Influence of Adding Trace Liquid Paraffin on Carbon Blending and Carbonization Effect of Ultra-coarse Tungsten Powder AITranslate
Abstract AITranslate
Taking ultra-coarse tungsten powder as raw material,and liquid paraffin as wetting agent,the double cone mixing method was used to evenly distribute paraffin on the surface of tungsten powder,and then powdered carbon black was added to the mixture for ball milling.Through analysis of different paraffin additions and carbon distribution uniformity,the influence of paraffin addition on carbon blending effect and total carbon content was discussed.The samples were carbonized under the same process conditions,the quality of the final product tungsten carbide was compared and analyzed,and then the influence of adding trace liquid paraffin on the carbonization effect of ultra-coarse tungsten powder was discussed.The results show that the addition of trace liquid paraffin can make the carbon black distribution more uniform after the tungsten powder is mixed with carbon,and it can also avoid tungsten-carbon separation during boat loading before carbonization.Meanwhile,compression forming is easier,and the tungsten-carbon combination is tighter,which improves the carbonization efficiency and quality,and can produce pure tungsten carbide with coarse grains.Liquid paraffin will decompose at high temperature to produce activated carbon,which combines with tungsten to increase the total carbon content and needs to be balanced during determining carbon amount.Excessive addition of liquid paraffin will result in carbon black aggregation and decreasd particle size of tungsten carbide.Comprehensively considering,when the paraffin content is 0.5‰~3‰,the effect is the best.
