Do you know that the depth of chrome corundum bricks and corundum bricks with different Cr2O3 content will be different by the erosion of glass slag?
Tests show that when Cr2O3<17%, the higher the Cr2O3 content in the brick, the shallower the depth of glass slag intrusion. In order to further clarify the erosion of corundum slag on corundum brick and chrome corundum brick, sunrise refractory material has been tested for slag resistance. The test shows that corundum brick is seriously eroded by slag, and the slag is completely infiltrated into the brick. The internal pores of the brick penetrate into the surface, the brick turns brown, and there is almost no slag residue; the chrome corundum brick is hardly eroded by the slag, and there is no obvious chemical reaction between the slag and the brick surface. The edge of the inner hole and the residue are clearly defined, and the residue penetrates into the brick. Rarely, only about 5 to 10 mm thick metamorphic layer is formed around the brick hole, and a large amount of slag remains in the pupil.
Through theoretical analysis and practice, it is proved that the chemical corrosion and permeability of chrome corundum brick anti-gasifier slag are better than corundum brick, and the anti-structural spalling property is superior to corundum brick.
