Our company is the earlier one of several factories only to produce refractory balls. Refractory ball is one of patent products.and developed by us with great concentration for 10 years.
Refractory ball were efficiently used in iron and steel factory in China,such as Kunming steel , Jiuquan Steel, Liuzhou steel, Daye steel,etc., and wined good praise from customers.
Product Description:
Refractory balls are made of industrial alumina and refractory kaolin as the main raw materials, which are made by scientific formula, forming and hightemperature calcination.
Refractory porcelain ball is divided into ordinary refractory ball and high aluminum resistance ball. Refractory porcelain ball high temperature resistance to high temperature can reach 1900 degrees, high mechanical strength and long-term use.
