Production Introduction

    This product uses synthesis process and is obtained from balling and burning in high temperature, which will form a solid and complete sintered layer in high temperature. Good in hot patching nature, it is widely used in the hot patching of the bottom and slope of UHP, HP, RP and DC electric stove and open-hearth furnace.
