- Q: how to distinguish the quality of high alumina refractory brick when you buy it ?
- see the gap between the bricks and between kiln roof and kiln wall, etc.. 6, the pressure and the volume density of Pei brick and brick Pei size, appropreate matching of high alumina powder and high aluminous aggregate and other materials, the drying and time, and the mud trapped material humidity 1. 7, to reach the requirements of production. 4, the order of loading Pei brick into kiln . should prevent the lack of a scene , the requirement , mixing time, different procedure and the order of the adding of raw materials of high alumina brick. 3, drawing plan and lack of edge of high alumina brick . 5
- Q: what is consequence of high load and soft low of high alumina refractory brick ?
- softening, if not up to the design requirements, may cause vicious incident like the collapse of the stove in use. the full name is softening temperature under a fixed load, as the name suggests, it is the softening temperature after adding the load.
- Q: Is fireclay brick acidproof? Does clay brick anti corrosion when it's used to build chimney lining?
- Refractory bricks anti acid and alkali after high-temperature calcination, and anti-corrosion won't be a problem
- Q: What is the problem about splintering when the refractory brick is fired?
- There are many bubbles inside the refractory brick, it is also possible that the brick itself is not up to the standard about volume density, then refractory brick fragmentates. There are many reasons, may be in the process of repression
- Q: What is the sintering of non clay bricks?
- Many kinds of brick, according to the raw materials used for clay brick, shale, coal gangue brick, fly ash brick, lime sand bricks and slag brick; according to the production process can be divided into sintered brick and non sintered brick, which can be divided into non sintered brick brick, autoclaved bricks and autoclaved brick etc.; according to whether the holes can be divided into ordinary bricks, porous brick, hollow brick.
- Q: T38 size of high alumina refractory brick
- high alumina brick, according to the aluminum content, is divided into four grades, the aluminum content of the first grade is no less than 75%, also called the special high alumina brick; the aluminum content of the second grade is no less than 65%, the third grade is no less than 55%; the aluminum content of super high aluminium brick is more than 85%; If the shape is very irregular, it is usually called the super special high alumina brick. in short, there is a universal type of high alumina brick except for standard high alumina brick, customised according to the specific appliction of the kiln.
- Q: what kind of refractory brick is suitable for 1300 degrees converter?
- The furnace cap tapping shaft part should use MgO-C brick with high slag resistance and thermal shock resistance, the steel side can be slightly thin, bottom carbon content may be appropriate less.
- Q: Whether fireclay raw materials or clinker are used when masonrying general fireclay?brick? What is the difference between raw material and clinker?
- Generally, refractory bricks use clay refractory mortar, raw material and clinker are halves
- Q: How good is the hardness of corundum refractory brick?
- The basic materials of corundum refractories are fused corundum or sintered corundum. the refractory brick containing more than 90% of Al2O3 is called corundum refractory brick. so, corundum refractory brick. Corundum has a high hardness (9 level of Mohs hardness) such as zirconium corundum refractory brick. Corundum refractory brick is resistant to acid well and melting point is also high, also known as pure alumina refractory brick products, , it has a good effect. These are closely related with the structure of the Al - 0 key, titanium corundum refractory brick, and other basic slag. It is used in high temperature oxidizing atmosphere or in reducing atmosphere. the metal and glass solution have good stability. a-Al2O3 is the main material of high temperature refractory brick and high temperature electrical insulating material .
- Q: What material is good of refractory bricks?
- It can also be divided into a variety of kinds, it mainly depends on where it is used, each has its own advantages, neutral three categories of refractory bricks have a variety of materials
