Product description
30mm fire bricks is a common refractory material with good fire resistance, corrosion resistance and mechanical strength, and is widely used in various high-temperature environment of industrial equipment, furnaces and buildings and other fields.
30mm fire bricks have good fire resistance: clay firebricks have good high temperature resistance, usually can withstand high temperatures above 1000℃, and some can even reach high temperatures above 1500℃.
Advantages of 30mm fire bricks
30mm fire bricks made by CH refractories with various size and free mold charge to meet different kiln applications. To be professional refractory blocks manufacturer since 1984, CH refractories also can design heat resistant bricks for sale, size according to your kiln drawing for free, and suggest you the most economical refractory bricks price for your kiln..
30mm fire bricks have good processing performance: The manufacturing process of clay firebrick is relatively simple, the material is easy to process and form, and the delivery time is fast.
