摘要:
This invention relates to a continuously treating line for a steel band, having a heating furnace by directly flaming. For heating the steel band with causing reduction, the heating furnace of directly flaming system is provided with a plurality of heating burners of reduction system which may form non-equilibrium range of the air and the fuel in a flame, that is, a reduction range, wherein the heating burners are positioned at predetermined arrangement with respect to the steel band and at a certain pitch predetermined in relation with an inner diameter of the burner in a line running direction.The treating line has said heating furnace constructed as mentioned above and a subsequent atmosphere furnace, and said atmosphere furnace may be provided with a sealing chamber having various means for avoiding invasion of the outer air.The line has, in order, a pre-heating furnace, said heating furnace and an indirectly heating furnace, and it may be furnished with intermediate chambers between respective furnaces for preventing the furnace gas from moving, and further may be furnished with an after-burning chamber for perfectly burning a combustion exhaust gas to be supplied to the pre-heating chamber.

摘要:
The present invention relates to a method for producing high silicon steel strip in a continuous treatment line through chemical vapor deposition (called "CVD" hereinafter), wherein the steel strip is subjected continuously to siliconization at temperatures between 1023.degree. and 1200.degree. C. by CVD in a non-oxidizing gas atmosphere containing SiCl.sub.4 between 5% and 35% in molar fraction. Subsequently a diffusion treatment is performed in a non-oxidizing gas atmosphere not containing SICl.sub.4 for diffusing Si uniformly throughout the steel strip, which is then cooled and coiled. If required, the steel strip may be coated with an insolating film and subjected to a baking treatment, before cooling and coiling.

In an electrolytic treating on a strip of metal, namely electroplating, electrolytic degreasing or any other electrolytic treatment on a strip of metal, in order to fludify the liquid between the plane parallel plate electrodes immersed inside the tank or between the plane parallel electrodes and the metal strip passed therebetween by jetting the liquid from the nozzles into the tank, a plane dummy plate or plates are arranged between the nozzles and the plane parallel plate electrodes to adjoin the electrodes and extend in the direction of the nozzles in the same planes as the electrodes to thereby prevent the damping of the jet flow velocity. Moreover, the plane parallel plate electrodes have their edges on the nozzle side arranged in positions at which the half-value width of the nozzle jets from the nozzles overlap each other to thereby ensure a uniform distribution of the jet flow velocity.
