Magnesium alloy cast-rolling unit

A cast-rolling apparatus, comprising:

• a DC motor;
• a reducer gearbox;
• a two-stage cycloid pinwheel reducer;
• a cross-shaft universal coupling;
• a mill frame;
• a temperature regulatable cast-rolling roller, the temperature regulatable cast-rolling roller comprising a bearing seat, a bearing, a roller shell, a cast-rolling roller core, a quick-change flange, a water inlet gland cover, a water inlet pipe, a water outlet collect box, a water outlet pipe, and a temperature regulation device;
• the cast-rolling roller core comprising a cooling system and cooling water passageways;
• a screw-up cylinder;
• a spraying device;
• a guide roller;
• and
• a universal shaft end;
• wherein:
• the temperature regulatable cast-rolling roller is mounted on the mill frame and connected to the cross-shaft universal coupling via the universal shaft end;
• the cross-shaft universal coupling is connected to the reducer gearbox, the two-stage cycloid pinwheel reducer, and the DC motor;
• the two-stage cycloid pinwheel reducer is transitionally connected to the DC motor via a jaw flexible coupling;
• the water inlet gland cover is connected to the water inlet pipe via the quick-change flange;
• the water inlet pipe is connected to the temperature regulation device;
• and
• two adjacent passageways in the roller core are disposed orthogonally.
