(57) [Abstract] [Purpose] To provide a titanium clad steel sheet having high joint strength and a low-cost manufacturing method thereof. [Structure] (1) In the method for producing a titanium clad steel sheet by hot rolling, the assembled slab for rolling is subjected to rolling for 1 pass or more at a rolling reduction of 15% or more at 950 to 1100 ° C in the first hot rolling step, and then the 900 ℃ -600 in 2 hot rolling process A method for producing a titanium clad steel sheet, which comprises rolling at a rolling reduction of 5% or more at 0 ° C for one or more passes. In the above, after the first hot rolling step, 9 You may cool to 00 degrees C or less, and then apply a 2nd hot rolling process. (2) A titanium clad steel plate manufactured by the above method. [Effect] It is possible to achieve mass production of titanium clad steel sheet using conventional hot rolling equipment for steel. The titanium clad steel sheet of the present invention has a high reduction ratio and a high bonding strength because the rolling reduction is large and the yield and the bonding strength are improved. |
