FAQ
If I need your offer, what information do you need?
In order to choose suitable products, it will be appreciated to provide us the information, such us specification, technical data, order quantity, products application etc.
If any question, please contact us freely.
How do you control the products quality?
With strict quality control system throughout the materials selection and production process, our refractory and ceramic fiber products quality is effectively controlled to meet customer requirements.
From the raw materials selecting, our quality control begin. The quality certificates of raw materials are required and each batch will be tested before using. During production, the quality control are conducted by workers and then each piece will be sorted and examined by quality supervisor.
I’m not satisfied with the refractory materials I used before, can you propose more suitable pro
Yes. Please give us the problems you faced, your requirements and the technical data of the products you used before. That we will give you our suggestion and propose the solution based on your special requirements.
What’s the lead time for my order?
It depends on customers’ requirements and our production schedule. And usually we need 30-60 days for refractory bricks,10-25 days for unshaped refractory materials and 10-20 days for ceramic fiber blankets.
Can you offer Door-to-Door delivery?
Yes, but only for some countries such us U.S., UAE, Saudi Arabia, Iran, and Russia, etc.
What is the minimum quantity?
There is no minimum order quantity. Depending on the item and processing, there may be a minimum production required, however we can offer a quotation based only on the quantity you need.
- Q: How can the silica in zircon sand be removed during the smelting of zirconium corundum?
- How can the silica in zircon sand be removed during the smelting of zirconium corundum?The fused zirconia corundum brick is mainly made of fused zirconia and corundum. ZrO2-Al2O3-SiO2 three element system fused brick, containing Al2O3:40% to 50%, ZrO2:30% to 50%, SiO2:10% to 17%.
- Q: How are qualitative and qualitative refractories understood?
- Unshaped refractory products, referred to as bulk loading, are made at the place of use for the required shapes and for heat treatment, such as castable, ramming, projection, spray, refractory clay, etc..
- Q: What are the forming methods of refractory materials?
- Basically there are three kinds: grouting molding, casting molding, machine forming, the three methods are applicable to different types of refractory materials, grouting molding for unshaped refractory
- Q: Zirconium corundum 25 content and 40 content, how to distinguish in appearance?
- Fused zirconia corundum brick is also called AZS AZS English is abbreviated to AZS, is based on three chemical composition of Al2O3 - Zr02 - Sio2 phase diagram of three component system, according to the content of the order, Al2O3 A, Zr02 Z, Sio2 S, national standards for the use of this abbreviation, such as No. 33 cast brick, abbreviated as AZS, 33#, No. 36 fused zirconium corundum brick, abbreviated as AZS, 36#, No. 41 fused zirconium corundum brick, abbreviated as AZS - 41#.
- Q: What is the face brick
- According to the shape and size can be divided into ordinary brick, standard brick, etc. can be used as a specific type of building furnace and various thermal equipment of high temperature building materials and structural materials, and at high temperature can withstand all kinds of physical and chemical changes and mechanical action.
- Q: What are kiln bricks?
- Refractory materials are generally divided into two kinds, namely unshaped refractory and shaped refractory. Unshaped refractory castable is also called, is composed of a variety of aggregate or aggregate and one or more adhesive powder particles, and must use one or more liquid with stirring, has strong liquidity. Refractory materials generally refers to the shape of a refractory brick, standard rules, can also according to need to be cut when the temporary processing.
- Q: What are the main constituents of refractory bricks?
- According to the composition of refractory bricks, they can be divided into five major categories, namely, silicon aluminum refractory bricks, basic series refractory bricks, carbon containing refractory bricks, zirconium containing refractory bricks and insulating refractory bricks. Any furnace is not made of only one kind of refractory brick, and it needs different fire bricks to match with each other. The following five categories of refractory bricks are described in detail.
- Q: What are the specifications for bricks?
- Thecompressive node as a new type of building energy-saving wall materials, which can be used for masonry walls, but also has good thermal properties, in line with the construction of the building module, reduce the loss in the process of construction, improve work efficiency; the hole rate reached more than 35%, can reduce the weight of the wall, save the foundation engineering cost. Compared with common sintered porous brick, it has the characteristics of heat preservation, heat insulation, light weight, high strength and high construction efficiency. The product is made of shale as raw material. It is produced by high vacuum extrusion molding machine and one yard firing process
- Q: Outside wall tile (whole body smooth surface has small hole split brick) has cement pollution, with what product cleaning (cement, mortar, cleaning agent)?
- Ordinary brick size of 240 mm * 115 mm * 53 mm, according to compressive strength (Newton / square millimeter, N / mm2) size is divided into MU30, MU25, MU20, MU15, MU10, MU7.5, these intensity levels. Clay brick materials, cheap, durable, and fire prevention, heat insulation, sound insulation, moisture absorption and other advantages, is widely used in civil engineering. Waste brick can also be used as aggregate of concrete. In order to improve the shortcomings of ordinary clay bricks, such as small, self important and waste of soil, they are developing in the direction of light weight, high strength, hollow and big blocks.
- Q: What material is good for refractory bricks?
- 1, silicon aluminum refractory bricks mainly include the following.(a) is the main varieties of acidic silica brick, refractory brick. It is mainly used for coke oven building, also used in furnaces all kinds of glass, ceramic and carbon calciner, refractory brick arches and other load-bearing parts, is also used in high temperature bearing part of hot blast stove, but should not be used in thermal equipment below 600 DEG C and the temperature fluctuation in the.(two) clay brick is a refractory brick commonly used in blast furnaces, hot blast furnaces, heating furnaces, power boilers, lime kilns, rotary kilns, ceramics and refractory bricks.(three) the mineral composition of high alumina refractory brick and high alumina refractory brick is corundum, mullite and glass phase. The raw materials are high alumina and sillimanite natural ore. They are also made of fused alumina, sintered alumina, synthetic mullite and calcined alumina in different proportions with clay. It is produced by sintering process. But the products are casting brick, brick, brick fused grain and unshaped refractory brick. High alumina refractory brick is widely used in iron and steel industry, non-ferrous metal industry and other industries.
