Abstract (en)

[origin: WO9927144A1] The present invention relates to an operation method of furnace equipment for magnesium alloys, wherein a bath surface is covered with a protection gas containing a sulphur compound. The purpose of this invention is to reduce the production costs and the damage to the environment as well as to ensure a particularly safe operation when handling magnesium liquid baths. To this end, the protection gas consists in a mixture of SO2 with an inert gas, wherein the proportion by volumes of SO2 is set at a precise value in a range of between 0.3 % and 1.5 %, preferably of between 0.5 % and 1.0 %.
