Abstract
fornecer um método de resfriamento para aço em tira em um forno de liga que possa estabelecer tanto produtividade quanto qualidade, enquanto resfria por neblina o aço em tira em uma zona de resfriamento em um forno de liga. neblina é aspergida no aço em tira que passa através do equipamento de resfriamento, de modo que a quantidade de neblina aspergida nas partes de borda, na direção de largura do aço em tira, seja menor do que a quantidade de neblina aspergida na parte central para a quantidade de aspersão de neblina aspergida no aço em tira que passa através do equipamento de resfriamento por meio de equipamento de resfriamento ajustado fornecido no lado a montante, na direção de passagem de tira através do equipamento de resfriamento. pelo menos parte da neblina aspergida no aço em tira é sugada por equipamento de sucção de neblina fornecido no equipamento de resfriamento, pelo menos no lado a jusante, na direção da passagem da tira. o aço em tira é resfriado a uma velocidade de passagem de tira, de modo que, entre o início do resfriamento e o fim do resfriamento do aço em tira, a temperatura do aço em tira esteja em uma faixa de temperatura de ebulição de película, e a temperatura da parte de borda seja uma temperatura igual ou maior do que a temperatura da parte central, na direção da largura do aço em tira, em uma faixa de pelo menos 2/3 ou mais da extremidade a montante, na direção de passagem de tira do comprimento de resfriamento total do equipamento de resfriamento.
