Instalado na sec\u00e7\u00e3o de fundi\u00e7\u00e3o, remove rapidamente o calor do fundido polim\u00e9rico e ajuda a formar uma chapa-m\u00e3e est\u00e1vel antes do estiramento longitudinal ou biaxial. Como a precis\u00e3o da chapa fundida afeta diretamente a qualidade da pel\u00edcula a jusante, s\u00e3o essenciais uma uniformidade t\u00e9rmica fi\u00e1vel, um bom acabamento superficial e estabilidade rotacional.<\/p>\n<p>O rolo de arrefecimento JWELL utiliza um canal de fluxo espiral alternado de di\u00e2metro vari\u00e1vel para melhorar a circula\u00e7\u00e3o interna, a efici\u00eancia da transfer\u00eancia t\u00e9rmica e a resposta do controlo da temperatura. A temperatura da superf\u00edcie do rolo pode ser controlada com uma precis\u00e3o de \u00b10.5\u00b0C, contribuindo para um arrefecimento consistente ao longo da face de trabalho. De acordo com os dados do produto, a atualiza\u00e7\u00e3o para esta conce\u00e7\u00e3o de rolo pode aumentar a efici\u00eancia de fundi\u00e7\u00e3o em 20%\u201330%.<\/p>\n<p>Para um funcionamento est\u00e1vel a alta velocidade, cada rolo de fundi\u00e7\u00e3o recebe uma corre\u00e7\u00e3o de equilibragem din\u00e2mica de alta precis\u00e3o. O acabamento de superf\u00edcie espelhada proporciona a superf\u00edcie de trabalho lisa necess\u00e1ria para aplica\u00e7\u00f5es exigentes de pel\u00edcula, enquanto o tratamento anticorrosivo protege o canal de fluxo espiral interno. Os rolos podem ser fornecidos com um di\u00e2metro m\u00e1ximo de 1600 mm para corresponder a diferentes disposi\u00e7\u00f5es e requisitos de processo das linhas de pel\u00edcula.<\/p>\n<p>Este rolo de arrefecimento \u00e9 adequado \u00e0 etapa de fundi\u00e7\u00e3o da chapa-m\u00e3e em linhas de estiramento biaxial e longitudinal.
