Description
Technical field
The present invention relates to compound binding agent and its production and use, belong to field of metallurgy.
Background technology
The breeze of metallic ore after pulverizing grinder choosing can not directly carry out Metallurgical processing, so by breeze ball processed for the production of becoming current main production situation, that the cooled agglomerated pellet preparing has is of high grade, intensity good, even-grained feature, is the good furnace charge of the equipment such as blast furnace, rotary hearth furnace, rotary kiln, shaft furnace, car bottom furnace.
Binding agent is the key component that breeze is made cooled agglomerated pellet, it is the important component that improves pelletizing resistance to compression, dropping strength, anti-spalling, require binding agent to there is good adhesive property, wetting ability, dispersiveness and larger specific surface area, energy high dispersing after chance water, and the product position influence to pellet is the smaller the better, up to now, the binding agent for industrial pelletizing has wilkinite, clay, water glass, cement, slaked lime, Xylo-Mucine, pendant benefit, molasses, humic acids, xylonic acid, starch etc. and some complex adhesives.Although of a great variety, consider the general-purpose adhesive of finding to be difficult to applicable multi mineral powder after technology, economic dispatch factor, generally, be all according to specific raw material, select corresponding applicable binding agent.The index that the selection of compound binding agent need to consider has: (1) normal temperature viscosity; (2) significantly do not reduce pelletizing metal content; (3) quality of its mechanical performance index of pelletizing of producing; (4) detrimental impurity content is how many; (5) harmless while using.
The most disk pellet forming process that adopt of current domestic pellet formation enterprise, the binding agent of employing is mainly wilkinite, and addition is 1.5%～4.0%, but bentonitic main component is (Al
2, Mg
3) Si
4o
10(OH)
2nH
2o, is a kind of containing Al, Mg, binding agent that Si is higher, and these compositions have reduced the grade of pellet, unfavorable to subsequent smelting.For pelletizing grade is not reduced, emtallurgy research worker has adopted again the organic binder bonds such as xylonic acid, Xylo-Mucine, pendant benefit, this class binding agent has good cohesiveness, when high temperature, can burn, little to pelletizing product position influence, but because price is high, the high temperature capability of antidetonance of pelletizing and metallurgical performance can not meet the processing requirements such as blast furnace, rotary hearth furnace, rotary kiln completely, thereby fail to apply industrial.For addressing the above problem, developed again in recent years multiple organic/inorganic composite binding agent, but all because in use there being some problems such as anti-knocking property are poor, intensity is low, failed in industrial popularization.
Application number is that 92104094.6 Chinese patent discloses a kind of high strong polyviny alcohol binder and preparation method thereof, and specifically disclose borax and PVA linked reaction occurs, make PVA sex change, generate high strong polyviny alcohol binder, wherein, PVA content is 12-14%, borax is 2-3% (5% aqueous solution), and water is 84-85%, but due to its binding agent obtaining mobility extreme difference at normal temperatures, for colloid, be not obviously suitable in the cold fixed moulding of breeze.
