The invention discloses a honeycomb body used for a regenerative heating furnace and a production method of the honeycomb body used for the regenerative heating furnace. According to the honeycomb body, high bauxite and pink funsed alumina are adopted as main components, clay is adopted as a binder, silicon carbide, silica powder and alpha-Al2O3 powder are added, a sintering aid, a toughener, a lubricant, a plasticizer and a high-temperature binder are added at the same time, and through technology steps of mixing, vacuum pugging, extrusion, forming drying, firing and the like, the honeycomb body used for the regenerative heating furnace is produced. The honeycomb body meets the technology requirements of a regenerative combustion technology, has performance of large heat storage capacity,stable high-temperature performance, high heat exchange efficiency and a long service life, the number of times of blowing out due to replacement of honeycomb bodies of a steel plant can be decreased, the production operation rate of the heating furnace is improved, the equipment maintenance cost is reduced, and effects of increasing production and practising economy are truly achieved, so that the honeycomb body used for the regenerative heating furnace has obvious economic benefits and very wide use prospects.
