PURPOSE: A strip guide device of an annealing furnace is provided to prevent damage to the surface of an annealing furnace and reduce the internal heat loss of the furnace. CONSTITUTION: A strip guide device of an annealing furnace comprises a pair of mineral rolls(12,13) and upper and lower strip guide sealing units(20,50). The mineral rolls are arranged on the top and bottom of an annealing furnace and guide the transfer of strip. The upper and lower strip guide sealing units guides the transfer of strip to the pair of mineral rolls, respectively. The upper strip guide sealing unit comprises first and second idle rollers(21,22), a first belt(24), a first heat dissipation curtain(25), and a first drive cylinder(30). The first belt is connected to the first and second idle rollers and an upper sealing and pressing roller(23) and reciprocated up and down. The first drive cylinder drives the first belt and the first heat dissipation curtain. The lower strip guide sealing unit comprises third and fourth idle rollers(51,52), a second belt(54), a second heat dissipation curtain(55), and a second drive cylinder(40). The second belt is connected to the third and fourth idle rollers and a lower sealing and pressing roller(53) and reciprocated up and down. The second driver cylinder drives the second belt and the second heat dissipation curtain. |
