Unshaped Refractory High Alumina Castables for Steel Making

 

Product Description

Refractory castable and mortar  products for the alumina content of 50% -60% of the cement matrix.

Aluminate cement CA-50 series products, the main mineral phase composition of CA-phase (a calcium aluminum acid 2 aluminum 

acid a calcium). Therefore, not only products with a relatively high temperature use of performance, but at the same time have a 

reasonable and stable hydration of the performance, rapid growth in outstanding physical strength properties. The company's 

production of aluminate cement CA-50 series based on the development of cement hydration and the relative intensity of the 

physical strength to be the value of the product into different grades, so that customers according to their demand for the product 

and the use of conditions to choose. 

Meanwhile,through the production process of the optimization of product performance so that it can adapt to both the monolithic 

refractories different construction methods (such as: casting, injection), also can meet a variety of castable formula system, such as:the traditional combination of high alumina cement castables and medium-cement castables, the performance of the constructionmade by the different requirements.This series of product does not contain any additives to ensure product suitability and stability.

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.
