A method of molten metal plating, comprising the steps of: bringing a travelling steel strip into contact with a revolving roll; applying a molten metal on the roll through a nozzle disposed near the roll; and transferring the applied molten metal from the roll to the steel strip by the revolution of the roll. An apparatus for molten metal plating, comprising: a coating roll capable of being brought into contact with a travelling steel strip; a nozzle disposed near the roll for applying a molten metal on the roll; and a source for supplying a molten metal to the nozzle.

Apparatus for molten metal plating

A sheet steel easy open can lid made by a resin-laminated sheet steel and not requiring repair coating of the inner and outer surfaces thereof, wherein use is made of a sheet steel laminated with a resin such as polyester and a tear-along groove, having as its main constituent element at the peripheral edge of the opening piece a thin portion having the specified minimum thickness is formed by composite cold-forming. The part or substantially all of this can lid can be easily opened by hand.

A steel sheet for making cans carrying a layer of a thermoplastic resin having a thickness of 3 to 100 microns on at least one surface thereof which, when shaped into a can, will define its inner surface, and a foil of aluminum or an aluminum alloy having a thickness of 5 to 100 microns on the resin layer. Also disclosed is a can for holding a drink which is formed from such a steel sheet, and which has a layer of a thermosetting resin on the foil. A method of making any such can is also disclosed.

Steel sheet for making cans, cans and a method making cans

Coated steel sheet of high corrosion resistance comprises a sheet of steel containing not more than 0.1% by weight of carbon, 0.005 to 0.08% by weight of soluble aluminum and 0.2 to 20% by weight of chromium, the balance being iron and unavoidable impurities. The steel carries a nickel or nickel alloy layer formed on at least one surface thereof and having a thickness of 0.001 to 1.5 microns and a layer of tin formed on the nickel or nickel alloy layer and having a thickness of at least 0.05 micron. A method of producing it is also disclosed.

Tinned steel sheet having a high degree of corrosion resistance and a

A complex film is formed on a steel sheet by coating thereto an aqueous solution of ammonium phosphate, ammonium molybdate, nickel aceptate, etc., heating the same and further coating a lubrication oil containing an animal or vegetable oil or fat or a mineral oil with a high molecular compound and a higher fatty acid, whereby a steel sheet showing excellent lubricity in ironing is given. The effect can be improved by adding cobalt, nickel, chrome salts to the aqueous solutions.

Method for the manufacture of a steel sheet adapted for use in ironing

A method for treating the surface of a steel sheet adapted for use in making a container or can is provided. A nickel-defused layer is first formed while recrystallization annealing is conducted, upon which layer a film of chromium is plated after temper rolling or double cold rolling. The good lacquer adhesion property of the Cr layer and the good formability of the Ni layer will synergetically act so as to give an excellent anti-corrosion property to a material for cans.

Method for the manufacture of a steel sheet having a Ni-diffused base

A steel sheet having a Ni or Cu base plating layer and a Sn upper plating layer characterized by the absence of any alloy layer intervening therebetween is subjected to an ironing operation with the thickness of the plating being relatively small. The internal surface of the can thus formed is provided with an organic coating for packing foodstuffs including effervescent beverages.
