Research of Weight Control and Lightening Practice for Civil Aircraft

Weight control runs through the entire life cycle of civil aircraft from design, manufacturing to operation. Though the pacing factor of aircraft's weight majorly stays in the link of design, in the view of the experience of domestic and foreign manufacturers, it still has optimization in the stage of aircraft mass production. This article generalizes […]

OPERATION PRACTICE TO LOWER CHARGE LEVEL IN MEDIUM MAINTENANCE OF 3200 m~3 BLAST FURNACE

It is concluded the measures in operation practice of lowering charge level in 3 200 m3 blast furnace4# of Tang Steel: adopting empty charge line to recover gas,determining charge level with multi ways,atomization pouring water,strictly controlling top temperature within 250 to 300,reasonably arranging slag tapping and blast furnace tapping.
