Abstract
The invention provides a superwide beam structure for a furnace door, which comprises section steel, a plurality of female bricks and a plurality of male bricks. The section steel is arranged on the upper part of the furnace door, and is uniformly distributed with bolt mounting holes; a hanger bolt is respectively arranged on each female brick and each male brick; each female brick and each male brick are spliced in a staggered way and then fixed on the section steel in a hanging way; the joint of adjacent female brick and male brick has star-shaped indentation; the hanger bolts on the female bricks and male bricks are inserted into the bolt mounting holes on the section steel; and the space between the hanger bolts is consistent with the pitch of the bolt mounting holes on the section steel so as to form an integral beam. Because each prefabricated brick has small dimension and is independent, and the joint of two adjacent prefabricated bricks is in a star shape, the expansion caused by heating of each brick is small and cannot accumulate the expansion stress so as to eliminate the phenomenon of cracking of the beam and reduce direct short-circuit of hot air; and even if individual prefabricated bricks have problems in use, two adjacent bricks are required to be replaced only.
