Problems solved by technology

[0002] In the traditional molten steel pouring process, after the molten steel operation is completed at the tapping station, the ladle and molten steel are hoisted to a suitable position by driving, and then transported to the pouring station by a low-rail transfer ladle car, and then lifted and poured by a metallurgical crane. The process is complicated and cumbersome, taking up more manpower and material resources, which is not conducive to safe production

Abstract

The embodiment of the invention discloses a molten steel pouring control method and a pouring truck. The molten steel pouring control method comprises the following steps: comparing an average pouringspeed in an actual timing period with an ideal average pouring speed to obtain a positive and negative deviation of speed; comparing the absolute deviation of the actual speed with the absolute deviation of the ideal speed to obtain a positive and negative deviation of speed deviation; acquiring a mass value as a an end mass value when the actual timing period is finished to obtain an mass valueas an initial mass value when the actual timing period is started; adjusting opening and closing of a steel ladle port in real time according to the speed deviation to control the actual flow rate ofmolten steel; adjusting opening and closing of the steel ladle port according to deviation of the speed deviation to control the real time molten steel pouring speed; and controlling the total pouringweight of molten steel according to a difference value between the end mass value and the initial mass value.

Description

technical field [0001] The invention relates to the field of metallurgy, in particular to a molten steel pouring control method and a pouring car. Background technique [0002] In the traditional molten steel pouring process, after the molten steel operation is completed at the tapping station, the ladle and molten steel are hoisted to a suitable position by driving, and then transported to the pouring station by a low-rail transfer ladle car, and then poured by a metallurgical crane. The process is complex and cumbersome, taking up more manpower and material resources, which is unfavorable for safe production. In the new steel pouring process, in order to ensure the good quality of pouring products, there are more and more strict requirements on pouring weight, time and safety. Based on this process requirement, a molten steel pouring car is developed. The whole pouring process can be realized automatically, and it can be inspected and operated remotely. Contents of the ...
