More Information
Summary:The invention relates to a preparation method and proportion of components of a low-carbon magnesium-calcium carbon brick for manufacturing an inner lining of a steel-making refining furnace. In the invention, electro-fused or sintered magnesium-calcium powder, magnesia micro-powder, nano-carbon block, graphite, an antioxidant and a binding agent are mainly adopted as main components for proportioning, the carbon content in the components is lower than 5%, and a finished product can be prepared by controlling the components of raw materials and the grain size, and carrying out mixing, molding and heat treatment. The product is conductive to smelting of low-carbon steel and can smelt high-quality pure steel and clean steel and overcome the problems of environmental pollution and shortage of resources caused by using magnesium-chromium bricks for the inner lining of the refining furnace.
