Description
Technical Field
The invention relates to the technical field of electrolytic aluminum liquid production, in particular to an electrolytic aluminum preparation process.
Background
An important index of the electrolytic aluminum liquid production is the quality of the aluminum liquid, and the aluminum liquid with higher purity can ensure that the formed product has good physical and chemical properties.
In the production of aluminium slabs, there are sometimes gases entering the aluminium melt for various reasons during the melting of the aluminium ingot. When the aluminum liquid with gas passes through the casting nozzle in front of the upper and lower rollers of the casting roller, bubbles are formed at the front edge of the casting nozzle, and are brought below the surface layer at the moment of aluminum liquid forming, so that an air passage is formed on the shallow surface layer of the slab, and the expression form of the air passage is that the slab after casting and rolling has an unobvious white strip. Because the air channels are below the surface of the slab, they are always entrained in the slab during further processing. If the plate blank is used for producing an aluminum plate or an aluminum foil, holes can be formed on a final product through rolling at the air passage; if the above-mentioned blank is used to produce a punched product, the air channels are broken and the product is discarded, so that the product quality must be picked up from the blank.
At present, when a first-line worker for casting aluminum finds that an aluminum plate blank after casting and rolling has an unobvious white strip and then is confirmed to be an air passage through low corrosion, a general treatment method is to immediately stop the machine to block aluminum liquid flowing to a casting nozzle, then the casting nozzle in use is detached and replaced with a new casting nozzle, and then the machine is restarted to re-erect the plate for production, so that the problem can be solved within 3 hours by one-time shutdown, normal production is delayed, at least 2-3 tons of plate blanks cannot be used when the plate is re-erected and re-melted after being returned to the furnace, and the loss of one-time shutdown is about 0.3 ten thousand yuan/ton. According to statistics, the rejection rate of the aluminum plate blank caused by the air passage problem is about 1%, calculated by the yield of 25000 tons of annual output, except that the planing worker can only find the air passage after the delay and can not make up the factor, the annual cost for solving the problem is about 50 ten thousand yuan, so that the production cost is greatly improved.
