Abstract

The invention discloses an energy-saving kiln and preparation method thereof. The weight and percentage of components used for energy-saving kiln are as follows: SiSiC:85%-98%; Al2TiO5:0.15%-10%; B4C:0.1%-3%; Si2ON2 or Si3N4: 0.1%-3%; adhesive: 0.13%-3.5%; the balance is water, and the total amount is 100%; wherein the SiSiC is a mixture of particles with a particle size of 5-95 and a fine powderwith a particle size of from 130-380; the Si2ON2 or Si3N4 and Al2TiO5 are micro-powders with a particle size of less than 9 micrometer. The energy-saving kiln and preparation method can solve the problems of complicated production technology, high equipment requirements, large investment, high production cost, and the like in the market promotion process of silicon nitride and recrystallized silicon carbide products in the prior art, and the energy-saving kiln furniture prepared by the invention has high temperature resistance. The energy-saving kiln and preparation method has the advantagesof energy saving (natural gas saving), small volume, small deformation, light weight, high strength, strong oxidation resistance, regular appearance and remarkable service life.

Description

technical field [0001] The invention relates to energy-saving kiln furniture and a preparation method thereof, belonging to the technical field of refractory materials. Background technique [0002] At present, the production of kiln furniture in my country's ceramic industry has a long history. It is used to support and protect refractory products in the firing process of ceramic products. Its performance and quality are directly related to the ceramics to be fired. Products, but also have a great impact on firing costs, so the quality of kiln furniture is very important. [0003] Kiln furniture is a special-shaped refractory material used to support and protect products in the firing process, which has an extremely important impact on product quality and energy consumption. Correspondingly, the existing kiln furniture has poor thermal shock stability, unstable volume, short service life, and poor use effect. Generally, after 2000 kiln cycles, it will be cracked and damaged...
