Honeycomb body used for regenerative heating furnace and production method of honeycomb body used for regenerative heating furnace

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.

Description

technical field [0001] The invention belongs to the technical field of metallurgical refractory materials, and relates to a heat storage body for heating furnaces in the iron and steel industry and a preparation method thereof. More specifically, it provides a honeycomb body for heat storage type heating furnaces and a preparation method thereof. Background technique [0002] The regenerative heating furnace develops very rapidly in the metallurgical industry and is welcomed by many iron and steel enterprises. The energy saving effect is very significant and meets the requirements of my country's industrial development. The regenerator is the key part of the regenerative heating furnace. The honeycomb body is a refractory product with a reasonable structure and high heat exchange efficiency among the regenerators currently used. Due to its large unit area, large heat storage and fast heat exchange speed , energy-saving effect, simple supporting equipment and other characteri...

AI Technical Summary

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
