Description
Technical field
A kind of carbon cathode blocks preheating device of gas heating, be related to it is a kind of for aluminium electroloysis in phosphorus pig iron casting external genitalia
The preheating of pole carbon block group, especially with the preheating device of the carbon cathode blocks of gas heating.
Background technology
Cathode carbon pieces and rod iron combination are bonded by the way of paste is pricked more, but the bonding mode resistance is big, operation energy consumption
It is high.
Twentieth century end, successively develops carbon cathode blocks phosphorus pig iron casting technology both at home and abroad, and the technology mainly first will
Cathode carbon pieces and rod iron are preheating to certain temperature, then with the phosphorus pig iron molten iron casting of fusing to cathode carbon pieces and rod iron gap,
Cathode sets are formed after cooled and solidified.Wherein cathode carbon pieces and rod iron preheating are placed in resistance furnace, pass through resistance furnace liter
Temperature heats to cathode carbon pieces and rod iron；Or be powered and heated to rod iron two, heat transfer caused by rod iron gives negative electrode charcoal
Block.All it is to be preheated by electrically heated mode to cathode carbon pieces and rod iron above, all in all effect is undesirable.Main cause is
Preheating temperature is relatively low（Less than 500 DEG C）When electrical heating temperature is uneven, the temperature difference is larger, phosphorus pig iron casting when carbon block it is easy to crack；Rise
High preheating temperature（More than 500 DEG C）Electrical heating temperature difference is relatively small, but cathode carbon pieces and rod iron are oxidizable, need atmosphere protection
Heating, adds production cost and reduces production capacity.
The content of the invention
The purpose of the present invention is aiming at insufficient existing for above-mentioned prior art, there is provided a kind of heating-up temperature is uniform, takes out
Easy to operate, achievable higher temperature heating（500-800℃）And prevent the moon of cathode carbon pieces and the gas heating of rod iron oxidation
Pole carbon block group preheating device.
The purpose of the present invention is achieved through the following technical solutions.
The carbon cathode blocks preheating device of a kind of gas heating, it is characterised in that its structure includes：
Heating kiln, the heating kiln are channel-type gas heating kiln, are provided with burner on heating kiln body two side, are heating
Track is provided with kiln body, bottom is provided with recessed discharge flue in heating kiln body；
Carbon cathode blocks motorcycle, the trailer are the flat motorcycle for the track operation being provided with heating kiln body.
The carbon cathode blocks preheating device of a kind of gas heating of the present invention, it is characterised in that described burner is some
It is individual, it is staggered in kiln body both sides.
The carbon cathode blocks preheating device of a kind of gas heating of the present invention, it is characterised in that described heating kiln, it adds
Hot temperature is 500-800 DEG C.
The carbon cathode blocks preheating device of a kind of gas heating of the present invention, it is characterised in that described burner enters combustion
Tracheae couples with gas pipeline；The incoming air conduit of burner couples with air supply duct；Electricity is respectively arranged with air-supply, gas pipeline
Magnet valve, magnetic valve connect with control system.
A kind of carbon cathode blocks preheating device of gas heating of the present invention, higher temperature heating can be achieved（500-800
℃）, temperature uniformly and prevent cathode carbon pieces and rod iron from aoxidizing, realize that various cell lines are poured with the carbon cathode blocks phosphorus pig iron
Preheating requirement is cast, heating-up temperature is uniform, it is easy to operate to take out.
Brief description of the drawings
Fig. 1 is the structural representation of the present invention.
Embodiment
A kind of carbon cathode blocks preheating device of gas heating, its structure include：Heating kiln 1, the heating kiln are channel-type
Gas heating kiln, be provided with burner 2 on heating kiln body two side, track 3 be provided with heating kiln body, in heating kiln body under
Bottom is provided with recessed discharge flue 4；Carbon cathode blocks motorcycle 5, the trailer are the flat of the track operation that is provided with heating kiln body
Board-like motorcycle.Described burner is several, is staggered in kiln body both sides；Described heating kiln, its heating-up temperature are
500-800℃；The Gas Pipe of entering of described burner couples with gas pipeline 6；The incoming air conduit of burner and air supply duct 7
Connect；Magnetic valve is respectively arranged with air-supply, gas pipeline, magnetic valve and control system 8 connect.
A kind of carbon cathode blocks preheating device of gas heating of the present invention, can manually or automatically be controlled by control system
The heating cycle of burner processed and combustion gas, air stoichiometry, to ensure temperature homogeneity in kiln body and atmosphere as reproducibility gas
Atmosphere, the gas in kiln body are discharged by exit flue.During operation, by carbon cathode blocks（Including cathode carbon pieces 9 and rod iron 10, under
Together）It is positioned in motorcycle, motorcycle passes in and out kiln body by track, is sent into cold cathode carbon block group or takes out the cathode carbon pieces after preheating
Group.Its burner is staggered in kiln body both sides, beneficial to the circulation of kiln body interior air-flow, realize kiln body temperature uniformly, one
Cause.Burner is connected to air, gas pipeline, is respectively arranged with magnetic valve on pipeline, and the magnetic valve is respectively and control
System connects；Control system can control air, gas proportioning, and gas is reducing atmosphere after making burning, after the burning
Reducibility gas heats to cathode sets, prevents its oxidation；Control system, which can be realized, controls/automatically controls manually conversion.It can be achieved
Higher temperature heats（500-800℃）, temperature uniformly and prevent cathode carbon pieces and rod iron from aoxidizing, realize various cell lines
With carbon cathode blocks phosphorus pig iron casting preheating requirement.
