What are Big Fireclay Bottom Blocks

Tin bath is the heart of the float glass production line, while the quality of tin bath Big Fireclay Bottom Blocks is the key structural material to the normal operation of the tin bath.

The big fireclay bottom block is generally large with a unit weight of over 50kg, even 400-500kg. The ordinary machine pressing method and ramming method are not suitable to its molding. The casting molding method is generally used. 

 

Using big vibrating table and adopting special castables, Big Fireclay Bottom Blocks ae made with vibrate molding technology. The physical and chemical properties and appearance of the blocks have exceeded the national standards. The resistant ability to molten glass of the products is better than that of traditional casting process products and ramming products.
