooth plate glass simultaneously, stores the used refractory brick of tin liquor and is called bottom brick of molten tin bath.The majority that uses in the market is the sal clay brick, in its use, because contained Na2O infiltrates in the brick through tin liquor lentamente in the glass, forms nepheline and also produces volumetric expansion and thermal stresses.When the metamorphic layer that contains nepheline was increased to certain thickness, metamorphic layer can peel off in the form of sheets, because its proportion is lower than tin liquor, when the fragment that peels off floats on the tin liquor face, can cause glass surface to scratch and glass defect.
The researchist of magnesium company (RHI) difficult to understand has adopted the basic material calcium aluminate to make bottom brick of molten tin bath, and US5420087 is said like patent, and the said firm is a raw material with calcium aluminate coarse particles and fine particle, and the employing calcium aluminate is a sticker, through vibratory compaction, dries after the maintenance, burns till.It is characterized in that adopting porous calcium aluminate coarse particles and fine particle is raw material; Aquation keying action with calcium aluminate forms the brick body; Making 1100 ℃ of burning posterior spiracle rates is 43%, alkali resistance oxide erosion, the calcium aluminate bottom brick of molten tin bath that coefficient of thermal expansion is low, thermal conductivity is low, gas permeation rate is low.Point out in the patent: for prevent brick in use with alkalimetal oxide reaction and reducing atmosphere under other reactions, SiO in the raw material 2, Fe 2O 3Mass percentage content should be lower than 1.5% respectively, SiO 2, Fe 2O 3Content preferably only be a small amount of.The shortcoming of this brick be coarse particles with fine particle between combine by hydrate, after 1100 ℃ of thermal treatments, calcium aluminate still comprises a small amount of combination water in combining mutually; In temperature use more than 1100 ℃; Combination water also will be overflowed, and the void content of goods also can increase, and can cause application risk.
Summary of the invention
The object of the present invention is to provide a kind of siliceous bottom brick of molten tin bath of aluminium calcium of high temperature sintering, alkaline-resisting MOX aggressiveness is good, coefficient of thermal expansion is low, thermal conductivity is low, the hydrogen diffusivity is low.
The present invention provides it rationally to be prone to the preparation method of row simultaneously.
The siliceous bottom brick of molten tin bath of aluminium calcium of the present invention, its chemical constitution mass percent is Al 2O 367-76%, CaO 21-28%, SiO 2Be 1.5-5%, surplus is common dirt, like MgO, Na 2O etc.
The XRD mineral facies of product consist of two calcium aluminates account for 70-90%, calcium hexaluminate and account for≤10% and gehlenite account for 8-25%.
The void content of product is 18-24%.
The preparation method who rationally is prone to row is following:
After batching, moulding, high temperature burn till, process, it is characterized in that ingredients by weight per-cent is: particle diameter be particle 20-35% in the calcium aluminate coarse particles 30-45% of 3-1mm, the calcium aluminate that particle diameter is 1-0.1mm,＜0.088mm combines fine powder 25-40%.
Wherein, the void content of calcium aluminate raw material is less than 3%, and its chemical constitution mass percent is: Al 2O 373-79%, CaO 21-27%, Fe 2O 3≤0.10%.
In conjunction with fine powder is the mixture of calcium aluminate fine powder, alpha-alumina fine powder and silica compound fine powder, presses SiO 2The 1.5-5% that accounts for compound chemical constitution mass percent adds the silica compound fine powder, presses SiO in the mixture 2The 0.8-1.4 of mass percent extraordinarily goes into alpha-aluminium oxide powder, and all the other are the calcium aluminate fine powder.
In conjunction with silica compound in the fine powder be select for use at least in clay, quartz, diopside, the wollastonite a kind of.
After batch mixes, adopt the moulding of isostatic pressing mode to get base substrate, forming pressure is 50-200Mpa.
Burn till behind the body drying, general nature was gone into klining in dry 1-3 days.
Firing temperature is 1300-1450 ℃, and burning till soaking time is 10-40 hour.
The firing temperature system is following:
10 ℃-200 ℃ heat-up rate 1-2 ℃/minute
200 ℃-1300 ℃ heat-up rate 1-3 ℃/minute
1300-1450 ℃ of insulation, soaking time are 10-40 hour
Cease fire and lower the temperature naturally cooling.
Compared with prior art, the present invention has following beneficial effect:
It is coarse particles and fine particle that the present invention adopts fine and close calcium aluminate, and adding alpha-aluminium oxide powder is wedding agent with the silica compound powder, through isostatic pressing, burn till after formation be the product of essential mineral phase with two calcium aluminates, gehlenite, calcium hexaluminate.Do not contain hydrate in the product; Internal structure is even; Anti-tin liquor good penetrability, alkaline-resisting MOX corrode, coefficient of thermal expansion is low, thermal conductivity is low, the hydrogen diffusivity is low, have solved clay matter bottom brick of molten tin bath and have been subject to alkalimetal oxide erosion generation nepheline, cause the problem of brick volumetric expansion, peeling; Can improve the work-ing life of bottom brick of molten tin bath, and can reduce by the glass defect of bottom brick of molten tin bath generation and the calorific loss of molten tin bath bottom.
