Process for cleaning inductor channels of furnaces melting non-ferrous metal alloys

摘要

A process cleans inductor channels of furnaces melting non-ferrous metal alloys wherein the coating alloy has a minimum of zinc content of 50% by weight which is subject to softening, dilution and floating of DROSS heavy slag which obstructs the inductor channels. The slag is removed by mechanical action of hammer-shock powered lances with slicing fins presented at a contact end of the lances. Cleaning of the slag is aided by a nitrogen gas stream acting within inductor channels.
