Abstract
The composition of exothermic welding flux for welding method contains (A). copper oxide with oxidation rate of 20-80% and 40-100 meshes, 100 portions; (B) aluminium powder with 100-200 meshes 10-50 portions; (C) silicon dioxide 1-10 portions and magnesium oxide or/and calcium fluoride 4-22 portions. Said invention utilizes the control of copper oxide grain size and oxidation rate to regulate exothermic reaction of welding flux and temp. of molten metal reduced after the exothermic reaction, and can use 2500-3400 deg.c to attain the goal of implementing welding and ensuring welding quality.
Description
The present invention relates to a kind of exothermic welding flux of weld metal.
Usually, metal solder all needs external power supply or fuel gas, and like this, operation is very inconvenient in the open air, in the high mountain, big seagoing vessel.Therefore, be in this environment, now modes such as bolt, periphery pressurization, crimping that adopt connect more.But this connected mode joint is aging fast, and special earth mat for cable laying, power plant of transformer station lays, the ground connection of skyscraper is accidents caused easily.A kind of exothermic welding flux was also once arranged before the present invention, as publication number be CN1069215A, open day be February 24 in 1993 day, be called the Chinese patent application of " a kind of be used for solder flux and the detonator that copper connects the thermit welding that connects line ", it utilizes exothermic reaction to weld as thermal source, overcome above-mentioned shortcoming, but this solder flux is in order to cool off the control exothermic reaction, in prescription, added pure copper powder, so just influenced the temperature of the molten metal that exothermic reaction produced, make the metal melting welding be affected, the weldment quality can not get guaranteeing.
The object of the present invention is to provide and a kind ofly can give full play to exothermic reaction, thereby guarantee the exothermic welding flux of weldment quality.
For achieving the above object, the present invention is by the following technical solutions: it basic composition is:
A) oxygenation efficiency 20%-80%, 40 orders-100 purpose cupric oxide are 100 parts,
B) 100 orders-200 purpose aluminium powder is 10 parts-50 parts,
C) silica 1 part-10 part,
D) magnesia is or/and 4 parts-22 parts in calcirm-fluoride,
Above umber by weight.
Above-mentioned magnesia and calcirm-fluoride add fashionable simultaneously, and preferred version is 2 parts-11 parts in magnesia, 2 parts-11 parts in calcirm-fluoride.
The present invention utilizes the proportioning of the control granularity of cupric oxide and oxygenation efficiency and component to adjust the molten metal temperature that is reduced into after the exothermic reaction of solder flux and the reaction, give full play to exothermic reaction, utilize the present invention to reach the thawing of weldment termination and finish fusion weld with the high temperature of 2500-3400 degree, making the weldment joint is molecular structure, guarantees welding quality.Utilize the present invention to weld, solder joint can not produce corrosion and lax; Owing to be to merge joint, there is not contact surface not have residual stress between weldment; The present invention is applied to cable conductor, can not be subjected to the damage of high surge current, and under the impact of big electric current in short-term, conductor melts prior to joint, has bigger area of dissipation simultaneously, and the live ability equates with conductor, is a kind ofly need not keep in repair nonvolatil plumb joint.The present invention also can make welding jig light, need not the professional is any can operate per capita, be particularly suitable for special occasions such as field and use, be a kind of economy, convenience, reliable in quality, widely used exothermic welding flux.
