Abstract
The article presents the analysis of the forces acting on a coke packing or coal fuel nozzle into the cupola by replacing coke with anthracite and lean coal. The obtained data allow estimating preliminarily in size and shape of burden pieces a probable forecast of cupola melting behavior. The conclusion is that by the transition to the marks of coals to increase the frictional force on the wall of charge, the charge itself must be carefully carve into minimum pieces, which reduces drastically the angle of the engagement and consequently the angle of internal friction coefficient increases as well as the pressure on the side wall of the shaft.
