- Q: Why is the house made of refractory bricks not warm in winter
- Heating equipment can be used
- Q: Lining of refractory bricks in rotary furnace
- The lining now is built with MgO-C brick, the specific time to change it mainly to see the quality and usage of MgO-C brick. A few years ago, the mills are desperately seeking furnace age, some can use thirty thousand furnace, by the way, furnace age of converter refers to the number of steelmaking furnace not time. So now most mills are not simply pursuit furnace age, but economic furnace age, currently furnace age of steel mills around us is mostly in about ten thousand to twenty thousand. In general, the furnace service of the converter is arranged with the overhaul of other equipment. This can realize the synchronous maintenance of various equipment. If the stove is too old but the maintenance is not timely, also is not to replace the lining brick timely, there will be leakage, then the furnace shell and even ring will be damaged, consequences are more serious . The reason is very simple for brick falling off. One is the poor quality of furnace brick,causing brick lining loose, rocking furnace will lead lining brick falling. the other one is the furnace lining brick is pressed too tight in the use procedure and the brick is too thin.
- Q: What are the weak points of clay bricks?
- Clay bricks are clay products with Al2O3 content of 30%~40% aluminum silicate material. Clay brick is made of 50% soft clay and 50% hard clay clinker, according to the requirements of a certain particle size. After molding and drying, the clay brick is burnt at high temperature 1300~1400 degrees celsius. The mineral composition of clay brick is mainly kaolinite (Al2O3, 2SiO2, 2H2O) and 6%~7% impurities (potassium, sodium, calcium, titanium, iron oxides). The sintering process of clay brick is mainly the process of the continuous dehydration of kaolinite and the formation of crystallization of mullite (3Al2O3. 2SiO2).
- Q: Does circulating fluidized bed boiler's furnace wall use refractory to have thermal insulation?
- Heat insulation cotton is laid behind refractory brick.
- Q: Shale brick and clay brick? Answer before you know it
- Has the advantages of high strength, thermal insulation, heat insulation, sound insulation and other characteristics, in order to shale as the main building materials brick construction, is the biggest advantage of shale brick and clay brick traditional construction method is exactly the same, without any additional special ` construction facilities, special tools, is the best substitute for traditional clay solid brick.
- Q: What are the advantages and disadvantages of clay refractory bricks?
- Clay refractory bricks are clay products with Al2O3 content of 30%~40% aluminum silicate material. Solid clay refractory bricks are one of the oldest building materials in the world. They are from the Mausoleum of the First Qin Emperor in Shaanxi to Beijing and the Ming and Qing Dynasties in the Great Wall. It has inherited the history of architectural civilization of the Chinese nation for thousands of years. So far, it is still a popular building material. Fireclay brick materials, cheap, durable, fireproof, heat insulation, sound insulation, also absorb moisture and other advantages, is widely used in civil engineering.
- Q: What are the sizes and sizes of clay bricks?
- According to the compressive strength (Newton / square millimeter, N/mm2) the size is divided into MU30, MU25, MU20, MU15, MU10, MU7.5, these 6 intensity levels.The bigger the size, the stronger the compressive strength.
- Q: What are the main constituents in non clay brick sintering?
- Sintered clay brick, it is through the mining soil, brick making, modulation, drying, roasting and cooling produced, roasting coal amount is solid sintered clay brick coal blending amount of 20-60%, the amount of coal to ensure product's surface.
- Q: What kinds of annealing furnace refractory bricks there are?
- But the energy saving effect is good, but also can use lightwight heat insulating brick, but the price is higher than that of clay brick
- 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.
