    • There is disclosed a plant for treating and melting metals, metal compounds and/or metal alloys or for producing calcium carbide. It includes a burden-receiving shaft and a melting furnace arranged below the shaft and including a heating means. A passage opening is provided between the shaft and the melting furnace, which passage opening serves to introduce the burden present within the shaft into the melting furnace.In order to be able to introduce the hot burden into the melting furnace without difficulties and without operational failures due to charging means, a gas-permeable supporting plate rigidly arranged on the melting furnace is provided at the passage opening, corresponding to at least the shaft cross section by its cross section. A clearance is provided beside the supporting plate. The shaft is designed as a structural unit separate from the melting furnace. The shaft and the melting furnace are relatively movable with respect to each other in the direction of the clearance and back.
    • 公开了一种用于处理和熔化金属,金属化合物和/或金属合金或用于生产碳化钙的设备。 它包括设置在轴下方并包括加热装置的承重轴和熔炉。 在轴和熔炉之间设有通道开口,该通道开口用于将轴内存在的负担引入熔化炉。 为了能够无困难地将热负荷引入熔融炉,由于充电装置不会造成操作故障,在通道开口处设置有刚性地布置在熔化炉上的透气性支撑板,至少对应于轴 截面由其横截面。 在支撑板旁边设有间隙。 轴设计为与熔炉分离的结构单元。 轴和熔炉相对于间隙和背部的方向可相对移动。
