The invention discloses a feeding control method and system of converter auxiliary raw materials and is applied to the automatic control field. The control method includes the steps that unloading trolleys on belt conveyors are controlled to be positioned, and the belt conveyors are controlled to be started one by one; after all the belt conveyors are in a running state, the belt conveyors sequentially acquire the auxiliary raw materials from a material supplying bin based on the pre-feeding marshalling, and convey the auxiliary raw materials to corresponding material needing bins for feeding; in the process that the auxiliary raw materials are conveyed to the corresponding material needing bins, whether material interruption happens to the material needing bins or not is monitored; and when it is monitored that material interruption happens to one of the material needing bins, after the feeding sequence of the material needing bin where material interruption happens is preferentially inserted into the pre-feeding marshalling, the auxiliary raw materials continue to be acquired from the material supplying bin to be conveyed to the corresponding material needing bins to be fed. In this way, the technical problem that existing converter smelting feeding is poor in control accuracy is solved, and therefore the feeding reliability is greatly improved.
Description
technical field [0001] The invention relates to the field of converter smelting, in particular to a control method and control system for feeding auxiliary raw materials to a converter. Background technique [0002] With the current increasingly fierce competition in the steel industry, small steel mills are gradually being phased out, and large-scale converter smelting is a major advantage. However, due to its huge volume, the required raw materials also increase accordingly. Only a strong and stable feeding system can continue to maintain the advantages of steelmaking. A superior feeding system is the lifeline of steelmaking and smelting. This superiority is reflected in whether it has high-tech feeding technology. [0003] However, the existing feeding system is based on the manual screen to carry out the manual operation of moving the car, turning over the flap, and starting the vibrating feeder. However, the accuracy of the feeding control is poor due to manual interf...
