Steel casting refractory slide gate plate bricks primarily encompass the following scenarios:
1. Small Size Slide Plate - Al-C;
Slide gate plate models include: 1QC, 2QC, 1BK, 2BK, C51, CS60/80, LS50/70/90, LG20 21 22 (VSV374 421 441)
Models like FLOCON 4200/6300/ B50/250, and LQLV50/150/180 also provide excellent solutions.
2. Middle & Large Size Slide Plate - AL-Zr-C; Al-C; or Both. Models include CS60/CS80, LS50/70/90, LG20 21
3. Special Steel (Ca-treatment steel) - Al-Spinel; Mg Spinel formulations available.
The slide gate plate is the linchpin in slide gate systems, crucial for regulating the flow rate of molten steel.
In the face of repeated exposure to high-temperature molten steel, especially at the cast hole, slide plates must exhibit high strength, outstanding corrosion resistance, and anti-stripping properties. These ensure no steel leakage during the pouring process.
Outstanding Features of LQ Slide Gate Plates:
1. Impeccable flatness of sliding surface, maintaining ≤0.05mm tolerance
2. Superior mechanical strength to withstand demanding conditions
3. High resistance to potential contamination from molten steel and slag
4. Exceptional oxidation resistance for enhanced durability
5. Excellent thermal shock stability, ensuring longevity and reliability
Seal protection for slide gates focuses on both the upper slide plate and nozzle, as well as the lower counterparts. After one or two casting cycles, the lower slide plate and nozzle necessitate replacement and reinstallation. The sealing materials, often gaskets made of fiber or fireclay, contribute to preserving the high cleanliness of molten steel and the uniformity of the internal quality of slabs.

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.
Slide gate plate brick is becoming more and more important in modern iron and steel smelting process, and becoming an indispensable part of smelting.
Feature of SNREF slide gate plate, nozzle and well block:
1.Excellent thermal stability
2.High temperature strength
3.Resistance to molten metal and slag
4.Consistency in shape and size
5.Ability to sustain mechanical treatment without detriment to the surface integrity
Adopting tabular corundum, fused alumina, fused alumina zirconia, zirconium mullite as raw materials, through the addition of moderate micro and fine metal powder, by reaction under high temperature, to increase the high temperature performance of plates. Through the adding of moderate boron carbide powder to increase the oxidation resistance of plates. The bonding agent is phenolic resin with high solid content and high carbon residue.
After forming, adopting advanced heating treatment technology, through impregnating, burning to form high performance slide plates. With features of good thermal stability, excellent erosion resistance, stable consistency in shape and size, mainly suitable for ladles over 180 tons or converter slagging slide gate systems.

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: 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.
