[Prior Art] Conventionally, when a titanium clad steel plate is manufactured by hot rolling,
For example, as shown in JP-A-60-18205 and JP-A-60-170586, carbon steel or stainless steel, which is a base material, may be used with Cr, Ni, Cu, and Insert a thin plate or foil such as Mo, put titanium or titanium alloy as a bonding material, fix it with welding, heat it and heat it, but Ti and Fe are very brittle intermetallic compounds at high temperature. Since it is generated, it cannot be welded directly. Zirconium oxide, etc. is used as a separating agent on the surface where the titanium or titanium alloy, which is the composite material, faces each other with the titanium or titanium alloy, which is the composite material, facing inward. The paste consisting of is applied and assembled in a sandwich form to fix the steel base materials together by welding, or one set is used to stack the titanium or titanium alloy as the inner material and stack the steel as the discarded material. Apply a paste made of zirconium oxide, etc. as a separating agent to the surface where the titanium or titanium alloy, which is the base material, and the steel, which is the discard material, come into contact, and assemble it in a semi-sandwich shape. It has been fixed and heated to 600 ℃ to 1000 ℃ and then hot rolled to produce titanium clad steel sheets.

[Problems to be Solved by the Invention] According to the above-described manufacturing method, the titanium or titanium alloy surface which is the laminated material is inside the assembly slab and does not contact the rolling roll, causing rough skin. The rolling compression bonding method is a highly productive manufacturing method, but this rough skin requires maintenance of the surface after manufacturing, which lowers the yield of expensive titanium and titanium or titanium alloy is thin in the case of thin plate manufacturing. Since it cannot be maintained, it has been an obstacle such as not becoming a product or causing a surface breakage during cold rolling.

As a result of various studies based on this idea, stable oxides such as aluminum oxide and zirconium oxide are the most effective for separation after sandwich type or semi-sandwich type production. It has been found that the titanium surface will be roughened as it is because it has no lubricity. Therefore, it is necessary to provide lubricity to this, but it is necessary to have lubricity at the titanium clad manufacturing temperature as high as 600 ° C or higher. It was It was also found that the inclusion of mica, potassium phosphate salt, and potassium titanate salt is effective for imparting lubricity at a high titanium clad production temperature of 600 ° C. or higher.

Next, the limiting conditions of the present invention will be described. The present invention is a sandwich type in which titanium or titanium alloy surface does not become rolling skin because titanium or titanium alloy surface does not become surface rolling roughness when titanium or titanium alloy surface does not become rolling skin when manufacturing titanium clad steel sheet.
It was time for the semi-sandwich type manufacturing method. Manufacturing temperature of hot rolled titanium clad steel plate is generally 600 ℃
Since it is ~ 1000 ° C, it was set to this range. Since titanium is a very active metal, it is easy for them to adhere to each other, and especially when rolling a thin plate with a high reduction ratio, it cannot be separated with an antioxidant such as water glass, so the base of the separating agent is a stable oxide of aluminum oxide. , Zirconium oxide. This ratio is not particularly limited because there is no difference between aluminum oxide and zirconium oxide. As a result of actually hot-rolling and manufacturing titanium clad steel sheets for various substances having a lubricating action, it was found that mica, potassium phosphate, and titanic acid are substances that maintain a lubricating action at the titanium clad steel production temperature and achieve a good titanium surface. Since it was a potassium salt, it was decided to include these alone or in combination. If the content ratio is small, the lubricating effect is exhibited, but if the weight ratio is less than 30%, it is not sufficient. Therefore, the content is determined to be 30% or more. If the weight ratio exceeds 80%, the separability will deteriorate, so 8
It was set to 0% or less. Since there is no difference between mica, potassium phosphate salt and potassium titanate salt, they may be used alone or may be combined in any ratio without any particular limitation.

[Working] Mica, potassium phosphate, potassium titanate 600 ° C
It has a lubricating effect at the above-mentioned high temperature production temperature of titanium clad, and ensures a good surface texture of the titanium surface. Mica, potassium phosphate salt, and potassium titanate salt, alone or in combination, have a total weight ratio of 30% or more 8
The content is 0% or less, and the balance is stable oxides such as aluminum oxide and zirconium oxide, so that separability can be ensured, and titanium or titanium alloy is inside the assembly so that the titanium surface is not a rolling surface. Even in such a case, it is possible to manufacture a titanium clad steel plate without roughening of the titanium surface.
