O revestimento do rolo tem apenas 50%\u201370% da espessura de um rolo padr\u00e3o. Ao minimizar a \u00e1rea de contacto do suporte interno e aumentar a \u00e1rea de contacto com a \u00e1gua de arrefecimento, a conce\u00e7\u00e3o transfere o calor com maior efici\u00eancia e ajuda a estabilizar as condi\u00e7\u00f5es de processamento.<\/p>\n<p>Uma estrutura integrada de canais circulares compensa a espessura reduzida do revestimento e aumenta a resist\u00eancia \u00e0 press\u00e3o. Nas mesmas condi\u00e7\u00f5es de funcionamento, este rolo de calandra de alta efici\u00eancia pode aumentar a produ\u00e7\u00e3o das linhas de placas e chapas em 20%\u201350%, tornando-se uma atualiza\u00e7\u00e3o pr\u00e1tica para fabricantes que procuram maior produtividade sem alterar todo o processo de extrus\u00e3o.<\/p>\n<p>O rolo \u00e9 temperado e revenido para criar uma estrutura interna densa e est\u00e1vel. A t\u00eampera profunda da superf\u00edcie exterior atinge HRC 55\u201358, enquanto a cromagem eletrol\u00edtica dura pode aumentar a dureza superficial para HRC 60\u201362, melhorando a resist\u00eancia ao desgaste e a vida \u00fatil. Est\u00e3o dispon\u00edveis retifica\u00e7\u00e3o e polimento de precis\u00e3o para acabamentos espelhados e superespelhados.
