2. Description

China Black Silicon Carbide Abrasive for Refractory features high hardness(HV=3100-3300kg/mm2), is brittle and has a sharp nature and maintain certain electrical conductivity and thermal 

conductivity and thermal conductivity.

P Series: P16-P2500, 27 Grit Numbers

F Series: P14-P1200, 30 Grit Numbers

 

3.Advantages

1). Corrosion resistance, high strength, high hardness. 

2). Good wear-resisting performance,resist to shock. 

3). It is a cost-effective substitute for Ferrosilicon. 

4).It costs less than ferrosilicon and carbon combination. 

5). It has no dust nuisance while feeding the material. 

 

 

4. Applications

The abrasive tools made from China Black Silicon Carbide Abrasive for Refractory is applicable to non-ferrous materials with tensile strength, such as nonferrous metals, wood, leather, plastic, rubber, stone material, gray

cast iron, silicate material (glass, ceramic, concrete and refractory matter), etc. Adding a proper amount of black

silicon carbide as deoxidant during the smelting of steels can significantly improve the quality of  steels. Due to its heat resistance, resistance to chemical attack and thermal shock resistance, it is widely used in high quality

refractory matter and other industries.

Q:Physical and chemical indicators of various refractory.
There are too many of them.
Q:Concrete composition and function of magnesia bond used in refractory
According to the chemical composition and use can be divided into metallurgical magnesia, magnesia brick, magnesia brick, magnesia brick, magnesia calcium brick, magnesia brick and other varieties. Its performance is greatly affected by CaO/SiO2 ratio and impurities. High purity magnesia brick refractoriness under load and thermal shock resistance are better than the general magnesia brick. High refractoriness, has good resistance to alkaline slag and iron slag, is a kind of important senior refractories. Use of magnesia product production by sintering process, sintering temperature is 1500 ~ 1800 DEG C, in addition, you can also add chemical bond, made of brick and unshaped refractory material. Mainly used in open hearth furnace, electric furnace, converter, oxidation non-ferrous metal smelting furnace, cement kiln and alkaline refractory kiln etc..
Q:What is the limit of fireproof rolling shutter?
Fire proof door can be divided into Serie A, B and C in terms of fire endurance limit, fire resisting limit are not should be less than 1.20h, 0.90h and 0.60h. Set firewall has difficult sites can use fire shutter fire partition separating, when the back fire surface temperature rise refractory limit determination conditions of fire shutter, the fire resistant limit not less than 3H; when employed does not include back fire surface temperature rise do fireproof limit determination conditions of fireproof rolling curtain, on both sides of the shutter should be set up a separate closed type automatic water spraying system protection, sprinkler system continuation of time should not be less than three hours.
Q:What are the fireproofing materials of the external wall included?
Facades a fireproof material comprises three anti-cloth, fireproof cloth, plastic cloth, PVC tarpaulins, flame retardant cloth, Hair Dryers cloth, automobile tarpaulin, PVC three anti-cloth, the freight yard covered cloth, PVC coated fabric, canvas industry etc., are widely used in automobile canopy cover cloth, trains cover cloth, ships cover cloth, cloth covered open-air yard, industrial and agricultural fields; used in glass, timber, fertilizer plants, steel plants, machinery metal factory, feed mill, grain storage, container plants, oil refineries, packaging plants, paper plants, air conditioning plants, logistics, ore factory, fleet, rail, sea and so hoping to 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:Is there anyone who can explain how to grade the level of fire insulation board?
1, Combustion performance of building material is divided into the following several class according to China's national standard GB8624-97 Class a: Non combustible building materials: Non-conbustible material. Class B1: Refractory building materials: Flame retardant materials have good flame retardant effect. It hardly catch on fire in the case of open flame and high temperature, do not spread fire quickly, and when the fire source is removed, fire will be stopped immediately. Class B2: Combustible building materials: Combustible materials have certain flame retardant effect. In case of fire or under high temperature, it will immediately burst into flames, easily leading to spread of fire , such as poles, wooden frame, timber, and wood stairs. Class B3: Combustible building materials: Without any flame retardant effect, will be burnt easily, resulting in high risk of fire. I Hope my answer will help you.
Q:What types of steel are silicious quicksand and chromium quicksand used in respectively?
Chromium quicksand can be used in steel-making process that has longer refining time like LF, VD and RH, in stainless steel drainage and thin plate drainage agent. Silicious quicksand is used in short steel-making process, process that is less than 45 seconds or process without refining. You can consult Hua Heng for details or inspect it by yourself.
Q:What is refractory brick?
Capability1. Refractory brick is also known as firebrick. It is faint yellow or brownish. Refractory brick with 770 ℃ at high temperatures is called for short firebrick. It is mainly used for building and smelting furnace. It is a refractory material made by fring refractory clay or other refractory material.
Q:How much modulus is used as refractories material of sodium silicate.
Storage and use are very convenient, especially for mechanized and the evenly refractory material and the sodium silicatemodulus is generally...2. transportation. The appearance of product is pure white. Instant powdered sodium silicate, also known as instant sodium metasilicate.4 to 3, in powder form, automation. in the range of 3, hydrated sodium silicate
Q:what's the fire endurance of fireproof panel?
fire endurance of fireproof panel can reach 3 hours. For example, 12 mm non-asbestos fiber reinforced calcium silicate board, fireproof panel, two single 75 keel. through the monitoring of national fireproof construction materials quality supervision center, it's security and refractory time will reach over 3 hours. fireproof panel, also called fire resistance board, scientific name is thermosetting resin impregnated paper laminated wood,english abbreviation HPL(Decorative High - pressure Laminate) is fire resistant building material for surface decoration and has rich surface colors,lines and special logistics performance, it's widely used in interior decoration, furniture, cabinets, laboratory table, external wall, etc.
