Beneficial effect, owing to using such scheme, a molten point stove includes that kiln cover is designed as assembly of devices, connect back to rotary kiln, melted mineral aggregate in rotary kiln flows into molten point of stove by kiln cover, coal injection pipe inserts from bell pci port and makes melted mineral aggregate continue heating reduction in cupola well and realize slag sluicing system in stove, after ferroalloy melt accumulates the amount of appraising and deciding, releases and cast alloys ingot iron from putting ferrum mouth.
Described body of heater shell is steel structure, and body of heater connection suitable for reading kiln cover becomes assembly of devices, and kiln cover upper side is connected with seal of rotary kiln.Described kiln cover upper side is provided with rotary kiln coal powder injection hole, can be inserted into coal injection pipe and provides heat energy for rotary kiln；Kiln cover center ovens is covered with coal powder injection hole, can be inserted into oxygen coal jet pipe and provides reduction, insulation heat energy for molten point of stove；Inboard wall of furnace body is lined with refractory material, makes cupola well with refractory material, in order to during mineral aggregate smelting reduction, ferroalloy melt precipitates accumulation in molten bath.
Bell is provided with exhanst gas outlet, and high-temperature flue gas can be made a gift to someone drying system UTILIZATION OF VESIDUAL HEAT IN by this mouthful of derivation；Bell is provided with charge door, can add smelting auxiliary agent at this.
Put ferrum mouth, after ferroalloy melt accumulates the amount of appraising and deciding, release and water cast-iron alloy ingot from putting ferrum mouth.Slag tap, uses siphon slagging, just can flow continually out molten point of stove when slag liquid level is higher than slag tap.
Only need to melt point furnace apparatus and can realize work with kiln cover and seal of rotary kiln composition stove production line.The program is respectively completed the different phase of smelting process, produces continuously, it is achieved slag ferrum isolates, and waters and casts iron ingot.
Advantage: ferroalloy smelting melts point furnace apparatus applies the continuous production processed at lateritic nickel ore, limonite, bloodstone smelting and metal tailings, and technique is simple, solves the production of existing smelting process discontinuous
, the problem such as energy consumption is high, production cost high, environmental protection pressure is big.Fire coal is the energy and reducing agent, reduces smelting cost.
