It is established that the main constructive parameters primarily include those that provide the construction of purge units. Determined the main constructive parameters for single-tier and for the first time multi-tier tuyeres. The analysis of calculation methods for calculatio and determining the constructive parameters of the upper tuyeres. is carried out. From which it follows that depending on the approach to the calculation, we can distinguish three groups of techniques. Five methods of calculation of the basic constructive parameters of the upper tuyeres are formed on the basis of the considered literature sources. Methods have characteristic features in the proposed algorithm and meet the requirements of the goal and objectives in the work. From which the most appropriate method that will facilitate the performance of the work was selected in the course of analytical and calculation research.It is established that there is no methodic or algorithm of equations that allow to determine all the necessary main constructive parameters for the calculations of multi-tier tuyeres The established of the method and algorithm of calculation for the main constructive parameters of multi-tier tuyeres. According to this, many statistical calculations were performed in the software environment with generalization and analysis of the information obtained. The world's first National Methodology for Determining the Basic Structural Parameters of Multilevel Tuyeres has been developed. The method provides: a unit for calculating the distribution of blasting costs and the main design parameters of the main purge unit of a multilevel lance according to an algorithm of 34 formulas.
