Method for quickly judging refractory brick quality

Method for quickly judging refractory brick quality

1. Intuitive method. Just take out a few refractory bricks and observe the surface. There will be black spots on the surface of the refractory bricks. This is unavoidable and is a normal phenomenon. However, the more black spots on the surface of the refractory brick, the more impurities, the worse the quality and performance, and the shorter the service life of the refractory brick lining.

The shorter the time to replace the refractory bricks. Observe whether the corners around the refractory bricks are missing, and check the brick surface for cracks.

2. Touching method. Directly touch the surface of the refractory brick to check whether it is rough. The surface of a good refractory brick is smooth and smooth to the touch, and the color is evenly distributed, while the surface of the poor quality refractory brick is rough and slag, and the color is unevenly distributed.

3. Weighing method. Each refractory brick has a size. For example, the size of a standard refractory brick is 230*114*65mm. Refractory brick manufacturers provide physical and chemical indicators for each refractory brick. Check the volume density value. Multiply the volume density by the size of the refractory brick to equal the weight of each refractory brick. Chongyang inspects a few pieces, weighs them with an electronic scale, and checks whether they are qualified (not too much deviation).
