Abstract
The invention relates to a side block structure for a kiln lining and particularly relates to a side block composite filling material structure which is high temperature resistant, corrosion resistant, wearing resistant, anti-oxidant, high in strength, long in service life and low in cost for an aluminum electrolysis cell lining and a processing method of the side block composite filling material structure. According to the side block composite filling material structure, one side, back to a furnace chamber, of the side block is integrated with a filling material. The side block composite filling material structure disclosed by the invention has the advantages that the side block structure is changed by adopting the side block composite filling material structure, structural strength and corrosion resistance of the side block are greatly improved by combining with a high-strength anti-seepage or thermal-insulation material, thermal insulation is strengthened and stabilized, and economic cost is lowered; the side block composite filling material structure is simple in structure and easy to machine and manufacture on site.
Description
Technical field
The present invention relates to a kind of stove liner side block structure, relate in particular to high temperature resistant, corrosion-resistant, wear-resistant, anti-oxidant, high strength for a kind of internal lining of aluminium electrolytic bath, long lifetime, side block composite filling material structure and machining method cheaply.
Background technology
Along with the progress of aluminum electrolysis technology, aluminium cell is gradually to low voltage, less energy-consumption future development, so insulation becomes the important step that can electrolyzer reach energy conservation object.And in lining structure of aluminium electrolytic bath, side block is the key part of protection high temperature, deep-etching liquation, because the heat dissipation capacity in bath of cell district is larger, so side block insulation is the most important thing of lining-design.
Conventional side block material has two kinds at present, i.e. common charcoal element and silicon nitride combined silicon carbide.In order to strengthen sidepiece insulation, generally take two kinds of methods, the one, on side block side, be close to certain thickness warming plate; Or recessing in side block, inlays warming plate wherein, with this, strengthens the insulated capacity of side block.In aluminium cell operational process, infiltration due to high temperature, deep-etching liquation, the crimp that inner lining structure thermal expansion stress causes makes every physical and chemical index of warming plate occur to a certain degree to change, directly affect structural strength and the heat-insulating property of warming plate, even caused electrolyzer operation conditions that deterioration to a certain degree occurs.
Summary of the invention
In order to solve the problems of the technologies described above, the invention provides a kind of side block composite filling material structure and machining method, object is to improve the structural strength of side block, stablizes heat-insulating property, strengthen anticorrosive, wear-resistant and resistance of oxidation, reduce Financial cost and simplify the course of processing.
For reaching above-mentioned purpose side block composite filling material of the present invention structure, the side block back of the body forms integral body towards a side and the packing material of burner hearth.
The side block back of the body is towards a side recessing of burner hearth, and depth of groove is less than side block thickness, and packing material is located in groove.
Groove quantity is 1～20.
The side block back of the body is towards a side recessing of burner hearth, and packing material is prefabricated into convex shape sheet material, is embedded in the groove of side block.
Packing material is prefabricated into long strip shape sheet material, with side block stickup shaping.
Between packing material and side block contact surface, be provided with kraft paper.
Packing material is antiseepage or lagging material, that packing material has is high temperature resistant, corrosion-resistant, resistance to oxidation and thermal expansivity little.
Packing material is antiseepage mould material, ramming mass, refractory mortar, refractory brick or insulating brick.
Packing material, by ramming compacting, is filled in the groove of side block.
Side block material is silicon nitride combined silicon carbide or common charcoal element piece.
Advantageous effect of the present invention:
Adopt the present invention to change side block structure, by antiseepage or the lagging material of combined high-strength, greatly promoted structural strength and the resistance to corrosion of side block, strengthen and stablized heat-insulating property, reduced Financial cost, this is simple in structure, is easy to in-situ processing and makes.
