CONSTITUTION:Preheating rolls arranged at inlet side of the heating furnace 2 are constituted with plural low temp. rolls 14 an plural high temp. rolls 18. Heating medium recovered by heat exchanging sensible heat of combustion waste gas of the furnace 2 is passed to each roll 14. On the other hand, heating medium heat exchanged with sensible heat of gaseous mixture of combustion waste gas of the furnace 2 and waste gas obtd. by heating said waste gas to a prescribed temp. by heating means is passed to each roll 18. As the result, since temp. of each roll group can be varied corresponding to load variation of the furnace 2 by mixed ratio of combustion waste gas of the furnace 2 and introduced gas and operation of heating means in low temp. rolls group (normal temp. -150 deg.C) and high temp. rolls group (150-450 deg.C) in preheating roll, stable preheating is possible without being affected by load variation of the furnace 2.

摘要： PURPOSE:To replace a heater easily and to uniform the temperature distribution in the axial direction of a roll by providing a pocket at the central axis of the roll to allow to open to the atmosphere, housing a low melting point metal and a heater and sealing a heating medium of a specific condition around the pocket. CONSTITUTION:In an inner tube 5 at the center of a hollow roll 1, a heater 2 and a Wood's metal as a low melting point metal are housed and closed by a lid 6 to form a pocket. As a result, the heater 2 melts the metal 4 and heats the roll in a good heat transport efficiency, while the heater can be replaced regardless of a heating medium 3. In a space between the tube 5 and the roll 1, potassium is sealed as a heating medium 3. The heating medium 3 is set to wet at least a part of the inner tube 5, and the vapor molar fraction in a gaseous phase is made 80% or higher in the service temperature scope. Consequently, the temperature can be uniformed without disturbing the condensation of the heating medium vapor to the lower temperature side wall surface of the roll.

摘要： PURPOSE:To seal cooling water regardless of the size of a metallic strip and to maintain the cooling water in a full state by specifically providing baffle plates to guides of the cooling water chamber of a water jet type device. CONSTITUTION:Plural pieces of the baffle plates 10 which project to the metallic strip 1 side and extend in the traveling and moving direction of the metallic strip are provided in the transverse direction of the strip 1 to the guides 7 of the cooling water chamber D. The cooling water is ejected from slit nozzles 6 in the form of slit-like jets 5 to the strip 1 surface. On the other hand, the sealing water 9 injected from sealing water nozzles 8 toward the inside of the guides 7, 7 acts in the direction where the water does not flow from the outlet in the cooling water chamber D. The cooling water, therefore, tends to flow out on the strip 1 in the side end direction thereof, but the baffle plates 10 prevent such outflow by the effect of passing the water repeatedly through the space enclosed by the top ends of the baffle plates and the surface of the strip 1. As a result, the cooling area of the strip 1 is increased and the cooling performance is considerably increased.

摘要： PURPOSE:To cool a roll so as to have a uniform temp. distribution in an axial direction and to prevent the deformation of a roll sleeve by passing cooling water to plural cooling water passages parallel with the axial line to the inside of the roll near the surface thereof, sealing the cooling water into the cooling water passages and executing rolling. CONSTITUTION:A circulation pump 23 is operated to feed the cooling water in to the cooling water passages 20 in the roll, thereby cooling the roll body. Shutoff valves 25 and 28 of water feed and drain pipes 22 and 27 are then closed to confine the cooling water into the passages 20 and thereafter the rolling is executed. The valves 25 and 28 are opened to feed the cooling water into the cooling water passages 20 in the roll and to circulate the water upon completion of the rolling or upon ending of one pass. The roll is thereby cooled. The cooling water is sealed into the passages 20 on the inside of roll sleeve 7 in the stage of rolling, then the cooling water which is incompressible fluid transmits and supports the load during rolling to the core part of the roll inside, thereby preventing the deformation of the roll sleeve. The thickness of the roll sleeve is thus decreased and the cooling effect of the inside of the roll is improved without making inferior the shape of the metallic plate.

摘要： PURPOSE:To prevent quality deterioration and trouble caused by the flutter of a plate by arranging a pressure dropping device as well as forming the outer periphery of at least one roll out of a pair of upper and lower seal rolls into a soft elastic body, so as to make a pinch roll capable of reliably pinching a metallic strip in passing. CONSTITUTION:Rubber linings are applied to a seal roll pair, and an upper seal roll 1 is raised by a raising actuator 3, and a threading bar and a metallic strip 5 are guided by a threading guide 4. When the upper seal roll 1 is made under low pressure, the strip 5 is pinched by both rolls 1, 2, and the passing range of jet air flow is only a seal roll clearance part 7. Moreover, when pressure dropping force of the raising actuator 3 of the upper seal roll 1 is increased, the jet air flow is further decreased. Thereby, in a flat path, trouble or quality deterioration caused by the flutter can be prevented.

摘要： PURPOSE:To provide a titled device for preventing thermal deformation which prevents the meandering and heat buckle of a strip to be generated by the nonuniform thermal deformation of a roll to be wound around with the strip in the axial direction thereof by constituting the device in such a manner that gas is blown to the part of the roll having no contact with the strip to diminish the temp. difference along the axial direction of the roll. CONSTITUTION:The gas is blown from gas blow holes 8 of a gas jet plenum 7 provided to face the roll 6 toward the part of the roll 6 where the roll does not contact the strip 3 during passage. In this case, the cooling gas is injected when the strip 3 is lower in temp. than the roll 6 and the heating as is injected when the strip 3 is higher in temp. than the roll 6. The uniform temp. of the roll 6 is thus maintained along the axial direction thereof even during the transfer of the strip 3 in winding the same around the roll. The nonuniform thermal deformation of the roll 6 by the temp. difference is thereby prevented. Since the nonuniform thermal deformation of the roll 6 is prevented, the meandering and heat buckle of the strip 3 are prevented.

摘要： PROBLEM TO BE SOLVED: To provide a hot dip metal coating method and a hot dip metal coating device which can stably and continuously manufacture a hot dip metal coated metallic strip having plating quality uniform in a metallic strip width direction. SOLUTION: When the metallic strip 10 moving upward is made enter a hot dip metal coating bath from a lower part thereof and the metallic strip is wated by delivering and supplying molten metal to the metallic strip while holding the hot dip metal coating bath by applying an alternating magnetic field thereto, the molten metal is delivered and supplied by changing at least one among composition, temperature and flow velocity in the metallic strip width direction so that forming or suppression of an alloy layer at a boundary between a metallic strip base and a hot dip metal coating layer is uniform in a width direction of the metallic strip. Temp. of the molten metal delivered and supplied to both edge parts in the width direction thereof is made lower than temp. of the molten metal delivered and supplied to a central part in the width direction. Otherwise, concentration of a component suppressing the alloy layer at the boundary between the metallic strip base and the hot dip metal coating layer is made higher at the both edge parts in the width direction than the concentration of the concentration at the central part in the width direction. Otherwise,flow rate of the molten metal delivered and supplied to both edge parts in the width direction is preferably made faster than flow rate thereof delivered and supplied to the central part in the width direction.
