Abstract
The invention relates to a material for an aluminum electrolysis crust-breaking hammer, which is characterized by comprising the following components in percentage by weight: 0.5%-3.0% of carbon, 3.5%-10.0% of manganese, 0.5%-1.0% of silicon, less than 0.05% of phosphorus, less than 0.05% of sulphur, 5.0%-20.0% of chromium, less than 0.05% of Ni and the balance of ferrum. The material for the aluminum electrolysis crust-breaking hammer is an iron alloy material and is prepared by using a lost foam casting or sand casting process. In the invention, The manganese content in the material for the crust-breaking hammer is increased and the chromium content is optimized, thereby the material effectively improves the strength and wear resistance of the aluminum electrolysis crust-breaking hammer, prolongs the service life of the hammer, extends the replacement period, reduces the production cost and effectively relieves the labor intensity.
Description
Technical field
The present invention relates to a kind of crust beating hammer for aluminium electrolysis material.
Background technology
Aluminium cell is the main equipment of aluminium metallurgy, since spontaneous clear sodium aluminum fluoride-alumina molten salt electrolysis method, to have continued more than 100 year.The production technology of electrolysis of aluminum has also had great progress, by point feeding large-scale pre-baked aluminum electrolysis cell in the middle of the computer control-automatization till now of initial small-scale test groove.Middle point feeding is controlled the strike tup by the computer control magnetic valve exactly, thereby break up the hard crust of bath surface, be commonly called as " crust breaking ", form hole, this hole is commonly called as " pinkeye ", " pinkeye " must keep it unblocked as the passage of aluminum oxide feeding point and anodic gas discharge constantly.The maintenance that " pinkeye " is unimpeded just needs control crust breaking system to drive the crust breaking action of crust-breaking chips execution cycle property.Therefore, the crust breaking action also makes crust-breaking chips be in the continuous state of wear, in case the crust-breaking chips loss is too much, just needs to change.Therefore, improve the wear resisting property of crust-breaking chips, will help and reduce production costs the workload of overhauling in the reduction production process.
At present crust-breaking chips adopted material the time forge Q235, casting ZG235-270 iron and steel or other plain carbon stool, the steel hardness of these materials is low, fusing point is low, abrasion resistance properties is poor, so the life-span is shorter, just needs to change once in every 3-4 month.Trade mark ZG30Cr26Ni5 or ZG30Cr20Ni10 steel that patent 200610050934.1 has designed to meet among the GB/T8492-1987 are the crust-breaking chips of material; Patent 200910117260.6 inventions have designed with rare-earth and high chromium steel (C 1.5-2.5%, Si 0.5-1.5%, Mn 0.2-1.5%, Cr 25.0-35.0%, P and S＜0.05%, mishmetal 0.075-0.1%) be the crust-breaking chips of material, the common feature of these two kinds of materials all is to have improved the Cr content in the tup, has improved the hardness and the fusing point of iron and steel.But the raising of fret wear performance not only needs a very high hardness, also needs to have higher strength and toughness.
Summary of the invention
The objective of the invention is deficiency, provide a kind of wear resistance strong, the crust beating hammer for aluminium electrolysis material that life cycle is long at prior art.
The objective of the invention is to be achieved through the following technical solutions.
A kind of crust beating hammer for aluminium electrolysis material is characterized in that this material weight per-cent composition comprises: carbon 0.5%-3.0%, manganese 3.5%-10.0%, silicon 0.5%-1.0%, phosphorus are less than 0.05%, and sulphur is less than 0.05%, chromium 5.0%-20.0%, Ni are less than 0.05%, and all the other are iron.
A kind of crust beating hammer for aluminium electrolysis material of the present invention is a kind of ferroalloy materials, its preparation process (please discloses a kind of,) material of the present invention is by increasing the manganese content in the crust-breaking chips material, optimized chromium content, the intensity and the wear resistance of crust beating hammer for aluminium electrolysis have effectively been improved, improve the work-ing life of tup, prolonged the replacement cycle, reduced production cost and workload.
