More Information
Summary:The invention provides a preparation method of a high-performance ultralow-carbon magnesia-carbon material, and belongs to the technical field of preparation of refractory materials for ferrous metallurgy. The method is characterized by replacing traditional natural graphite with a nanocarbon source and comprising the following steps: fully uniformly mixing SiO2 based natural mineral or slag and the nanocarbon source; transferring into a high-temperature furnace; synthesizing silicon carbide-oxide composite powder under an inert atmosphere; adding the silicon carbide-oxide composite powder toan ultralow magnesia-carbon raw material based on certain mixing ratio, and fully mixing; forming, drying and thermally processing under high temperature to obtain nanocarbon source and silicon carbide-oxide composite powder modified ultralow magnesia-carbon crucible and brick materials; performing slag resisting test according to a static crucible method; testing the thermal shock resistance by using a thermal shock test
