Abstract
The present invention relates to an organic binder for metallurgy, which relates to a binder for pellet mines and sintering mines. The organic binder for pellet mines is prepared by that the organic binder namely sodium carboxymethyl cellulose (CMC) is used as main raw materials, and a viscosity increaser, a reinforcing agent and a preservative are mixed into the raw materials to form the organic binder for pellet mines. Or an oxydant, a promoter and a viscosity increaser are added to form the organic binder for sintering mines through etherification reaction. The present invention has the advantages that the grade of iron is improved, the energy consumption is reduced, and the yield is increased.
Description
The present invention relates to the binding agent that metallurgical agglomerate and pellet are used.
The pellet of prior art, agglomerate manufacturer all are with the binding agent of wilkinite as pelletizing, sintering process.Because bentonitic addition is big, second-rate, caused the iron grade low in pellet formation, energy consumption increases, productive expense increases; In agglomerate is produced, caused bed permeability poor equally, problem such as energy consumption increases, and expense is big.
The purpose of this invention is to provide a kind of organic binder bond, consumption is few, make bed permeability good, cut down the consumption of energy, reduce production cost.
Technical scheme of the present invention is such: adopt general organic binder bond Xylo-Mucine (Na-CMC) as basic raw material, the remix tackifier, toughener and sanitas, its proportioning is: Na-CMC accounts for 60-80% weight, tackifier account for 10-20% weight, toughener accounts for 9-20% weight, and sanitas accounts for 0.5-5% weight, as the binding agent of pellet production; Or carboxymethyl cellulose sodium (Na-CMC), add oxygenant again, promotor helps tackifier and carries out etherification reaction, its proportioning accounts for 45-70% weight for (Na-CMC), oxygenant accounts for 15-35% weight, promotor accounts for 10-30% weight, and tackifier account for 1-5% weight, as the binding agent of agglomerate production.
Embodiment and effect.
Embodiment one,
Pellet usefulness, filling a prescription is: Xylo-Mucine (Na-CMC) accounts for 72% weight, and (factory is all chemical plant, southern part of the country company limiteds of Guangzhou flower, and the trade mark: Nan Xiu), tackifier account for 15% weight, and toughener accounts for 10% weight, and sanitas accounts for 3% weight.Tackifier Alpha-starch wherein, toughener yellow soda ash, sanitas Paraformaldehyde 96.Consumption 1.0-1.5 ‰ weight in the system pellet, than obviously improving the iron grade with wilkinite, reduce coke ratio, increase iron output, improve production performance, green-ball falls greater than 6 times/0.5 meter, compression strength of green pellet is greater than the 1Kg/ ball, and dry bulb pushes greater than 6 kilograms/ball, and the finished ball resistance to compression is greater than 200 kilograms/ball, and reducing property is good, and the low temperature Pulverization ratio is low.
Embodiment two,
(factory is all chemical plant, southern part of the country company limiteds of Guangzhou flower to tackifier with urea-formaldehyde resin, the trade mark: Nan Xiu) or polyacrylamide (factory is all chemical plant, southern part of the country company limiteds of Guangzhou flower, the trade mark: Nan Xiu) or guar gum (place of production is an India, brand: avenge imperial S-20), toughener is with tripoly phosphate sodium STPP or sodium polyphosphate, and sanitas is with borax or boric acid.Other parameters and effect and with embodiment one.
Embodiment three,
Agglomerate usefulness, filling a prescription is: Xylo-Mucine (Na-CMC) accounts for 52% weight, and oxygenant accounts for 25% weight, etherificate promotor accounts for 20% weight, and tackifier account for 3% weight, wherein the oxygenant potassium perchlorate, promotor is used zinc oxide, the tackifier polyacrylamide.Use only 0.3 ‰ weight in agglomerate, energy enhancing mixed material improves bed permeability, cuts down the consumption of energy, and the iron rate ratio improves 10% weight with wilkinite.
Embodiment four,
Oxygenant is with Potcrate or potassium permanganate; Promotor is with boric acid or borax or other borides; Tackifier are with urea-formaldehyde resin or guar gum.Other parameters and effect are with embodiment three.
