Since the molten steel has a temperature of over 1000°C and is in a flowing state, any carelessness or operational error during lifting and pouring can lead to the spillage or falling of the molten steel, resulting in serious accidents involving personnel and equipment. Therefore, ensuring the safety of lifting and pouring operations is crucial for the operation of casting cranes. Metallurgical cranes and casting cranes are primarily used in smelting workshops for transporting molten steel and pouring steel ingots. Their structure is essentially the same as that of conventional bridge cranes; they have primary and secondary lifting mechanisms, with the primary and secondary trolleys moving along the primary and secondary girders respectively. In the operations of transporting molten steel and casting ingots, the main hook is used to lift the ladle, while the auxiliary hook is used for pouring the steel from the ladle. In addition to adhering to the general operating rules and relevant regulations for bridge cranes, crane operators must also master the following rules and operational principles: 1) They should be familiar with the entire process of lifting operations, understand the requirements for each step and how these steps are connected to one another, in order to ensure the smooth progress of steel liquid lifting and pouring tasks. 2) Before lifting the pouring ladle, it is necessary to confirm that the hook has properly and securely caught the neck of the lifting eye, and then lift the ladle under the instruction of a qualified personnel. 3) To prevent the hot molten steel from directly heating the hook assembly, the hooks used for lifting the ladle should be equipped with insulation devices, such as partitions or long-necked hooks. 4) The molten steel should not be filled to capacity, to prevent swaying caused by rapid starting or braking of the trolley, which could lead to the splashing of molten steel and injury to people. 5) Before lifting the molten steel each time, a trial lift should be performed first: the ladle containing the molten steel is slowly raised to a height of 200 mm above the ground, then lowered and braked to test the reliability of the lifting brake. The operation of lifting the molten steel can only be carried out officially if it does not exceed the permitted descent distance (generally not more than 100 mm). 6) When lifting molten steel, it is strictly prohibited to pass directly above a person’s head. 7) When lifting molten steel, the speed should not be too fast; it is advisable to set the controller handle on the second gear. 8) When starting the lifting mechanism to raise or lower the ladle, it is strictly prohibited to activate other mechanisms such as the main crane or the jib crane, so that the crane operator can concentrate and prevent accidents caused by accidental operations. 9) Before flipping the ladle, the hook of the auxiliary trolley should be used to securely hook the flipping ring on the ladle. At work, follow the instructions of the dedicated staff only. 10) The wire rope of the auxiliary lifting mechanism must not come into direct contact with the ladle or the balance frame. 11) When pouring molten steel into the furnace from the pouring trough, the ladle must be moved only along the edge of the trough and kept at an appropriate height. 12) When opening the \"tongue brick\" of the pouring ladle, no one is allowed to stand under the ladle while operating the pressing rod.
