Latest Patents

Shiota holds a patent for a "Method for producing low-carbon ferromanganese." This method allows for a high manganese yield while producing low-carbon ferromanganese. The process involves blowing an oxidizing gas from a top-blowing lance onto a bath face of high-carbon ferromanganese molten metal. The reaction vessel is equipped with both a top-blowing lance and a bottom-blowing tuyere to facilitate decarburization. The slag composition is carefully adjusted to maintain a specific ratio of (CaO+MgO)/(AlO+SiO) between 0.4 and 5.0. Additionally, the method requires agitation under conditions where the agitation power density of the gas blown through the bottom-blowing tuyere is not less than 500 W/t.
