Product Introduction

The design and placement of the slag plate in the tundish can change the flow state of the steel liquid in the tundish, effectively promote the floating of harmful impurities in the steel liquid, thereby enhancing the functional effect of the tundish to purify the steel liquid; the impact plate and the wall plate can Effectively ensure the safety of the tundish during use and can significantly increase its service life. The slag retaining plate, impact plate, wall plate and nozzle brick series products developed by our company have the characteristics of good slag resistance, high temperature strength and long service life.
