Abstract

MÉTODO DE PREVISÃO DE DUREZA DE TRILHO ENDURECIDO POR CALOR, MÉTODO DE TRATAMENTO TÉRMICO, DISPOSITIVO DE PREVISÃO DE DUREZA, DISPOSITIVO DE TRATAMENTO TÉRMICO, MÉTODO DE FABRICAÇÃO, INSTALAÇÕES DE FABRICAÇÃO, E MÉTODO DE GERAÇÃO DE MODELO DE PREVISÃO DE DUREZA. Tratamento térmico de um trilho tendo uma distribuição de dureza estável é possibilitado. A dureza de um trilho após o trilho tendo uma temperatura igual a ou superior a uma temperatura de região de austenita ser resfriado à força em uma instalação de resfriamento (7) é prevista. Uma pluralidade de conjuntos de dados para aprendizado composta por um conjunto de dados de condição de resfriamento e dados de saída de dureza é adquirida usando um modelo que realiza computação usando um conjunto de dados de condição de resfriamento tendo pelo menos uma temperatura de superfície do trilho antes do início de resfriamento e as condições de operação da instalação de resfriamento (7) como dados de entrada e a dureza dentro do trilho após o resfriamento forçado como dados de saída. Um modelo de previsão de dureza usando o conjunto de dados de condição de resfriamento como pelo menos dados de entrada e informações sobre a dureza dentro do trilho após o resfriamento forçado como dados de saída são gerados antecipadamente por aprendizado de máquina usando a pluralidade de conjuntos de dados adquirida para aprendizado. A dureza do trilho é prevista a partir da dureza dentro do trilho em relação a um conjunto de conjuntos de dados de condição de resfriamento definidos como condições de resfriamento do resfriamento forçado usando o modelo dPe previsão de dureza.
