Abstract
In this paper, the benefits and deficiencies of substituting paraffin for butadiene sodium rubber as the lubricants used in the production of cemented carbides are studied. On the base of experiments and commereal production practice processing parameters for paraffin(including proper selection of the types of paraffin, admixing methods, weight admixed, control of the carbon contens in mixtures shrinkage coefficients of green compacts, presintering for dewaxing, Sintering and etc.)were discussed. The economic results obtained by using paraffin were listed and the trends to further improving, the processes were given.
