摘要： PURPOSE:To smoothly supply raw materials with an approximately uniform distribution by respectively and specifically disposing openings in the lower parts of an outer cylinder which is supported inclinedly by a vibrating device and an inner cylinder which is rotatably supported therein and receives the raw materials. CONSTITUTION:This supplying device 20 has double cylindrical structures consisting of the outer cylinder 21 and inner cylinder 22 having the downward slit-shaped opening 23B and longitudinal opening 24B respectively in the lower parts ans is supported with inclination from horizontal at an angle theta. The entire part of the device 20 is vibrated by the vibrating device 28 at the time of accepting the pellets 12 supplied from a hopper 10 via the opening 23A, 24A of the outer cylinder 21 and the inner cylinder 22. As a result, the pellets 12 from the opening 24A are rolled and the lower positions in the inner cylinder 22 are successively filled with these pellets and, therefore, the pellets are distributed approximately uniformly in the longitudinal direction. Next, the opening 24B aligns to the opening 23B when the inner cylinder 22 is rotated about 90 deg. and, therefore, the pellets 12 around the opening 24B fall to a lower basket by passing the opening 23B. At this time, the distribution of the pellets 12 around the opening 24B is uniform and, therefore, the falling distribution into the basket is made approximately uniform as well.

摘要： PURPOSE:To safely and efficiently exchange consumed soluble anodes in a plating tank by connecting an anode exchange truck to the opening in the side wall of the plating tank, transferring the anodes into an exchange case in the truck and fitting new anodes. CONSTITUTION:When soluble anodes 6a, 6b consumed by use in the plating of a steel strip 1 in a plating tank 2 are exchanged, the level of a plating soln. 3 is first lowered to below the opening 10 in the side wall of the tank 2 and an anode exchange truck 12 having wheels 13 is connected to the opening 10. A gate 11 is opened to allow the tank 2 to communicate with the truck 12 and the consumed anodes 6a, 6b are pulled out by sliding on electrifying bars 7a, 7b with pusher bars (not shown) and set on rails 14a, 14b in an exchange case 16 in the truck 12. The case 16 contg. the anodes 6a, 6b is moved on rails 18 through sliding members 17 and new anodes in other exchange case (not shown) in the truck 12 are fitted on the bars 7a, 7b with the pusher bars.

摘要： PURPOSE:To improve the corrosion resistance in the long continuous run in the chloride-based fused-salt electrolysis plating by forming a porous panel opposed to the cathode of a housing constituting the title anode chamber with an insulating material. CONSTITUTION:A powdery or pelletized metallic body 22 as the anode metal is packed in the housing 24, and opposed to a steel body 10 constituting the cathode. The outermost face of the housing 24 constituting the opposing face is formed by a porous panel made of an appropriate metal such as mild steel, Ni, or an Ni-based alloy, and coated with an insulating material or a lining 30. For example, the coat is provided by the thermal spraying of ceramics. A screen 28 is furnished on the opposite side of the panel 26. Since the extent of corrosion varies with the composition, temp., etc., of the fused-salt plating bath, the kind and thickness of the coated insulating material 30 can be appropriately selected as required.

摘要： PURPOSE:To stabilize the quality of a plated film by specifying the drying and preheating conditions of a steel sheet when wet pretreatment is applied and fused-salt electrolysis plating is applied to the steel sheet deposited with a water film. CONSTITUTION:A band steel 2 from a recoiler 1 is continuously sent to a drying chamber 7 through a degreasing vessel 3, a water washing vessel 4, a pickling vessel 5, and a water washing vessel 6, heated, and dried. The band steel 2 is introduced into a preheating stage, heated and dried in an inert atmosphere 9 isolated from the outside by a seal roll 8, activated, and plated by fused-salt electrolysis. In this case, the drying and preheating in the atmosphere are carried out in conformity with the equation when the temp. of the band sheet 2, namely the surface temp. of the steel, is controlled to >100 deg.C. In the equation, Tm is the maximum allowable temp. ( deg.C) of the steel in the atmosphere, and R is the mean temp. increasing rate ( deg.C/s) of the steel in the atmosphere in the drying and preheating after water washing. Concretely, R is the average temp. gradient between the temp. in water washing, namely the temp. of washing water, and the maximum allowable temp.

摘要： PURPOSE:To improve the durability of the device and to produce a good plated material by forming at least a part of the surface of the AlCl3-contg. molten-salt electroplating device in contact with the molten-salt plating bath with Al or an Al alloy. CONSTITUTION:A molten-salt plating bath with AlCl3 such as AlCl3-XCl (X is alkali metals) as one component is used to electroplate a substrate metal such as steel sheet with Al or an Al alloy, and the resistance to corrosion and heat is improved. In this molten-salt electroplating device, at least a part of the surface of the device in contact with the bath is formed with Al or an Al alloy or Mn, Ti Mg and their alloy. These materials are used as the sacrificial anode, or further the device can be cathodically protected by an external power source. In this case, the potential of the metallic material in the bath is preferably controlled to -0.2 to +0.5V with respect to the potential of pure Al. Ferritic stainless steel is preferably used as the metallic material of the device.

摘要： PURPOSE:To stably execute a plating treatment without requiring a large amt. of inert gas in a fused salt electrolytic plating cell by providing inert gas rail chambers before and behind the plating cell at the time of plating a metal on the surface of steel products by a fused salt electrolytic plating method. CONSTITUTION:The steel product 22 un-wound from a payoff reel 21 is welded to the succeeding end of the preceding steel product by a welding machine 23 and is then sent via a looper 24 to a pretreating device 25 where the steel product is subjected to pretreatments, such as defatting, pickling and preheating. The steel product then enters a fused salt electrolytic plating bath 31 in the plating cell 26, where the steel product is energized with an anode column 12 and the metal such as Al, is plated on the surface of the steel product 22 as a cathode by the fused salt electrolytic plating method. This steel product is subjected to a post treating device 27 for washing, drying, etc., a looper 28 and a cutter 29 and is taken up on a tension reel 30. The sealing chambers 33, 34 maintained with the inert gaseous nitrogen likewise at a positive pressure are provided before and behind the plating cell 26 of the inert gaseous atmosphere of nitrogen, etc., by which the inside of the plating cell 26 is maintained always at the inert atmosphere by the nitrogen with the consumption of just a small amt. of the gaseous nitrogen.
