Classification of insulating refractory products

- Jan 11, 2018-

There are many kinds of insulating refractory products. Their classification methods mainly include the following kinds:
◆  According to temperature, it can be divided into low temperature heat insulating refractory (using temperature 600 ~ 900 ° C), medium temperature and heat insulation refractory (using temperature 900 ~ 1200 ° C) and high temperature heat insulation bio-soluble refractory (temperature greater than 1200 ° C).
◆  According to the volume density, it can be divided into general lightweight refractory (volume density of 0.4 ~ 1.0 g/cm3) and ultra lightweight refractory (bulk density less than 0.4 g/cm3).
◆  According to the production methods, it can be divided into burning method, bubble method, chemical method and the method of porous materials.
◆ According to the product shape, it can be divided into setting insulating bio-soluble refractory products and amorphous insulating refractory products.
