Problems solved by technology

However, the currently used slag-accumulating agents are mainly imported volcanic ash, and there are no reports of slag-accumulating agent products with independent intellectual property rights, which leads to high use costs and severely limits the development of the domestic tin bronze industry.

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 [0001] The invention belongs to the technical field of chemical industry and metallurgy, and relates to a bronze slag gathering agent and a preparation method thereof, in particular to a tin bronze slag gathering agent and a preparation method thereof. Background technique [0002] Tin bronze is an alloy with tin as the main alloying element, and has the smallest shrinkage rate among non-ferrous metal alloys. Because tin bronze has good wear resistance and corrosion resistance, the castings prepared from it are widely used in elastic elements of steam boilers, ships and other machinery and equipment, as well as parts subject to friction in automobiles and other industries. [0003] During the smelting process of tin bronze, since the melting point of some metal oxidation products (such as SnO) is lower than the melting temperature of the alloy, these oxides float on the copper water in liquid form and are not easy to separate from the copper water. If the sl...
