Abstract

The invention relates to a reflecting furnace for smelting tin lead materials, belonging to smelting equipment. The reflecting furnace is mainly composed of a furnace hearth (1), a furnace bottom smelting tank (2), a furnace wall (3) and a furnace top (4), wherein the furnace bottom smelting tank (2) is positioned below the furnace hearth (1), and a low fire baffle wall (6) is arranged between a fire chamber (5) in the furnace wall and the furnace hearth (1). A slag discharging opening (12) for discharging tin lead alloy is arranged on one side wall of the furnace near the position of a furnace tail, two working doors (13, 14) are arranged on the other side wall of the furnace, a smoke outlet (15) is arranged on the furnace wall at the tail part, and a charging opening (16) is arranged on the furnace top (4). The arc shape of the furnace top on the low fire baffle wall (6) is shown to press down towards the two sides; the position of the furnace top to the furnace hearth (1) is horizontal, and the position of the furnace top to the furnace tail is pressed towards the furnace tail in an inclined manner. The reflecting furnace has the advantages of high heat efficiency, quick material smelting, low cost and less coal consumption with the coal combustion rate of 42 to 48%.

Description

technical field [0001] The invention relates to a reverberatory furnace for smelting tin-lead materials, belonging to smelting equipment. Background technique [0002] Existing 6m 2 The reverberatory furnace is mainly designed for smelting lead-containing materials produced by the silver series. The fuel is diesel oil; the depth of the molten pool is large; the fire wall of the furnace is high; Tin-rich dross produced during lead refining.
