Abstract

The invention discloses a refractory brick prepared from Zhundong coal combustion waste residue, and a preparation method of the refractory brick. The refractory brick is prepared from the following raw materials in parts by weight: 50-60 parts of coal slag, 10-20 parts of fused magnesite, 10-20 parts of mullite, 5-10 parts of fly ash, 5-8 parts of cement, 5-8 parts of clay and 1-5 parts of sodium hexametaphosphate. The preparation method concretely comprises the steps of crushing the coal slag and screening the crushed coal slag; after that, weighing the coal slag and other raw materials according to the proportion, evenly mixing, adding water into the mixture and stirring; molding by pouring into a mould, and then demoulding; finally, sintering at the temperature of 1200-1500 DEG C to obtain the refractory brick. By recycling the coal slag, the not only can the waste residue be treated, but also waste is changed into valuable, thus improving the added value of products and realizing the economical and environmental-friendly effect.

Description

Refractory brick prepared using quasi- east coal combustion waste residue and preparation method thereof
Technical field
The invention belongs to quasi- east coal waste residue recycles field and in particular to a kind of utilize waste residue preparation after the coal combustion of quasi- east Refractory brick and preparation method thereof.
Background technology
Quasi- east coalfield is in the super-huge coalfield in Xinjiang, and prognostic reserves reach 3900 × 108T, cost of winning is cheap.Accurate The moisture of eastern coal, volatile matters are higher, and ash, sulphur content are very low, and calorific value is medium；In the coal of quasi- east, na content is high, in combustion process easily Slagging scorification, belongs to the serious coal of contamination degree.Cinder after burning and flyash growing amount are big, and stacking is main side to be processed Formula, but if processing only with the method piled up, can cause to environment largely to destroy.
Content of the invention
It is an object of the invention to provide a kind of refractory brick using the coal combustion waste residue preparation of quasi- east and preparation method thereof, it leads to Cross cinder to be recycled, waste residue can not only be processed moreover it is possible to turn waste into wealth, improve added value of product, economic and environment-friendly.
For solving above-mentioned technical problem, the technical solution adopted in the present invention is: one kind is using quasi- east coal combustion waste residue system Standby refractory brick, is made using following raw material by weight: cinder 50-60 part, fused magnesite 10-20 part, mullite 10- 20 parts, flyash 5-10 part, cement 5-8 part, clay 5-8 part and sodium hexameta phosphate 1-5 part.Wherein sodium hexameta phosphate and cement are made For bonding agent, sodium hexameta phosphate, as high temperature adhesives, can promote raw material preferably to fuse.
Preferably in scheme, made using following raw material by weight: 55 parts of cinder, 15 parts of fused magnesite, Mo Lai 15 parts of stone, 8 parts of flyash, 6 parts of cement, 6 parts of clay and 3 parts of sodium hexameta phosphate.
Described cinder and flyash are defined the waste residue producing after eastern coal combustion.
Described raw material also includes 10 parts of forsterite, and granularity is in 100-200 micron.
Described raw material also includes epoxy resin 1-5 part.
, in below 5mm, flyash is in below 1mm for described cinder.
The granularity of described forsterite and mullite is in below 3mm.
A kind of method preparing refractory brick using quasi- east coal combustion waste residue, comprises the following steps:
Cinder is carried out pulverizing, sieves, then weighs cinder and other raw material mix homogeneously by proportioning, add water stirring, in mill Moulding by casting in tool, the demoulding, finally it is sintered obtaining refractory brick at 1200-1500 DEG C.
The temperature of sintering is 1300-1400 DEG C.
Mass ratio both when adding water after described raw material mixing is 3-5:1.
The chemical composition of cinder and flyash is more similar, and main chemical compositions are sio2、al2o3、fe2o3, cao and a small amount of Magnesium, sulfur, carbon etc..But because cinder easily lumps, the cinder after burning could be used for after needing to be crushed or pulverized Prepare refractory brick, be easy to it and mix homogeneously with other materials.
The method have the advantages that
1) make use of substantial amounts of cinder and flyash in formula, be that waste residue utilization provides a kind of new thinking, especially cinder Utilization reached 50% about, can significantly mitigate the processing pressure of cinder moreover it is possible to turn waste into wealth.
2) due to adding fused magnesite in formula, it generates magnesium olive with the silicon dioxide sintering in cinder and flyash Olive stone, forsterite is coordinated with mullite, is the refractory material of high-quality, and melt temperature is high, and resistance to sudden heating and intensity are good；Viscous The use of the bonding agent such as soil, sodium hexameta phosphate and cement, can make refractory aggregate preferably combine, increase further its intensity, Shock resistance and stability.
3) this refractory brick can be used on kiln or other buildings high to fire resistance rating, its refractoriness 1600 DEG C with On, it is widely used.
