PRODUCT DESCRIPTION

Introduction

Vermiculite insulation board is a lightweight thermal insulation refractory processed with expanded vermiculite as the main raw material, bonded with inorganic binders and pressed into shape.

The vermiculite insulation board has a high structural strength, low deformation after sintering, good insulation properties and resistance to moisture. It retains its physical properties during operation at high temperatures. Installation of this board imparts volume stability to the complete lining, reduces the shell temperature of the furnace, and eliminates stresses within the bricks thereby ensuring safe operation of the furnace and effectively saving energy. This product is mainly used for applications in the metallurgical and building industries, for furnace insulation and for fire resistance, etc..

The shell temperature of a ladle in which magnesium silicate insulation board is used as the lining is much lower than that of a normal ladle. The average reduction in shell temperature is 75°C and the maximum reduction in shell temperature can be as much as 120°C. The use of this board therefore helps to eliminate deformation of the ladle shell and improves greatly the operating environment within the ladle. The rate of temperature loss of the molten steel is lower than that of a normal ladle, typically an average of 0.3~0.5°C/minute. This shows that the heat retention of the molten steel is quite high, thereby reducing heat losses and saving energy and also ensuring a smooth continuous casting process due to the constant temperature and casting rate of the steel.
