Pemasok yang Diaudit Low Porosity Refractory Large Size Fire Clay Bricks For Glass Melting Furnaces:
By using big vibrating table and adopting special castables, the TK BRICKS produces furnace large fire clay blocks with
vibrate moulding technology.
The physical and chemical properties and appearance of the blocks have exceeded the national standards.
The large clay brick at the bottom of the glass furnace has better physical and chemical property and appearance than
other similar products.
Its resistant ability to molten glass of the products is better than that of traditional casting process products and ramming products .
The products are especially suitable to build the bottom of furnace, cooling and working end side wall of glass furnace.
Applications:Used for glass furnace bottom and wall and so on.
