Deep Burnt Ladle Flow Control CS80 Slide Gate Plate for Steel Making

Product Description

Deep Burnt Ladle Flow Control CS80 Slide Gate Plate for Steel Making
 

In the steel making process, the sliding gate plate nozzle system at the bottom of the ladle, consisting of slide gate plate, upper nozzles, lower nozzles, and seating well block, 
works in concert to ensure the safe and precise control of molten steel pouring.
 
Below is a detailed explanation of their collaborative processes and functions:
 
1. Functions and Structures of Each Component
Component  
Role Material and Characteristics
Well block Backing Brick, Embedded in the bottom of the ladle, it fixes the upper nozzle and provides a supporting structure.
High-alumina or magnesia-carbon materials, resistant to high-temperature erosion. 
Upper Nozzle, Directly contacts molten steel and guides it into the sliding nozzle system.
Aluminum-carbon or zirconium-carbon materials; the inner hole is flared to reduce turbulence.
Sliding Gate Plates, Controls the flow rate of molten steel through horizontal movement
(flow is regulated by misaligning the upper and lower slide gate plate),
Composite refractory materials (such as Al2O3 - C), with an anti-stick coating on the surface.
Lower Nozzle, Guides molten steel from the slide gate plate to the tundish or mold;
some designs allow for disassembly and replacement.
Resistant to rapid heating and cooling, often containing ZrO2 to enhance erosion resistance.
 
2. Collaborative Workflow
1) Closed State (Preparation Phase)
Slide gate plate Position: The molten steel flow holes of the upper and lower slide gate plate are completely misaligned, blocking the passage of molten steel.
Sealing Assurance: Hydraulic or spring mechanisms press the slide gate plate tightly to prevent molten steel leakage.
Preheating Treatment: Baked to a temperature of over 1000°C before use to avoid blockages caused by solidified steel.
 
2) Flow Control Phase
Slide gate plate Movement: The lower slide gate platemoves slowly to partially align the holes of the upper and lower slide gate plate. Molten steel flows out through the upper nozzle, slide gate plate holes, and lower nozzle.
Flow Control: The flow rate is controlled by adjusting the displacement of the slide gate plate (for example, 50% alignment) to avoid turbulence and splashing.
 
3) Pouring Process
Dynamic Adjustment: The opening of the slide gate plate is fine-tuned in real-time according to the tilting angle of the ladle and the requirements of the billets.
Anti-blocking Design: The flared structure of the upper nozzle reduces impurity accumulation; argon blowing in the lower nozzle prevents the formation of nodules.
 
4) Closing Phase
Quick Cut-off: At the end of pouring smelting, the slide gate plate are quickly and completely misaligned to cut off the flow of molten steel (to avoid slag carryover).
Emergency Measures: In case the slide gate plate get stuck, the backup hydraulic system or a manual wrench is used to force them to close.
 
Conclusion
The core of the collaboration of the sliding nozzle system lies in its sealing performance, high-temperature resistance, and precise control.
The seating well block backing brick provides support, the upper and lower nozzles guide the flow of molten steel, 
and the slide gate plate regulate the flow rate through mechanical movement, jointly ensuring the safe transfer of molten steel from the ladle to the mold.
 Deep Burnt Ladle Flow Control CS80 Slide Gate Plate for Steel MakingDeep Burnt Ladle Flow Control CS80 Slide Gate Plate for Steel MakingSlide gate plate brick 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.Deep Burnt Ladle Flow Control CS80 Slide Gate Plate for Steel Making

 

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

Deep Burnt Ladle Flow Control CS60 CS80 Slide Gate Plate for Steel Making: 


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.

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.
