Henan high aluminum refractory price fluctuations is the main reason

So, when we choose, we need a comprehensive measure of Henan high alumina brick prices and use, so as to make our high alumina brick in life and work to play a more important role.

     Henan high alumina brick prices in the use of high-alumina brick to measure the quality, but also should be combined with the manufacturing process to control, that is, the appearance of high-alumina brick and the internal structure is dense. And these are with the ingredients of the particles with the molding pressure, the size of the brick is burned or burned and other factors are closely related. If the high alumina brick ingredients are highly refractory (or even above 1700 ° C), but the brick is not tight, and not sintered (loose), its life is bound to be very short, because this high alumina brick porosity , Poor strength, in use vulnerable to harmful liquid or gas erosion. Therefore, in determining the quality of high alumina brick (especially the use of quality), must be fully considered. The refractory index is only the first basis for the participant data.
The refractory degree is directly related to the chemical composition of the raw material. If Henan high alumina brick ingredients used in a variety of raw materials, you must pay attention to the purity of raw materials and their mutual influence. High-alumina brick manufacturers that generally in the clay brick ingredients on the main amount of clay clinker or barren clay (shrink small hard clay) fire resistance, determines the quality of high alumina brick. As a combination of clay (soft, clay) is usually a large shrinkage, low refractorability of raw materials, such as excessive use, will greatly reduce the clinker or barren clay fire resistance. In the manufacture of silica bricks, quartz sand is a refractory raw material, but because of the addition of a part of clay as a molding binder, and such clay may be lower refractoriness, so the fire resistance of the product must be lower than the quartz sand itself. Therefore, it can be said that the chemical composition of ingredients determines the high alumina brick fire resistance.
