10-60 Mesh Mild Steel Sintered Flux three functions
10-60 Mesh Mild Steel Sintered Flux is a granular welding material. In the welding it can melt to form slag and gas, the protection of the molten pool and metallurgical effect.
10-60 Mesh Mild Steel Sintered Flux is divided into acidic, neutral and alkaline 3, according to the manufacturing method is divided into smelting 10-60 Mesh Mild Steel Sintered Flux and non-smelting 10-60 Mesh Mild Steel Sintered Flux. Melting 10-60 Mesh Mild Steel Sintered Flux is a variety of ore by the arc furnace smelting after smashing. Among them, the acidic smelting 10-60 Mesh Mild Steel Sintered Flux application more, it is accompanied by appropriate wire, widely used in carbon steel and low alloy structural steel welding. Neutral and alkaline smelting 10-60 Mesh Mild Steel Sintered Flux is used for high strength steel welding. Non-smelting 10-60 Mesh Mild Steel Sintered Flux is simple to manufacture, good labor hygiene conditions, easy to control the quality, and can join the various alloying elements to improve the weld metal structure and performance, and thus get a wider range of applications. Non-smelting 10-60 Mesh Mild Steel Sintered Flux drying temperature below 400 ℃, known as bonding 10-60 Mesh Mild Steel Sintered Flux; drying temperature of 400 ~ 1000 ℃, called sintering 10-60 Mesh Mild Steel Sintered Flux, the latter strength is good, high yield, more applications.
10-60 Mesh Mild Steel Sintered Flux function can be divided into three parts:
1, remove the welding surface of the oxide, reduce the solder melting point and surface tension, as soon as possible to reach the brazing temperature.
2, to protect the weld metal in the liquid from the surrounding atmosphere is not affected by harmful gases.
3, so that liquid solder with a suitable flow rate to fill the brazing seam.
The melting point of the flux should be lower than the melting point of the solder 10-30 ℃, in particular, the flux can also be higher than the melting point of solder. If the melting point of the flux is too low, the flux is lost before the solder is melted, and the flux is lost when the solder is melted due to evaporation or the effect of the base metal. The choice of flux is usually dependent on the nature of the oxide film. Alkaline oxide films such as Fe, Ni, Cu and the like often use acidic boron-containing boron-enriched (B2O3) fluxes, and the acidic oxide film, for example, to the cast iron containing high SiO2 oxide film commonly contains alkaline Na2CO3 Of the flux to produce fusible Na2SiO3 into the slag. Some of the fluoride gas is also commonly used as flux, they react evenly, leaving no residue after welding. BF3 is often mixed with N2 for brazing stainless steel at high temperatures. The brazing flux used at 450 ° C is a softener. Softener is divided into two kinds, one is water-soluble hydrochloric acid and phosphate is usually a single or Sox salt aqueous solution, high activity, corrosive, after welding need cleaning. The other is water-insoluble organic flux, usually rosin or artificial resin-based, adding organic acids, organic amines or their HCL or HBr salt, to improve the membrane capacity and activity.
 At present, China's smelting 10-60 Mesh Mild Steel Sintered Flux is about one-fifth of the welding for vertical reinforcement. Manganese ore resources are relatively lack of suitable for the production of smelting 10-60 Mesh Mild Steel Sintered Flux of high grade, low phosphorus content, low iron content of the manganese ore even less. In line with the production of 10-60 Mesh Mild Steel Sintered Flux manganese ore goods increasingly tense.
High manganese slag 10-60 Mesh Mild Steel Sintered Flux, developed to promote the manganese, low manganese 10-60 Mesh Mild Steel Sintered Flux has become an urgent need for urgent tasks. But also with the content of manganese wire production and expansion of the supply of manganese and low manganese slag 10-60 Mesh Mild Steel Sintered Flux should have a broad market, commodity 10-60 Mesh Mild Steel Sintered Flux technical performance description , In the industry on the usual practice is smelting 10-60 Mesh Mild Steel Sintered Flux gives its chemical composition and with a welding wire of the deposited metal mechanical properties, sintering 10-60 Mesh Mild Steel Sintered Flux only gives its Slag composition and with a welding wire welding metal mechanical trunk energy.
10-60 Mesh Mild Steel Sintered Flux chemical composition by batch of chemical composition analysis, in addition to analytical methods and equipment on the difficulty of the results and the user's requirements between the use is still far apart. 10-60 Mesh Mild Steel Sintered Flux Manufacturer provides information in the product description with the following technical contents. In the welding of low-alloy high-strength steel with 10-60 Mesh Mild Steel Sintered Flux in the national standard, 10-60 Mesh Mild Steel Sintered Flux alkalinity is marked 10-60 Mesh Mild Steel Sintered Flux metallurgical performance, process performance, Current types and weldable steel grades such as the first of the technical indicators, the most suitable for matching the use of several welding wire metal mechanical function, the user in the selection of a larger space. Special recommendations 10-60 Mesh Mild Steel Sintered Flux manufacturers to provide 10-60 Mesh Mild Steel Sintered Flux metallurgical behavior map.
