摘要： PROBLEM TO BE SOLVED: To provide a heating furnace which is not complicated in structure but capable of surely reducing the skid mark, and its operation method. SOLUTION: The position of a fixed skid beam Sf and a movable skid beam Sm is shifted in the width direction of a heating furnace 10 in the extraction side zone Z of the furnace. In the extraction side zone Z, alternating combustion burners 1 to periodically repeat the combustion and the non-combustion are provided on a side wall of the heating furnace parallel to a skid beam of a lower combustion zone. Because the stirring of the combustion gas is promoted in the region within the heating furnace 10 by the alternating combustion burners 1, the heat transfer is not interfered by the skid beam S. The skid marks on the material to be heated are reduced in number thereby.

摘要： PROBLEM TO BE SOLVED: To accurately control the thickness of a coating film formed by continuous coating. SOLUTION: From a coating film thickness model formula for using flow rates of paint 9 passing between a pickup roll 3 and a metering roll 4, the pickup roll 3 and an applicator roll 5, and the applicator roll 5 and a metal belt 8 to obtain coating film thickness, a gap between the pickup roll 3 and the metering roll 4 suitable for forming a coating film made to have object coating film thickness is obtained. From the obtained gap, shearing velocity of the paint 9 between the pickup roll 3 and the metering roll 4 is obtained. From the obtained shearing velocity, viscosity of the paint 9 passing between the pickup roll 3 and the metering roll 4 is obtained. And based on a lubricating fluid theory, from the obtained viscosity of the paint 9, a pressing load between the pickup roll 3 and the metering roll 4 is obtained. By using the pressing load obtained based on the lubricating fluid theory, continuous coating is performed.

摘要： PROBLEM TO BE SOLVED: To efficiently reduce the oxide on the surface of a metallic plate in a short time without using the large scale of device by blowing plasma of reducing gas induced with microwave under the atmospheric pressure to a metallic plate continuously passed in a heating furnace. SOLUTION: Gaseous nitrogen is supplied into a plasma generating chamber 7 from a gas supplying source 9 of a continuous treating device to replace the air in the chamber 7. Successively, the power source of a microwave generating source 6 is put on and the material 8 inducing the generation of the plasma is heated and also, the reducing gas is supplied into the chamber 7 from the gas supplying source 9 by changing over a valve to form the plasma. The generated plasma is fed into a treating chamber through a plasma flowing passage 5 and the steel plate 1 continuously passed, is heated and the oxide on the surface of the steel plate 1 is reduced. The plasma blown to the steel plate 1 and the gas after reacting the reducing gas with the oxide, are desirable so as to flow on a carry-in side of the steel plate 1.

摘要： PROBLEM TO BE SOLVED: To reduce the fuel unit requirement, and improve the heat recovery by a method wherein the height of a furnace is set by a range including the region wherein characteristics to reduce the fuel unit requirement by the increase of a radiant heating value due to the thickness of a combustion gas layer, and characteristics to increase the fuel unit requirement due to the increase of a heat loss value accompanying the increase of a furnace wall area, cross. SOLUTION: For furnace height vs fuel consumption characteristics, when the thickness of a fuel gas layer increases, the radiant heat transfer value by the fuel gas layer increases, and the fuel consumption value is reduced in response to the increased portion of the radiant heat transfer value. In the meantime, for furnace height vs fuel consumption characteristics, as a furnace height becomes higher, the furnace wall area increases and a furnace heat loss increases. Therefore, the fuel consumption value to compensate the furnace heat loss portion, increases. Therefore, fuel consumption characteristics by the furnace height can be obtained by the two furnace height vs fuel consumption characteristics. As a result, the range wherein the fuel unit requirement becomes minimum, can be obtained, and the range becomes a suitable furnace height range for the furnace height.
