Abstract
The invention belongs to a kind of new source of the flux material in the welding technology field---the twice laid invention of iron-tion slag, and the manufacture method of this kind solder flux.It has solved the problem of producing a large amount of electric power of solder flux consumption with " smelting process ".Turn waste into wealth, turn bane into boon.Its manufacture method can be the slag that directly will melt, form when melting molten iron, molten steel through Mechanical Crushing, screening, packing, become finished product.Can with the slag base-material also, allocate auxiliary materials mixing such as a certain proportion of ore, rich slag, alloy, fragmentation by the requirement of flux constituent into, screen, pack or mix melting together in the cupola furnace, become finished product through slag tap winding-up or Mechanical Crushing, screening, packing.
Description
The invention belongs to the twice laid invention of a kind of new source-iron-tion slag of the flux material in the welding technology field, and the manufacture method of this kind solder flux.Known to the applicant, be used for large pieces such as boats and ships, bridge solder flux automatic or semiautomatic welding submerged arc aspect at present and produce with " smelting process ".This method is the lumpiness that will be crushed to by raw material such as the ore of flux constituent requirement, lime stone, fluorites less than 50mm, then in electric arc furnaces with being electrically heated to about 1600 ℃, melting forms, and product energy consumption is high, and can't add the strong alloying constituent of deoxidation power.
The production of ironcasting, steel-casting is at present all melted molten iron usually in furnace cupola, three joint stoves, cupola furnace, line frequency furnace, electric arc furnaces.Owing to melt the ash content that a great deal of is arranged in used fuel one coke of molten iron, iron and steel cold burden surface is with foreign material such as silt, oxides.For making iron process is carried out smoothly, must add slag making such as some sludging flux-lime stones, fluorite, alloy.The quantity of slag of Xing Chenging is generally the 3-8% of iron amount at last.These bits are so far basically all with waste disposal.
The similar iron-tion slag of solder flux that purpose of the present invention utilizes these chemical compositions and " smelting process " to produce exactly is directly as solder flux or suitably be treated as the solder flux of particular requirement.
The present invention is achieved in that
Slag fragmentation → screening → packing → the finished product that forms during 1, directly with melting molten iron, molten steel.
2, the slag that generates with fusing, melting molten iron, molten steel is a base-material, allocates auxiliary material such as the ore of proper proportion, rich slag, alloy into by the flux constituent requirement, mixing → fragmentation → screening → packing → finished product.
3, adding becomes solder flux by a certain proportion of ore of flux constituent requirement, rich slag, alloy melting when fusing molten iron, molten steel, slags tap through winding-up or Mechanical Crushing → screening → packing → finished product.
Below for several embodiment.
Embodiment one: get cupola furnace acid slag, main frequency furnace acidification scum each 50%, Mechanical Crushing, screening.Get 10～40 purpose particles through 250 ℃ of oven dry 0.5-1 hour, metering packing.Product is low manganese high-silicon low-fluorine solder flux.Composition is SiO
240-46%, CaF
27-11%, CaO8-14%, MgO10-14%, Al
2O
310-17%, MnO5-10%, FeO≤1.5%, S≤0.05%, P≤0.05%.
Product purpose: submerged arc welding mild steel, normal low carbon steel.
Adapted welding wire: H08MnA, H10Mn2
Be suitable for power supply: AC and DC is dual-purpose.
Embodiment two:
Get and be crushed to 10-40 purpose cupola furnace acid slag 80-85 gram, join the fluorite 15-20 gram that is crushed to same granularity, mix,, be fluorine solder flux in the low high silicon of manganese through 250-300 ℃ of oven dry 0.5-1 hour.
Product purpose: roll overlaying, stainless steel welding
Adapted welding wire: stainless steel welding stick
Be suitable for power supply: dc source
Embodiment three:
When preparing burden in the cupola furnace, allocate the manganese slag (or manganese ore) of the 1.5-1.8% of iron amount into, through the melting slag making, after the discharging, Mechanical Crushing is with the choosing of 10-40 mesh sieve, packing.The low fluorine type solder flux of the low silicon of manganese during product is.
Advantage of the present invention is: fully developed these change iron slags and made-the electric welding solder flux, had very high economic benefit. Turn waste into wealth. Simultaneously a large amount of electricity saving and energy savings. Utilize iron-tion slag to make solder flux and can require to adjust its composition according to the solder flux of the different trades mark, the solder flux that smelting process is produced then can't add the strong alloying constituent of deoxidation power.
