Abstract

The invention relates to a refractory block for reducing the particle upper limit of andalusite, and relates to the technical field of refractory materials. A key technology of reducing the particle size of andalusite particles is adopted. The andalusite particles, sillimanite particles, alumina powder particles, silica powder particles and Guangxi clay particles are connected in a mutually-bonding, pressing and curing manner to form an integral block structure. The particle size of the andalusite particles is 1-2 mm. The refractory block is used as a refractory material. The conception is scientific and unique. The design is simple and ingenious. The structure is dense and durable. Raw material import is solved. Products have reduced defects, a high percent of pass, good quality and a low cost, thus facilitating popularization and application.

Description

technical field [0001] The invention relates to a refractory block for reducing the upper limit of andalusite particles, and relates to the technical field of refractory materials; in particular, it relates to the technical field of inorganic non-metallic refractory materials; in particular, it relates to the technical field of refractory blocks for reducing the upper limit of andalusite particles. Background technique [0002] Andalusite is a kind of Al that can be directly used to make refractory products without calcination. 2 o 3 -SiO 2 Department of refractory raw materials. Raw material of andalusite according to Al 2 o 3 The content can be divided into 53, 55, 57, 58, 59, 61% grades, Al 2 o 3 >58% are high-grade raw materials, Al 2 o 3 ≤58% are medium and low-grade raw materials. [0003] In the production of refractory products with known technology, coarse particles (1-3mm), medium particles (0-1mm) and fine powder (≤0.088mm) are usually used as raw mate...
