Abstract
The utility model relates to an aluminium electrolyser with combined SiN and SiC material as side lining brick, characterized in that the side lining brick is made from SiN and SiC material, wherein, the lining brick whose thickness is generally from 30-60 millimetres can be divided into side brick and angle brick. The cross section of the side brick is rectangular, while the cross section of the angle brick is arc-shaped. The seam is bonded by adhesive agent that is high temperature resistant and electrolytes corrosion resistant. The side brick can resist electrolytes corrosion, and is electrically insulated, which eliminates transversal side wall electric current, reduces the secondary loss of aluminium, and enhances current efficiency. Additionally, an ideal and regular furnace chamber is easy to be formed, which makes the operation convenient and provides advantages for continuous feeding and gas cleaning.
Description
The invention belongs to the Aluminium Electrolysis field.
The existing electrolyzer that is used for Aluminium Electrolysis, its side lining lining brick is the carbon piece.In electrolytic process, the sodium Metal 99.5 reaction in this carbon piece and the ionogen generates a kind of composition between C
60Na and C
68The lamellar compound of Na causes the carbon piece to expand.It when fused electrolyte contacts with this side lining carbon piece, produces the lateral sidewalls electric current, thereby strengthens the quadratic loss of aluminium again, reduces current efficiency.In addition, use carbon element side lining, be difficult for forming shape in the burner hearth desirable, that rule are positive in the groove, furnace bottom is easily given birth to crust.
The objective of the invention is, a kind of electrolyzer of new side lining brick is provided, to overcome the above-mentioned shortcoming of carbon element side lining electrolyzer.
The electrolyzer that is used for Aluminium Electrolysis, comprise the soberberg anode type and give roasting anode type, its cell body mainly is made of pot shell, end liner, side lining, end paste, cathode block, cathode steel bar etc., and its principal character is that the lining brick of side lining is the silicon nitride combined silicon carbide material brick.
The thickness of above-mentioned side lining lining brick is preferably the 30-60 millimeter.
To connect convenient and adapt to the pot shell shape in order to build, lining brick can be divided into two kinds of side brick and angle bricks, and the transverse section of side brick is a rectangle, and the transverse section of angle brick is an arc, and its curvature will adapt with the curvature of four jiaos of pot shells.Connect area for increasing to build between lining brick, the block of side brick and angle brick both sides connects face one side can be designed to convex, and opposite side is a spill, and the spill of brick is built the face that connects and connect face with the convex block of adjacent brick and dock.Puzzle joint by high temperature resistant, electrolyte-resistant corrosive caking agent is bonding.
Slit between side lining lining brick and pot shell, but filling aluminum oxide are with the thermal expansion of dashpot liner.
An accompanying drawing specific embodiment of the present invention.Fig. 1 is the cell lining vertical view, and wherein (1) is pot shell, the puzzle joint between (2) side lining brick, the side brick of (3) side lining, the angle brick of (4) side lining, (10) cathode steel bar.Fig. 2 is A---the A sectional view, and wherein (5) are the aluminum oxide of the filling in the slit between side lining brick and the pot shell, stuck with paste the end of for (6), (7) cathode block, (3) side brick, (8) refractory brick, (9) refractory concrete, (10) cathode steel bar, (11) insulating brick, (12) end liner, Fig. 3 are side brick vertical view, wherein (13) build the face that connects for its convex, and (16) build the face that connects for its spill.Fig. 4 is the angle brick vertical view, and wherein (14) build the face that connects for spill, and (15) build the face that connects for convex.
Make the cell sidelining brick with silicon nitride combined silicon carbide material, can resist electrolyte corrosion, not Formed, sodium compound, thus avoid the expansion of side lining. Owing to eliminated the lateral sidewalls electric current, reduce the quadratic loss of aluminium, improve current efficiency. In addition, easily form burner hearth desirable, that rule are positive in the electrolytic cell of this kind side lining, convenient operation, and be that suitable condition is created in continuous blanking and gas cleaning.
