Furnace repairing bricks use fused magnesia as main materials and environment-friendly organic compounds as binders, adding a certain amount of sintering aider, and then produced by mixing and high pressure forming.

　　Furnace repairing bricks for converters belong to MgO-C fettling materials, which combined with various other bulk materials, adhering to each other under high temperature after repaired, with the result that furnace repairing bricks for converter have a good performance of sintering and corrosion resistance.

　　Furnace repairing bricks are mainly used for converters what the working surface of converter is magnesia carbon bricks and magnesia dolomite bricks hot repairing.

　　Furnace repairing bricks can be used as subsidy bricks or hand feeding mass during the construction, of which quantity and reline mode can be determined by actual erosion area and corrosion depth of lining bricks.

　　There are some differences between using performance and sintering time according to the amount used of lining bricks. Generally sintering time is no more than 30 minutes, while using time between 25 and 45 hours.
