Abstract

The invention discloses a formula of an unfired honeycomb ceramic regenerator. According to industry routines, the formula is obtained through the steps of: firstly compounding a main formula according to the following raw materials in percentage by mass: 80%-86% of corundum mullite, 10%-12% of kaolin, 3%-5% of alumina micro-powder and 1%-3% of monox micro-powder; then compounding an auxiliary formula through using the total mass of the raw materials of the main formula as a benchmark, wherein the auxiliary formula comprises the following components in percentage by mass: 6% of chopped zirconium-aluminum ceramic fibers, 2.5% of carboxyl methycellulose and 0.5% of stearic acid; and then compounding liquid according to the total mass of the raw materials of the main formula and the auxiliary formula, wherein the liquid comprises the following components in percentage by mass: 20% of water and 5%-7% of aluminum phosphate. The invention further discloses a corresponding technology. According to the formula and the technology which are disclosed by the invention, a manufacture cost is lowered, energy consumption is reduced, a qualified drying rate of products achieves 98%, compressive strength is larger than or equal to 8MPa, and breakage requirements of transporting and mounting the unfired honeycomb ceramic regenerator are satisfied.

Description

technical field [0001] The invention belongs to a thick-walled honeycomb ceramic regenerator applicable to various heating furnaces, and in particular relates to a formula and a process of an unfired honeycomb ceramic regenerator. Background technique [0002] At present, the traditional formula and process for the production of honeycomb ceramic regenerators in the existing domestic technology are: corundum mullite + Suzhou soil + alumina micropowder (particle size ≤ 5 μm) + silica micropowder (particle size ≤ 5 μm) + hydroxyl Propyl methyl cellulose + water + grease lubricant, the production process is: batching → ball mill or V sub-shaped mixer dry mixing → kneader adding water and grease lubricant seasoning to make the mud into agglomerates → Vacuum mud refining → stale mud section → secondary vacuum mud refining → extrusion molding → microwave shaping → oven or drying room drying → cutting, soot blowing → kiln installation → product firing. The honeycomb ceramic regene...
