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: 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: How many kinds of fireproof materials are there in the market?
A-level materials are the best which will not burn while the B-level materials are made of combustible materials which can burst into flames.
Q: Who knows the fire rating of fire?partition with steel stud?
1 hour. It is in line with the fireproof test standards of national building materials . CaSo4.2H2O is molecular structural formula of gypsum which contains 20% water, crystal water and free water. When 10% water slowly evaporates on the flame surface, there is still 10% crystal water. Itself is grade A fire retardant material. It can reach up to four hours at most.
Q: Which refractory quality inspection authority is good?
Research Institue of Refractory Materials in Luoyang, Henan Some of our samples are made there.
Q: How much is the duration of fire resistance of the porous brick shale?
The duration of fire resistance of the porous brick shale could reach 1,580℃—1,770℃. It is predominantly applied in coke oven masonry and building, glasses, porcelains, carbon calciner, and the vault of thermal furnuces of refractory bricks as well as other load-bearing elements, and high temperature bearing parts of cowper stove. But it should be aware that it can’t be used in thermal equipment below 600℃ and with large variation of temperature.
Q: What does the function of SiC for refractories?
Anti-acid corrosion anti-skinning
Q: How to choose refractory material
Refractory fiber according to different raw materials, there are aluminum silicate, quartz, alumina and graphite, refractory fiber. Commonly used aluminosilicate refractory glass fiber is amorphous, including ordinary aluminum silicate fiber, high-purity aluminum silicate fiber, chromium silicate fiber, long-term use temperature of 1000-1200 degrees.
Q: How to apply the alumina powder on refractories?
The most common one in use is the refractory bricks.
Q: How to choose the material of refractory?
Long using temperature of aluminum oxide fiber is 1400 ℃, containing chromium aluminum silicate fiber, quartz, high purity aluminum silicate fiber, long-term use of temperature is 1000-1200 ℃ has aluminum silicate refractory fiber according to different raw materials, advanced refractory fiber (such as alumina. Commonly used vitreous aluminum silicate refractory fibre is amorphous, zirconium oxide refractory fibre) using temperature is 1700 ℃ view as >and the best temperature is 1300 ℃. Crystalline refractory fiber are polycrystalline mullite fiber, including ordinary aluminum silicate fiber, alumina and graphite refractory fiber, etc. The use of common refractory fiber temperature is 1150 ℃;>
