Properties of the properties about Ferro tungsten

The properties about Ferro tungsten admixture ancestors is (tungsten agreeable of: 70% -80%), consisting of tungsten and adamant alloys, animate alloys acclimated additives. Commonly acclimated tungsten tungsten absolute 70% adamant and 80% of the two. Tungsten adamant admixture furnace, as top melting point, the aqueous can not be released, so the use of accession adjustment or crop the assembly of iron. 1930s afore the accepted with a baby (100 to 500 kVA) single-phase electric arc boiler for admixture agglomeration, again about-face to the three-phase electric furnace, and developed to crop adamant law. China Jiangxi, Hunan, Guangdong, one with a ample amount of tungsten ore affluence of the apple 60 ~ 70%. From 1936 to 1938 in Ji'an, Jiangxi Tungsten ironworks preparation, accession accession adjustment application kVA three-phase electric boiler 2000, has been abundantly completed, due to the appulse of the War of Attrition pause. 1955 Jilin Ferroalloy Plant began to crop adamant adjustment application 3500 KVA electric boiler assembly of tungsten iron. Tungsten to block delivery, the block ambit of 10 ~ 130mm, beneath than 10 × 10mm bits should not beat 5% of the absolute weight of the batch, acceptance alone lumpiness in one administration the best admeasurement is 150mm. Tungsten adamant apparent should be smooth, no cogent array and apparent non-metallic inclusions and rust. Tungsten and tungsten adamant is an admixture of iron. It is acclimated in animate authoritative and casting abettor is added as tungsten, tungsten is the assembly of appropriate animate is one of the a lot of important alloying element. Tungsten can abate the amount of addendum of the animate is not the aforementioned time, advance the backbone of animate and the crop point limit, but aswell advance the acerbity and abrasion resistance. Of accurate accent is tungsten temperature automated backdrop of the animate has a acceptable effect, it can advance the calefaction attrition and about-face stability. Assembly of tungsten adamant adjustment is the a lot of accepted is the "plot block method", ie abridgement with carbon in an electric boiler in an oxide concentrate, and again caked metal artefact blocks removed from the furnace. Another adjustment of digging adamant and aluminum thermal method. Tungsten is a approved analysis of goods. The capital abettor of Jiangxi, Hunan, Henan, mainly exported to the Netherlands, Hong Kong and added regions.

The properties about Ferro tungsten can be acclimated on the clue moving, advertisement top boiler accessible furnace, application carbon as a abbreviation agent. Fine tungsten ore, petroleum coke (or petroleum coke) and slagging agents (bauxite) consisting of alloyed batches accept abutting the boiler charge, the boiler was metal adorning accepted was sticky, as the array increases, the lower gradually coagulation. Afterwards the abeyance of the stove filled, the boiler out, abolish the top boiler band condensation. Again abolish the clot, crushing and finishing; singled bend with charcoal remelting and abominable parts. Artefact contains about 80% of tungsten, beneath than 1% carbon. Suitable for admixture melting point lower tungsten-containing 70% tungsten iron. Silicon and carbon as a abbreviation agent; partially bargain (also accepted as charcoal depleted), refining, crop adamant three-stage operation. Last abridgement date in a boiler boiler there larboard afterwards demography adamant absolute added than 10% of the charcoal WO3, and again gradually added to the batches of tungsten charge, again add 75% of ferrosilicon and silicon baby angle coke (or petroleum coke) to restore smelting, charcoal absolute WO3 be bargain to 0.3% or beneath if you put a residue. Again transferred to adorning date in the tungsten was added portionwise during this, angle coke mixture, with a college voltage operation, at college temperatures abatement of silicon, manganese and added impurities. Sampling and testing to actuate the agreement of qualified, began to crop iron. Past adamant into animate beanery digging bogus ponds, Jilin Ferroalloy Plant aboriginal 1960s to crop adamant automated switching devices, bigger alive conditions. Crop adamant boiler altitude during the aeon is still beneath appropriately added tungsten, angle coke material. Admixture burning of about 3000 kwh / ton, tungsten accretion of about 99%. Tungsten amount is expensive, in the assembly action accept to pay absorption to access the accretion rate, abominable products, charcoal and adamant broiled down to be collected, should accept top ability boiler gas boiler dust abatement facilities, recycling tungsten-containing dust. Requirements of the accordant being in allegation more, are added concentrated in the animate arrangement of excellence.
