Abstract
The invention discloses a method for manufacturing a fused cast zirconia-alumina ramming mass from casting waste materials, which comprises the following steps: reclaiming the waste materials when casting a fused cast zirconia-alumina, picking up material blocks adhered with heat-insulating materials, and taking the other material blocks for later use; crushing the picked high-quality material blocks into grains of which the granularity is less than 5mm, performing magnetic separation on the grains to remove irons, and taking the separated grains for later use; and uniformly blending 65 parts of the prepared grains, 20 parts of high-alumina cement, 10 parts of zirconia aluminium oxide powder and 5 parts of white mud in a material blender, and thus obtaining a finished product of the fused cast zirconia-alumina ramming mass. The ramming mass is mainly applied to caulked joint parts of fused cast zirconia-alumina refractory bricks. The method has the advantage of capability of saving production cost, reducing consumption and changing waste materials, namely the primary casting waste materials, into things of value; and the produced ramming mass has a strong cohesiveness, particularly is increased by 20 percent in the aspect of high-temperature resistance when compared with the primarily used ramming mass, is better applied to glass furnaces and other high-temperature furnaces, and is approved by a plurality of countries.
Description
Technical field
The present invention relates to ramming mass, especially relate to a kind of method of utilizing casting waste materials to produce electro-fused zirconia-corundum ramming material.
Background technology
Ramming mass is to be starting material with silicon carbide, graphite, electric calcined anthracite, the multiple ultrafine powder additive of admixture, electric smelting cement or compound resin are the diffusing shape material body that wedding agent is made, and are used to fill shaft cooling apparatus and masonry gap or masonry screed-coat stopping composition.The ramming mass chemical stability is good, and anti-washing away resistance to worn, antistripping, and heat-resisting shake is widely used in metallurgy, building materials, non-ferrous metal metallurgy, chemical industry, manufacturings such as machinery.
When refractory materials manufacturer produces in the electric fused zirconium corundum cast, the cast liquation can generating unit divide loss, the material piece that the solution cooling back of these losses forms is generally given it up by producer as waste material, year in and year out, the waste material of these accumulations has polluted environment on the one hand, has also caused waste on the other hand.
Summary of the invention
The object of the present invention is to provide a kind of method that saves production cost, utilizes casting waste materials to produce electro-fused zirconia-corundum ramming material.
For achieving the above object, the present invention can take following technical proposals:
The method of utilizing casting waste materials to produce electro-fused zirconia-corundum ramming material of the present invention, it comprises the steps:
The first step: select, the scrap that runs off when electric fused zirconium corundum is poured into a mould reclaims, and is stained with choosing of lagging material on the material piece, and its clout piece is standby;
Second step: broken, deironing, with the above-mentioned high-quality material piece of picking out be crushed to granularity less than the particulate material of 5mm after standby behind the iron removal by magnetic separation;
The 3rd step: get 65 parts of second particulate material that make of step, 20 parts of high-alumina cements, 10 parts in zircon corundum powder, 5 parts of white claies are gone into above-mentioned raw materials after mixer mixes, and can obtain the electro-fused zirconia-corundum ramming material finished product.
The physical and chemical index of prepared ramming mass finished product is: SiO
216～17%, ZrO
230～32%, Al
2O
347～49%, volume density is 3g/cm
3, this ramming mass mainly is used in zirconia-corundum refractory brick filleting position.
The invention has the advantages that and to save production cost greatly, reduce and consume, the casting waste materials of giving it up is originally turned waste into wealth, and the ramming mass cohesiveness that goes out as its main material production is strong, has particularly improved the 20% (ZrO of traditional ramming mass than original used ramming mass aspect high temperature resistant
2Content is 28%, the ramming mass ZrO that this method is made
2Content is 30～32%), be applicable to high temperature kiln uses such as glass furnace more, be subjected to the approval of a plurality of countries.
Embodiment
The method of utilizing casting waste materials to produce electro-fused zirconia-corundum ramming material of the present invention, it comprises the steps:
The first step: select, the scrap that runs off when electric fused zirconium corundum is poured into a mould reclaims, and is stained with choosing of lagging material on the material piece, and its clout piece is standby;
Second step: broken, deironing, the above-mentioned high-quality material piece of picking out is broken into the following macrobead of granularity 15mm with jaw crusher earlier, after being processed into small-particle material below the granularity 5mm, pair roller sends into magnetic separator again, remove behind the ferro element in the small-particle material standby;
The 3rd step: take by weighing 65 parts of second particulate material that make of step, 20 parts of the high-alumina cements of label 700#, 10 parts in 280 purpose zircon corundum powder, 5 parts of white claies after above-mentioned raw materials put into mixer and mix 10～15 minutes, can obtain SiO
216～17%, ZrO
230～32%, Al
2O
347～49%, volume density is 3g/cm
3The electro-fused zirconia-corundum ramming material finished product.
The ramming mass that the present invention produces is mainly used in the sealing ply at the bottom of the glass furnace pond, compares with the ramming mass that routine is used to have the following advantages: 1, good stability; 2, its physical and chemical index is better than tradition used ramming mass, particularly ZrO
2Content has improved 2～3% than originally; 3, production cost reduces by 30～40%; 4, the program of manufacturing is more simplified.
