Molten metal pouring device and molten metal pouring method

A pouring method for using a pouring apparatus for pouring by tilting a ladle such that a molten metal pouring position in which the molten metal is poured into a mold from a nozzle of the ladle is maintained at a predetermined position, the pouring apparatus comprising:

• i) the ladle configured to include a body and the nozzle;
• ii) a controller configured to control a tilt angle of the ladle;
• iii) a surface area information storage unit storing a surface area of the molten metal that is calculated in accordance with the tilt angle of the ladle;
• and iv) a state storage unit storing various states, wherein the body includes a side face portion, an inner surface of the side face portion is formed in a cylindrical shape or in a conical shape, wherein the nozzle includes a nozzle tip provided at one end thereof and is integrated with the body on a side of the body, in order to guide the molten metal in the body to the nozzle tip and to pour out the molten metal through the nozzle tip, and wherein the molten metal pouring, performs the method, via the controller, comprising:
• reading out a present tilt angle of the ladle stored in the state storage unit;
• reading out a surface area inverse ratio, from the surface area information storage unit, that corresponds to the read out present tilt angle;
• calculating a tilt angular speed required for the ladle on the basis of the read out surface area inverse ratio and a predetermined preset angular speed;
• and
• controlling the tilt angle of the ladle such that a tilt angular speed is the calculated tilt angular speed.
