The preheating device is characterized by structurally comprising a heating kiln and a cathode carbon block set trolley, the heating kiln is a channel type fuel gas heating kiln, combustion nozzles are arranged on the two side walls of a heating kiln body, a rail is arranged in the heating kiln body, and a downward-concave smoke outlet channel is arranged at the lower bottom in the heating kiln body; and the cathode carbon block set trolley is a flat plate type trolley running on the rail arranged in the heating kiln body. According to the cathode carbon block set preheating device for performing heating through fuel gas, the high-temperature heating (500-800 DEG C) can be achieved, the temperature is even, oxidation of cathode carbon blocks and steel bars is prevented, the requirement for casting preheating of cathode carbon block set phosphorous pig iron for various cell lines is met, the heating temperature is even, and the operation of taking out is convenient.
Description
Technical field
A carbon cathode blocks primary heater unit for gas heating, relates to a kind of preheating of carbon cathode blocks before phosphorus pig iron casting for electrolysis of aluminum, particularly uses the primary heater unit of the carbon cathode blocks of gas heating.
Background technology
Cathode carbon pieces and the rod iron combination mode of pricking paste that adopts bond more, but this bonding mode resistance is large, operation energy consumption is high.
Twentieth century end, domestic and international priority develops carbon cathode blocks phosphorus pig iron casting technology, cathode carbon pieces and rod iron are mainly first preheating to certain temperature by this technology, then are poured into cathode carbon pieces and rod iron gap with the phosphorus pig iron molten iron of fusing, form cathode sets after cooled and solidified.Wherein cathode carbon pieces and rod iron preheating are positioned in resistance furnace, heat up to cathode carbon pieces and rod iron heating by resistance furnace; Or heat to the energising of rod iron two, the heat that rod iron produces passes to cathode carbon pieces.Below be all that all in all effect is undesirable by electrically heated mode to cathode carbon pieces and rod iron preheating.When major cause is preheating temperature lower (less than 500 DEG C), during uneven, the temperature difference of electrical heating temperature comparatively large, phosphorus pig iron casting, charcoal block is easy to crack; Raise preheating temperature (more than 500 DEG C) electrical heating temperature difference relatively little, but cathode carbon pieces and rod iron oxidizable, need atmosphere protection to heat, add production cost and reduce production capacity.
Summary of the invention
Object of the present invention is exactly the deficiency existed for above-mentioned prior art, provide a kind of Heating temperature evenly, take out easy to operate, comparatively high temps heating (500-800 DEG C) can be realized and prevent the carbon cathode blocks primary heater unit of the gas heating of cathode carbon pieces and rod iron oxidation.
The object of the invention is to be achieved through the following technical solutions.
A carbon cathode blocks primary heater unit for gas heating, is characterized in that its structure comprises:
