Description
Technical field
The invention belongs to the crust breaker of aluminum smelting technology technical field, what be specifically related to is a kind of aluminium cell crust-breaking chips of aluminum electrolysis technology.
Background technology
At present; Point type crust breaking cutting mode in the middle of the known prebaked-anode type cell of aluminum electrolysis industry all adopts; Every the electrolyzer that is used for aluminum electrolysis technology; Generally be provided with three to six crust-breaking chipss and replace the crust breaking blanking, for example the magnitude of current is the middle alternately crust breaking cutting mode in four some positions of electrolyzer employing of 240 kilo-amperes, and the magnitude of current is to replace the crust breaking cutting mode in the middle of the electrolyzer of 300 kilo-amperes adopts five some positions.
It is 450 millimeters that existing aluminium cell crust-breaking chips adopts length, and diameter is that 95 millimeters 45# round steel is processed.Aluminium electrolyte temperature in the electrolyzer is in 950 deg.c; A plurality of positions are through program control alternately crust breaking blanking; Can cause crust-breaking chips worn and torn by the aluminium electrolyte temperatures involved; Receive the crust-breaking chips of temperatures involved wearing and tearing will become cone in three months about using greatly, its shape is the same as the pencil stub of cutting with pencil-knife.For not influencing crust breaking blanking efficient, must change the crust-breaking chips after wearing and tearing.For example the smelting shop of one 300 kilo-ampere electrolytic aluminum is provided with 156 electrolyzers; Every electrolyzer is provided with 5 crust-breaking chipss, about 60 kilograms of every tup weight, and disposable installation crust-breaking chips is: 5 * 156=780 root; Needs were changed four tups in 1 year; Need 3120 tups every year altogether, adds up to about 187.2 tons of tonnage
Changed No. four crust-breaking chipss, and caused the steel consumption amount that is used for crust-breaking chips big in 1 year.The gross weight of the crust-breaking chips in one 300 kilo-ampere electrolytic aluminum smelting workshop is about 187.2 tons; The tup that dismounting is worn also need be installed new tup simultaneously again; The steel gross weight of this dismounting and installation crust-breaking chips process is ton surplus in the of 360 approximately; Cause serviceman's labour intensity big, the batch replacement crust-breaking chips also influences ordinary production.Iron filings after crust-breaking chips is worn mix in the electrolysis aluminium ingot, make the electrolysis aluminium ingot increase the content of iron and steel, and are also influential relatively to the quality of aluminium ingot.
Summary of the invention
The object of the invention in order to strengthen the wearability of crust-breaking chips, improves the work-ing life of crust-breaking chips exactly, has designed a kind of aluminium cell crust-breaking chips.
The present invention realizes through following technical scheme: a kind of aluminium cell crust-breaking chips; Form by steel pipe, connection handle and tup; Wherein the steel pipe end walls is provided with the plug welding hole, and steel pipe one end inserts the connection handle that has hinge hole, and the steel pipe the other end is installed tup; Implement the filling weldering connects in the plug welding hole; Connect along implementing fillet welding at the steel pipe port, it is characterized in that the end that tup is installed at steel pipe inserts the tup core, tup core external diameter is set with high temperature resistant steel pipe; Rivet with rivet pin and tup core after the tup core bores a plurality of riveted holes at the high temperaturesteel tube wall, the high temperaturesteel length of tube that is sleeved on the tup core constitutes compound aluminium cell crust-breaking chips more than or equal to tup core termination.The high temperature resistant steel pipe of said tup core external diameter suit is a stainless steel tube; The high temperature resistant steel pipe of tup core external diameter suit also can be the tubing of other TS material.The high temperaturesteel infratubal port that is sleeved on tup core external diameter can be provided with capping.
Aluminium cell crust-breaking chips of the present invention is installed in the electrolysis tank, in crust breaking blanking process, receives the influence of 950 deg.c electrolytic aluminum melt temperatures less, and the crust-breaking chips degree of wear is low, can prolong the work-ing life of crust-breaking chips relatively.Aluminium cell crust-breaking chips of the present invention; At least in 12 months, can not change because of the crust-breaking chips wearing and tearing; Compare with existing crust-breaking chips, significantly reduced the steel consumption that causes because of the crust-breaking chips wearing and tearing, also alleviated the serviceman simultaneously because of changing the labour intensity of crust-breaking chips; Have significant result of use, accomplished the object of the invention.
