- Q: How to distinguish between sintered clay brick and sintered coal gangue brick
- Two kinds of brick color is not the same, the red clay brick, the brick surface slightly dark, in addition there are also differences between the surface of brick also has the difference between the former than the latter.
- Q: How to repair the boiler?
- use refractory bricks and plastic refractory
- Q: What types of refractory bricks are divided into?
- Chimney and flue are places that high temperature gas of sulfur gathers, it should use acid material. Refractory material is divided into three major parts: acid, neutral and alkaline.
- Q: Refractory brick, high alumina brick, magnesia chrome brick, magnesia brick, clay brick, which type of brick has the highest refractory temperature?
- It depends. if high alumina brick is used in kiln, its temperature is above 1700 degree, clay brick is between 1500 degree to 1750 degree, magnesia bricks and magnesia-chrome bricks are about 1500 degree to 1650 degree.
- Q: What are the ingredients of brick?
- Artificial small bulk building, divided brick (clay brick) and non sintered brick (sand lime brick, fly ash brick etc.), commonly known as brick. Clay to clay (including shale, coal gangue powder) as the main raw material, through mud processing, molding, drying and roasting and. Chinese in the spring and Autumn period has created a square and brick, Qin and Han Dynasties brick technology and production scale, quality and variety have significant development, known as "Qin Zhuanhan tile".
- Q: Is the waste of the fire resistant hazardous waste?
- it mainly depends on whether the refractory bricks contain chromium, if not, we only need to properly dispose of them, it would cost less and assure that there is no bad effect on people and the environment, shoot two hawks with one arrow; if there is hazardous elements like chromium and mercury, it may cost much and be disposed as industrial waste(or construction waste) by local environmental protection department, it is ok if there is a large amount of waste, because the environmental protection department will not take those waste that is not obviously dangerous seriously, even if it is dangerous waste. If there is no suitable manufacturers. It is better to look for a refractory brick manufacturers to recycle it, the cost is acceptable if the amount is small. In general, these heavy metal containing refractory bricks need to be disposed by the company that has quality to dispose such hazardous waste.
- Q: how to test the high alumina refractory brick mixed alumina?
- The first thing before producing bricks is to test whether the aluminum content reaches the standards, general testing on raw materials. Second: the shaped high aluminum brick will be tested in some professional equipment, you can know it from the professional inspection departments.
- Q: What can be applied to the burned refractory brick to resist heat shock?
- Acidic refractory material use monox as the main component, among which cilica brick and clay brick are commonly used. Silica brick is silicious product containing monox more than 93%, whose raw materials include silica, waste silica brick scrap and etc. The acid resistance of slag erosion ability is good, and the softening temperature under a fixed load is high. The volume won't shrink after repeated burning, but even a slight expand; but it is vulnerable to the erosion of basic slag, and has low thermal shock resistance. The silica brick is mainly used for coke oven, glass melting furnace, acid hearth furnace and other thermal equipments. Clay brick uses refractory clay as the main raw material, containing 30% to 46% of aluminuum oxide, belong to weakly acidic refractories. It has good heat shock resistance and corrosion stability to acid slag, and it's widely used. Neutral refractory materials use aluminum oxides, chromium hemitrioxides or carbons as the main components. Corundum products containing more than 95% of alumina is a kind of high quality refractory material with wide application.
- Q: What are the factors that determine the weight of the refractory bricks?
- (5) Under high temperature, the volume is stable, the inner part of brick will produce unrecoverable volume shrinkage or expansion because of the internal transformation. Therefore, masonry inner will produce stress to make the material break and peel off, and the weight of a ton of bricks is determined by the bulk density and quantity, how much is the weight of refractory bricks, refractory bricks should have the ability to resist the damage, the weight of a piece of brick is determined by the bulk density: Refractory bricks are used under high temperature for a long term: Refractory bricks in the use of the process. Cooltech refractory brick used in various high-temperature equipment: The temperature of some parts of metallurgical furnace and other industrial furnace is uneven due to rapid temperature change during operation. (3) good thermal stability: Refractory bricks should not only have a high fusion temperature, no softening deformation and collapse, causing damage to the masonry. (4) strong resistance to slag: Modern metallurgy and the other industrial furnace heating temperature is generally between l000~1800. Refractory bricks should have the performance that is not easy to melt under high temperature. Therefore. Therefore, it is subject to high temperature conditions of physical and chemical corrosion and mechanical damage, the refractory brick must have the ability to resist high temperature chemical corrosion, the volume of refractory brick is required to be stable under high temperature. (2) High-temperature structural strength, chemical corrosion of metal, but also should have been built in the stove brickwork load or other mechanical vibration, often has the high temperature slag, so the refractory materials performance should meet the following requirements: (1) high refractoriness
