- Q: What's the reason of cracks in refractory bricks?
- The relative density is high, and high temperature heat treatment and increase the strength of qualitative brick, for 10 days, then only the shorter time for heating and drying and dehydrating, you can smash a brick if it's a long time! There will be a stress loose phenomenon making bricks now, the internal density of these crack bricks are not the same, in addition to the effective drying, dehydrating and heating treatment, the time distance is small, basic bricks and finished bricks adopt line production, when drying, the water is also evaporated at the same time, the central density should be high ! The reason is very simple, the greater extrusion force the brick bears in the molding, the closer to the edge, the smaller density is, the better to keep forming, the shorter residence time, the higher the rate of finished product is, which belongs to the natural drying, this phenomenon is more obvious
- Q: Which thermal stability of clay bricks and high alumina bricks is good?
- Thermal shock stability is much better than clay brick.
- Q: Are sintered brick concrete bricks?
- Sintered brick: brick made of clay, shale, coal gangue or fly ash, made by molding and roasting at high temperature. Bricks used for masonry, load-bearing and non load bearing walls are collectively called sintered bricks.According to the raw materials, they are divided into sintered clay brick, sintered fly ash brick, sintered coal brick and so on.A sintered brick with a solid or void ratio of less than 25% is called a sintered ordinary brick.The production and use of ordinary clay brick has been in China for more than 3000 years. Nowadays, ordinary clay bricks still dominate the wall materials used in construction projects. Although the ordinary clay brick has many disadvantages, due to its low cost, simple process, design and construction technology is mature and people's inertia and other reasons, the ordinary clay brick for quite a long period of time, especially in rural areas, is still one of the main wall materials.
- Q: Can refractory be used to sharpen knife?
- Many factories build a smelting furnace by using this kind of bricks. A special knife grinder can be used to sharpen knife, can on 1. They are sizing and non-sizing refractory bricks respectively. Refractory brick is now a lot of fields and industry will introduce one of the raw materials. Products are divided into two different types, refractory brick as a high temperature resistance of the raw materials. In simple terms, working temperature is 770 DEG C, 580 C and 1, of course, refractory bricks also can be used to sharpen knife, use smooth brick to sharpen, need to choose high hardness
- Q: Can red bricks be burned in tunnel kiln which used to burn refractory brick?
- Of course. But the temperature to burn refractory brick is very high, the average temperature is above 1500 degrees. And the temperature to burn brick is not so high, about 1200 degrees. So you should control the temperature, the tunnel kiln to burn firebrick and the tunnel kiln to burn red brick are the same, there is just a little bit difference in the materials used to build the stove!
- Q: What raw materials can be added to fireclay brick to respond to the urgent cold and urgent heat?
- The effect of adding andalusite is better
- Q: With what three clay brick clay brick with six holes under what circumstances?
- Different specifications, different strength, and use in different structures.
- Q: can castable refractory replace refractory bricks in rotary?kiln?
- The heat produced in the welding process will cause local deformation of the rotary kiln, which will affect the dynamic balance, and the construction difficulty in the middle position of the rotary kiln is much larger than that of the refractory bricks. Moreover, the construction quality is not easy to ensure, generally only replace the refractory brick in the kilneye, because the construction of the castable refractory need to weld the anchor
- Q: What is the main use of refractory brick?
- Almost all high temperature furnace needs of the needs refractory bricks, such as blast furnace for iron smelting, high temperature differential thermal analyzer also use it, refining furnace, converter for steelmaking, muffle furnace, electric furnace and drying equipment. the uses are wide
- Q: does Kyrgyzstan have the refractory brick to build tunnel kiln, whose specifications are 390,235,11, 240,120,60.
- Domestic standard brick has no brick in this specification. only can be customised. Otherwise only have 230 * 65 * 114.
