Abstract
The present invention relates to additive agents for metallurgy, which relates to additive agents for producing pellet mines and sintering mines. The present invention uses iron citrate as main formulation, and viscosity increaser, oxydant, reinforcing agents and preservative are respectively mixed into the main formulation so as to obtain additive agents for the production of sintering and pelletizing. The present invention has the advantages that the energy consumption is reduced, the grade of pellet mines is improved, and the production quality of sintering mines is improved.
Description
The present invention relates to the additive that metallurgical agglomerate and pellet are used.
The pellet of prior art, agglomerate manufacturer all are with the additive of wilkinite as pelletizing, sintering process.Because bentonitic addition is big, second-rate, caused the iron grade low in pellet formation, energy consumption increases, and productive expense is big; In agglomerate is produced, cause 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 metallurgical addition agent, 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 ironic citrate as basic raw material.Agglomerate is with adding tackifier, oxygenant, sanitas again, and its proportioning is: ironic citrate accounts for 55～70% weight, and tackifier account for 10～20% weight, and oxygenant accounts for 10%～20% weight, and sanitas accounts for 0.5～5% weight; Pellet is with adding tackifier again, toughener, and its proportioning is: ironic citrate accounts for 40～60% weight, and tackifier account for 30～50% weight, toughener 5～10% weight.
Embodiment and effect:
Embodiment 1
Used in sintering production, filling a prescription is: ironic citrate accounts for 62% weight, and tackifier account for 20% weight, and oxygenant accounts for 15% weight, and sanitas accounts for 3% weight, and wherein tackifier are Alpha-starch, and oxygenant is a nitrate, and sanitas is a Paraformaldehyde 96.Addition is at 3 o'clock very much in SINTERING PRODUCTION, and agglomerate output can improve more than 5% weight.
Embodiment 2
Used in sintering production, prescription is: ironic citrate accounts for 70% weight, and (factory is all chemical plant, southern part of the country company limiteds of Guangzhou flower to urea-formaldehyde resin (tackifier), the trade mark: Nan Xiu) 18% weight, Potcrate (oxygenant) accounts for 10% weight, phenol (sanitas) 2% weight.Can reach the effect of embodiment 1 equally.
In the prescription of used in sintering production, (factory is all chemical plant, southern part of the country company limiteds of Guangzhou flower to the also available Na-CMC of tackifier (Xylo-Mucine), the trade mark: Nan Xiu) or Precondensed UreaFormaldehyde Resin 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), the also available potassium permanganate of oxygenant, also available borax of sanitas or boric acid.
Embodiment 3
Pellet production usefulness, prescription: ironic citrate accounts for 50% weight, and tackifier account for 40% weight, and toughener is 10% weight, and wherein tackifier are Na-CMC, and toughener is a yellow soda ash, adds 1.5 ‰ green-balls and fall greater than 6 times/0.5m in pellet formation.Ultimate compression strength is greater than 1.0 kilograms of/balls, and the dry bulb resistance to compression is greater than 6 kilograms of/balls, and the finished ball resistance to compression is greater than 200 kilograms of/balls, and reducing property is good, and the low temperature Pulverization ratio is low.
Embodiment 4
Pellet production usefulness, prescription: ironic citrate accounts for 60% weight, and Alpha-starch (tackifier) accounts for 30% weight, and sodium hydroxide (toughener) accounts for 10% weight.Effect is fine equally.
In the pellet formation prescription, tackifier are for also can be polyacrylamide or guar gum etc., and toughener also can be tripoly phosphate sodium STPP or sodium polyphosphate.
