The invention discloses a manufacturing method of a calendered complex
titanium clad steel plate used in a pan. The method comprises the following steps: taking two low
carbon steel plates which have a carbon content lower than 0.15% and are 8-12mm thick and two
titanium plates which are 2-3mm thick;
polishing one surface of the
steel plates and the
titanium plates, and superposing the
steel plates and the titanium plates by arranging the polished surfaces face to face in a four-layer order of steel-titanium-titanium-steel; sealing
peripheral gaps between each two plates by fusing while pressfitting; heating clad billet plates to the temperature of 850-920 DEG C;
calendering and cladding by a hot roll to cause a deformation rate not smaller than 65%, and then
diffusion annealing at the temperature of 750 DEG C to remove
oxide layers on the surfaces; cold rolling and
calendering at the deformation rate not greater than 10%, and then relieving stress at the temperature of 650 DEG C; separating the four-layer superposed plates to obtain two calendered complex titanium clad
steel plates used in the pan. The method helps manufacture the titanium clad steel plate by heating and calendaring the low
carbon steel and the titanium which are produced at high temperature and have low
brittleness; atoms on a titanium-steel interface are diffused with each other at the eutectic temperature to realize metallurgical bonding; the steel plates of the titanium clad steel plate are closely clad by the titanium plates of the titanium clad steel plate; the
bonding strength of the titanium and the steel is high, thus the titanium clad steel plate is an ideal complex plate for the pan.
