Description

technical field [0001] The invention relates to the technical field of metallurgical engineering, in particular to a Kaldor furnace hydraulic experiment device. Background technique [0002] At present, the Kaldor furnace is widely used in lead and copper anode slime pyrometallurgy, which has the advantages of large unit processing capacity and excellent kinetic conditions. However, during the smelting process of the Kaldor furnace, the slag-gold two-phase melt in the furnace is very easy to form splashes under the synergistic effect of the high-pressure airflow of the air spray gun and the uniform rotation of the furnace body, and continuously scours the furnace wall to damage the furnace lining; at the same time, some The fine spatter forms soot under the action of flue gas entrainment, which reduces the yield of precious metals and directly affects the economic benefits of the Kaldor furnace smelting process. [0003] Melt splashing is the external manifestation of the f...

Problems solved by technology

However, the smelting process in the Kaldor furnace is a high-temperature (>1000°C) multi-phase physical and chemical reaction heat and mass transfer process, and it is difficult to find out the relationship between the dynamic fluctuation behavior of the slag-gold two-phase melt liquid level and the position of the spray gun, the size of the spray gun and the gas flow through conventional experimental means. Intrinsic relationship between flow rate and other process parameters

The determination of process parameters in the production process mainly relies on manual experience, and there are often problems such as large errors and low control precision. It is urgent to develop an experimental device that can monitor the motion behavior of the Kaldor furnace melt
