Abstract
The invention relates to a forsterite zirconia brick and a producing method thereof. Magnesium sand, forsterite sand, zircon sand, sulphite liquor and calcium lignosulphonate are mixed according to the weight part. The producing method of the forsterite zirconia brick is as follows: granule materials of the magnesium sand and the forsterite sand are added to a sand mixer to be mixed without water for 3 to 5 minutes; the sulphite liquior and the calcium lignosulphonate are added to be mixed with water for 3 to 7 minutes, and then the fine powder of the magnesium sand, the forsterite sand and the zircon sand is added to be mixed for 8 to 12 minutes; the mixed material is added to a mould to be pressed into a brick body; the shaped brick body is dried in a drying kiln at 70-110 DEG C no less than 12 hours until the water content in the dried brick body is not higher than 8 percent; the dried brick body is sent into a tunnel kiln to be fired at 1580-1680 DEG for 3 to 5 hours. The forsterite zirconia brick has no toxin or harm and is the fireproof alkali brick suitable for the middle part and the upper part of the glass kiln.
Description
Technical field
The invention belongs to fire resisting material field, relate to the basic refractory forsterite zirconia brick and the method for manufacture thereof that are applicable to that the glass regenerative chamber checker is used particularly.
Background technology
The glass kiln is when operation, and top exists a large amount of high-temperature alkaline gases, i.e. saltcake; The middle part is because temperature produces acid rain than low being prone to, and the middle and upper part is because variation of temperature if temperature is low, also can produce acid rain.Therefore, according to the operation characteristic of glass kiln, when building glass kiln body, adopt the different bricks of joining usually: the middle part is a magnesia chrome brick, upward the middle part is a magnesia brick, and top is magnesia brick or magnesium zirconia block.Magnesia chrome brick in use forms Cr easily
6+, environment is produced toxic action, be on record; In addition; When building glass kiln checker, owing to need the different bricks of joining, design is produced and is made troubles to kiln; More serious is; If the different insufficient heights of joining the brick design, high-temperature alkaline gas or acid rain will produce serious erosion to the glass kiln checker of periphery in operational process so, make the checker distortion.
Summary of the invention
In order to address the above problem, the present invention provide a kind of toxicological harmless, be applicable in the glass kiln, the refractory brick on top, make the glass kiln at the middle part, all to adopt with a kind of brick be forsterite zirconia brick for top and middle and upper part.
Another object of the present invention provides a kind of method of manufacture of forsterite zirconia brick.
To achieve these goals, the technical scheme of the present invention's employing is:
A kind of forsterite zirconia brick, process by weight ratio by following raw material:
1mm～20～25 parts in 3mm magnesia,
0.088mm 10～15 parts in～1mm magnesia,
10～13 parts in≤0.088mm magnesia,
1mm～20～25 parts of 3mm forsterite sands,
0.088mm 10～15 parts of～1mm forsterite sands,
10～13 parts of≤0.088mm forsterite sands,
4～10 parts of≤0.088mm zircon sands,
3～5 parts of spent pulping liquors,
1～2 part of calcium lignin sulphonate.
The method of manufacture of above-mentioned forsterite zirconia brick comprises the steps:
1) raw material pulverizing screening: magnesia and forsterite sand is broken in crusher or ball mill; Respectively after 3mm screen cloth, 1mm screen cloth and the screening of 0.088mm screen cloth; Processing magnesia and forsterite sand, the granularity that granularity is 1mm～3mm is magnesia and the forsterite sand of 0.088mm～1mm, granularity is≤and magnesia powder and the forsterite sand fine powder of 0.088mm; Zircon sand is processed granularity≤0.088mm;
2) batch mixing: by weight ratio; Taking by weighing granularity is that 1mm～3mm and granularity are the particulate material of magnesia and the forsterite sand of 0.088mm～1mm; Add to do in the sand mill and mixed 3～5 minutes, add spent pulping liquor and calcium lignin sulphonate then, wet mixing 3～7 minutes; The magnesia powder, forsterite sand fine powder and the zircon sand fine powder that add granularity≤0.088mm again, mixed 8～12 minutes;
3) moulding: the material that mixes is added in the mould, add and be pressed into base substrate;
4) drying: is dry in 70～110 ℃ the dry kiln with molding blank in temperature, is not less than 12 hours time of drying, moisture content≤0.8% in the base substrate of dry back;
5) burn till: the base substrate that drying is good is delivered in the tunnel, and firing temperature is 1580 ℃～1680 ℃, and firing time is 3～5 hours.
Among the present invention, select the magnesia of content of magnesia >=95% and the zircon sand of zirconia content >=65% usually for use.
The invention has the beneficial effects as follows: because starting material such as magnesia of being selected for use and forsterite do not contain chromium, so eliminated pollution of chromium.Forsterite is natural mineral products, and zircon sand is a natural matter, therefore, need not consume too much fuel, has reduced cost, has reduced topsoil.Forsterite zirconia brick of the present invention, owing to adopted natural boltonite and zircon sand as raw material, so, the high-temperature alkaline gas on glass kiln top and the acid rain at middle part are all had the anti-erosion function.Thereby when design glass kiln; Can be no longer basic brick classification usefulness, until a kind of brick of material all can be adopted in top, making whole regenerator middle and upper part all is forsterite zirconia brick of the present invention from the middle part; Make design and construction convenient; And in use, can not cause glass kiln checker is corroded, and produce distortion.
