Abstract

The invention discloses a Sai Er brick and a manufacture process thereof. The Sai Er brick comprises a bearing brick body and an insulation core movably arranged therein. The bearing brick body is made by sintering an assembly of a left brick body and a right brick body; two ends of each of the left brick body and the right brick body are bearing portions; the bearing portions of the left brick are provided with a through hole; the insulation core movably penetrate the through holes and has one end extended into the bearing block body. The adjacent brick bodies are suitable for use in reversible manner; the brick bodies and the insulation core can be tightly fitted via trapezoidal shapes; building structures made with the brick bodies are more stable; an insulation vacuum cavity in the insulation core can relieve heat loss; the insulation cavity and an empty cavity in the bearing brick body can cooperate to improve heat storage and thermal insulation effects.

Description

technical field [0001] The invention belongs to the technical field of refractory materials, and in particular relates to a Searle brick and a manufacturing process thereof. Background technique [0002] Purcell brick is a refractory material made from andalusite, which is widely used in unshaped and shaped refractory materials, kiln furniture, and special ceramic materials. In the process of kiln construction, the existing bricks have a simple structure. Usually, solid bricks or bricks with through holes are directly used. Such bricks have poor thermal insulation and heat storage effect, which greatly increases the energy consumption of the kiln. Contents of the invention [0003] The object of the present invention is to provide a Searle brick and its manufacturing process, so as to solve the problems raised in the above-mentioned background technology. [0004] In order to achieve the above object, the present invention provides the following technical solutions: a Sea...
