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?
- Fused zirconia corundum brick is pure alumina and zirconia containing silica 65%, about 34% of the zircon sand in electric furnace melting after internalization into moulds cooling and the formation of the white solid, the petrographic structure by zirconium corundum and plagioclase eutectoid and glass phases, from the phase is eutectoid zirconium corundum and plagioclase phase, glass phase filling between their crystallization.
- Q: What is brick power, half brick power and full brick power difference?
- All brick power up to 500 watts up and down. The internal circuit is tight and heating, the device has good adhesion, the circuit is more advanced, and the efficiency is high, so it can achieve small size and high power.
- 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 are the categories of bricks?
- Fired shale brick as a new 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, loss and high 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, the Jian Ling brick 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: 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: Just what is in the furnace material?
- Referred to as refractory brick. Refractory made from refractory clay or other refractory material. Light yellow or brownish. The utility model is mainly used for laying smelting furnaces, and can withstand high temperature between 1580 DEG C and 1770 DEG C.
- Q: What are ordinary bricks, refractory bricks, hollow bricks?
- Material. Light yellow or brownish. The utility model is mainly used for laying smelting furnaces, and can withstand high temperature between 1580 DEG C and 1770 DEG C. Also called brick. Refractory material of a certain shape and size.
- Q: What material is good for refractory bricks?
- No definite answer can be given, because any furnace is not made of only one refractory brick and needs a different fire brick to be used with each other.
- Q: What's the use of refractory bricks?
- Refractory bricks are mostly used in the lining of furnaces of high temperature industries. Such as iron and steel industry, blast furnace, hot blast furnace, converter, colored reverberatory furnace, rotary kiln, etc.
