Description

Technical Field

[0001] The utility model relates to the technical field of smelting equipment, in particular to a water jacket device for a fuming furnace. Background Art

[0002] The fuming furnace is a reduction smelting furnace that uses blasting to blow coal foam into zinc-containing molten slag for reduction, producing zinc oxide and water-quenched slag. The furnace body is mainly composed of a water jacket, furnace bricks and a wind jacket core. The coal-spraying wind jacket core in the tuyere water jacket is 20 cm away from the bottom furnace brick. During the smelting process, blasting and violent reactions cause the molten hot slag to boil and roll above the furnace bricks, causing serious scouring of the furnace bricks. The average service life is 3 months, which is short, affecting the continuous production of the "three-continuous furnace" and increasing production costs.
