摘要
The oxygen is an element which has adversely affect to the steel quality because it causes embrittlement at high temperature, evidenced by the increased susceptibility on overheating and the appearance of cracks during deformation plastic, respectively by determining the appearance of the gas holes during castings solidification of products. As a result from a technological point of view, in industrial practice shall be adopted a series of measures that are intended to ensure a low oxygen content (recommended below 40ppm). The paper presents a few practical data taken from the industry in relation to the manner in which it is influenced the content of oxygen according with the vacuum parameters and the steel temperature. The resulting correlations, presented in both form graphical and analytical, are a real benefit to the industry, so can be determined a parameter depending on the other two.
