Product Description

 

Refractory Slide Gate Plate for Steel Making 4200 

Product Description

Usage Environment

Sliding nozzles are key devices in the continuous casting process of steelmaking, mainly used to control the flow of molten steel from the ladle to the tundish. They operate in an extremely harsh high - temperature environment, with the temperature of molten steel usually reaching about 1500 - 1600°C. Moreover, they are exposed to the scouring of molten steel and slag, as well as the chemical erosion of various elements in the molten steel and slag. Meanwhile, during the casting process, they need to endure rapid temperature changes, resulting in significant thermal stress inside the materials.
 

Composition

Refractory Materials:
These are the main components of sliding nozzles. Common refractory materials include aluminum - carbon (Al-C), aluminum - zirconium - carbon (Al-Zr-C), magnesia - based materials, and corundum - based materials.
For example, aluminum - carbon materials are often used in general - purpose ladle sliding nozzles, which are composed of sintered alumina and carbon components. Aluminum - zirconium - carbon materials, which add zirconium - containing components on the basis of aluminum - carbon materials, are widely applied in large - scale refined ladle sliding nozzles.

Company Profile

Shandong Sinorefractory New Materials Co.,Ltd(SinoRefractory)has been focusing on international marketing of flow control refractories in iron and steel industry for 18 years.
Started in year 2007, SinoRefractory is the second generation of refractories export enterprise developed from Emei group, supported by one of China's largest production bases in functional refractory materials.

Through years of development in the field of functional refractory materials, SinoRefractory aims at researching,marketing and exporting premium quality slide plates, nozzles, well blocks,purge plugs,nozzle filing sand,refractory castables, slide gate mechanism,tundish refractories to global markets.

In 2021, SinoRefractory was spun off from Emei group. In 2022, in order to expand into broader product areas and commit to becoming a high-end refractory materials supplier,SinoRefractory became an affiliated enterprise of Sinosteel Luoyang Institute of Refractory Research.

Following the establishment of this strategic collaboration,SinoRefractory has achieved significant advancements in new product area development,technical support and market expansion.
