Product Description

Product Description

1QC Ladle nozzle refractories sliding gate plate for steel casting

SNREF Slide Gate Plate 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.
 


Main types of slide gate plate

1) C series Small size Slide Plate---mainly for Indonesia, Vietnam, Myanmar, Thailand, for 5-20 tons ladles.
2) QC series Slide Plate mainly for India, Turkey,Middle East, Indonesia, Pakistan, Italy , mainly for 20-30 tons ladles.
3) B250 , safllow, HB250, Mainly for Pakistan, Middle East market.
4) Flocon sereis Slide Plate mainly for Turkey, Middle East, Italy, Braizl, and soon.
5) CS Serise Slide Plate mainly for Europe countries.  mostly for larges ladles such as more than 120 tons.

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.

FAQ

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.
