Product Description

LS50 Ladle Slide Gate Plate with Nozzle for Steel Molten Flow Control 
 
Product Description

Slide Gate Plate is a critical refractory component for steel continuous casting, installed at ladle bottoms. It controls molten steel flow by sliding upper/lower plates to regulate the channel opening, ensuring stable mold feeding and preventing defects/hazards from flow instability. Key specs: excellent resistance to 1500-1700°C steel/slag erosion, high strength against thermal shock/sliding forces, and superior wear resistance for repeated use. Vital for enhancing casting efficiency, quality, and safety.

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

>General Models for Slide Plates :
SAFFLOW, S2, CS60/80/100, LS50/70/90, C10/40/51, B50/60/250, 1QC/2QC, FLC4200/6300, FT160, 1BK/2BK, LG20-22, VSV-Series.

>Classified by materials:
1. Alumina-carbon
2. Alumina-zirconia-carbon

Application
Refractory sliding plates play a crucial and indispensable role in numerous high-temperature industrial fields such as metallurgy and casting. The following elaborates on their specific applications:

I. Steel Metallurgy Industry
1.Ladles: They have a refractory sliding plate at the bottom. After molten steel is tapped into the ladle from the converter, the plate closes to stop leakage. At the refining or casting station, it opens mechanically or hydraulically to let molten steel flow into equipment like a refining furnace or tundish at a set rate, reducing secondary oxidation and enhancing steel quality as it can open and close multiple times.
2.Tundishes: As a transition for molten steel from ladle to mold, the tundish's refractory sliding plate is vital. It adjusts the flow rate into the mold for continuous casting stability. In case of mold strand issues like breakout risk or slab quality problems, the relevant plate can be quickly closed to stop molten steel flow and ensure production line safety.

II. Casting Industry
1.Cast Iron Casting: The refractory sliding plate at the bottom of the casting ladle controls molten iron pouring. When ready, the operator opens it for even flow to avoid defects and can quickly close it during the batch for mold changes or suspension, adding flexibility.
2.Cast Steel Casting: Due to strict temperature and flow control needs, the refractory sliding plate is essential. It works in a high-temperature and high-pressure environment to ensure proper molten steel injection and can quickly switch tasks for multi-variety, small-batch production.
