- Q: The stove which made of refractory bricks and fireclays will produce cracks after being used. How to solve this problem?
- The use of low expansion materials will be better. But as for the stove, the appearance of crack is attributed to the selected materials or the environment. And when the temperature is not high, there still seems to be crack, so through expansion joint reservation, not allowing itself to crack
- Q: What is the role of refractory brick, whether is there any books to introduce refractory bricks
- Refractory bricks are generally used to build a hearth. Such as, boiler, furnace (molten metal), air heating furnace etc, the furnace need refractory bricks to bulid.
- Q: Lining of refractory bricks in rotary furnace
- The lining of the converter is probably a furnace, but if it is changed at least to see the material and the use of it. There are a lot of damage to the lining, such as: The total impurity content reduces to 2%, lining life will increase 20%-40%; CAO in brick is of 60%-80% content , lining life are the highest; also some other proper index can not be ignored such as bulk density,heat/thermal shock resistant performance,porosity,thermal expansion,fracture resistace,volume stability,Slag resistance,and so on. In addition, lining erosion rate is the largest when the basicity of slag is 1, with the increase of basicity, erosion rate decrease rapidly, the temperature can cause cracks spalling of lining. At the same time, the building process is also very important.
- Q: Clay brick, red brick, always fried brick how to do?
- Red brick fired, try using a bubble, if not burst, you can use.
- Q: Are there any good improvement measures for the always collapse of the previous vaulted tunnel kiln built by refractory bricks?
- Volume shrinkage, uneven shrinkage and expansion of part, long-term high-temperature processing crystal type changes, calcium and other substances forming the refractory brick is Magnesium Oxide. Also the temperature changes quickly, and belongs to the crystal compound, silicon aluminum, sealing material's selection should be pay attention to
- Q: does the furnace wall use refractory bricks to keep the heat? Or use the insulation material to keep heat ?
- The furnace arch and the furnace wall are all refractory bricks, and the refractory brick is a kind of thermal insulation material!
- Q: What building materials can take the place of clay bricks?
- Are aging fast, can greatly save the time, from the practical results, the red brick walls every day only skilled workers built about 2.5 cubic meters, while the foam concrete block can be built about 6 cubic meters per day, calculated by 50 yuan per person per day, only a fee per cubic wall can save nearly 16 yuan.
- Q: Are refractory bricks poisonous?
- Zirconium minerals are often associated with other minerals in the mining, because the bricks are basically burned under more than 1 thousand degree. But some of the bricks contain heavy metal elements chromium. Some of the brick contains zirconium, the vast majority are very safe, and heavy metal elements have a certain toxicity, there are many kinds of refractory bricks that the nature is very stable, and the associated minerals are generally radioactive
- Q: How to use the winding packaging machine to pack refractory bricks
- Over 150KG the most common winding machine can pack, if it is light or the goods scatter, then add capping or pre-drawn device is all right.
- Q: Can refractory bricks be used to build a house?
- Refractory brick can be used to build houses, but you can not use ordinary cement to build, the cost is 3 times than that of ordinary brick.
