Ladle castables are a kind of refractory castables specially used for ladles. They have been widely used in many fields with their excellent performance. The following is a detailed summary of the application of ladle castables:
1. Main application areas
①. Ladle lining
Ladle castables are mainly used for the lining of ladles, including the bottom, side walls, slag line and other parts. These parts are in direct contact with high-temperature molten steel and slag, so they need to have excellent refractory properties and corrosion resistance.
Ladle castables can resist the erosion of high temperature and slag, protect the ladle structure from damage, and thus extend the service life of the ladle.
②. Metallurgical industry stoves
Ladle castables are also widely used in various metallurgical industry stoves, such as heating furnaces, soaking furnaces, etc.
These stoves operate at high temperatures and need to have excellent refractory properties and stability. Ladle castables can meet these requirements and ensure the normal operation and safety of the stoves.
③. Other smelting industries
In the smelting industries such as petroleum, chemical, building materials, and electric power, ladle castables are also widely used.
It can be used for the lining or coating of various high-temperature equipment to improve the high-temperature resistance and service life of the equipment.
2. Specific application scenarios
①. Ordinary ladle
Ladle castables can be used for the working lining of ordinary ladle to improve the high temperature resistance and corrosion resistance of the ladle.
It can protect the ladle from the erosion of high-temperature molten steel and slag, and extend the service life of the ladle.
②. Refining ladle
During the refining process, the ladle needs to withstand higher temperatures and more complex chemical environments.
Ladle castables can withstand these harsh conditions and maintain the integrity and stability of the ladle.
③. Electric furnace ladle
Electric furnace ladle will generate a lot of heat and slag during use.
Ladle castables can resist the erosion of high temperature and slag and protect the structure of the electric furnace ladle from damage.
④. Other equipment
Ladle castables can also be used in scenes such as the installation of refractory weir plate prefabricated parts for intermediate pouring of continuous casting.
In addition, it can also be made into casting bricks for use to meet the needs of various high-temperature equipment.
3. Application advantages
①. High refractoriness
Ladle castables have high refractoriness and can withstand the erosion of high-temperature molten steel and slag.
②. Strong erosion resistance
It has excellent slag resistance and spalling resistance, and can maintain the integrity of the ladle lining for a long time.
③. High adhesion rate and easy spraying
Ladle castables have a high adhesion rate, are not easy to fall off, and are easy to spray and repair. This reduces maintenance costs and improves the use efficiency of equipment.
④. Good construction performance
Ladle castables have good construction performance and are easy to apply and shape. This ensures accuracy and efficiency during the construction process.
⑤. Improve smelting efficiency
The reasonable selection of ladle castable materials and the use of efficient construction processes can reduce the heat storage and heat loss of the ladle, thereby reducing the energy consumption and production costs of the steel plant. At the same time, it can also improve smelting efficiency and ensure the stability of molten steel quality.
Ladle castables have a wide range of application value in multiple fields and specific application scenarios. Its application advantages such as high refractoriness, strong corrosion resistance, high adhesion rate, easy repair and good construction performance make it an ideal material for these high temperature environments.
