Mathematical modelling of rotary-heart furnace

Rotary-heart furnace serves for heating steel semi products before tube rolling. This furnace belongs between industry furnaces with a bigger consumption of fuel. Also, the building and reconstruction furnace is expensive. One way as apply unbiased judgement effectiveness of investment design furnace appears mathematical modelling. Therefore, in this paper is briefly described the mathematical dynamical model of rotary-heart furnace and simulation cases. The parametric study results indicated that partial an exchange of the current a cylindrical barrel by a hanging roof a little deteriorates effectiveness and un-uniformity of heated steel charge.
