Q:In 2016, a few of the traditional refractory materials will be able to survive
From the year 2015 to the year 16 the end of the year, refractories industry presents two kinds of situations: one is a small business, a single product variety and equipment, to meet the demands of both environmental protection and the downstream market, such enterprises are generally in the Qing state inventory;
Q:Corundum, high alumina and fireclay refractory difference is what
Corundum is unknown. The high alumina brick has higher aluminum content than the clay brick, and the temperature resistance is higher than 300 degrees. It is more durable and durable than the clay brick. The production process of high alumina brick is better than that of clay brick. For example, the weight of good clay brick is 3.7kg, and that of high alumina is 4.2kg. Good density. But the price of high aluminum is too high: ordinary clay brick (standard brick example) in 1.1--2.5 yuan / block, high aluminum to 4.5 yuan / block, or even more expensive. The extra high aluminum has reached 5000 tons. Say straight white point is: under the same conditions, clay brick for a period of one year, then the high aluminum for more than three years.
Q:The difference between clay bricks and clay bricks
According to the hole rate: solid brick (no hole or hole rate less than 25% bricks), porous brick (hole rate is equal to or greater than 25%), the size of the hole is small and the number of bricks, usually used in load-bearing parts, higher strength level. Hollow brick (hole rate equal to or greater than 40%, large pore size and small amount of brick, commonly used in non load parts, low strength grade).Solid bricks and porous bricks are mostly used for load-bearing structural walls. Hollow bricks are mostly used in non load bearing structures.
Q:Which is faster for heat transfer between corundum bricks or high alumina bricks?
There must be a difference. They vary in color from the amount of aluminum, the weight, the temperature, and the color.
Q:What is the price of the latest thermal insulation material?
There are many kinds of insulation materials, and the price will fluctuate with the market. Small quantities of inquiry or procurement, then go directly to the local thermal insulation market, a wide variety of prices are basically the market price.
Q:How many cubic bricks does a high alumina brick have?
It is related to the content of aluminum in high alumina bricks.
Q:How are the grades of high alumina bricks differentiated?
In China, the content of Al2O3 in high alumina brick is usually divided into three categories: I, etc. - Al2O3 content > 75%; II, etc. - Al2O3 content is 60 to 75%; III and so on - Al2O3 content is 48 ~ 60%.
Q:What are the grades of high alumina bricks?
According to the size of high aluminum brick is divided into: standard brick, special-shaped brick.
Q:What are the requirements for Rubble backfill height?
1, filling thickness is not greater than 50cm.2, filling, the use of layered filling.
Q:What are the reasons for the decline in the performance of high alumina bricks when we use high alumina refractory bricks?
The brick Pei boring and time. 6, Pei brick kiln installed between the brick and the brick Pei order, Pei and kiln top, kiln wall gap etc.. 7, high alumina brick kiln plan, and the lack of edges and corners of the scene should be avoided.
