Product Description

LG21 Slide Gate Plate Refractory for Molten Steel Flow Control

Product Description

 Slide gate plate is becoming more and more important in modern iron and steel smelting process, and becoming an indispensable part of smelting.
It is a molten steel control device of continuous casting machine in the process of casting.
It could precisely adjust the molten steel flow rate that from ladle to continuous casting tundish to balance the inflows and outflows of molten steel, which makes it easier to control the continuous casting operation.
Now, slide nozzle system is widely used in ladle and tundish ladle in worldwide.

 

Our product line features a comprehensive range of slide gate plates:

>Classified by materials:
1. Alumina-carbon
2. Alumina-zirconia-carbon
3. Basic materials (Magnesia-carbon, Magnesia-based, Alumina-magnesia- carbon)
4. Zirconia systems (inlaid type)

>Classified by workmanship:
Various combination of workmanship Unfired, Fired, Oil-impregnated, Heat-treated, etc. >Classified by firing temperature:
1. Unfired
2. Medium-temperature firing (800-1200°C);
3. High-temperature firing (1500-1800°C)

The features of 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

Application

Refractory sliding plates are essential in high - temp industrial processes like metallurgy and casting. Their applications:
1.Steel Metallurgy
Ladles: Bottom plates seal molten steel post - tapping, open mechanically/hydraulically to control flow, reducing oxidation.
Tundishes: Regulate steel flow to molds; quick - close for safety during issues.
2.Non - Ferrous Metallurgy
Copper Smelting: Control copper liquid flow; need high corrosion resistance.
Aluminum Electrolysis: Manage purified aluminum flow into molds for precision.
3.Casting
Cast Iron: Control iron pouring, allow flexible operation.
Cast Steel: Ensure precise temperature and flow control for varied production.

>Purging Plug Application characteristics :

In order to adapt to more and more strict refining conditions(especially special steel), and to meet the requirements of increasing ladle

life, the volume of plug becomes bigger and bigger. However the traditional slit type plug has single material and single structure, easy

to cause the phenomenon of tranverse fracture and failure of air blowing.

The Segment plug has successfully soved the problem of fracture existing in traditional slit plug. Significantly increasing the stability

of refining process, ensuring the realization and improvement of quality refined steel.
