Description
The present invention relates to the fire-retardant nodulizer that uses in metallurgical and the iron casting production, belong to the chemical metallurgy technical field.
The CN1065886 patent on November 4th, 92 disclosed " spheroidal graphite cast iron instantaneous dense flow spheroidizing container ", and this patented technology is burnt when implementation process middle-weight rare earths magnesium alloy and molten iron stream converge sometimes, does not reach processing requirement.Widely used rare earth ferrosilicomagnesium nodulizing agent exists the serious environmental pollution to reach operator's Health hazard in preparation process and spheroidizing simultaneously, and the serious waste of the starting material and the energy.These problems are metallurgical and the cast iron industry is sought the difficult problem that solves in recent decades always.
The objective of the invention is to remedy the deficiency of prior art, the environmental pollution that provides a kind of and have flame retardant resistance, can solve in the magnesium-rare earth production process guarantees double layer granular fire-retardant nodulizer composition of safety in production and preparation method thereof.
Composition of the present invention comprises following component: all be weight percentage.
Matrix: pure magnesium or magnesium chloride 2-10%, chlorination mishmetal or norium 2-20%, trace alloying element (comprising bismuth, manganic compound) 0.04-0.8%, surplus is a ferrosilicon.
Matrix is rare earth magnesium ferrosilicon alloy (RE also
7Mg
9).
Flame-retardant layer: the halogenide of alkaline-earth metal or compound, graphite, ferrosilicon powder, one of or the arbitrarily mixing of component arbitrary proportion.Flame-retardant layer thickness 0.5-2mm.
Binding agent: resol or middle nitrogen resin.
Preparation method of the present invention comprises the steps: that a. is with pure magnesium or magnesium chloride, chlorination norium or norium, ferrosilicon, trace alloying element (comprising bismuth, manganic compound) mechanically mixing is in proportion made particle-matrix with 2-5% resene binding agent on tablets press; B. wrapping up one deck flame-retardant layer on its outer surface behind the external application 2-5% resin again on the above-mentioned particle-matrix.Flame-retardant layer is the halogenide or the compound of alkaline-earth metal, graphite, ferrosilicon powder, one of or the arbitrarily mixing of component arbitrary proportion.Flame-retardant layer thickness 0.5-2mm.
Composition of the present invention is a double layer granular.Core is the nodularization element of inflammable easy reaction, and skin is fire-retardant protection component.
Flame-retardant layer has fire retardation to matrix, simultaneously processed molten iron is played purification, desulfurization and promotion nodularization and promotion transformation mutually.Thereby the high save energy of utilization rate of raw materials reduces production costs.According to the purification in iron liquid of the halogenide of different alkaline-earth metal or compound, desulfurization and promotion nodularization with promote the difference between the effects that changes mutually of iron, select its component and proportioning, its foundation is the best nodularization effect and the optimum economic benefit of base iron quality and magnesium iron type.Double layer granular fire-retardant nodulizer composition of the present invention could burn more than later half second at the chance molten iron; The nodulizing grade of handled magnesium iron is all above 2 grades; The nodulizing agent cost that more is apparent that spheroidizing descends more than 40%; The problem that has thoroughly solved simultaneously environmental pollution and saved the starting material and the energy.
