Product Description:

Dead-burned magnesite is selected from natural magnesite, calcined temperature and the shaft kiln. It is the material of ordinary magnesia bricks, shaped and unshaped refractory products.
Specification

Application

 It is used for steelmaking furnace bottom and ramming furnace.It is made from high quality magnesia and high purity magnesia-dolomite clinker in appropriate granularity ratio, it has good sticking ability, low rebounding rate and high abrasion-resistance
Usually it is used for converter gunning repairs

Q:how about the performance of aluminum silicate fire proof thermal insulation?
aluminum silicate refractory fiber board has following characteristics:1. the structure is more even than natural wood. it avoids rot, moth-eaten and other problems, 2. fiber board has small expansion and contraction, which is easy to be processed. 3. its smooth surface is easy to paste a variety of finishings and you can make furniture more beautiful. Decorative wood-based panel is to embellish their homes. I hope it is useful to you!
Q:Fire rating of decoration materials
You can refer to (code for fire protection design of buildings)
Q:Which plant need to make refractory mould?
Q:What kind of materials can be tested their electrical resistivity in the current refractory industry?
Graphite, Magnesium Oxide, and alumina are all feasible.
Q:What is required to do refractory material?
Can you be more specific about what aspect?
Q:What antioxidant will be used in refractories?
Antioxidant: Si, Al, Mg, Ti, AlSi, AlMg, SiC, TiC, ZrC and these metal nitride, boride. Sintering agent: different mechanism, Cr2O3 to promote the sintering of alumina;CaO/MgO style promote ZrO sintering;Siliceous ramming material to add boron bottles, magnesia coating and clay, etc.
Q:What is the limit of fireproof rolling shutter?
According to the national standard 14102-2005 GB standard, the provisions of 14102-2005 GB specify that: According to provision 14102-2005 GB: If fire resistance limit of fire resisting shutter is no less than 3 hours, it is AAA fireproof rolling shutter. Therefore, the fire resistance limit of AAA grade fireproof rolling shutter should be 3 hours.
Q:Which kind of refractory does insulation board belong to ?
Q:Which kind of external wall fire barrier zone material is better?
I recommended foam cement and particulate thermal insulation composite waterproof material, which is fire isolation area product, which uses surface of vertical plate arranged fiber technology to make the compressive strength in the vertical direction up to above 80KPa. At the same time, under the conditions of both exterior heat insulation and effects of humiture in the long-term, it can still maintain the non-aging performance of various aspects, and safety (reliability), fire resistance and excellent durability.
Q:What are included in fireproofing materials?
Incombustible material of construction fire-proof material Grade A: Cement, stone, steel, coat, glass, aluminium alloy, ceramic tile, etc.; nonflammable material Grade B1: Fireproof panel, rock wool.
