The said method is desirable beunder heat and pressure. To this end the strip cause it affords economical procedure by which of ferrous coated steel may, in its continuous films or layers of any desired thickness may be movement, be led though a furnace and there deposited upon the steel strip by relatively simple subjected to a suitably high temperature, as for apparatus, the deposit having smooth surfaces example 800-900 F., preferably in a non-oxidizfree of pinholes. Briefly, the method is to circuing atmosphere. late within a single tank-like cell an acid solunace, the hot steel strip may be led to the hot tion of ferrous salt, the solution being subjected rolls between webs of aluminum foil or sheet, for to electrolysis between the steel strip as a bonding under high pressure, customary with the cathode and a suitable anode, such as a cost reduction of aluminum plate into sheet. The
composite structure leaving the hot roll will be reduced in thickness,and it can be further rolled to reduce thickness, coiled for further heat treatment, or cut into sheets for use or further heat treatment.
As an alternative, the steel strip leaving the ferrous plating, washing and drying stations may then receive the aluminum sheet or foil webs fed into surface contact with the electro-deposited surfaces of the steel stripand under substantial roll pressure for a light bond thereto. The com posite structure in its continued movement may then be led through the furnace for heating, followed by hot rolling and treatment as before stated.
In a still applicable method the ferrous plated steel strip carrying the cladding sheets a foil, lightly bonded to the strip by roll pressure, may be loosely coiled by the usual coiling basket devices, and then transferred to the furnace for heating. Thus a stock of aluminum surfaced steel strip coils may be heated and made ready for the hot rolls. v
In the use of the term aluminum herein, I include alloys which are predominantly aluminum.
It will be understood that the method is capable of wide variation in details. For example in the case of some types of aluminum alloy sheets, it may be desirable to first coat the alloy'with commercially pure aluminum, so that the contacting faces in cladding the steel strip will be elec trolytic iron and relatively soft aluminum, both particularly compatible with their carriers and with themselves. The method is obviously applicable to the aluminum cladding of steel plates and cut sheets in addition to strip.
The method also is applicable to the provision of a bonding film consisting of electrolytic iron directly upon sheets of foil of aluminum or aluminum alloys to be employed as cladding material. Either one or both faces of aluminum foil or sheet web may be plated with the electrolytic iron. In the first case the thus plated aluminum or aluminum alloy sheet or foil may be employed as the cladding material, that face carrying electrolytic iron being placed opposite to the steel strip or plate in the bonding operations. In the second case, where both faces of the aluminum or alloy foil or web is coated it will serve as'a bonding medium to be placed intermediate the steel and the aluminum or alloy cladding, as will be understood without further explanation.
As a still further variation a stripped web of electrolytic iron, obtained by the method of the Whitfield and Sheshunofl patent bond referred to may be used as the bonding material between the steel strip and the aluminum or aluminum alloy cladding.
Having described my invention, what I claim and desire to secure by Letters Patent, is as follows:
1. A method of continuously cladding steel strip with aluminum, which consists in feeding steel strip through an electrolytic iron plating bath and depositingrelatively pure electrolytic iron thereon, continuing the movement of the strip through dryingand heating zones, wherein the strip is raised to a temperature of from 800 to 900 F., and bringing aluminum in web form into face association with the steel strip followed by the step of hot rolling under reduction pressure and below the fusing temperature of aluminum.
2. The method of bonding sheet aluminum material to steel which comprises providing the steel with a surface of electro-deposited iron, placing a sheet of aluminum material against the electrodeposited iron surface of the steel, heating said assembly in a non-oxidizing atmosphere to a temperature of from 800 to 900 F., a temperature below the melting point of the sheet aluminum, and applying roller pressure to bond the sheet aluminum material to the steel.
