| Angang-Tiantie Corporation hot dip galvanizing line, the main line productiondesign by the Italian Danieli, annealing furnace designed by the French Sellars,officially put into operation at the end of2009, running well．. Currently ago throughthe unit into operation and the situation in terms of production, the unit has played ahuge role and advantages, to produce household appliances and surface quality,performance, holds a leading position in the country, in order to seize market shareAngang do Tiantie an important contribution, but also made great economic benefits．.In this paper, in order to Angang-Tiantie company galvanizing production linefor example, introduced the production of hot galvanized steel sheet technologydevelopment, domestic and foreign development situation of hot dip galvanized steelsheet, and elaborates on the hot galvanizing production line process．.Article hot dipgalvanizing line for cold rolling mill automation system from design to control arediscussed in detail, from the unit’s production process layout, equipmentcharacteristics analysis and analytical description of the production processparameters to seek automation system design and system configuration andcomposition, then discusses unit automation system control plan．.Based on the premise of familiar with the development of hot dip galvanizedsteel sheet, function of automatic control system in hot galvanizing production lineand galvanizing furnace are introduced, the annealing furnace is an important part ofthe production line, the author has carried on the design of the section. And thetemperature control system are introduced, on the basis of that great disadvantagesfluctuations in temperature, and put forward the improvement scheme. |
