The high performance slide plates manufactured by HYRE show the feature of lower percentage of carbon content, which will avoid the working surface of slide plates from being greatly roughened. So they are more suitable to both low-carbon and super-low-carbon steel grades. And also it provides much higher fired strength which will reduce the bores-enlarging as small as possible while sliding repeatedly.
HYRE serial high performance slide plates are produced by free-of-tar-impregnation technology, so it will benefit environment protection and also improve the operating surroundings of workers.

Slide Gate Plate is a critical component in the continuous casting process, used to control the flow of molten steel from the ladle or tundish to the crystallizer. The following is a detailed description:
Role and Function
- Flow Control: The sliding gate plate adjusts the opening size of the nozzle through the sliding mechanism, thereby controlling the flow of molten steel. This is very important for maintaining a constant and controllable casting process.
- Operational Flexibility: The sliding gate plate allows operators to adjust the molten steel flow rate as needed during the casting process to adapt to different production requirements and conditions.
- Emergency Stop: In an emergency, the sliding gate plate can completely close the flow channel and stop the flow of molten steel, thereby preventing accidents and losses.
HYRE Slide gate plate design and materials
- Refractory materials: Slide gate plates are usually made of high-performance refractory materials such as alumina, zirconia or chrome. These materials must be able to withstand high temperatures and corrosion from molten steel.
- Structural design: The design of the slide gate plate must ensure smooth and precise sliding. The surface of the plate needs to be highly smooth to ensure sealing performance and accurate flow control.
- Size and shape: The size and shape of the slide gate plate vary depending on the specific design of the ladle or tundish. It usually consists of a fixed plate and a sliding plate that interact with each other through a sliding mechanism.
