Para garantir a opera\u00e7\u00e3o segura e prolongar a vida \u00fatil do equipamento, recomendamos limitar o uso de PBN a temperaturas n\u00e3o superiores a 1300 \u00b0C, com uma taxa de resfriamento controlada de menos de 25 \u00b0C por minuto abaixo de 660 \u00b0C. O cadinho deve ser inspecionado entre cada uso e substitu\u00eddo imediatamente se forem detectados quaisquer sinais de rachaduras.<\/strong><\/p>","protected":false},"excerpt":{"rendered":"
