Product Description
hot sale high temperature resistant refractory firebrick for metallurgy
Fire clay bricks were mainly made from chamotte, flint clay and combining clay powder, being high pressure pressed and sintered in high temperature.
Low porosity bricks are made from low mullite stones, the main mineral composition of the low mullite stones are pressed and sintered mullite phases. The bricks have very good physical and chemical properties in high temperature conditions.
Different Size Fire Clay Brick Features and advantages:
1.High refractoriness,
2.High-temperature endurable.
3.Good corrosion resistance.
4.Good spalling resistance and wear resistance.
5.Good thermal shock resistance.
6.High mechanical strength.
7.High-temperature creep rate is low.
8.Good volume stability at high temperature.
hot sale high temperature resistant refractory firebrick for metallurgy application:
They are were widely used in all parts of furnace lining for middle and small capacity furnace such as glass furnace, blast furnace, hot-air furnace, cement furnace,chemical furnace and other heating engineering equipment.

- Q: What are the reasons for the spalling of refractory bricks in the production of lime kiln?
- In the course of the production of lime kiln, the local block of refractory brick is a very dangerous signal. It is suggested that you stop the kiln to prevent the collapse of a large area. Lime kiln is the main equipment for the production of limestone kiln and rotary kiln is two, with the growth of calcium carbide lime kiln industry, iron and steel industry, the construction industry to the amount of limestone has become the main production equipment, and refractory bricks became the heart of lime kiln.
- Q: How much is one ton of high alumina refractory brick?
- Three high aluminum refractory brick Zhengzhou Kuwait is generally around 800. 32 years of experience, good.
- Q: What are the requirements for Rubble backfill height?
- Backfill should be filled with large stones, big face, small face upward, the decoration is stable, and then use small stones leveling, the gap between the stones can be swept into the slag, gravel, so that the gap filled.
- Q: What is the standard size of high alumina brick?
- The country has laid down a number of criteria for the use of refractory bricks to unify market demand.
- 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: What is the density of a super high alumina brick and what is the price?
- Of course, the transaction price, please choose refractory brick manufacturer is better.
- Q: What kinds of minerals are there in the five major categories of ore crystal chemistry?
- Halide. A few species, about 120 species, accounting for only 0.1% of the earth's crust. Most of them formed in the surface conditions, forming a salt mineral, containing less pigment ions, light color, low hardness, generally less than 3.5. Common mineral halite (NaCl), potassium (KCl), fluorite (CaF2) etc..
- Q: What is spalling resistant high alumina brick?
- Using bauxite as main raw materials, the introduction of a small amount of ZrO2 (ZrO2 is due to phase transition, between monoclinic and tetragonal type can improve the thermal stability of the products), adding a certain amount of binder and additives, the particle size distribution control mud, forming and sintering of refractory products produced, called anti stripping high alumina brick.
- Q: Does the chimney have high acid resistance?
- If it is an ordinary high alumina brick, it does not meet the requirements of acid resistance, and only the chimney lined with acid resistant bricks.
- Q: Which thermal shock stability of clay brick and high alumina brick is good?
- The product has the advantages of high temperature, little creep, strong corrosion resistance and good thermal shock resistance, and is suitable for large and medium-sized hot blast stoves.Thermal shock stability is much better than clay brick.
