摘要： PURPOSE:To prevent the denting and scuffing of a metallic strip by providing plural deflector rolls directly before a position where the strip is transferred to a horizontal path from a vertical path to deflect the strip. CONSTITUTION:An intermediate deflector roll 3 is provided between the lower throat 1 and the lower deflector roll 2 in the vertical direct-fired heating furnace. A metallic strip 4 is deflected in the opposite direction to the traveling of the horizontal path immediately before the strip 4 is transferred to the horizontal path by the deflector roll 3. Consequently, the tension exerted on the strip 4 is increased, the strip is not brought into contact with the wall of the throat 1 when being passed through the throat, and the strip 4 is not scuffed. Furthermore, a pan 5 is provided on the horizontal path side of the deflector roll 3 to collect the broken brick pieces 6, etc., falling from the upper part of the furnace, and the denting of the strip 4 by the deflector roll 2, etc., is prevented.

摘要： PURPOSE:To economize energy and to eliminate pollution by burning the solvent generated in a baking furnace of a continuous color line by using an iron ore catalyst, returning the combustion gas thereof to said baking furnace and utilizing cyclically said gas for heating a strip. CONSTITUTION:The solvent generated in the baking furnace for the painted strip 1 in the color line is burned by using the iron ore catalyst 5. Said combustion gas is returned to said baking furnace and is cyclically utilized for heating the strip 1. Part of said combustion gas is passed through a hot water boiler 7 to recover the hot water and is then released. Since gas heating burners are hardly used in this method, the energy consumption is decreased to

摘要： PURPOSE:To reduce the size of dehumidifying and cooling installations and perform titled rust preventing and cooling by containing annealed coils in respective chambers, supplying a small amount of dehumidifying air into the respective chambers and properly operating the fan cooler units provided in each chamber. CONSTITUTION:Cold rolled coils 6 having undergone annealing are changed into respective chambers 71-7n through their shutters 70. Thence, in the chambers 71- 7n, respective fans 14 and cooler units 15 are operated and the dehumidifying air fed from air feed ducts 51-5n is circulated in the chambers and is blown to the coils 6 from nozzles 16. The air elevated of temp. by the coils 6 is again cooled by the units 15, thus the chamber inside is controlled to prescribed temps., and the respective coils 6 are rust prevented and cooled. After the completion of the cooling of the coils 6, the operations of the fans 14 and the units 15 are stopped and only the dehumidifying air is supplied in a small mount into the chambers 71-7n through the ducts 51-5n, thence the coils 6 are stocked and rust prevented.
摘要翻译：目的：为了减小除湿冷却装置的尺寸，通过在各室内容纳退火线圈，进行标题化的防锈冷却，向各室供给少量除湿空气，适当地操作设置在各室内的风扇冷却器单元。构成：已经经过退火的冷轧卷材6通过其快门70改变成相应的室71-7n。然后，在室71至7n中，相应的风扇14和冷却器单元15被操作，并且从供气管51供应的除湿空气 -5n在腔室中循环，并从喷嘴16吹送到线圈6。线圈6再次由单元15冷却，因此将室内控制到规定的温度，并且各个线圈6被防锈和冷却。在完成线圈6的冷却完成之后，停止风扇14和单元15的操作，并且只有除湿空气通过管道51-5n以小的安装力供应到腔室71-7n中，然后线圈 6储存并防锈。

摘要： PURPOSE:To prevent the electrolysis current density from being lowered by continuously flowing an electrolytic washing liquid between a surface of a running strip and a continuous flat surface of an opposed electrode mutually arranged in parallel to a running direction of a strip to prevent a gas from being accumulated due to electrolysis. CONSTITUTION:A strip 10 running through a washing liquid 8 supported by a pair of support rollers 9 in paralle or in an almost parallel condition is present in an electrolytic tank 7 and a pair of opposed electrodes 11 having a continuous flat surface is provided to an upper and a lower surface of the strip at a predetermined distance. Herein, a washing liquid is continuously flowed between the strip and opposed electrodes from a washing liquid injecting apparatus 12 equipped with a slit 12a for injecting the washing liquid and a liquid supply passage 12b to a running direction of the strip. Thereby, the gas generated by electrolysis is exhausted from a space between the strip and opposed electrodes to the outside.

摘要： PURPOSE:To heat and anneal the entire part of coils uniformly with good thermal efficiency by disposing radiant tubes on the top and side surfaces of the coils, and heating the coil through circulation of radiant heat and high temp. atmosphere gases in a box type annealing furnace for annealing coils. CONSTITUTION:Radiant tubes 4 are disposed to the ceiling of annealing furnace 1, and baffle plates 5 are erected vertically on both sides of the furnace to constitute circulating flow passages 6 for the atmosphere gas in the furnace. Radiant tubes 7 and fans 8 are beforehand provided in these passages 6. The coils A put into the furnace are heated at the top surfaces by the radiation heat of the radiant tubes 4; at the same time, the high temp. atmosphere gas in the furnace flows through the passages 6, is heated by the tubes 7, is flowed through a plenum chamber B by the fans and circulates by passing the insides of the coils from the bottom surfaces of the coils A, and therefore the inside of the coil is heated quickly, and the coils A are heated and annealed uniformly in a short time.
