The invention discloses a sintering method for a hard alloy blank, which relates to the field of hard alloy manufacturing technology, the hard alloy blank is a stepped shaft, degumming and sintering processes are carried out on the hard alloy blank, graphite blocks are padded at all shaft segments of the stepped shaft respectively, so as to make the axes of all the shaft segments of the stepped shaft maintained on the same horizontal line, all the graphite blocks are provided with grooves used for placing the shaft segments of the stepped shaft, and the grooves gradually shrink from groove openings to groove bottoms. The sintering method for the hard alloy blank can solve the problems the hard alloy blank with a stepped shape is easy to bend and deform during sintering, and the percent of pass is low.
