It is developed specially for steam maintenance concrete and pump water - tight concrete , with its technical characteristics up to the national concrete additive quality standard 本產(chǎn)品通過直接化學(xué)反應(yīng)及由反應(yīng)產(chǎn)生的機(jī)械推動(dòng)力松動(dòng)和破壞堵塞物,如每月定期使用可預(yù)防管道堵塞和清除自臭味。
The control system of mould level is crucial to improve the slab quality in the continuous casting process , pid controller is used in the traditional mould level control , and it has some defaults , such as : at the start - up or finishing period of casting or during the changeover of tundish , pid control has a bad effect , its overshoot is large and its transient time is long ; the erosion of the tundish stopper and the submersed nozzles lead to the accuracy of control become bad ; the abrupt falloff of block in the submersed nozzles makes the level acutely fluctuate , and pid control can not overcome the disturbances resulted from the change of casting speed 結(jié)晶器液位控制系統(tǒng)是提高連鑄產(chǎn)品質(zhì)量的關(guān)鍵環(huán)節(jié),傳統(tǒng)的連鑄機(jī)液位控制方法采用常規(guī)的pid控制,存在如下不足:開始、結(jié)束澆注和換中間罐澆注時(shí),控制效果差,超調(diào)量大,過渡時(shí)間長;塞棒頭和浸入式水口被腐蝕后引起控制精度差;浸入式水口堵塞物的突然脫落所引起的液位劇烈波動(dòng);無法克服拉速波動(dòng)引起的擾動(dòng)。
