Claim 0:
1. A continuous rolling device with interfacial temperature-force controllability for a seamless metal cladding pipe, comprising a multi-roller skew rolling mill set (1), an interfacial temperature-force controlled rolling mill set (2) and a sizing and finishing mill set (3) which are sequentially distributed along a rolling axis; wherein,
the interfacial temperature-force controlled rolling mill set (2) comprises an interface temperature control module (201) and an interface pressure control module (202) which are sequentially distributed along the rolling axis, the interface pressure control module (202) comprises two racks (2021) and a plurality of controlled rolling rollers (2023) circumferentially and evenly distributed along the rolling axis, two ends of each of the controlled rolling rollers (2023) are respectively mounted on the two racks (2021) through corresponding screwdown apparatuses (2022), and the interface pressure control module (202) realizes passive driving through a spiral pushing force of a skew roll bonding process of the multi-roller skew rolling mill set (1) to a primary roll bonding blank and a traction force of the sizing and finishing mill set (3) to an intermediate roll bonding blank; and
the controlled rolling roller (2023) is divided into a controlled pressure bonding section (20231), a finishing and rounding section (20232) and an unloading and expanding section (20233), a length L1 of the controlled pressure bonding section (20231) is 40% to 80% of a length L of the controlled rolling roller (2023), and a cone angle α1 of the controlled pressure bonding section is 0° to 10°; a length L2 of the finishing and rounding section (20232) is 20% to 40% of the length L of the controlled rolling roller (2023), and a cone angle α2 of the finishing and rounding section is 0° to 2°; and a length L3 of the unloading and expanding section (20233) is 10% to 30% of the length L of the controlled rolling roller (2023), and a cone angle as of the unloading and expanding section is 0° to 15°.
