Preparation method of metal ceramic composite wear-resistant material
The invention relates to a preparation method of a metal ceramic composite wear-resistant material. The preparation method comprises the following steps of: adding calcium oxide, a reducing agent cokepowder with granularity of 0.7-3 mm, magnesium fluoride, potassium fluoride and calcium fluoride into copper smelting tailings; reducing metal iron powder under the condition that the reduction temperature is 1100 DEG C, the reduction time is 2 hours and the rotating speed of an oven is 20-80 revolutions per minute; putting the metal iron powder into an intermediate frequency furnace, setting thetemperature to be 1580 DEG C, putting silicon carbide, boron carbide, borax, brown fused alumina powder and graphite after the metal iron powder becomes a solution and carrying out stirring for 5 minutes; finally adding nano silicon dioxide, titanium dioxide, ammonium fluoride, rare earth magnesium and niobium and carrying out stirring for 10 minutes; and carrying out water quenching at 900-1100DEG C and tempering at 200 DEG C to cast the metal ceramic composite wear-resistant material. The preparation method has the advantages of wear resistance and corrosion resistance; and meanwhile, reactant slag generated in the iron powder refining process can be reused, so that a new way is provided for utilization of the copper smelting tailings.
一种金属陶瓷复合耐磨材料的制备方法,在炼铜尾矿渣中加入:氧化钙、颗粒度0.7-3mm的还原剂焦粉、氟化镁、氟化钾、氟化钙;还原温度1100度,还原时间为2小时,烘炉转速每分钟20一80转,还原出金属铁粉;金属铁粉放入中频炉中,温度设定为1580度,待金属铁粉变为溶液后放入碳化硅、碳化硼、硼砂、棕刚玉粉、石墨,搅拌5分钟最后加入纳米二氧化硅、二氧化钛、氟化铵、稀土镁、铌,搅拌十分钟;再进行900-1100度水淬,200度回火处理,铸造出金属陶瓷复合耐磨材料。本发明具有耐磨、耐腐蚀的优势,同时提炼铁粉过程中所产生的反应物渣还可以再次利用,为炼铜尾渣的利用提供了新的途径。
