CNBM has success in its refractory and insulating products due to their cost-effectiveness and excellent insulating properties. CNBM also has experience in refractory and insulating application and would like to assist you in product selection, system design, and installation techniques.
- Q:In 2016, a few of the traditional refractory materials will be able to survive
- The other is in large enterprises and individual has the unique advantage of the small enterprises, with independent technology system, production equipment advanced, there are certain funds set up to deal with risk, timely reform, such enterprises compared to a few years ago the productivity and sales or have declined, but overall is still in the stage of production increased steadily.
- 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: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.
- Q:What's the difference between high alumina refractory bricks and high alumina refractory bricks?
- High alumina refractory brick in all thermal shock properties except performance are better than clay refractory brick, masonry in furnace and thermal equipment, such as clay bricks can be competent the work environment is not high aluminum brick masonry.
- Q:How to distinguish the good or bad of the high aluminum brick?
- Weigh the weight of the next block. According to the weight standard, a high alumina brick is 3.9 kg in weight, two in high alumina brick, three in high aluminium brick and 4.5 kg in 4.2. The same grade, the same type of high alumina brick, if the weight of a single brick to this standard, but for high quality high alumina brick, otherwise, can not reach such a weight, it shows good quality. If there is a crack, a large piece of broken angle, four sides of inequality, it is for substandard products.
- 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:Application characteristics of high alumina brick
- Slag resistance. Due to the high alumina brick products in the three oxidation of two aluminum is neutral and high content, so this material products for acid-base slag corrosion resistance.
- Q:How are the grades of high alumina bricks differentiated?
- High alumina brick: aluminium silicate refractory product with a content of three Al2O3 (two) and more than 48%
- Q:What are the high temperature refractory mortars made of?
- Products used in metallurgy, building materials, machinery, chemical, power industry, industrial thermal furnace, for masonryBuilding clay brick, high alumina brick and corundum brick have the characteristics of full grey seam, good airtightness, high bonding strength, high temperature performance and suitable construction time
- Q:What's the weight of the refractory bricks?
- Fireclay refractory bricks: 3.4kg-3.8kg - according to the quality of raw materials, prices ranging from 1 yuan to 2.7 yuan, high alumina refractory brick: three, high aluminum in 3.9kg or so. Ordinary T-3 firebrick weight calculation method: 230*114*65*2.2/2.1.
