2. Service Result for slide gate plate and nozzle system:
Service life depends on many points:
1)Different Raw Material,
2)Production Process(Firing temperature, oil immersion, drying temperature...)
3)Steel type
4)Steel making condition
5)Different operation mode
And so on....
3. Type of production design
1) High Temperature Burnt Slide Gate Plate and ladle nozzle system
High performance ladle slide gate plate refractories adopts tabular alumina, carbonaceous material and zirconia-containing material as main raw materials, adds in high performance antioxidants, uses phenolic resin as binder, formed under high-pressure and burned under high temperature. Mainly used in large and medium-sized ladles.
2) Low Temperature Burnt Slide Gate Plate and nozzle system
Tabular alumina, zirconia-containing material and spinel as major raw materials, adding in special metal, using phenolic resin as binder, being burned under low temperature to produce the products, Mainly used in small and medium-sized ladle.
3) Un-burned Slide Gate Plate and nozzle system
Without the process of burned, tar impregnated and distilled, simple processing. Mainly used in small and medium-sized ladle.
4. Advantage of Our slide plate and nozzle system
Our Slide Gate Plate refractory adopts High quality bauxite material , also takes tabular alumina, carbonaceous material and zirconia-containing material as main raw materials, adds in high performance antioxidants, uses phenolic resin as binder, formed under high-pressure and burned under high temperature. The slide plates have the advantages of high strength, good erosion resistance, thermal shock resistance and good stability etc., mainly used in large and medium-sized ladle.
The slide plate is exposed to high temperature molten steel repeatedly, especially the cast hole part, the erosion is serious, this require the slide plates obtaining features of High strength, excellent corrosion resistance, anti-stripping, to ensure no steel leak during pouring process.
The features of SINOREFRACTORY Slide gate plates:
1. Flatness of sliding surface ≤0.05mm
2. High mechanical strength
3. High resistance to contamination of molten steel and slag
4. Excellent oxidation resistance
5. Good thermal shock stability

Below are some FAQ and answers about ladle and tundish flow control refractories:
Q: What are the requirements for refractories for ladle?
A: The requirements of refractories for ladle mainly include:
* high temperature resistance
* thermal shock resistance
* resistance to the erosion of the slag
* high temperature with sufficient mechanical strength
* the lining has a certain degree of expansion
Q:What are the reasons for the destruction of refractories for ladle?
A: The main causes of damage are as follows:
When the ladle transports high-temperature molten steel, the high-temperature molten steel and slag at about 1680ºC scour and erode it, especially in the slag line part, the scouring and erosion is more serious, and it is an important factor to decide the service life of the ladle.
LF and other extra-oven refining treatment on the unburnt brick damage is serious.
Q:What steel grades are different materials of slide plate bricks suitable for respectively?
A: Q:What steel grades are different materials of slide plate bricks suitable for respectively?
A: Different materials of slide plate bricks are applicable to different steel grades. For example,
Al2O3-ZrO2-C slide gate plate can be used as ladle sliding gate plate due to its excellent erosion resistance and thermal shock stability, which can adapt to the casting of various steel grades, and ther are the following materilas based on customer's steel making condition: the MgO-C, MgO-Al-C, MgO-Al-C, MgO-Al-C, MgO-Al-C, MgO-Al-C, MgO-Al-C, MgO-Al-C, MgO-Al-C, and so on.
