refractoriesHML insulating fire brick1. HML series Insulating Fire Bricks is evenly distributed with little porosity, and could reach high strength under high temperature and low Thermal conductivity at the same time ensuring the apparent porosity. Which possess low thermal capacity, low heat conductivity, high strength, etc, it can reduce heat absorption and energy consumption as well as shorten the working period.2. HML series insulating fire brick is suitable to the environment where the temperature varies between 1300 and 1550°C and divided into 4 grades.Mainly used for the furnaces and kilns of the insulating part and the lining far from the erosion of the megathermal meiting materials.3. Our products have being exported to the USA, Japan, Korea, Germany, United Kingdom, Taiwan and so on.4.
