Choice of blast melting conditions with combined blowing and estimation of the parameters of tuyere zones

摘要

Possibility of efficient realization of calculated conditions of blast furnace melting with blowing enrichment by oxygen up to 40 percent is substantiated on the base of generalized parameters of tuyere zones, such as complete power of combined blowing and complete power of tuyere gas flow. It was established that complete power of combined bowing and connected dimensions of burning zone decrease slightly, and complete power of tuyere gas flow and connected depth of gas penetration to the hearth center increase.
