Comparison of calculatings methods of the main parameters for single-tier tuyeres

Abstract

A large number of articles have been devoted to the problem of calculation of main parameters for single-tier tuyeres. Various methods and equations on the matter have been proposed in the papers. However, they do not provide the necessary information which of these methods allows the obtaining of the main design parameters of single-tier tuyere, which will correspond to the existing standard structures, i.e. will be adapted to modern working conditions of national iron-and-steel enterprises of Ukraine. The creation of above-mentioned methods of calculation is an important question, as it will contribute to the development of more advanced single-tier tuyeres. Five methods have been developed for calculation of the main design parameters of single-tier tuyeres. Appropriate analytical and computational research was conducted using these five methods. It was found that the approximate comparison results of the modern main design parameters of single-tier tuyere on the converters of National iron-and-steel enterprises of Ukraine can be obtained by methods one and four. However, the method four requires some additional graphs which can complicate the development of the calculation program for this method.
