WebNov 4, 2024 · Refractory bricks are resistant to high temperatures, have a high fusion point, and have exceptional compressive strength. Each cubic foot of fire bricks weighs 150 lbs. A refractory brick measures 94.52.5 inches or 92.72.25 inches in size. Unrivalled chemical resistance is another benefit of refractory bricks. WebSo, M200 can withstand a load equal to 200 kg / cm2. Stones of grade below 100 are of too poor quality - they are covered with cracks, heterogeneous structure, irregular shape. Too strong masonry, although it looks flawless, is afraid of high temperatures, begins to delaminate during operation. Basic requirements for refractory bricks WebA low temperature fire first, then a full blaze normally 1200 degrees. Hercules held up to the temperatures without the joints reopening. This is more than expected because the expansion occurred without cracking again. These bricks have been under high temperatures for about 6 years and the cracks appeared on day one. importing pillows from china
