Abstract

um aparelho e um processo para a produção em alta capacidade de pós de alta pureza de um fio ou haste de grande diâmetro utilizando uma combinação de maçaricos de plasma e aquecimento por indução são apresentados. o processo proporciona uma produtividade superior, por incorporar um sistema de pré-aquecimento indutivo mais eficaz. um mecanismo também é incluído no aparelho, que permite ajustar a posição dos maçaricos de plasma e seu ângulo de ataque com relação ao fio, que tem um efeito direto sobre a transferência mecânica e térmica de energia da pluma de plasma para o fio, permitindo um controle fino sobre a distribuição de tamanho de partícula bem como a capacidade de produção. além disso, variar a frequência de indução permite a otimização do perfil de temperatura dentro do fio, que pode ser diretamente correlacionada com o tamanho médio de partícula resultante.
