Refractory Clay Bricks T-3 For Electrolytic Bath Application: The Lining Of Acid Slag Furnace

Backed by rich industry experiences, we are leading Exporter, Manufacturer & Supplier of Refractory Clay Bricks T-3 For Electrolytic Bath in Zhengzhou, Henan, China.
Clay bricks are one of the main varieties in the aluminum silicate products. They are refractory products with the content of Al2O3 of 30% ~ 48% made of clay clinker as aggregate and refractory soft clay as binder.
The nature of clay products fluctuates over a wide range due to the wide range of chemical composition of the products (fluctuations in Al2O3 content of 30% to 48%) and differences in production processes. Refractoriness fluctuations at 1580 ~ 1700a ; its products better thermal shock resistance, wide range of fluctuations, generally greater than 10 times (1100a water-cooled); clay products, linear expansion coefficient; 20 ~ 1300a between the average linear expansion The coefficient is (4.5 ~ 5.8) A 10-6a -1.
Clay products are weak acid refractory products, with the increase of SiO2 content to make it acidic. It has a certain resistance to acid slag erosion resistance, and alkali corrosion resistance of slag is poor. Therefore, clay products should be used as the lining of acid slag furnace.
