O calc\u00e1rio calc\u00edtico \u00e9 utilizado no processo de fabrica\u00e7\u00e3o do ferro para produzir a esc\u00f3ria, que remove as impurezas do min\u00e9rio enquanto produz gusa l\u00edquido. \u00c9 adicionado ao s\u00ednter e pelotas de ferro para auxiliar o fluxo e promover a aglomera\u00e7\u00e3o em seus produtos. Os altos-fornos podem adicionar calc\u00e1rio calc\u00edtico diretamente \u00e0 carga de ferro para formar a esc\u00f3ria e proteger o refrat\u00e1rio.<\/p>

Fornecemos o calc\u00e1rio calc\u00edtico em diversas granulometrias, conforme a necessidade do cliente.<\/p>

    O calc\u00e1rio calc\u00edtico (CaCO3) \u00e9 adicionado \u00e0 carga do alto-forno, onde, sob altas temperaturas, se decomp\u00f5e formando \u00f3xido de
    c\u00e1lcio (CaO) reagindo com as impurezas presentes no min\u00e9rio de ferro, como s\u00edlica (SiO2), alumina (Al2O3) e outros elementos
    indesej\u00e1veis, formando a esc\u00f3ria. O calc\u00e1rio \u00e9 essencial para melhorar a fluidez da esc\u00f3ria, facilitando a remo\u00e7\u00e3o das impurezas
    do ferro gusa. Quando utilizado corretamente, o calc\u00e1rio contribui para a produ\u00e7\u00e3o de ferro gusa de melhor qualidade, com menor quantidade de elementos indesej\u00e1veis, o que \u00e9 fundamental para a fabrica\u00e7\u00e3o de a\u00e7o e outros produtos derivados.<\/p>

    O calc\u00e1rio da Sandra Minera\u00e7\u00e3o possui elevado teor de CaCO3 e teores extremamente baixos de s\u00edlica (SiO2) e enxofre (S),
    oferecendo a faixa granulom\u00e9trica mais adequada para otimizar o desempenho do seu alto-forno<\/p>\t\t\t\t\t\t\t\t<\/div>\n\t\t\t\t<\/div>\n\t\t\t\t\t<\/div>\n\t\t<\/div>\n\t\t\t\t\t<\/div>\n\t\t<\/section>\n\t\t\t\t

    No processo de sinteriza\u00e7\u00e3o, o calc\u00e1rio calc\u00edtico, al\u00e9m de auxiliar na aglomera\u00e7\u00e3o das part\u00edculas, favorece a fus\u00e3o da mistura ao
    reduzir o ponto de fus\u00e3o do min\u00e9rio de ferro. Dessa forma, contribui para a forma\u00e7\u00e3o de um s\u00ednter poroso, ideal para ser
    alimentado no alto-forno.<\/p>

    Nossa capacidade de produ\u00e7\u00e3o e fluxo de processo possibilitam a fabrica\u00e7\u00e3o do perfil granulom\u00e9trico adequado, garantindo o
    melhor desempenho e a permeabilidade do leito nas m\u00e1quinas de sinteriza\u00e7\u00e3o.<\/p>\t\t\t\t\t\t\t\t<\/div>\n\t\t\t\t<\/div>\n\t\t\t\t\t<\/div>\n\t\t<\/div>\n\t\t\t\t\t<\/div>\n\t\t<\/section>\n\t\t\t\t<\/div>","protected":false},"excerpt":{"rendered":"
