Product Description:

Long nozzle
They have excellent properties of thermal shock resistance, abrasion and corrosion resistance, bake free and long life.
Breathable ring is composited inside nozzle bowl, achieves argon-blowing protection of nozzle end, and prevents secondary oxidation which satisfying requirements of high pure steel.

Submerged nozzle
They have excellent properties of abrasion resistance and oxidation to molten steel, thermal shock resistance, corrosion resistance to slag.
The nozzle outlets are special handled by materials with good abrasion resistance in order to guarantee stable outlet angle of molten steel, and satisfy requirements of molten steel flow field design of crystallizer and production, which ensure stable liquid level.

Ladle upper nozzle & collecter nozzle
With the characteristics of high strength, good thermal shock resistance, oxidation resistance, scouring resistance, erosion resistance, small reaming and long service life, etc.

Q:What are the ingredients of brick?
Is the most traditional brick masonry material, its composition is clay as the main raw material gradually to the development of industrial waste utilization of coal gangue and fly ash, and by solid and hollow porous to development, development by sintering to non sintering.
Q:the amount of per square refractory brick of Various specifications and thickness of the refractory brick wall
9 grams-47. 7 grams- 47 calculate by your own according to the actual volume; cubic centimeter; 2.2 grams Clay brick 2: 1; 3, high alumina brick 3; cubic centimeter; standard density, cubic centimeter: 230mm * 114mm * 65mm, diatomite insulation brick 0, you can calculate the reference value
Q:What kind of refractory brick is used for industrial furnace?
High aluminum in cement plant. Mills use MgO-C, high aluminum ect; glass furnaces use Luo 8. different kiln and parts use different bricks.
Q:How much is a refractory brick?
There are many kinds of refractory bricks, you have to look at what is material, the material is not the same, the price is not the same, clay brick is the cheapest, probably hundreds of dollars a ton, and corundum brick a ton of several money, silicon carbide, silicon nitride, and more expensive. And this thing is generally on t sell, the price is by a single block after conversion.
Q:What is the standard size of high alumina brick?
Standard brick: 230 x 115 x 65; four points: 230 x 115 x 40; three points: 230 x 115 x 30; 150 x 120: Brick gable. Light weight brick 1 to 1.7 kilograms; heavy clay superscript brick weighs 3.75 kilograms; light 30 plates 0.79 kilograms; light 40 plates, 1.05 kilograms.
Q:How to reinforce a porous brick foundation?
Enlarged section method: it is used for the relatively shallow foundation with independent depth, strip foundation, raft foundation, box foundation and pile foundation applicabilityPoor.
Q:Solid brick and clay brick which is expensive
Because the sintered clay brick belongs to the material which destroys the cultivated land, the national policy restricts the use and is forbidden to use the standard brick. But it can be used in the base part.
Q:What mud is the refractory brick made of?
The main material of the ordinary refractory brick is clay, the main component is aluminium oxide.
Q:Are buildings allowed to use red bricks?
Is the red brick with clay, shale, coal gangue as raw materials, crushing, mixing kneading with artificial or mechanical pressing, sintering and building bricks after drying at 900 centigrade temperature by oxidizing flame firing, invented by the babylonians.
Q:What are the weak points of clay bricks?
SiO2 and Al2O3 in clay bricks form eutectic, low melting point silicates with impurities during sintering, and are surrounded by mullite crystals. Clay brick belongs to weak acid refractory products, it can resist acid slag and acid gas corrosion, and its resistance to alkaline material is a little worse. The thermal performance of clay brick is good, it is fast and cold. The clay brick refractory brick and be roughly the same, up to 1690~1730 DEG C, but the load softening temperature is 200 degrees Celsius above the low brick. Because clay bricks contain crystalline Mullite with high refractoriness, they contain nearly half of the amorphous glass phase of low melting point.
