Description

A kind of steel smelting-continuous casting production run inline graphics man-machine interaction dispatching method

Technical field

The present invention relates to steel smelting-continuous casting technical field, specifically a kind of steel smelting-continuous casting production run inline graphics man-machine interaction dispatching method.

Background technology

Steel smelting-continuous casting production run is the core link in the production procedure of modern steel enterprise, and its production run is that the processing of the liquid three large operations such as high temperature liquid iron process converter smelting, refining furnace refining and conticaster casting is formed to final solid-state slab.First, the high temperature liquid iron of blast furnace output,, and is poured into converter and blows to iron-smelter by torpedo car carrying molten iron.The process of blowing is the process that molten iron transforms to molten steel, is the molten iron under hot conditions is further smelted for the lower molten steel of carbon content, reaches certain temperature and start tapping after converter smelting.Secondly, the molten steel of converter output is poured ladle into, by overhead traveling crane and chassis, the ladle that molten steel is housed is transported to corresponding refining equipment.Refining process will be adjusted high-temperature molten steel composition, temperature, carries out the processing such as dark decarburization, desulfuration and removal impurity, makes common molten steel become high-quality molten steel, to guarantee that the conticaster slab of casting out meets temperature and the composition requirement of specific steel grade.Finally, liquid steel refining processing finishes, by chassis and driving by steel ladle handling to the conticaster of appointment before, by the lower mouth of a river injection tundish of ladle, the molten steel of tundish constantly enters crystallizer, by crystallization, is vibrated after cooling and just from conticaster, is pulled out slab.

Since 2000, China's steel smelting-continuous casting technology makes decided progress, its production run is the core link in the production procedure of modern steel enterprise, and in the whole production run of steel smelting-continuous casting, liquid steel temperature, molten steel composition and process time are the key parameters of system operation.The requirement that market is more and more higher to steel product quality, has caused more and more narrow composition range, and continuous casting is the slab quality that guaranteed and stable technological process, again liquid steel temperature has been proposed to more harsh requirement.Under the promotion of high-efficient continuous casting technology, steel smelting-continuous casting system operational process serialization degree increases day by day, and rhythm of production is also had higher requirement.Effective control of liquid steel temperature, molten steel composition and process time, will play vital effect to the operation optimization of whole steel smelting-continuous casting production system.
