This products +improve their final properties through a reheating operation [@Ta2018]. +The reheating operation is typically done on direct-fired furnaces where +steelworks gases are combusted with excess air +[@Young2016; @Korousic1996; @Gouveia2013]. + +The high-temperature, gas atmosphere and steel's chemistry lead to +oxidation and decarburization of the steel +[@Gouveia2013; @Tao2014; @Young2016]. Specifically, the decarburization +is defined as the diffusion mechanism of the metal's carbon from the +inner to outer zone replacing the lost carbon during the redox +[@Young2016]; however, the decarburization becomes greater at +high-temperature [@Gouveia2013]. Therefore, a none controlled reheating +operation will produce material losses and depreciation on product +quality [@Liu2018Numerical]. Then, a common way to establish the final +product quality is by measuring the coating or decarburated layer +[@Liu2018Numerical; @Alvarenga2015; @Zhao2016a]. This has be done by +several methods and systems mainly validated by optical microscope (OM) +techniques [@Tao2014; @Suarez2008; @Zhao2016a]. Nevertheless, the +optical measurement-data were only based in few representative data; no +more than five measurements [@Chen2020]. + +The E1077-01 "Standard Test Methods for Estimating the Depth of +Decarburization of Steel Specimens". Proposes to make a number of random +measurements around the specimen periphery, at randomly selected +locations. If statistical precision is required, it suggests considering +95% of confident limits, mean and standard deviation; letting the number +of measurements open, according to the desired accuracy. Thus, the +present paper introduces a new approach to measure the decarburization +depth based on image processing analysis. -some text in the Readme file.
