Second, another type is special shape refractory which is a new type of firebricks widely used in recent years.

Besides, special shape firebrick has three more grooves than ordinary type refractory. Third, this is a standard type firebrick. It is usually used for common furnace construction. If there are no other special requirements for brick bond, it’s better to use standard firebrick. For choosing refractories , we can not only select...

China series of industrial policies implemented, receive the positive response of waterproofing enterprises, waterproofing industry adjust the industrial structure in China, the implementation of macroeconomic regulation and control, promotion of new waterproof materials, the fight against fake and inferior products, standardize the market for waterproof and push forward technical progress in the sector, guide the healthy development of industry has played a powerful role in promoting.
