Silica-based nozzle filler stuffing sand for steel making continuous casting
Product Description
SNREF Ladle nozzle filling compound sand is made of high quality imported chrome ore, refined quartz sand and high refractoriness material.
With good fluidity, fast flow, proper sintered layer thickness, anti-erosion and infiltration of molten steel.
Artesian open casting ladle rate reaches 98%, etc. reducing the labor intensity, reducing oxygen drainage, improving the quality of steel products, to ensure the smooth casting process.
The NFC (Nozzle Filling Compound), includes silicon stuffing sand, forsterite stuffing sand, high alumina stuffing sand, and chrome stuffing sand, among which chrome stuffing sand has the most favorable effect in application.
Meanwhile, our nozzle-filling sands have been developed to meet the needs of steel making facilities worldwide. Each blend is carefully designed to enhance the free flow of steel from the ladle regardless of steelmaking practices. This is achieved through custom blending which affords each customer a product specific to their manufacturing needs.
Type of Nozzle Filling Compound:
1. Chromite Nozzle Filling Compound
2. Silica Nozzle Filling Compound
3. Forsterite Nozzle Filling Compound
4. High Aluminum Nozzle Filling Compound

Application
Application Fields and Market Situation
- Application Fields
- Steel Industry: It is the main application field of nozzle filling sand compound and is widely used in ladle nozzles of various steelmaking furnaces (such as converters, electric furnaces, etc.).
- Other Metallurgical Industries: In some non-ferrous metal smelting processes, nozzle filling sand compound may also be used, but its usage requirements and characteristics may be different.
- Market Situation
- With the development of the steel industry, the demand for high-quality refractory nozzle-filling sand compounds continues to grow. The market competition is also relatively fierce. Each manufacturer continuously researches and develops new products and technologies to improve the performance and quality of nozzle filling sand compounds to meet the increasingly improved production requirements of steel enterprises. At the same time, the market price is also affected by various factors such as raw material price fluctuations, production process level, and product quality.
Refractory nozzle filling sand compound plays an indispensable role in the steel and related metallurgical industries. The continuous improvement of its performance and quality is of great significance for improving the efficiency and quality of metallurgical production.

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.
