Product Overview
Description
Product Description
Advantages
1.Waterproof and good moisture proof effect;
2.Low thermal conductivity;
3.High structural strength and low deformation after sintering;
4.Good heat preservation, reducing heat losses and saving energy, ensuring a smooth continuous casting process due to the constant temperature and casting rate of the steel;
5.Good volume stability, good ladle lining integrity, realizing the constant temperature and constant speed during steel casting, improving production efficiency;
6.Long time efficiency and energy saving, high safety;
7.Diverse sizes and shapes, no need to do post processing, easily to be installed.
The shell temperature of test ladle that takes Magnesium Silicon Thermal Insulation Board as liner is much lower than that of common ladle, which averagely reduces 75℃, while the maximum temperature reduction will be about 120℃. Therefore, the board application will facilitate to eliminate the deformation of ladle shell materials, and greatly improve operation environment of ladle. The temperature drop rate of molten steel is smaller than that of common ladle, namely average 0.3~0.5℃/min. It indicates that the heat preservation of molten steel is quite great, which can not only save energy and heat losses, but also is beneficial for the constant temperature and rate during steel casting process to ensure the smooth continuous casting.
Regular size for steel ladle & tundish
416X101X13~20mm
416X101/91X13~20mm
397X99/97X13~20mm
Applications
This product is mainly used for hat protection for steel ladle, tundish, torpedo car and electrolytic aluminal cell.
