Problems solved by technology

Many honeycomb bodies currently in use are not effective in metallurgical heating furnaces due to unreasonable material selection or formula. Crushing, burning of the honeycomb body due to poor flue gas erosion resistance, etc. These problems lead to a short life of the honeycomb body, which seriously restricts the performance of its heat storage performance, and also affects the quality of the heat storage furnace and the normal operation of the equipment

Embodiment 1～4

[0035] The raw materials of the honeycomb body for the regenerative heating furnace of each embodiment of the present invention and their contents in parts by weight are listed in Table 1, and the preparation methods of Examples 1-4 are the same. The above-mentioned various raw materials were weighed and prepared according to the ratio shown in Table 1, and water was added to the mixer to mix them thoroughly, and stirred into a mud-like material. The honeycomb bodies for regenerative heating furnaces of Examples 1 to 4 were obtained by putting them into a kiln for rapid drying, then grinding them, drying them again, and finally putting them into a high-temperature kiln at 1400° C. for firing.

Abstract

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.
