Problems solved by technology

[0003] The existing kiln furniture has poor thermal shock stability, unstable volume, low normal temperature flexural strength, and weak high temperature deformation resistance, resulting in short service life and poor use effect
Generally, after more than 2,000 times of kiln recycling, it will crack and damage, resulting in deformation, slag and other problems of porcelain. In severe cases, the kiln may even be inverted, which is a serious waste of resources and reduces production efficiency.

Abstract

The invention discloses an energy-saving kiln material and a preparation method of the energy-saving kiln material. The energy-saving kiln material is prepared from the following intergradient in proportioning: 35-42% of alumina, 50-58% of silicon oxide and 6.5-8.5% of magnesium oxide. The preparation method comprises the following steps of ball-milling, screening, further ball-milling, casting molding, sintering and the like so as to obtain the energy-saving kiln material ultimately. The kiln material is high in normal temperature breaking strength and strong in high temperature non-deformability, and can be widely used in kiln furnaces with large bearing quantity and long service life; by utilizing the product, the output can be improved, and the consumption of raw materials and energy is reduced with high efficiency, energy conservation and production cost conservation; and the production process is simple, so that the energy-saving kiln material is applicable to large-scale production.

Description

technical field [0001] The invention relates to the field of kiln furniture materials, in particular to an energy-saving kiln furniture material and a preparation method thereof. Background technique [0002] Sintering ceramic blanks is one of the necessary steps in the production of ceramic products. Kiln furniture plays a role in supporting and protecting the blank during the firing process of ceramic products. Its performance is related to the quality of the fired product and the amount of energy consumed, thus affecting the firing cost. Therefore, the kiln The quality of furniture plays a decisive role. [0003] The existing kiln furniture has poor thermal shock stability, unstable volume, low normal temperature flexural strength and weak high temperature deformation resistance, resulting in short service life and poor use effect. Generally, after more than 2,000 times of kiln recycling, the kiln will crack and be damaged, resulting in problems such as deformation and ...
