Molten iron insulation agent Product description The molten iron insulation agent is my company to cater to the needs of the market development of metallurgical products. The product effectively substitute the traditional use carbonization rice and other carbonaceous materials, solve the high, transportation agent water covered the defects in use and to appear in the heat loss, and easy to crusting, stick the furnace wall, hang slag etc, it is home to more than in normal use steel mill, and get good use effect and high reputation from the customers. Product features 1. Spread good performance and can even coverage of the iron liquid surface; 2. Strong heat insulation, heat preservation time long, iron temperature drop small; 3. Product ingredients stability, rare slag performance is good, use not crusting, not erosion bag wall, and turn packets clean, reduce the workload of qing bag; 4. Product alkalinity ?

Refers to the standard | 10～18 10～18 30～45 <1150℃ <0.8 |
Usage and dosage
Molten iron by the bag, directly add to the molten iron liquid surface department, addition amount depends on the molten iron residence time 1 ~ 1.5 kg per ton steel according to choose.
- Q: What does fire-resistant insulation coating have?
- Refractory thermal insulation material mainly refers to the inorganic thermal insulation material and composite thermal insulation material. According to the shape, it can be divided into: Finishing of fibrous shape, mineral?cotton, rock wool, glass wool, aluminum?silicate?wool, ceramic fiber, etc. Diatomaceous earth of microporous pile, calcium silicate, expanded perlite,expanded vermiculite,aerated concrete, etc. Foam glass of bubble shape, volcanic ash glass, foamed clay, foamed?concrete, gelatine powder polyphenyl granule heat insulating slurry of pasty form, etc. Their common feature is fire-retardant and firproof. It can be used in buildings with high requirements of fire?rating. Calcium silicate, aluminum silicate and asbestos can also be used for piping insulation of heat transport with high temperature. Hope it is helpful to you.
- Q: What are the refractory materials above 1000℃
- corundum would be fine
- Q: How to do environmental impact assessment for refractory Co., Ltd.
- 1, first of all, the EIA unit and the construction party signed the EIA contract. The contract is only legally valid. Generally speaking, the contract will indicate that the first payment has been received before the work begins.2. Collecting information. This is a very important link in the EIA, which is directly related to the quality of the eia. There is a great variety of data,Generally, the construction party will write a list of environmental impact assessment information.
- Q: whether the aluminum silicate thermal insulation material is fireproof or not?
- aluminum silicate is fireproof, and the melting point is between -40 ~ 800 ℃. Aluminum: it takes the flint clay clinker as raw material, produced by resistance or electric arc furnace fusion and injection fiber-forming process. its characteristics: Low thermal conductivity, excellent thermal and chemical stability, without binder and corrosive material.
- Q: What are the requirements for the performance of refractory materials?
- Performance requirements for electric furnace lining refractory: 1, sufficient refractoriness and softening point. Because of eletric arc, the inner surface temperature of lining can be as high as 1500 to 1800 degree. 2, strong resistance to slag. Because the dust penetrate into the furnace through pore lining, and the refractory material subject to loss, leading to spalling. 3, good thermal and shock resistance. Because during steelmaking, opening door and lifting of the furnace will lead to sudden changes in the temperature of the furnace lining refractory material, so spalling and cracking may occur, damaging the lining premature. 4, enough strength, because the lining is impact during charging, tilted when vibration,and eroded by metal, slag and airflow. 5, the thermal conductivity shall be small, and the conductivity shall be low. The commonly used furnace refractories are dolomite brick, magnesia brick, high alumina brick, silica brick and magnesia ramming etc.. Because of different working conditions of the various parts of the furnace, the refractory materials are not the same.
- Q: What are the types of steel refractory materials
- Large steel ladle usually made with magnesia carbon brick, of course, it contains a intermediate layer (such as good a little high alumina castable), heat insulation layer and heat preservative materials Alumina-magnesia castable is OK for small steel ladle
- Q: Could you tell me how does fire protection standard of decorative material is divided?
- Divided by plate material: structure material, base layel materials and fabric; Divided by fire protecrtion type: easy to burn, difficult to burn, flame retardant, incombustible material. Material has no fire rating, only the different from the time of combustion limit. Building fire protection. Building fire protection is the fire prevention measures of buildings. In the architectural design, fire protection measures should be taken to prevent fires and reduce fire hazards to life and property. Building fire prevention measures includs prophylaxis before the fire and measures during the fires. The former is mainly to determine the fire resistance rating and fire-proof structure, control fuel quantity and space easy to fire site; The latter mainly for fire partition, setting of evacuation and smoke, fire-fighting equipment, etc. In ancient China, flammable wood are usually taken as a building material, which has accumulated many experiences for the building fire protection .
- Q: What are the main materials in concrete fireproofing material?
- fireproofing materials mainly consist of class A incombustible?material and class B1 nonflammable material. Class A incombustible?material: Granite, marble, terrazzo, cement products, concrete products, gypsum board, lime products, clay products, glass, tiles, mosaics, steel, aluminum, copper alloy; class B1 nonflammable material: Ceiling materials, dry wall, fibrous plaster.
- Q: What are the refractories for converter?
- Permanent layer (sintering) magnesia brick, the working lining gunning material for the working layer and the permanent layer gap, using magnesia ramming materials, MgO-C brick brick supply,
