Product Description:

Features: use temperature of 1400 DEG C, has good thermal stability, thermal shock performance is better than the ordinary refractory material and recrystallization of SiC, antioxidant, acid and alkali resistance, wear resistance, and has higher flexural strength. In the aluminum (Al), lead (Pb), zinc (Zn), copper (Cu) as the molten metal corrosion resistance, erosion resistance, no pollution.

  Pipe.

  1, the lift tube, aluminium wheel hub for industry, low expansion coefficient and good thermal shock resistance and strong corrosion resistance, good thermal shock resistance, thermal.

  2, the crucible heating sets, for aluminum liquid, it has good thermal conductivity, corrosion resistance, long life.

  3, the raceway tube, used for ground brick furnace, diameter 30-50mm, length less than 1500mm, high temperature resistance, no deformation, high strength.

Q:How much is the bending temperature aluminum silicon carbide brick for torpedo car
High alumina brick is made of superfine alumina, fused corundum and fused mullite as main refractory materials.
Q:How many cubic bricks does a high alumina brick have?
It is related to the content of aluminum in high alumina bricks.
Q:What are the requirements for Rubble backfill height?
1, filling thickness is not greater than 50cm.2, filling, the use of layered filling.
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
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:What kind of material is the general metal case?
We usually discuss the electromagnetic radiation of computer enclosures, mainly RF radiation, followed by MF leakage.Switch signal of RF radiation from computer high-speed leakage, such as one of the energy radiation is CPU frequency, graphics, display output line, keyboard, is the source of the operating characteristics of the computer leaked out, is also the main part of computer security.For the absorption of radio frequency radiation, the best is the use of copper materials, the use of other metals can also, thickness enough on the line.The most vulgar description is that people can sit in the case is a good thing.
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:How to reduce porosity of high alumina brick
In order to reduce the porosity of high alumina brick, the corresponding measures should be taken from the selection of raw materials, batching, mixing, molding and firing.The water absorption rate of the first grade high alumina bauxite clinker should be less than 5%, and the water absorption rate of two grade high alumina material should be less than 7%. Fine grinding of soft clay and bauxite clinker with less than 4% water content. Mixed fine milling ingredients with this, can reduce the porosity of bricks.
Q:How to make refractory bricks and boiler wall adhesion more firm?
Suggest that you use fire brick to increase the length of brick or pull the amount of turn, and use high temperature mortar masonry
Q:Can high alumina brick resist carburizing?
The resistance to carburization is not directly related to the bulk density of bricks
