Q: What are the fire endurance requirements of class A fire resistant door ?: Fire endurance of class A fire resistant door is 1.5h. According to the latest fire door requirements, in FMA FMB FMC three forms, A, B and C represent categories, such as FMA on behalf of Class A fire doors (ie thermal insulation fireproof door). Fire endurances of class A,B and C fire doors are 0.5 1.0 1.5 2.0 3.0. Therefore, the fire resistance of fire door needs to be designed and the design paper will make it clear in general.

Q: Where is the production of refractory manganese alloy manufacturers? Manganese is recommended between 63 and 70!: China is mainly used in honing, maybe I face all doubt you forget who may waste cheap no taste who cheated you don't mind set back easily stripped of a planet in the comfort of your brow you open your mouth and then grow the universe to my hand behind you let you spend what a fragile Oh maybe I face all abandoned about half past three in the morning wake up to drink a cup of soda rather baffling weary belch a bubble the tiny uneasy, and perhaps two of us Butterfly

Q: Who knows how to divide the building fire grade and fire resistance grade?: I hope to help you building fireproof rank division is one of the most basic measure in building fire safety technical measures, Building's fireproof rank is divided into class one, two, three, four according to China's architectural design specification. Fire-resistant capability of the highest level is the strongest; Fire resistance of four level of the weakest. The fire resistance level of a building depends on the combustion performance and fire resistance of the building components that comprise the building. The so-called building component refers to a series of basic components, such as wall, foundation, beam, column, floor, stair, ceiling and so on.

Q: What's the definition of fire endurance of the fire-resistant coating for steel structure?: 1. Fire endurance. Conduct fire resistance test of any building component according to the standard time-temperature curve, and the time when it is subjected to the fire to the time when it loses support capability or fire insulation function or its integrality is destroyed is referred to fire endurance. 2. Steel has relatively low fire endurance which is usually 0.25h only, namely 15 minutes; 3. Of steel structure buildings, steel can be used as beams, pillars, etc. but its fire endurance is not enough (usually these components have higher requirement on fire endurance, and take pillar as an example, it is usually demanded that the fire endurance should be 2-3h), and under this condition, it needs to brush fire retardant coating so as to raise the fire endurance. As to the specific quantity or types of the fire retardant coating, it is decided upon the actual conditions. In short, the building material needs to meet the required fire endurance of the buildings.

Q: How much is the duration of fire resistance of the porous brick shale?: The duration of fire resistance of the porous brick shale could reach 1,580℃—1,770℃. It is predominantly applied in coke oven masonry and building, glasses, porcelains, carbon calciner, and the vault of thermal furnuces of refractory bricks as well as other load-bearing elements, and high temperature bearing parts of cowper stove. But it should be aware that it can’t be used in thermal equipment below 600℃ and with large variation of temperature.

Q: Can I use ordinary cement with the addition of sand, clay, and salt as refractory material to paste the stove?: Add some hair and slags, or it will crack before calcination.

Q: Does the refractory material used in steelmaking all refer to refractory brick?: For example, refractory castable doesn't only refer to refractory brick, but also some bulk material and ramming?mass. Desulfurizer belongs to ferrous metallurgy auxiliary material.

Q: I would like to know if there is any requirement for refractories in the crucible type high-frequency smelting furnace Worry！ I hope you can help me! This time!: High enough for high temperature resistance. Refractory materials for crucibles shall be subjected to a high temperature greater than 1700 DEG C and the softening temperature shall be greater than 1650 DEG c;

Q: How to deiron refractory?: It cannot be done in conventional approaches, because you are referring to refractories. If using acid liquor soaking method to deiron, the material itself will be also damaged! If just for reducing the corrosion of materials, it will be OK to add a corrosion-resistant and fireproof protection layer.

Q: What are the requirements for the performance of refractory materials?: Electric furnace bottom and furnace slope and the wield pool should be magnesia whole knotting, magnesia carbon brick and tar magnesia brick; hot and slag line area, using high-quality magnesia-carbon brick; Brick on both sides of the furnance door should be tapping El magnesia brick, magnesite chrome brick; electric furnace cover should be high alumina brick and high alumina bricks.
