Abstract
The flux consists of industrial sylvite 25-35 portions, potassium fluoroborate 25-35 portions, potassium or sodium fluoride 15-20 portions, Cryolite 10-15 portions and ammonium fluorosilicate 10-15 portions. It has the advantages of fast melting, easily exhausted molten weld bath for exhaust and oxide, good flowability, low impurity, capability to result in smooth welded or cut surface, high antioxidatnt property and long service life.
Description
The present invention relates to a kind of multifunctional metal welding and cutting flux, be applicable to fluxing of electrogas welding, the various metal weldings of carbon welding resistance.
The various non-ferrous metals of traditional welding must use welding agent, welding of aluminum and aluminium alloy use the aluminium powder welding agent, and copper or copper alloy use borax type brazing powder welding agent, and tin or ashbury metal use the rosin tinol, and ferrous metal is because kind is too many, general employing electric welding, gas welding and gas cutting, different welding rods is adopted in electric welding, the oxygen that gas welding or gas cutting use, acetylene gas mixing fire is sauted combustion and is cut, this traditional welding method, the fusing of metal welding face is slow, and power consumption is big, molten bath gas and oxide can not arranged, the mobile property of molten metal is poor, and impurity is many, and it is bad to cause solder side to coincide, fineness is poor, oxidation resistance is low, and welding is of poor quality, and service life is short.
The flux that uses when purpose of the present invention provides a kind of suitable electrogas welding, carbon welding resistance to various metal welding for the shortcoming that overcomes above-mentioned prior art with deficiency just, thus the welding quality improved, improve service life.
The objective of the invention is to realize by following technical proposal:
Multifunctional metal welding and cutting flux is characterized in that it is the pulvis of making through pulverizing by with following materials of weight proportions:
Industry sylvite 25-35 part potassium fluoborate 25-35 part potassium fluoride or sodium fluoride 15-20 part
Cryolite 10-15 part ammonium fluosilicate 10-15 part.
Flux of the present invention, primary industry sylvite wherein, promptly industrial salt mainly is potassium chloride, sodium chloride compound, also claims sal amarum, and it can mix with fluoride, and the various metals of welding are fluxed, and China's Qinghai salt mine abounds with, and the potassium fluoborate molecular formula is KBF
4, can with the alkali carbonate fusion, be the flux of hot weld and copper, metals such as welding and fusion gold, silver, stainless steel, chemical plant such as Shanghai, Changshu, Beijing produce, potassium fluoride or sodium fluoride, it and fluoride, chloride are compound, can be as the flux of all metal weldings; Aluminium sodium fluoride, be metal fusing agent, chemical plant, Changshu produces, and has non-oxidizability; The ammonium fluosilicate molecular formula is (NH
4)
2SiF
6, be the metal solder flux, Shanghai chemical reagent work produces; Select the flux of above-mentioned raw materials preparation for use, can make the various metals of welding and fuse the universal of various metals and flux.
Owing to take technique scheme, make the technology of the present invention compared with the prior art have following advantage and effect:
A) the various metals of welding are fluxed soon, and metal flow is good, and molten bath exhaust and oxidation impurities are strong, and the welding face is anti-oxidant, and is highly polished, and the welding quality is good, long service life;
B) raw material sources are extensive, and production method is simple, and purposes is wide, and are energy-conservation;
C) using method is easy, as long as flux is added water furnishing pasty state, spreads upon on the welding line, or an amount of on the welding rod, can carry out welding, can add a little to the fusing of gold, silver and mix heat fused thoroughly and go into mould, and general use now tempers and promptly uses.
