これを圧延してクラツド材を得る方法である。(Prior Art) Conventionally, a wide variety of methods have been put into practical use for manufacturing aluminum clad steel sheets. Typical manufacturing methods that are widely used industrially include rolling methods, explosion welding methods, overlay-rolling methods, and casting methods. The explosion welding method is a method to obtain a clad steel plate by crimping the base material and the composite material using the explosive energy of explosives.In this case, it is possible to obtain a fairly high bonding performance, but the cost is high. Become. The overlay-rolling method involves pouring molten metal, which will become the base material, into a mold with a matching material suspended at the surface of the slab, which will be the base material, to produce a laminated casting.
This method is used to obtain a clad material by rolling this material.

開示されている。From these, the properties of the material used as the laminating material, the manufacturing cost,
The most preferable method is selected from the viewpoint of mass production, etc., but in the case of clad steel sheets made of thin steel sheets and aluminum sheets, the rolling method is used from the viewpoints of difficulty in forming intermetallic compounds, manufacturing cost, mass productivity, etc. 6. In the rolling method, conventionally, the joining surfaces of steel plates and aluminum plates were sufficiently cleaned, then heated to high temperature and bonded by one pass of rolling under heavy pressure, and then the joint surfaces were bonded with the aim of softening them. Annealing is carried out using Furthermore, as a method aimed at rolling joining at a relatively low rolling reduction rate, a method has been disclosed in which aluminum or aluminum alloy plates are crimped using steel plates that have been hot-dipped with aluminum (Japanese Unexamined Patent Publication No. 55-68195). There is.

ルミニウムクラッド材を製造することが困難であった。(Problems to be Solved by the Invention) However, the above-mentioned method of joining at a high rolling reduction ratio of the l-bath requires a powerful rolling mill, which poses a problem of increasing the size of the equipment. In addition, because the amount of processing is large, the steel plate is severely damaged, pressure hardening occurs, joint rabbets, and waviness at the interface (variation in thickness composition ratio between M treatment and aluminum plate) 2. Thin-walled? However, in order to obtain a soft crat material using the same method, it is necessary to perform a softening annealing after joining, but it is difficult to handle and use the steel plate. At the heating temperature, a brittle Fe-AQ intermetallic compound with inferior bipolar properties is likely to be formed at the interface between the aluminum layer and the steel sheet. This means that it requires However-)
It was difficult to obtain a soft clad material, and it was difficult to produce an aluminum clad material with excellent workability.

あった。On the other hand, the method using hot-dip aluminized steel plate is
Compared to a method using steel plates that have not been pre-aluminum plated, the pressure required for joining may be smaller, and in this respect the effect of aluminum plating at LJ can be recognized. However, hot-dip aluminized steel sheets produce brittle intermetallic compounds at the interface between the raw steel sheet and the aluminum plating layer, and when processed, peeling tends to occur starting from these F'e-^Q intermetallic compounds. For this reason, it was difficult to obtain aluminum Clara 1, which has excellent workability.

。Therefore, in Japanese Patent Application No. 2-118036, the present inventors used a steel plate that had been pre-vapor-plated with aluminum.
A method for producing an aluminum clad steel plate with excellent workability without Fe-AQ intermetallic compounds in the joint by heating the steel plate to 550°C or less, overlapping aluminum or aluminum alloy plates, and rolling and joining them at a light reduction rate. However, the problem with this manufacturing method is that it requires continuous heating of the heavily aluminum-plated steel strip before rolling, which requires large heating equipment. Furthermore, since the aluminum plated surface is exposed to the atmosphere after heating and until pressure welding, there is a problem in that the aluminum plated surface is oxidized, which impedes bondability.

℃付近からＦ’ ｅ−ＡＱの金属化合物が生成するため
、接合性は逆に悪くなる傾向にある。In both the method of the present invention and the method of heating a steel strip coated with Y/metal evaporation aluminum and joining it to an aluminum strip, the higher the steel strip heating temperature, the better the bondability becomes.
Since a metal compound of F' e-AQ is generated from around .degree. C., bondability tends to deteriorate on the contrary.
したがって、鋼板温度は５５０℃以トに制限される。Therefore, the steel plate temperature is limited to 550°C or higher.

するために、鋼板加熱温度を低くする必要がある。Here, the reason why the steel sheet temperature in the present invention is based on the steel sheet temperature after vapor deposition aluminum plating is as follows. That is, when the aluminum evaporated in a vacuum atmosphere is deposited on the surface of the steel sheet, the temperature of the steel sheet after the evaporation is higher than the heating temperature of the steel sheet due to the heat of condensation of the aluminum 11. However, the intermetallic compound of l”e-AQ suppresses the formation.
To achieve this, it is necessary to lower the steel plate heating temperature.
