[0002] The formal name of the blind plate is flange cover, and some are also called blind flange or pipe plug. It is a flange without a hole in the middle, which is used to seal the pipe opening. Its function is the same as that of the head and pipe cap, except that the blind plate seal is a detachable sealing device, and the head seal is not intended to be opened again. Refractory materials with alumina and carbon as the main components are called aluminum-carbon refractories. Aluminum-carbon refractories have excellent slag resistance and thermal shock resistance, can withstand high temperatures, do not react with molten steel or alloys, and have strong slag resistance.

[0003] In steel production, blind plates are usually required to seal pipe openings. However, in such blind plate structures, the blind plate covers are fixed sealing structures.
