The invention discloses a
coke oven low-aluminum lattice
brick and a production technology. The
coke oven low-aluminum lattice
brick is prepared from, by
mass, 30% of semisoft clay, 55% of flint clay, 15% of fire-clay
grog and 2% of additional organic binding agent sulphite
cellulose waste liquor. The lattice
brick is a low-aluminum product, the low-aluminum product is a semi-acid
refractory product, the size of the product is stable under the high temperature state, the alkali
atmosphere resistance is high, the load
softening point is high, the high temperature using strength is improved, and the brick is suitable for being used for a
coke oven chamber bottom, a heat storage chamber and a perforated strainer; due to the design, the defect that an original material
coke oven lattice brick is frequently deformed and blocked is overcome, the novel material is adopted, the service life of the lattice brick can be prolonged, normal heat exchange of a
coke oven is smoothly ensured, and coking production stability is effectively guaranteed and supported.
