Abstract
The invention relates to a fusing agent, particularly a fusing agent used at the fusion welding stage in the process of the electrolytic aluminium anodic steel claws repairing. which aims at providing a fusing agent capable of producing no air holes on the welding portion, increasing melting speed and reducing energy consumption. The following technical scheme is adopted: the fusing agent applied to electrolytic aluminium anodic steel claws repairing is composed of A12O3, CaF2and CaO. Compared with the prior technology, the fusing agent for electrolytic aluminium anodic steel claws repairing has the advantages in that: (1), the fusing agent floats in a metal pool and isolates outside air so as to avoid producing defects such as shrinkages, air holes and the like (2), the fusing point is decreased, fusing speed is increased and the energy consumption is reduced.
Description
Technical field
The present invention relates to a kind of fusing assistant, employed fusing assistant of melting welding stage in especially a kind of electrolytic aluminium anode steel pawl repair process.
Background technology
At present, domestic each electrolysis aluminum production enterprises all adopts artificial electric welding reparation to the method for steel pawl reparation, removes from the position of steel pawl leg seriously corroded, welds up through electric welding with new rod iron.The centre of this kind restorative procedure between steel pawl leg and rod iron exists not have welding and is surrounded the cavity that seals by weld seam; Air in the cavity can sharply expand at adstante febre; Generation has makes steel pawl leg and rod iron throw off the huge tension force of trend; Possibly cause the artificial steel pawl leg of repairing in the commissure " disconnected leg ", energy consumption is also very high in addition.
Summary of the invention
The purpose of this invention is to provide a kind of welding portion that guarantees and do not produce pore and the fusing assistant that improves burn-off rate, cuts down the consumption of energy.
For realizing above-mentioned purpose, the present invention adopts following technical scheme: a kind of fusing assistant that is applied in the reparation of electrolytic aluminium anode steel pawl, said fusing assistant is mainly by Al
2O
3, CaF
2, CaO forms.Wherein each component concentration is (percentage meter by weight): Al
2O
315%-25%, CaF
255%-70%, CaO 5%-20%.
Said fusing assistant is a crucial auxiliary material of melting welding stage in the electrolytic aluminium anode steel pawl repair process, can use repeatedly, can use after general pulverizing mixes.In fusion process; Fusing assistant can not only reduce fusing point; Float over simultaneously make on the metal pool metal pool all the time with isolate from outer air; Played preventing burning and the effect of dispelling the heat on the one hand, also played the effect of high temperature rising head on the other hand, made in the top reparation that " growth " comes out by the continuous solidification and crystallization of liquid metal of remaining steel pawl leg and partly avoided generation of defects such as shrinkage cavity, pore to atmosphere; This just makes the reparation part intensity of coming out because of melting welding " growth " identical with steel pawl body portion at least, even a little more than cast steel steel pawl matrix strength.
The present invention compared with prior art has following advantage:
1, because melting welding stage fusing assistant floats on and completely cut off outside air on the metal pool, generation of defects such as shrinkage cavity, pore have been avoided.
2, reduce fusing point, improved burn-off rate, also reduced energy consumption simultaneously.
