0-1mm;1-3mm;3-5mm;0-10mm;0-30mm
50 to 325mesh (90% through)
Product feature:
high temperature performance and high-density, strong anti-permeability ability and easy to rapid sintering, very thin sintered layer,good thermal shock stability, strong slag-resistance, long service life and so on.
Product function:
Apply to the construction of bottom and wall of all kinds steel making electric arc furnace and ferroalloy smelting furnace for hot charging of hot metal and second hand steel
Product usage:
Mainly used in producing common magnesite brick, magnesite aluminum brick, magnesite chrome brick, gunning mix, hot patching mix for converter and EAF ect .
Product Advantage:
Our factory produce the products of the Dead-burned magnesite are selected natural magnesite, it is produced by mine-selecting, purifying, calcimine in shaft kiln. It is an ideal material for unshaped refractory material, the final products are used in open hearth furnace, electric furnace bottom and furnace's lining tamping.
- Q: How long is the duration of fire resistance of autoclaved flyash-lime bricks?
- The fly ash effect will continue to play a role in a considerable period of time, so the long-term strength keeps strengthening, the average age of 90 days of strength will grow 80%-100% more than the 28 days.
- Q: The mechanism and function of antioxidants in carbon containing composite refractories are briefly described.
- With the advantages of carbon refractories especially excellent slag resistance and high heat stability, but graphite under high temperature oxidation, in order to improve the oxidation resistance of carbon composite refractory materials, often adding a small amount of antioxidants, to improve the oxidation resistance of carbon composite refractories. Antioxidant additives commonly used in metal powder, silicon powder, magnesium powder, silicon carbide powder and so on.
- Q: Do you know the refractories?
- Alkaline material products: MgO, CaO based crystalline phase, because MgO and CaO are alkaline earth oxides, so it is called alkaline refractory. Their high melting point, alkali resistance slag (C/S > 2) corrosion ability is strong, belong to advanced refractory materials, but they are easy to hydration. Magnesia chrome brick, dolomite brick, brick olive and other products, the main chemical composition is MgO, CaO China also belongs to alkaline materials.
- Q: How many types of special refractories are there?
- Metal ceramics, high temperature coatings, high temperature fiber and other reinforced materials
- Q: What type of firebrick does TZ-3 represent?
- Height is 65mm, length is 230mm, and width is 114mm, that is the t-3 firebricks which meet the national standard.
- Q: What a blast furnace refractories generally?
- refractories for blast furnace include carbon brick and silicon-aluminum refractory. BF carbon brick inlcudes half-carbon charcoal bricks, microporous charcoal brick, ultra porous charcoal bricks, graphitic brick and mould pressing charcoal brick. tiles and molded graphite small charcoal bricks. I hope my answers above are helpful to you and your ideal anwers.
- Q: Which kind of refractory floor is easy to use? ?
- Recommend: Yong Wei fireproof board Henan Yong Wei Anfang Co., Ltd., located in Qinbei industrial agglomeration area, Qinyang City, Henan Province, was founded in 1995. It strated from the initial one fire decorative plate production line. After years of development, it has become the biggest fireproof decorative board production base with 25 fireproof board production lines.
- Q: Does refractory belong to stone, building materials or other?
- Refractories belong to organic non-metallic materials.
- Q: What's the difference of fire-resistant material's density, specific gravity and bulk specific gravity?
- It usually used to test lightweight refractory. Density can be divided into apparent density (usually called as density) and true density: apparent density includes blow hole inside the sample; Unit weight is using quality to divide volume of sample and specific weight is used to represent liquid.
- Q: What crusher is used for raw material of broken refractory material? What is the rough crushing process? What are the materials? Thank you!
- Common faults and causes of magnetic?separator. 1. Motor of magnetic?separator is overheated and its sound is not normal. Reasons for this failure are: 1) lubrication of bearing is bad or badly worn; 2)fan blade falls off or wears; 3)bad contact of switching circuit or disconnected to run a single phase; 4) voltage is too low. 2. Reasons for this failure due to overheated speed reducer are: 1) lack of oil or poor kerogen; 2) wear between gear and worm, or poor mesh; 3)poor lubrication of bearing or serious wear. 3. The sound of magnetic?separator during operation is abnormal, lattice ball mill. Cylinder is stuck by obstacle, and even the cylinder can not rotate. The bottom box vibrates. Reason for this failure is often that it is stuck by objects in drag flask, otherwise magnetic?patch falls off so that the cylinder screaks and pierce tube when it is serious. At this time, car should be stopped for maintenance and troubleshooting. Only when we master common faults and reasons of magnetic separator can we timely identify problems and solve problems. Better maintenance and repair of magnetic?separator equipment are an important prerequisite to properly use equipment and ensure the construction.
