Multipurpose tilting furnace of spherical molten pool and manufacturing method thereof

Abstract

The invention relates to a multipurpose tilting furnace of a spherical molten pool. A furnace body is fixed on a furnace bottom beam frame, one end of the furnace bottom beam frame is connected with a pedestal hinge, and the other end of the furnace bottom beam frame is connected with the pedestal through a hydraulic oil cylinder; the furnace body comprises a furnace body housing, a furnace bottom ramming layer is arranged inside the furnace body housing, a hemispheric molten pool is built on the furnace bottom ramming layer, and a water jacket furnace mouth communicated with the hemispheric molten pool is arranged on the upper part of one side of the furnace body housing corresponding to the pedestal hinge; a furnace cover comprises a furnace cover housing, a ring-shaped arched angle brick is built on the bottom of the furnace cover housing, a spherical-crown-shaped vault is built on the ring-shaped arched angle brick, a flaming nozzle is arranged at the central portion of the spherical-crown-shaped vault to be communicated with the molten pool in the furnace body, and a furnace top insulation layer is casted on the spherical-crown-shaped vault; and the furnace cover is connected with the furnace body through an elastic coupling bolt, a smoke hood is arranged above the water jacket furnace mouth corresponding to the furnace body, a side smoke pipe is arranged at one side of the smoke hood, and the other end of the side smoke pipe extends to the position of the shaft axis of the pedestal hinge and sleeved with an external smoke pipe through a right-angled bend.

Description

technical field [0001] The invention relates to a lead-antimony alloy refining furnace for smelting non-ferrous metals, in particular to a multipurpose tilting furnace with a spherical melting pool. Background technique [0002] In the non-ferrous smelting industry, the refining process of crude lead-antimony alloy to remove impurities such as copper, tin, arsenic, and iron is generally carried out in an indirectly heated iron pot. It will form eutectic alloy with iron when the temperature is higher than 650°C, and the iron pot is fragile and unsuitable; at this time, the reverberatory furnace can generally be selected for refining, but the reverberatory furnace is not flexible enough to discharge materials, and the more important thing is the crude lead-antimony alloy The refining cycle is short, the temperature of the furnace heats up and cools rapidly, changes frequently, and the heat stress of the reverberatory furnace is uneven, which easily leads to damage to the struc...

[0002] In the non-ferrous smelting industry, the refining process of crude lead-antimony alloy to remove impurities such as copper, tin, arsenic, and iron is generally carried out in an indirectly heated iron pot. It will form eutectic alloy with iron when the temperature is higher than 650°C, and the iron pot is fragile and unsuitable; at this time, the reverberatory furnace can generally be selected for refining, but the reverberatory furnace is not flexible enough to discharge materials, and the more important thing is the crude lead-antimony alloy The refining cycle is short, the temperature of the furnace heats up and cools rapidly, changes frequently, and the heat stress of the reverberatory furnace is unbalanced, which easily leads to damage to the structure of the furnace body

[0003] The well-known cylindrical converter is convenient for feeding and discharging materials, and the thermal stress is balanced. It is suitable for copper matte self-heating blowing and blister copper refining, but the cost is high; the traditional tilting reverberatory furnace is convenient for feeding and discharging materials, but its structure is complex and its resistance to rapid heat and rapid cooling is poor. , are not suitable for the refining of crude lead antimony alloy
