在自动焊和半自动焊工作中,我们把废弃的熔渣又重新利用,对节约焊剂,降低成本有一定的意义。熔渣利用的方法是:先把熔渣压碎、过筛,粒度应保持在0.5～2.5毫米,不宜过细(细粉末可与焊剂掺合作熔剂垫使用);用80%的熔渣与20%的焊剂搅拌均匀,在烘干炉内烘干1小时,再把温度升高到200～300℃保持 In the automatic welding and semi-automatic welding work, we put the abandoned slag and reuse, to save flux, reduce costs have some significance. Slag utilization method is: crushed slag, sieved, particle size should be maintained at 0.5 to 2.5 mm, not too thin (fine powder can be mixed with the flux flux mat used); with 80% slag and 20% Of the flux stir, dried in a drying oven for 1 hour, then the temperature was raised to 200 ~ 300 ℃ to maintain
