The invention belongs to the field of grinding wheel manufacturing, and particularly relates to a vertical type grinding wheel sintering device which comprises height adjustment support legs, a bracket, a center post and support trays. The vertical type grinding wheel sintering device has the benefits as follows: a high temperature resistant material is adopted, a grinding wheel is enabled to be positioned at the central position of a furnace, the two largest surfaces of the grinding wheel are directly irradiated by electrical heating elements on the two sides in the furnace, the grinding wheel is heated evenly when being sintered, a plurality of grinding wheels can be sintered at a time by adopting the combinational design, and the sintering efficiency is improved.
