Abstract

The invention provides an input material and a casting method. When continuous casting is applied to high aluminum steel, the input material containing a first composition with an SiO2 component and asecond composition with a C component is applied to the top of continuous casting powder, so that heat preservation for molten steel is achieved and degeneration of continuous casting powder can be suppressed and prevented.

Description

technical field [0001] The present invention relates to an input material and a casting method using the same. More specifically, it relates to an input material capable of improving the quality and productivity of cast slabs by suppressing and preventing denaturation of continuous casting mold fluxes and a casting method using the same. Background technique [0002] In the iron and steel industry, the continuous casting method is superior in quality uniformity and error rate compared to the conventional briquetting method. For this reason, many studies have been carried out on the operation equipment and operation technology of the continuous casting method. As a result, almost all types of steel, including high-alloy steels, can be produced by continuous casting. [0003] The working equipment used for the above-mentioned continuous casting method is called continuous casting equipment. Continuous casting equipment includes: ladle (Ladle), which transports refined molten...
