Цените на високите тухли от алуминиев оксид със същия материал варират . Това се дължи главно на разликите в плътността на тялото, формата и количеството, което може да причини значителни разлики в цените между огнеупорни тухли от един и същи материал .
Because for high alumina bricks of the same material, taking LZ-65 refractory bricks as an example, due to their special specifications and shapes, their prices will be several hundred yuan or even over a thousand yuan higher than those of standard-sized refractory bricks. Standard bricks are marked by the state in terms of size, while special-shaped bricks are generally used in small quantities and have strange shapes. If the quantity is small, the price will be several thousand yuan higher. Due to its strange shape, it is difficult to demold. During the production process, it is hard to form, the yield rate decreases, and the cost increases invisibly. Moreover, the quantity is small, with some even just a few bricks. The cost of molds is high, and it takes half a day to change the molds. Once the molds are installed and production continues, the molds need to be replaced, which increases the workers' wages. So, the prices of high alumina bricks of the same material are different due to different shape.
In addition, for high alumina bricks of the same material, if the volume density requirements are different and the load-softening temperature is also different, the price difference will be even greater. For high alumina bricks with the same 65% content, if the volume density and load-bearing requirements increase, the price will also rise accordingly. Just in terms of aluminium content, for the same aluminium content, due to the Увеличаване на физическите показатели, цената също ще се повиши съответно . Ако изискването за съдържание на желязо е ниско, цената също ще се увеличи съответно .
В обобщение е доказано, че цената на високите тухли от алуминиев оксид не може да бъде определена от един индикатор . Цената на огнеупорни тухли може да се реши само чрез различни физически показатели, форми и количества .
