Refractory plastic

Detailed introduction

The refractory plastics have the characteristics of high strength at medium temperature and high temperature, good thermal shock resistance and spalling resistance. They can be used in heating furnace for more than 20 years, but the construction is troublesome and the baking time is long. This product is mainly used for repairing the lining of thermal equipment and occasional use of heating furnace roof, such as Tangshan Liguo Rolling Mill, Jinshi, Yushun Long and so on.
