Embodiment Construction

[0109] In the following, a steelmaking and continuous casting production line is taken as an example to illustrate that under normal and abnormal conditions, the present invention can dynamically schedule and direct production on-line according to the actual conditions of the production site. The production line includes: 3 converters, 3 refining positions, 2 LF furnaces, 1 VD furnace, 4 continuous casting

[0110] Normal situation: Assuming that the 2# converter, 2# and 4# continuous casting machines are in a scheduled repair state at 10:20 at the current time, and the 4# continuous casting machine will end the maintenance at 11:00. A furnace of molten steel with the heat number 109 is cast in the 1# continuous casting machine, and the system automatically triggers the scheduling of the operation plan.

[0111] 1. Set the pouring time of the continuous casting machine. First, it is judged that the current casting of No. 1 continuous casting machine has been arranged to the last f...

Abstract

An on-line dynamic dispatching method for continuous production of steel making includes applying distributed computer system; working out a dynamic operation plan suitable for current production state by collecting data from site process and equipment, combining the set of dispatcher and using roll search mode; following the plan to carry out operation by operation station and feeding back regulation request to dispatching room for used as basis of next dispatch.

Description

Technical field [0001] The invention belongs to the technical field of steelmaking and continuous casting production planning and scheduling, and in particular provides an online dynamic scheduling method for steelmaking and continuous casting production, which realizes fast and flexible online scheduling. Background technique [0002] Steelmaking and continuous casting is an important part of steel production. After pretreatment, the molten iron in the blast furnace is transported to the steelmaking continuous casting site by torpedo trucks, and then mixed with scrap steel into the converter for smelting. The molten molten steel is subjected to argon blowing, stirring, alloying, vacuum degassing, etc. outside the furnace as required. Later, they are sent to a continuous casting machine to be cast into billets of different steel grades and specifications to provide raw materials for steel rolling production. [0003] Steelmaking and continuous casting production is different from...
