Description
Technical field
The invention belongs to metallurgical technical field of refractory materials, specifically is a kind of feed way of production resin-bonded carbon containing refractory.
Background technology
Wedding agent occupies important status in carbon containing refractory.It is to the mixing of pug, processability, and the microstructure of goods all can produce very large influence.With regard to the moulding of mixing, people hope that wedding agent has good wettability to refractory aggregate and carbon material.Wedding agent is divided into organic bond and inorganic bonding agent two big classes.Be organic bond wherein to the best wedding agent of carbon materials wettability---liquid phenolic resin.The mode that present resin-bonded carbon containing refractory mixes is earlier all fine powder materials (comprising carbon material) to be put into the premixed device pre-mixing, processes powder mix; Elder generation joins particulate material in the muller when mixing, and does and mixes several minutes, when muller rotates, disperses to add resin, behind the mixed several minutes, adds powder mix again, mixes.Can produce resin balls when mixing so usually, its staple is carbon materials and fine powder, and carbon materials and fine powder are referred to as resin balls by the more resin-bonded spheroidal thing that forms.The composition of resin balls has determined that its erosion resistance is poor.The general diameter of resin balls sieves mixed pug with sieve about 1～7cm usually, and big resin balls can be sifted out, but the less resin balls of size has been stayed in the pug inevitably.Resin balls is sneaked in the pug, in brick, forms to be prone to corrosion area, forms fusion hole during the contact molten steel, has a strong impact on the quality of refractory product, is prone to take place serious accidents such as bleed-out.At " refractory materials " 2007; 41 (supplementary issues) have the document of a piece " characteristic of modified resin and the effect in alumina-carbon material "; The document has been told about with common resol and has been compared; Three kinds of modified resin show different hot analytical performances, and the temperature that exothermal peak is corresponding is interval different with exothermic temperature, and the modified resin oxidation-resistance is strong and weak different.Adopt the wedding agent of three kinds of modified resin as alumina-carbon material respectively, the result shows that modified resin improves alumina-carbon material normal temperature, medium temperature intensity; Modified resin has improved the oxidation-resistance and the hydration resistance of alumina-carbon material.But do not speak of the problem of relevant controlling resin balls in this document.
Summary of the invention
The present invention discloses a kind of feed way of resin-bonded carbon containing refractory; Solved the problem that produces resin balls when the resin-bonded carbon containing refractory mixes; Can reduce simultaneously the add-on of powder mix, promptly reduce the additional proportion of valuable raw material in all raw materials, reduce raw materials cost.
The order of addition(of ingredients) that normal conditions resin-bonded carbon containing refractory mixes is particulate material 60%～63% at different levels → when muller rotates, disperse to add liquid phenolic resin → adding powder mix 37%～40% (all powder premixs form) → discharging to sieve simultaneously.
Technical process of the present invention is: particulate material at different levels → mixing → when muller rotates disperse to add liquid phenolic resin → mixing → adding powder mix → mix → add carbon black → mixing → qualified pug discharging.
Raw material of the present invention consists of (weight percent) 65%～79%, powder mix 20%～34%, carbon black 1%～5%.
The refractory materials of production resin-bonded is not exclusively the same according to the purposes variable grain material and the powder mix raw material of product; The present invention is when production resin-bonded aluminum-zirconium-carbon slide; Its particulate material at different levels comprise: one or more in sintering plate corundum particle, alundum particle, fused white corundum particle, electric smelting compact alumina particle, the zirconium mullite particle, powder mix are one or more in plate diamond spar powder, alundum powder, fused white corundum powder, electric smelting compact alumina powder, activated alumina micro mist, silica flour, aluminium silica flour, boron carbide powder, graphite, the electrode powder.
The present invention is when production resin-bonded aluminum-carbon sliding; Particulate material at different levels comprise: one or more in sintering plate corundum particle, alundum particle, fused white corundum particle, the electric smelting compact alumina particle, powder mix are one or more in plate diamond spar powder, alundum powder, fused white corundum powder, electric smelting compact alumina powder, activated alumina micro mist, silica flour, aluminium powder, aluminium silica flour, boron carbide powder, graphite, the electrode powder.
The inventive method also can be selected the different particulate material and the prescription and the ratio of powder mix according to the purposes of other production, produces by its technical process, reaches the purpose of avoiding the generation of resin balls in production process.
Prior art particulate material add-on 60%～63%, powder mix add-on 37%～40%, wherein 5%～16% powder mix adds for reducing resin balls, and its cost is very high; Because the present invention adopts present feed way; Avoided the generation of resin balls, therefore the particulate material add-on rises to 65%～79% now, and the powder mix add-on reduces to 20%～34%; Promptly reduce the additional proportion of valuable raw material in all raw materials, reduced raw materials cost.
The invention solves the resin-bonded carbon containing refractory and mix and produce the problem of resin balls, thereby reduced after the pug discharging operation of filtering resin balls with sieve, make mix more even; The pug composition is more near prescription; Alleviate working strength of workers simultaneously, improved labour productivity, eliminated the unsafe factor that brings to refractory materials because of resin balls; Improved the quality product of refractory materials; Can reduce simultaneously the add-on of powder mix, promptly reduce the additional proportion of valuable raw material in all raw materials, reduce raw materials cost.The cold crushing strength of the slide plate of producing with this method is also brought up to 160～200MPa by 120 original～150MPa.
