The basic components of the formula of heat releasing welding powder are mixed copper oxide powder, aluminum powder and other auxiliary materials. One kind of the mixed copper oxide powder is copper oxide sheets with the oxidation rate being over 80%, the oxygen content being 13.5% and the particle size ranging from 30 meshes to 100 meshes, and the other kind of the mixed copper oxide powder is the mixed copper oxide powder with the oxidation rate being 50% to 75% and the particle size ranging from 30 meshes to 100 meshes obtained by mixing copper oxide wires with the oxidation rate being 40% to 60%. The aluminum powder is flaky atomizing aluminum powder with the particle size ranging from 40 meshes to 60 meshes. The other auxiliary materials are mixed powder of iron powder, fluorite powder, silicon iron powder and silicon dioxide powder, and the particle size ranges from 100 meshes to 200 meshes. The heat releasing welding powder formula does not contain phosphorus, sulfur, lead, tin, magnesium and other poisonous metal. The heat releasing welding powder formula adjusts the reaction speed and the reaction temperature by adjusting the oxidation rate and the particle size of the mixed copper oxide powder, and is stable in welding, free of splashing and free of welding seam defect.
Description
Technical field
The invention belongs to the welding powder technical field of welding material, be specifically related to a kind of heat release welding powder formula.
Background technology
Conventionally metal solder all needs external power supply or fuel gas to carry out electric welding or welding operation is carried out in gas welding, but it is all very very inconvenient to carry operation for field, high-altitude etc.Equipment is simple, small investment because possessing for heat release welding technology, and weld job is fast, does not need large power supply, simple to operate and be applicable to the welding under complex environment.
Heat release welding is the chemical reaction that utilizes aluminium and cupric oxide, in resistant to elevated temperatures graphite jig, utilize high temperature to make active stronger aluminium by copper oxide reduction, by producing excessive heat copper liquid motlten metal conductor in mould, utilize the mold cavity of definite shape, size to complete the modern welding procedure of fusion splice, conventionally also claim heat release welding, heat release melting welding, chamotte welding.Heat release weldering welding quality depends on the chemical composition of hot melt scolder and corresponding detonator.
CN200910092115.1 discloses a kind of copper-clad steel/copper grounding grid heat release welding flux with high safety, its technical scheme provides a kind of exothermic welding flux, exothermic welding flux weldering cupric oxide weight percentages of components is 45～65%, in order to improve mobility, recruitment metallic tin powder weight is 1%～3%, wherein contains expensive metallic tin the cost of exothermic agent is increased.
Mono-kind of CN1069215A connects the solder flux of thermit welding and the Chinese patent of detonator of wire for copper, it utilizes exothermic reaction to weld as thermal source, this solder flux is for the cooling pure copper powder that added in formula, such temperature that can affect molten metal, metal solder is affected, and weldment quality is unstable.
Summary of the invention
The object of the present invention is to provide one can give full play to exothermic reaction, and guarantee welding quality, and course of reaction is steady, without splash, and in formula, the poisonous metal such as not phosphorous, sulphur, lead, tin, magnesium, has not only reduced production cost but also can ensure operator's safety and the quality of pad.
The present invention adopts following technical scheme to be:
A heat release welding powder formula, according to components by weight percent meter, comprises following component:
80～85 parts of mixed oxidization copper powders, 10～15 parts of aluminium powders, 3～5 parts of other auxiliary materials.
Described mixed oxidization copper powder refers to mixing according to certain ratio of two kinds of cupric oxide, one be oxygenation efficiency be more than 80%, containing oxygen be 13.5%, 30～100 objects are oxidized copper sheets, another kind is that oxygenation efficiency is 40%～60% cupric oxide rice; Mixing by different proportion can obtain oxygenation efficiency 50～75%, and granularity is 30～100 object mixed oxidization copper powders.
Described aluminium powder is sheet atomizing aluminium powder, and granularity is 40～60 orders;
Other described auxiliary materials refer to iron powder, Fluorspar Powder, ferrosilicon powder, SiO 2 powder, and its granularity is 100～200 orders.1～1.5 part of iron powder, 0.5～1.5 part, fluorite powder, 0.3～0.5 part of ferrosilicon powder, 0.5～1 part of silica (percentage is remembered with weight);
The effect of various auxiliary materials in welding powder formula:
iron powderbe the auxiliary element of welding powder, in formula, contain a small amount of iron powder, all fusings in exothermic process, in fusion process, absorb energy, the effect of iron powder, compared with metallic copper, recepts the caloric high, and temperature after fusing is also higher, can effectively improve the temperature of copper liquid; In welding powder, contain a small amount of iron powder simultaneously and contribute to increase mobility, improve the intensity of pad, and improve hardness.But need the strict content of controlling iron powder.
fluorspar Powder and ferrosilicon powderbe extraordinary slag former and deoxidier, play the slag making of fluxing, eliminate pore, improve the effect of the surface quality of heat release pad.
silicamainly play the effect of the metallographic structure that improves heat release pad, ferrosilicon powder also has same effect, but ferrosilicon powder is mainly deoxidier.
The poisonous metals such as heat release welding powder formula provided by the invention is not phosphorous, sulphur, lead, tin, magnesium; Heat release welding powder provided by the invention is that oxidizability and the granularity by regulating mixed oxidization copper powder come reaction speed and reaction temperature, makes welding steadily, without splash, and weld seam zero defect, instead of by adding pure copper powder to regulate reaction temperature.
