High Temperatures Fired Slide Plates

Brand: PN-SLH

PN series of slide plates fired at high temperatures show the features of high strength, good erosion resistance and excellent thermal shock resistance. The products are the best choice for large and medium sized ladles and con-casting tundishes. PN series of slide plates fired at high temperatures cover Al2O3-C based, Al2O3-ZrO2-C based and MgO-spinel based, which can meet various needs of different steel grades.
