Q: Is there a big difference between two high alumina brick and one high alumina brick?: According to my experience, two kinds of high alumina bricks from the index, there is a big difference between the content of AL2O3, a high aluminum brick in 75%, two grade high alumina bricks in 65%, so the content is not the same, also decided that the use of temperature difference, the difference is very big.

Q: What's the difference between a well type annealing furnace and a box type annealing furnace?: 1. The shell of the furnace is welded by section steel and steel plate. 2, the furnace cover support adopts steel and guide rail combination mobile type. 3. The heating element is made of high resistance alloy 0Cr25Al5 produced by Beijing Shougang Group and arranged on the furnace side. 4, because the bottom bearing adopts high aluminum bricks, the circle center of the furnace set small, inside and outside heating. 5 、 furnace cover adopts hydraulic lifting, motor control, automatic walking. 6 、 temperature control system adopts PID SCR control, high accuracy.

Q: What is the density of a super high alumina brick and what is the price?: Super high alumina brick, alumina content of 80% bricks, bulk density of 2.7g/cm3 or more, the factory price of about 1900 yuan

Q: How to make refractory bricks and boiler wall adhesion more firm?: If the condition, the user heat-resistant steel welding grip nails, expansion joints can not be too big.. Also to use high temperature aluminum brick, high temperature resistance, but also to extend its use cycle.

Q: Aluminum content 38, silicon content 55 What refractory bricks?: Hello Only on behalf of the Zhengzhou colt as refractory product index your answer to this question is not entirely separate from the chemical index of aluminum content, silicon content and judgment, personally think that three types of refractory bricks may respectively is: Two: semisilica brick high alumina brick

Q: Difference between low creep high alumina brick and ordinary high alumina brick: The question is good, these two belong to the high aluminum brick products, when many manufacturers buy, I do not know how to distinguish.

Q: How much is one ton / ton of high alumina refractory brick?: The market price of about super high aluminium brick price at 3000 yuan / ton, a high aluminum brick at around 2500 yuan / ton, two high aluminum bricks at around 2100 yuan / ton three grade high alumina bricks at around 1850 yuan / ton for reference, choose to buy the area is not the same as the prices are not the same.

Q: Does the chimney have high acid resistance?: If it is an ordinary high alumina brick, it does not meet the requirements of acid resistance, and only the chimney lined with acid resistant bricks.

Q: What is the difference between metal compounds and metal solid solutions?: A series of intermetallic compounds occurring between transition metals in intermetallic compounds. The most important are L sigma sigma phase and ves phase, they are topologically close packed (TcP) phase, they consist of a small atomic radius of a dense layer, which is inlaid with a large atomic radius of atomic structure, this is a highly dense pile. In addition to atomic size factors, their formation is also influenced by the concentration of electrons.

Q: What should be used as binder for making high alumina bricks?: Bond for making high alumina brick: soft clay has good plasticity, so the high alumina brick is usually made of soft clay as bond. However, the free Al2O3 free SiO2 and bauxite clinker clay in under 1200 degrees occurred two times of Mullization reaction, generate large volume expansion, silicon porosity, strength reduction. Therefore, the amount of clay powder in the ingredient should be no more than 5%.
