Product Description

Product Description

High-Temperature Resistant LG20  Ladle Slide Gate Nozzle for Steel Continuous 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.
 

The Important Role of Alumina Magnesia Spinel in the Steelmaking Industry

Optimize the Refractory Performance:
Alumina magnesia spinel has a high melting point, excellent thermal stability, and good mechanical strength. It can maintain a stable structure at high temperatures, enhancing the refractoriness and load softening temperature of refractory materials used in steelmaking. This enables the refractory materials to better withstand the hydrostatic pressure of molten steel and the effect of high temperatures.
 

Reduce the Thermal Conductivity:
With a relatively low thermal conductivity, it can reduce the heat loss during the steelmaking process, playing an excellent role in heat insulation and thermal preservation. This is beneficial for reducing energy consumption and improving the efficiency of steelmaking.

 

Inhibit the Penetration of Molten Steel:
Alumina magnesia spinel can effectively prevent molten steel and furnace slag from penetrating into the interior of refractory materials, avoiding the structural damage and performance degradation of the materials caused by penetration. As a result, it can extend the service life of refractory materials and reduce production costs.

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.
