Abstract
The invention discloses a high-strength refractory castable taking a secondary guimo brick as an aggregate, which belongs to the technical field of refractory castable for cement kilns. The refractory castable comprises the following raw materials in percentage by mass: 50-60% of a secondary guimo brick with a particle size of less than or equal to 8mm, 10-20% of a scrap porcelain block material with a particle size of less than or equal to 8mm, 2-6% of silicon micropowder, 3-7% of aluminate cement, 5-10% of high aluminum powder and 3-8% of 180-mesh quartz powder, as well as 0.02-0.23wt % of an admixture. The refractory castable disclosed by the invention has the advantages that the regeneration and utilization of refractory materials are realized, so that resources are recycled and the usability of products is improved.
Description
Technical field
The invention belongs to refractory castable for cement kiln technical field, specifically provide the high-strength refractory mould material that a kind of secondary siliceous mullite brick is aggregate.
Background technology
Refractory materials is the important subsidiary material of ferrous metallurgy, cement, electric power, petrochemical industry, has a wide range of applications in every profession and trade.China consumes refractory materials about 1,000 ten thousand t in current year, waste and old refractory materials reaches 4,000,000 t, if waste and old refractory materials recycle can be made, also significantly can reduce the preparation cost of refractory materials, and drive the decline of the cost of industry Industrial products will bring significant economic and social profit with development.
The regeneration of domestic waste refractory materials is also in the stage at the early-stage, and the exploitation of developed countries to waste refractory materials are more Zao than China.The regeneration rate of China's refractory materials is also not high, only reaches 20%, and the waste and old refractory materials recovery utilization rate of metallurgy industry is about 40%.At present, the waste and old resistance to material of most enterprise adopts substantially buries process, relevant experimental study display: adopt a high proportion of waste and old refractory materials can make the very value product such as the refractory brick of high-quality, mould material, ramming mass, repair material, slag splashing furnace protecting material, tap hole filler, stuffing sand and slag former, and product performance can close to or reach the level of original product, some can also exceed the level of original product.Therefore, constantly appreciate in fireproof raw material market, today that fire-resistant finished product market value constantly reduces by user's cost needs, give full play to the surrogate of waste and old resistance to material as fire-resistant finished product, by technique means, promote its utility value further, have great importance.
Summary of the invention
The object of the present invention is to provide a kind of secondary siliceous mullite brick to be the high-strength refractory mould material of aggregate, solve product cost high, the problem of strength property difference.Make the again utilization of waste refractory materials in mould material.
A kind of secondary siliceous mullite brick is the high-strength refractory mould material of aggregate, be formulated as with mass percent: the secondary siliceous mullite brick 50 ~ 60% of granularity≤8mm, the useless porcelain block material 10 ~ 20% of granularity≤8mm, silicon powder 2 ~ 6%, aluminate cement 3 ~ 7%, high-alumina fly 5 ~ 10%, 180 object silica powders 3 ~ 8%; The admixture of another interpolation said ratio 0.02 ~ 0.23wt%.
Al in secondary siliceous mullite brick

2content 30-45wt%.
Admixture is one or more in tripoly phosphate sodium STPP, Sodium hexametaphosphate 99, sodium lignosulfonate and lithium hydroxide.
The invention has the advantages that: the regeneration realizing waste refractory materials, make resource obtain recycle, improve the use properties of product simultaneously.First apply secondary siliceous mullite brick as aggregate, make used refractory obtain regeneration in mould material, the high-strength refractory mould material simultaneously prepared can apply to the industries such as electric power, environmental protection, smelting and heating, improves the operation factor of equipment, enhances productivity; Secondly this product application secondary siliceous mullite brick effectively reduces costs, and product performance are also improved, and production technique is simple, use properties is good, reduces environmental pollution, resources circulation is recycled.
Embodiment
The proportioning raw materials of high-strength refractory mould material of the present invention presses following weight percents preparation:
Admixture content is the 0.02wt% of said ratio.
Production method is: first by aluminate cement, admixture premix in mixer, premix is evenly for subsequent use, again secondary siliceous mullite brick, useless electroceramics block material, silica powder, silicon ash, high-alumina fly are jointly mixed with the cement mixed, admixture Preblend in mixer, the mould material bag distribution packaging will mixed after mixing.
By the properties of the high-strength refractory mould material of examples produce of the present invention as following table
