Description of Castable Refractory Materials

Castable for ladle is bagged particle, ash grey. It is used as lining material for ladle with the property of high refractoriness, long service life, reduction of materials and manual operation.

Features of Castable Refractory Materials

Easy to operate: times and labor saving, shorten the work time, reduce work strength of workers.

Superior property: resistant to scour and erosion of molten iron slag, good thermal shock resistance, non-stick of iron slag, tiny linear variation, no cracking, and easy to break up.

Extend service life: high technical content, good property in using.

Long service life: can be used for the number of 800-1200

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. The judgment condition of the fire resistance There are three conditions for components' fire resistance limit to be reached, namely, the fire resistance limit of the building component: Loss of support and integrity; loss of time to fire the role of the time; as long as any of these three conditions is met, it will reach its limit of fire. Hope my answer will help you.
Q:How long is the fire-resistant time of fireproof wooden door?
Wooden thermal insulation fireproof door using flame-retardant timber or flame-retardant timber products to make door frames, skeletons of door leaf, door panels. If the door leaf need to be filled with materials, the filling materials should be fireproof thermal insulation materials which is non-toxic and harmless to human body, and matched fireproof door composed of fireproof hardware. Use doors without age limits.
Q:Does the refractory material used in steelmaking all refer to refractory brick?
Besides refractory brick, it also refers to unshaped refractories like fire clay and castables.
Q:How is refractory material made?
It is made from yellow mud and water.
Q:Does refractory belong to stone, building materials or other?
Refractories belong to organic non-metallic materials.
Q:What brands are the best in the A-level refractory materials?
A-level refractory materials: Dulux, Nippon, Carpoly, Skshu and Smoz. Fireproof boards are the most common materials in the market. There are two are commonly used: one is HPL decorative plastic laminates with advantages of fire- ,moisture-, wearproof and oil resistance as well as easy to wash, besides it has a great variety of colors and types. Another one is glass fiber magnesite fireproof board, the out layer of which is decorative materials while the inner layer is mineral magnesium fireproof materials which can resist a high temperature of 1,500 Celsius degree but it is not a good ornament.
Q:Which one is better, fire-resistant wood or steel?
According to my understanding. This fire-resisting wood is better. Iron birch. The iron birch is three times harder than the oak, twice as hard than ordinary steel. It is the world's hardest wood which is used as a substitute for metal. The Soviet Union have used iron birch for the manufacturing of roller ball, bearings and it is applied in yachts. Iron birch has some wonderful characteristics. Since it has very dense texture, once put in the water it will sink; even if it is soaked in the water for a long time, the inside still remains dry. The iron birch is twice harder than the steel, it doesn't mean that its hrc value is twice of that of the steel. HRC means test load 1471.1N (150KG-F) using a diamond cone head with the point angle of 120 degrees to press. The calculation formula HR= (K-H) /C,K=0.2MM,H is the depth of indentation after releasing the major load. C= 0.002MM, so HRC100 is a limit value, then H is 0, which means that even the diamond will not drill into it. Generally the hardness of bearing steel is about HRC60. Iron birch is the championship among trees in terms of hardness. The bullet hit the wood is like hitting on a thick steel plate and the wood will be motionless. So, it is known as a tree harder than steel. I hope my answer will be helpful to you.
Q:How long is the fire resistant limit for ultra thin fire retardant coating?
There is no detailed stipulation for ultra-thin fire retardant coating, and the thickness of the inside is the fire resistance limit shall reach certain time(at least). In engineering, the thickness of the fire retardant coating is generally determined according to the manufacturer's testing report. We use thin fire retardant coating for steel structure: if the fireproof limit is 2.5 hours. the thickness should be 4.9mm. If fire-resistant limit is 2 hours, the thickness shall be 3.5mm. If the refractory limit is 1.5 hours, the thickness shall be 1.75mm. If the limit is 1.0, the thickness is 1.17mm hope my answer can help you
Q:What refractories are used in various parts of the blast furnace.
Blast furnace from top to bottom has the throat, hearth staves, waist, bosh, hearth and furnace bottom. the specific structure is as follows: The throat is the first to be affected by the impact and abrasion, generally use high-density alumina bricks. the upper and central portion of temperature furnace is only 400 ~ 800 ℃, the area with high alumina bricks and silicate bricks. The lower part of furnace is subject to erosion and dust erosion alkali metal vapor due to high temperatures, it is required in such case to use high quality clay brick,high alumina brick,carborundum brick,corundum brick that is slag resistance and alkali resistance, temperature resustant and wearproof. Furnace bosh temperature reached 1400 ~ 1600 ℃, serverly eroded by slag,vapor, flush. so we use carborundum brick and reaction-bonded silicon carbide brick. Bosh temperature reaching1600 ~ 1650 ℃, using alumina brick, corundum brick or silicon carbide brick. the temperature of Hearth near the upper portion of the outlet zone at 1700 ~ 2000 ℃, use of silicate bricks and corundum castable graphite filler, silicon carbide bricks. In 1450 Silly twitch bottom temperature sealing die of hunger slander bet phoenix astringent preserved Grade ~ 1500 ℃, use of graphite bricks and microporous carbon bricks, now use more corundum brick, corundum mullite brick and synthetic mullite brick. x26lt;P class x3d "share-btn"x26gt;
Q:What things and cement mixed can act as refractory?
Cement acts as cementing material. Itself works by refractory aggregate and stir the refractory material for its gelling refractory aggregate both should be fire-resistant.
