Abstract

The invention discloses a high-thermal-shock-resistance and long-service-life sagger and a preparation method, and relates to the technical field of sagger preparation. The sagger is prepared from thefollowing raw materials by weight: 100-140 parts of silicon carbide, 52-60 parts of mullite, 28 parts of spinel, 9 parts of graphite, 26 parts of zirconium oxide, 11 parts of steel fiber, 8 parts ofmagnesium oxide, 4 parts of calcium oxide and 5 parts of aluminum alloy. The sagger green body prepared by the method is compact, high in mechanical strength and high-temperature structural strength,and good in slag resistance, has continuously expanding application range, high refractoriness and high-temperature load softening point, good thermal conductivity, high thermal stability, long service life, no deformation or cracking at high temperature and small contractibility at high temperature, so that the stability of a product at high temperature is guaranteed, the thermal conductivity isgood, certain gas permeability is achieved, and heat and atmosphere at high temperature can be guaranteed to be rapidly transmitted to the product.

Description

technical field [0001] The invention belongs to the technical field of sagger preparation, and in particular relates to a high thermal shock and long-life sagger and a preparation method thereof. Background technique [0002] The sagger is one of the kiln furniture. In the process of firing ceramics, in order to prevent gas and harmful substances from damaging and fouling the body and glaze, the ceramics and body are placed in a container made of refractory material and fired. This container is called a sagger. , also known as saggers, using saggers to fire ceramics can not only increase the amount of firing, prevent the products from sticking, and increase the yield of finished products, but also has certain thermal conductivity and thermal stability, which can ensure the quality of ceramics. The shape of the sagger varies according to the shape of the utensils. The sagger is a round bowl of various specifications made of refractory mud and roasted at high temperature. Al...
