FAQ

Q1:Are you a manufacture or trader?

A:Factory+trade(mainly factories, at the same time,we operates other related products).

Q2:Can we visit your factory?

A:Sure,welcome at any time, seeing is believing.

Q3:What's the MOQ of trial order?

A:No limit,We can offer the best suggestions and solutions according to your condition.

Q4:Which payment terms can you accept?

A:T/T,L/C are available for us.

Q5:After an order is confirmed, when to deliver?

A:15-25days after deposit.

Q6:Is your company accept customization?

A:We have own factory and excellent technical team,and we accept OEM service.

Q7:How about your company's certification?

A:ISO9001 and Test Report,also we could apply other necessary certification.

Q8:How to slove the quality problems?

A:If the products are not confirmed to customer samples or have quality problems,our compay will be responsible to make compensation for it.

Q9:Can you offers samples?

A:Of coures,samples are free but freight paid by the buyers.

Q10:What is the service life of your bricks?

A:The service life of different bricks is unlike.It also depends on your using condition and method.

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:Application characteristics of high alumina brick
Refractoriness. High alumina brick products are advanced varieties of aluminium silicate refractory products, and their refractoriness increases with the increase of Al2O3 content, generally not less than 1750 - 1790 DEG C. If the content of Al2O3 is more than 95% of corundum brick, the refractoriness can be as high as 1900-2000 degrees.
Q:What is the standard classification of high alumina bricks and high alumina bricks?
High alumina brick is one of refractory materials. The main component of this kind of refractory brick is AL2O3. High alumina brick refractory clay brick and brick than refractoriness to high. It belongs to high refractory. High alumina brick Al2O3 more, close to the neutral refractory material, can resist acid slag and alkaline slag erosion, because it contains SiO2, so the ability of alkaline slag resistance than acid resistant slag ability is weaker.According to the number of AL2O3 content is divided into, 55,65, 75,80 and so on several grades.
Q:What causes breakage of refractory bricks?
Refractory brick is a non metal mineral products can be used in the high temperature of 1550 DEG C under belongs to a class of inorganic, used in high-temperature furnace lining materials as protection kiln, which causes damage, usually have these points.Furnace temperature is not clear, there is no corresponding choice of refractory bricks.Physical impact, abrasion and erosion cause damageChemical factors, especially chemical industry, should be made of refractory bricks, which should be resistant to penetration and erosionIV: products from the factory when the factory did not pass the quality inspection standards
Q:What refractory material does cupola lining use?
A class of inorganic nonmetallic materials with a refractoriness of not less than 1580 degrees. Refractoriness is defined as the temperature of a sample of a refractory cone sample that resists high temperature without loading and does not soften and melt down. But only in terms of fire resistance can not be fully described refractories, 1580 degrees of temperature is not absolute.
Q:The difference between ordinary and diatomite brick refractory brick
Refractory brick belongs to a large class, according to different materials used are divided into: high alumina brick, dolomite brick, magnesia chrome brick, magnesia spinel brick, phosphate brick, carborundum brick, brick, mullite bricks etc..
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:What are the reasons for the decline in the performance of high alumina bricks when we use high alumina refractory bricks?
All the raw materials adding order, mixing time, material and material moisture trapped. 4, the pressure and the volume density of Pei brick and brick Pei size etc..
Q:How to reduce the harm caused by two times mullite in high alumina refractory material
Two times mullite refers to the content of aluminum is about 70%, in high temperature sintering, the expansion coefficient is large, the thermal expansion rate is high.
Q:What is the price of the first grade high alumina brick?
The specifications and different prices, relatively large fluctuations of the main push of the refractory Dongxin high alumina brick high alumina brick prices generally around 3000 have various levels of Dongxin refractories
