た事実からも了解されよう。Steel sheets plated with aluminum or aluminum-zinc alloys are most commonly used as surface-treated steel sheets. Despite its superior performance compared to zinc-plated steel sheets, copper strips have not been used in large quantities in a bath of molten aluminum or aluminum-zinc alloy. When continuously immersing and plating, the part where the copper strip enters the bath is sealed with metallic sodium gas to create a strong reducing atmosphere, and the temperature of the copper strip is kept around the bath temperature of the plating solution. In particular, unless the oxidation of the copper strip immediately before it enters the bath and the level of the plating solution that comes into contact with the copper strip is completely prevented, normal plating cannot be achieved. In order to efficiently perform plating by passing the plating metal through a molten bath, it is necessary to use alloys with excellent heat resistance and corrosion resistance in the bath, and structures such as zinc rolls and zinc roll support fittings made of iron-based materials. However, aluminum and aluminum-zinc alloys in a molten state corrode the above-mentioned structures to a much higher degree than molten zinc, so it is difficult to use the structures by placing them in a bath for a long period of time. In order to do this, a special material had to be used for the material.For example, 20 pieces of low carbon steel plate were placed in an aluminum-zinc alloy melt containing 75% aluminum and 25% zinc.
This can be understood from the fact that when an immersion test was conducted at a temperature of 0.8C to 750C, the steel plate eroded in about 2 hours and a hole with a diameter of about 50m was formed.

示す。The structure will be explained based on one implementation shown in FIG. 1. A bottomless frame d with a lower part C immersed in the molten lead bath a is installed near the liquid level of the molten lead bath a. An aluminum melt or an aluminum-zinc alloy melt e is floating on the molten lead a' in the frame d, and the steel strip A to be plated, whose surface has been cleaned, is placed in the molten lead bath outside the frame d. Enter the molten lead bath a from above a, change direction with the zinc roll f in the molten lead bath a, pass through the frame d, and become the aluminum melt or aluminum-zinc alloy melt. It is designed so that it can pass through the air and exit into the outside air. The frame d is lined with molten aluminum or molten aluminum-zinc alloy, high alumina ceramic, carbon, etc., which are difficult to consume. Note that the middle part of the figure shows the heating device mounting part.

に引揚るようにする。Since this embodiment has a diagonal-like configuration, if we take the example of plating aluminum or aluminum-zinc alloy on a copper strip produced by cold rolling, first the surface of the steel strip is plated. Preliminary step 7: Remove oil and fat such as rolling oil with an alkaline cleaning solution, pickle with hydrochloric acid, etc. to remove oxides on the surface of the copper strip, and immerse it in an aqueous solution of ammonium chloride, zinc chloride, etc. The surface of the copper strip after pickling is prevented from oxidation by the lux treatment, and after preheating, the copper strip is introduced into the molten lead bath a from above the molten lead bath a outside the frame d, as shown in Fig. 1. , the direction is changed by the zinc roll f't f in the molten lead bath a, and the aluminum melt or the aluminum-zinc alloy melt e floats in the frame d. so that it can be brought out into the open air.

きる。This invention has a structure like an upward slope, and since the copper strip enters the molten metal bath from the lead molten side, there is no need to consider the atmosphere on the surface of the plating bath. Furthermore, since the zinc roll is placed in a lead bath, it can be made of iron-based material, and steel sheets or aluminum galvanized steel sheets can be produced in large quantities quickly and with simple equipment.

種加工性の試験には好結果を示している。Also, the molten liquid of aluminum or aluminum-zinc alloy, which is the plating metal, always floats on the lead bath, and the bottom of the aluminum or aluminum-zinc bath is always in contact with the lead bath. Inside is 2 chill 4% lead.
The lead component contained in this product has shown good results in product corrosion resistance and various processability tests.

させるととができる。Adding silicon to the plating metal foam described above suppresses the formation of iron-aluminum alloy at the boundary between the copper strip and the plating layer, making it difficult for the plating layer to peel off when the product is processed, and reducing the aluminum content. 75; 70% ~ 901811J
tj') Add 3 to 10 tin to the aluminum-zinc bath. However, although silicon improves the caroe properties of the product, it impairs the corrosion resistance, so it is better to use a small amount as long as it does not affect the caroe properties. Note that when the elements MgtCa, Be, Ti, and Cu are added to the aluminum bath or aluminum-zinc bath in addition to silicon, corrosion resistance, workability, paintability, etc. can be improved.
