Rotary kiln 101 has the first charging aperture, calcining outlet and burner installing port, and this burner is located at this burner installing port. Electric furnace 102 has the second charging aperture, puts ferrum mouth, slag tap and exhanst gas outlet.One end of hot material conveying device 103 and this roasting Sand outlet is connected, and the other end of hot material conveying device 103 is connected with this second charging aperture.
It is briefly described the vanadium titano-magnetite according to this utility model embodiment or ilmenite reduction smelting system below with reference to Fig. 1 The work process of 10.
First, the vanadium titano-magnetite after magnetic separation or ilmenite are joined revolution from the first charging aperture by a certain percentage with reducing agent In kiln 101, and utilize burner jet flames in rotary kiln 101, in order to the vanadium titano-magnetite in rotary kiln 101 or titanium Iron mine carries out prereduction and obtains calcining;
Utilize hot material conveying device 103 by calcine trans-portation to electric furnace 102, and utilize electric furnace 102 to reduce further. The vanadium-bearing hot metal produced or molten iron are released from putting ferrum mouth, and the slag containing titanium dioxide of generation is released from slag tap, generation Flue gas containing carbon monoxide is released from exhanst gas outlet.
Vanadium titano-magnetite according to this utility model embodiment or ilmenite reduction smelting system 10 are by utilizing rotary kiln 101 right Vanadium titano-magnetite or ilmenite after magnetic separation carry out prereduction, such that it is able to utilize rotary kiln 101 pre-reduction treatment ore deposit fully Stone ability is big, it is easily controllable to reduce, equipment can realize features such as maximizing, equipment operating is reliable.
Vanadium titano-magnetite according to this utility model embodiment or ilmenite reduction smelting system 10 are by utilizing electric furnace 102 to roasting Sand carries out drastic reduction, such that it is able to utilize fully electric furnace 102 thermal efficiency height, good leak tightness, equipment enlarging power big, Disposal ability greatly, easily realize scale, be prone to mate with rotary kiln 101, service life of equipment length, operating rate are high, operation Convenient, molten point of metal recovery rate high.
The calcining " hot charging heat fortune " being additionally, since rotary kiln 101 output adds electric furnace 102, greatly reduces unit calcining Power consumption, reduces electric energy.
Therefore, according to the vanadium titano-magnetite of this utility model embodiment or ilmenite reduction smelting system 10 have disposal ability big, Operating cost is low, low power consumption and other advantages.
As it is shown in figure 1, according to the vanadium titano-magnetite of this utility model embodiment or ilmenite reduction smelting system 10 include for Prereduction is through the vanadium titano-magnetite of magnetic separation or the rotary kiln 101 of ilmenite, for the kiln intracavity jet flames of rotary kiln 101 Burner (not shown), electric furnace 102 and hot material conveying device 103.
Rotary kiln 101 has the first charging aperture, calcining outlet and burner installing port.Vanadium titano-magnetite after magnetic separation or ilmenite And reducing agent joins in rotary kiln 101 from this first charging aperture by a certain percentage.Wherein, the vanadium titano-magnetite after magnetic separation Or after ilmenite can first be mixed homogeneously with reducing agent, then join in rotary kiln 101 from this first charging aperture.Additionally, magnetic Vanadium titano-magnetite or ilmenite after choosing can also directly join in rotary kiln 101 from this first charging aperture with reducing agent.
