- Q:what needs to be noted when choosing and using blast furnace fireproof materials?
- it depends on the size of the blast furnace. below 200 cubic meters alumina bricks and carbon brickcan be used. 200 cubic meters and above are currently integrated bottom, not the same as the size of the cubic level, varying in the use of refactory. I hope my answers above are helpful to you and your ideal anwers.
- Q:what is the common materials for home fireproofing material?
- 1, lumber core 2,decoration panel 3 , plywood 4 density board 5,chipboard 6 fireproof?panel, 7.gypsum board Hope to adopt my opinion
- Q:which kind of refractory is used in golden smelting furnace? How about his using temperature
- generally the price of the quartz sand refractory material is higher and the temperature can meet the requirement of 2000 degree.
- Q:What are the meanings of azs, 34% and ec in fused brick?
- The fused brick, also called zircon corundum brick, is shorted as AZS for three chemical components in Al2O3-ZrO2-SiO2 ternary diagram. I don't know the meaning of EC.
- Q:How to count the construction costs of refractories?
- In winter, the temperature of the the fire-resistant masonry, fire-resistant plastic, sodium silicate, phosphoric?acid castable should be maintained above 5 ℃. Usually greenhouses in which heating facilities are installed to maintain the appropriate temperaturere for the construction environment should be erected in refractory masonry. The temperature around the construction site of the industrial furnace and refractory masonry shall not be lower than 5 ℃.
- Q:Is it normal for caable fire resistant material to catch on fire?
- Abnormal; aging is certainly one of the cause of the fire. That is caused only because of poor insulation and aging caused by short circuit, but a more important reason is configuration of air switch does not meet the requirements. If the capacity of air switch equals that of the cable, trip will happen at the moment when current is overloaded, not causing a short circuit or over current fire.
- Q:How to distinguish between class A fire resistant door and class B fire resistant door from appearance ? What are the differences between the two refractories? Thank you !
- First, the materials are the same. But the thickness of grade A and grade B fire doors is different juding from their appearances. Grade A :50. Grade B:45. Added question: Do you refer to steel fire door?
- Q:What refractories are accessible with ease in daily life?
- Basically there have all materials. But it depends on your needs.
- Q:How is the performance of refractory materials?
- It is a little difficult to answer. There are some requirement for refractory materials, such as fire resistance, softness, creep, thermal shock, abrasive resistance. Besides, requirements for construction performance include: Liquidity, plasticity and other linear change rate, volume density, strength (including high temperature) and all other important indicators must be tested the same conditions with the use of test conditions and test items like body density, strength, line changes in the basic project
- Q:Does anyone know the fire endurance of steel stud partition?
- Indeed ① Dragon Brand gypsum board fire-resistant partition: Its fireproofing extreme time is 4 hours, suitable for firewalls of a variety of public buildings, public exit passageway and other partitions, which meets the first level of fire protection standard ② fireproofing and pressure-resistant partition: Refers to the partition which can withstand momentary gas shocks of over 1200pa , mianly used for the room partition with inert gas fire-fighting needs, such as equipment rooms. The pressure-resistant degree of fireproofing and pressure-resistant partition of Beixin Building Materials can be up to 4800Pa, especially suitable for high-rise fireproofing.
