Qualified Manufacturer Zibo Hitech Magnesia Chrome Brick

Production & Quality

1.Production Process

Crushing→Mixing→Shaping→Drying→Firing→Inspection→Packing shipment


2.Quality Control

a.According to the chemical content,raw materials are classified into different levels to ensure quality of brick first.

b.During the production,every brick will be weighed twice strictly to reduce the error of weight .

c.Before delivery, the inspectors will inspect the size,appearance,physical and chemical properties of brick again in factory.




F&A

Q1.Are you a manufacture or trader?

A:To be honest we are a trader,but we have stable cooperation factories.And we can supply good pre-sale service, after-sales service.

Q2.Can we visit your company?

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

Q3. Do you provide samples?

Yes, samples are available.

Q4. Do you accept OEM?

Yes, we can do OEM.

Q5.What's the MOQ of trial order?

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

Q6.What are the payment terms?

Usually T/T,but L/C,Western Union etc are available for us.

Q7. How long is delivery time?

The delivery time will be determined according to the quantity of the order.

Q8.How are your products’ quality?

The products will be strictly inspected before shipment, so the quality could be guaranteed.

Q9.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.

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.

Q11.How about your company's certification?

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





Q: What are the reasons for the spalling of refractory bricks in the production of lime kiln?
Therefore, the choice and masonry of refractory bricks are of vital importance. If there is a brick kiln kiln off block process of reproduction, is now because of the use of refractory brick kiln material mostly three grade high alumina bricks. The content of AL2O3 is about 55%, of which the content of Fe2O3 is about 2%, which is weak, and the alkali corrosion resistance is a little worse. In a containing three grade high alumina bricks in the composition of AL2O3, Si2O3, and other elements also contain K, Na trace, were the most, thus causing the system of the low melting point is very low, even at 1400 DEG C has been liquid phase, and generate CaAL12O19 limestone and calcium feldspar etc.. Form corrosion loss. Therefore, a long time will cause the loss of block. On the one hand, it may be caused by construction.
Q: How much is one ton of high alumina refractory brick?
High alumina refractory brick according to the different content of AL2O3 is divided into grade, grade one and grade two, and grade three high aluminum brick, Zhengzhou Kang Hui refractories factory price in 800-1900 yuan / ton, stable quality, are exported to the domestic and foreign markets.
Q: How many cubic bricks does a high alumina brick have?
Different content of aluminum, different proportion, weight is not the same. General grade T3 standard brick, 4.3~4.5kg, aluminium content 75. T3 size 230*114*65mm.
Q: Can high alumina brick resist carburizing?
Louzhu can use heavy impervious material, it is neither high alumina brick nor mullite, this product can resist seepage and have good compressive strength
Q: Are there any differences between insulating bricks and refractory bricks?
Heat preservation brick is to emphasize its heat preservation performance generally, not paying much attention to its refractoriness, but refractory brick is exactly the opposite. Different locations will use different materials, I hope we can choose carefully.
Q: How high can aluminum bricks expand at 80O degrees of heat?
When an object is heated, the particle moves faster and thus occupies additional space. This phenomenon is called dilation.
Q: How to reduce the harm caused by two times mullite in high alumina refractory material
Prolong the sintering time and adjust the aluminum content of the high alumina brick.
Q: How does the physicochemical index change when the high alumina brick is used at high temperature?
If the range of softening temperature exceeds the load, the constants of other physical and chemical indexes will also increase or decrease.
Q: Which thermal shock stability of clay brick and high alumina brick is good?
High alumina brick is made of superfine alumina, fused corundum and fused mullite as main refractory materials.
Q: High alumina brick 80 with which high aluminum cement?
Which kind should be chosen should be determined according to the conditions of use, life expectancy and cost control. By the way, the quality of masonry is also very influential.
