Curved fire brick is a semi-arc refractory brick, one end of the arc is a semicircle, the other end is a groove and it can be built into circles of different diameters according to actual conditions. This product is very suitable for masonry of circular furnace linings with tonnage of 10-200 tons such as ladles, teeming ladles and molten iron transfer ladles. The furnace lining built with this brick fits tightly. Adding refractory mortar during masonry can also fill the mortar joints and increase the saturation.
Features of Curved Fire Brick for Sale
1. Good Airtightness
The high temperature refractory brick joints can generally reach 1 mm, and its vertical brick joints are smaller, which is 70% less than standard fire bricks. It effectively improves the airtightness and stability of the circular structure.
2. High Flexibility
It can adapt to circular or curved structures. The roundness can be adjusted as needed. Even if there is a slight deviation in the size, it can be built into a circle.
3. Increase Capacity
For cylindrical kilns and furnaces, the curved brick can reduce the number of straight joints. Effectively increase the overall capacity and make the brick joints tighter.
4. Convenient Construction
For the construction of circular furnace linings, the curved fire brick is more convenient than the right-angle bricks, which can reduce labor and improve masonry efficiency.
Common Types and Applications of Curved Fire Brick
At present, the common curved fire bricks in Kerui factory are C19, C20, C21, C22, C23, C25, C27, etc., which are used to build circles with different radii. For teeming ladles, the capacity of different radii is also very different.
In addition, it is also widely used in blast furnaces, electric furnaces, hot blast furnaces, thermal boilers, glass kilns, cement kilns, fertilizer gasification furnaces, casting and steel pouring bricks, etc.
Masonry of Curved Firebrick
The masonry of curved fire bricks is usually to lay them one ring at a time in a climbing manner. This process is similar to the step-by-step method, not built layer by layer.
Before workers use this brick on your high-temperature kiln, it is usually necessary to use starting bricks to adjust the teeming ladles of different diameters to ensure the flatness and roundness of the masonry.
