Abstract
The invention discloses a tin bronze slag conglomeration agent, which is characterized by comprising the following components in percentage by mass: 68.1-73.8% of SiO2, 1.5-12.0% of Al2O3, 0.2-3.6% of Fe2O3, 1.0-8.9% of CaO, 4.5-14.0% of Na2O, 0.3-3.8% of MgO, 0.1-2.9% of K2O and the balance of other inevitable impurities. During preparation, the components are weighed according to the formula and mixed uniformly; the mixture is put into a pulverizer and pulverized, wherein the pulverizing granularity is 20 to 100 meshes; and finally, the powder obtained by pulverizing is bagged and sealed to obtain the finished product. The tin bronze slag conglomeration agent fills the blank of domestic tin bronze industry in the field of slag conglomeration agents, has the characteristics of low cost, good slag conglomeration effect, short slagging-off time and low copper loss, does not destroy the environment when in use, is nontoxic and dust-free and does not have peculiar smell.
Description
Technical field
The invention belongs to field of chemical metallurgical technology, relate to poly-slag agent of a kind of bronze and preparation method thereof, particularly a kind of tinbronze gathers slag agent and preparation method thereof.
Background technology
Tinbronze take tin as a kind of alloy of main alloy element, has minimum shrinking percentage in non-ferrous metal alloy.Because tinbronze has good wear-resisting, corrosion resistance nature, prepare gained foundry goods by it and be widely used in the elasticity original paper of steam boiler, boats and ships and other machinery equipment and automobile and other industrial parts bearing friction.
In tinbronze fusion process, because partial metal oxide product (as SnO) fusing point is lower than alloy melting temp, makes these oxide compounds swim in copper in liquid form waterborne, be not easily separated with copper water.If directly carry out skimming, slag-removing time can be caused long, operation not easily, has a large amount of copper water and runs off along with slag, cause cost to be wasted in process of simultaneously skimming, the production development of serious restriction tinbronze.
For improving effect of skimming, enhancing productivity, needing before skimming to use poly-slag agent to be assembled by liquid slag caking, being beneficial to carry out effectively skimming fast, reducing copper loss in process of skimming simultaneously and lose.But use poly-slag agent mainly based on import volcanic ash at present, the poly-slag agent product simultaneously with independent intellectual property right does not also have report, and this causes use cost to remain high, and seriously limits the development of domestic tinbronze industry.Therefore, develop the efficient poly-slag agent with independent intellectual property right, break external monopolization, reduce production cost, the development of China's tinbronze industry is had important practical significance.
