Abstract

A heating agent for metal smelting comprises components including, by mass, 21-25 parts of aluminum powder, 2-8 parts of zinc silicate, 5-10 parts of quartz sand, 2-5 parts of kieselguhr, 11-13 partsof silicon carbide, 3-10 parts of an additive, 2-8 parts of water glass, 3-6 parts of pulverized coal, 11-15 parts of nitrate, 3-6 parts of a stabilizer and 8-13 parts of a binding agent. A preparingmethod of the heating agent for metal smelting comprises the following steps that firstly, solid substances in the components are added in a reaction kettle, and ball milling and uniform mixing are conducted; secondly, liquid components are added in the mixture, and uniform mixing is conducted; thirdly, and after natural cooling, the mixture is scattered into powder. The components used in the obtained heating agent do not have harmful influences on the environment, the property of the contained components is stable, the duration of the heating effect is long, the heating effect can be effectively improved, the heat efficiency of heating can be effectively improved, and metal smelting is facilitated.

Description

technical field [0001] The invention specifically relates to a heating agent for metal smelting and a preparation method thereof, belonging to the field of metal smelting. Background technique [0002] In the process of metal smelting, exothermic agents are sometimes used.
