The Development And Application Of Sublance In Converter Dephosphorization Of 300 Tons

In recent years,the steel market continues to weaken.The production situation of iron and steel industry is more and more serious.Iron and steel enterprises on the one hand,face the rising cost of raw materials and overall excess capacity brings the great pressure.On the other hand,also face steel market atrophy with the strengthening of the competition between the industry.Beijing Shougang company faced severe situation,in order to be able to send to the promotion of the competitiveness of the enterprisein such a market,Jingtang steelmaking actively makes changes.First,Sublance system represented by the automatic stellmaking technology is an advanced control technology of converter smelting.Jingtang company based shougang Beijing 300 tons of dephosphorization converter status quo as the research object.On the basis of the selection of sublance mechanical equipment,through the combination with advanced control technology at home and abroad.The overall control function of sublance system is designed.The control function mainly includes three operation cycle : Reset cycle,Connecting cycle,Measuring cycle.After the design of each cycle developed and applied.Finally,the continuous operation of three cycles,and the overall control of the sublance system.After the program control is satisfied,the visual of the control operation screen should be realized,and the remote operation of the production operator.There is no obvious hidden danger and failure after the project has been put into use,combining with advanced control technology,has reallzed the jing tang company 300 tons of dephosphorization of bof steelmaking continuous temperature measurement,sampling for the subsequent automation steelmaking,do a good job,since the dephosphorization sublance after use,even more than the expected goal,to achieve the objective of economic benefits.
