pressure charging system

350 m3 blast furnace is analyzed systemically by using six sigma management tools. The essential reasons of influencing pig iron silica content are found out. They are coal ratio, material charge, furnace top pressure, coke ash and charging system.

利用六西格玛管理提供的工具，对铸管公司1350m3高炉的生铁含硅量进行了系统分析，找出了影响生铁含硅量的根本原因是煤比、料批、炉顶压力、焦炭灰分及料制。

The pressure charging regulation ( PCR) system of high-pressure common-rail diesel engine was used as object for control strategy, advanced variable geometry turbocharger ( VGT) was selected as actuator of system development.

提出了高压共轨柴油机增压调节（PCR）系统控制策略的开发，采用先进的可变截面涡轮增压器作为系统开发的执行器。
