- Q: What's the texture of refractory for the hearth of reverberatory?furnace? ?
- High alumina brick; you can use zircon brick under the temperature above 1700? ;may i use mullite bricks under the temperature from 1400 to 1700? you can use clay brick and heavy corundum brick under the temperature of below 1400 degrees, question closely: what's the usage temperature of reverberatory?furnace? < pre accuse = "qRA" > is there someone use refractory fiber?
- Q: What are the standards of refractory concrete ?
- General requirements (1) All the materials for compounding refractory concrete must meet the design requirements and they should be checked according to the relevant standard. (2) The compounding of refractory concrete should be done strictly in accordance with the compounding proportion (usually weight), and the using of various binders, aggregates, coagulant, and water should be accurately measured. Tolerance of difference of cement, powder and water should be not more than 1 %; weight of aggregates does not exceed 3%. (3) The mix of different varieties of concrete must be prevented. (4) A variety of raw materials should be piled separately according to different species, mark numbers, dates of manufacture. Do not mix with limestone, silica, railroad ballast, dirt and other harmful debris.
- Q: Why does refractory need to add coarse firstly and then add fine aggregate?
- Oh, adding coarse aggregate first is to select good material to make aggregate, and the rest cna be made into fine aggregate. Because if it contains impurities, once being sintered, the appearance will be affected, but fine aggregate does not have this impact.
- Q: What's the heat conductivity coefficient of fire-resistant material?
- There are many types of fire-resistant materials woth different thermal conductivity. The question should be more specific.
- Q: Who knows about ranking rules of fireproofing thermal insulation materials for exterior wall?
- (1) the height of buildings is greater than or equal to 24 m, the combustion performance of thermal insulation material should be A-level. (2) the height of buildings is less than 24 m, the combustion performance of thermal insulation materials should be A- or B1-level. When using B1-level thermal insulation materials, fire barrier zone should be set in each floor. (3) incombustible materials should be used as the protective layer of thermal insulation materials. Thermal insulation materials should be completely covered by protective coatings. The thickness of protective layer should be no less than 3 mm. (4) The base walls should be set in buildings with nontransparent curtain wall structures of metal, stone,etc. The fire endurance of which should comply with relevant provisions of current fire?safety?rules on fire endurance of external wall. The fire endurance and fire protection construction of pier?between?two?windows, window sill walls, skirt walls of glass?curtain?walls should comply with relevant provisions of current fire?safety?rules on building curtain walls. (5) the internal cavity of base walls, as well as the space between the skirt wall and base walls, pier?between?two?windows, window sill walls should be sealed with fire-proof sealing materials at each floor.
- Q: Does anyone know what is the use of waste refractory materials?
- 1.Waste refractory bricks can be reused to make the refractory bricks after being crushed by crusher, but the price is not very high. The purchasing price of refractory plant is ?60/ton. Because the refractory material has been calcinated for two times, it becomes easier to make bricks expansion coefficient with waste refractory bricks, but too much is inadvisable. If too much, the refractory materials would have a bad combination, which will give rise to loose bricks and incomplete corners. Nowadays, ordinary refractory plants would purchase waste refractory bricks to produce bricks, but better plants wouldn’t do this.
- Q: What is the difference between the fire?rating and the fire resistant level of the fire-fighting equipment?
- Fire rating and fire-fighting rating are the misnomer to the building fire resistant level. The building fire risk is measured by fire resistant level. The article 3.2.1 and 5.1.7 of "Architectural design code for fire protection" have made provision respectively on the fire resistant level of plant (the storeroom) and civil construction. Article 3.0.2 of "Code for fire protection design of tall buildings" has made provisions on the fire resistant level of tall buildings. As for the warehouse building "category malonate", it refers to one of the fire risk of goods storage, which is divided into A, B, C, D, E, and each category is refined depending on the nature of different substances. "Malonate class" specified in article 3.1.3 of "building design for fire protection" refers to the flammable solid.
- Q: What are the materials of class A fire resistant window?
- Fixed class A fire resistant window should be made up of steel frame, steel casement, and fireproof glass. Fire windows, made up of steel frame, steel casement, and fireproof glass, refers to window that isolate and stop the fire from spreading. Fire window is named according to the main materials of the frame and casement. Window frame is made up of steel and casement wood, vise versa. I hope it is useful.
- Q: Can anyone tell me what is a high alumina refractory?
- High alumina refractories: High-alumina refractory products have high refractoriness, compressive strength and refractoriness under load, which are used for building the high-temperature parts of various large blast furnaces, such steelmaking furnace, airheater, electric furnace, rotary?kiln and other thermal equipment.
- Q: Fefractory of aluminium oxide.
- Do you mean the alumina hollow ball brick? We can exchange private messages in specific.
