Abstract
The invention discloses an integrally-cast ceramic burner of a hot-blast stove. The integrally-cast ceramic burner is manufactured through the following raw materials in parts by weight: 50-80 parts of electrocast mullitewith the particle size of 8-0mm, 10-20 parts of electrocast mullite with the particle size of 120-180 meshes, 5-15 parts of silicon carbide with the particle size of 180-320 meshes, 5-10 parts of alpha-Al2O3 micropowder with the particle size of 0.5mu m, 5-10 parts of pure sodium calcium aluminate cement, 0.05-0.4 parts of trimeric sodium phosphate and 3-8 parts of water. According to the invention, the entire ceramic burner is integrally cast on a stove body construction site by adopting the integral casting technology and a high-tech casting material combined with the micropowder, the integral structure is stable without weak link, the heat shock stability and the high-temperature volume stability are good, no expansion and shrinkage occurs at the temperature of 1400 DEG C, a complex structure which cannot be made through bricking is realized, the construction is easy, and the cost is low.
Description
Technical field
The present invention relates to a kind of integrated poured ceramic combustor of hot-blast stove.
Background technology
The top ignition ceramic burner is built with the brick formula is brick for a long time always, and structural stability is poor, and there is weak link in brickwork joint; Easy of crack causes that string leaks, and difficulty of construction is high; Structure is limited to, though improved thermal shock resistance with the trichroite brick, the pyritous volume stability is bad.
Summary of the invention
The technical problem that the present invention will solve is that the top ignition ceramic burner is built with the brick formula is brick, and structural stability is poor, and a kind of integrated poured ceramic combustor of hot-blast stove is provided.
Technical scheme of the present invention is: a kind of integrated poured ceramic combustor of hot-blast stove, and it is to be processed by the raw material of following parts by weight:
