A refined calculation of the non-stationary temperature walls a rotary kiln is proposed, taking into account thermal conductivity in enclosing and accumulation heat them, intended for use numerical simulation combustion transfer processes. The influence on alternating contact inner surface with gaseous medium layer technological material considered. adequacy method was verified by solution diff...

Catalyst can enhance the reduction effect and promote of vanadium titanomagnetite. In this paper, carbon-containing pellets titanomagnetite were prepared by using highly volatile coal as reducing agent under background a novel process pre-reduction in rotary kiln. The effects CaO, CaCO 3 , B 2 O borax (Na 4 7 ·10H O) on tail gas characteristics prereduction studied simulated kiln flue analyzer....
