What is fused magnesite?
Fused magnesite is produced by high quality magnesite through electro- fusing, After melting, the SiO2 of material moves to the surface for the difference in the specific, so it has well grown crystals, well crystal perfection and structure homogeneity, excellent chemical stability, good corrosion resistance to slag and high strength at high temperature.
Where to apply fused magnesite?
It is widely used for gunning materials, fused magnesite ramming material, magnesite brick, magnesite chrome brick, vacuum and vacuum induction furnace, electric arc furnace refractory lining, magnesia crucible, furnace and a variety of refractory, such as large scale glass furnace by floating method, electrical furnace, convert furnace, house hold electrical appliances as electrical insulating materials,
- Q: Where is the production of refractory manganese alloy manufacturers? Manganese is recommended between 63 and 70!
- The cut is relatively transparent if you jam, we have also used silicon manganese alloy
- Q: What problems should be paid attention to while using refractory materials under a controlled atmosphere?
- Pay attention to the performance of the materials, and the use of non oxide materials!
- Q: What are included in wall fireproofing material?
- External wall thermal insulation materials are divided into A and B according to combustion level. Grade A is incombustible material, while grade B is combustible material. A few years ago, fires in CCTV building and Shenyang hotel resulted from grade B material. Currently grade A is usually used, and some are even cheaper than the grade B material. Grade A is roughly divided into insulation mortar, phenolic board, rock wool board, foam cement board, etc. Insulation mortar is quite good. It is easy and convenient to construct, has low cost, but the production is too simple and it is easy to fake.
- Q: Is the linear change on reheating the same as heating permanent linear change of refractory material?
- “+”represents expansion. the afterexpansion and aftercontraction after cooled to be at room temperature. The change may significantly damage the masonry of thermal kiln. There are regulations on the linear change on reheating of common refractory material in the national standard. Some physical chemical changes may continue. It is defined as the change from being heated to the specified temperature of refractory material sample. Heat preserving for a while till afte cooling to be at room temperature, then the residual will expand or contract in its length, heat preservation for a while, organization vitrification, the irreversible changes of its length refers to heating the firing refractory to be at high temperature, so as to make the volume of refractory materials expand or contract, due to the influence of uneven temperature or lack of time, otherwise it will cause the deformation of the refractory ball and make this indicator within standard even reach smaller value, so firing control must be strengthened in product production. But it is should not be too high. For refractory materials with same chemical composition, the linear change on reheating is produced in the heating process. Properly increasing sintering temperature and prolonging the holding time is an effective process measures, make its firing inadequate. When subjected to high temperature, it can reduce the thermal shock resistance. Minus sign "-" represents contraction. The permanent line rate refers to heating the fire refractory ball to the specified temperature. Linear change on reheating, also known as residual linear change, is an important indicator to assess the quality of refractory in the long time use. To control the permanent line rate within the standard or reach the minimum value.
- Q: Who knows about the fire endurance of grade C fire doors?
- It can be classified according to the fire endurance and thermal insulation performance: The fire endurance of grade A fire doors is not less than 1.5 hours; that of grade B fire doors is not less than 1.0 hours; and that of grade C fire doors is not less than 0.5 hours. I hope my answer can help you.
- Q: How many fire endurance grades are the AAA fire resisting shutter divided?
- According to the fire endurance, the fire doors can be divided into Class A, Class B and Class C fire doors with the fire resistances are not less than 1.20h, 0.90h and 0.60h. Even the fire resistant level of B can also use the first rate fire resistant door.
- Q: what is the material of fixed first rate fire resistant window?
- Window frames and fireproofing glass, fire sealing strip, fireproofing glass mound layer, which is infexible fan, and the flexible fans have to plus folding and closing window cleaner. (3) window frames must be integral with the building, using wood or iron to connect the wall. After the installation of the steel frame, the cement mortar must be watered between the window frame and the wall, and it should conserve more than 24 hours before normal use.
- Q: how long is the fire endurance of plasterboard?
- Plasterboard is non-flammable B1 level products. There are introductions in Fireproof Specification of National Standard Building Interior Decoration Design. Plaster board mounted on steel stud can be used as A level decoration materials. In accordance with the national fire safety rules on fire durance of walls and ceilings and other components, we can not simply say whether a piece of gypsum board can meet the requirements. In GB "gypsum board" it clearly states: Fireproof plasterboard can endure fire longer than 20minutes. Wherein Dragon brand fire-resistant gypsum board can endure fire longer than 40 mintues. Gypsum board is comprised of dry wall, steel stud and various auxiliary materials. the fireproof performance of the gypsum board system is relevant to the type, quality , layers of the gypsum board, quality of keel and installations, whether the rock wool is filled and its unit weight, the treatment of seaming and some minor joints.
- Q: Pals who know something about fire resistant material please tell me how many types of refractory material there are
- Refractory materials used in special applications include high temperature oxcide, such as alumina, lanthanum oxide, beryllium oxide, calcium oxide, zirconia and other, refractory compounds, such as carbides, nitrides, borides, silicides and sulfides; high temperature composite materials, mainly contain metal ceramic, high temperature inorganic coatings and fiber reinforced ceramics.
- Q: What are the additives and recipes of refractory?
- SM water reducing agent
