Abstract

dispositivo de medição de proporção de pó, sistema de medição de proporção de pó, método de medição de proporção de pó, programa de computador, alto-forno e método de operação de alto-forno. um dispositivo de medição de proporção de pó é fornecido, que, em processos de operação de um alto-forno, etc., pode medir em tempo real com alta precisão a proporção de pó de pó aderido à superfície do material usado como uma matéria-prima. este dispositivo de medição de proporção de pó 12, que mede a proporção de pó de um pó aderido à superfície de uma substância 26, é fornecido com um dispositivo de iluminação 18 que ilumina a substância 26, um dispositivo espectroscópico 16 que divide a luz refletida da substância 26 e mede a reflectância espectral do mesmo, e um dispositivo de cálculo 22 que, da reflectância espectral em cada posição na superfície da substância medida pelo dispositivo espectroscópico 16, usa pelo menos a reflectância espectral da região onde o pó está aderido, calcula um valor correspondente à área de superfície da região à qual o pó está aderido e calcula a proporção de pó com base no referido valor calculado.
