在連鑄生產(chǎn)過(guò)程發(fā)生的各類事故中,損害最嚴(yán)重的便是漏鋼事故。 - Molten steel level in mould of continuous cast process and casting speed can directly effect temperature of molten steel in mould
摘要結(jié)晶器液位和鑄坯拉速可直接影響結(jié)晶器內(nèi)鋼液溫度。 - According to the analysis of dynamic scheduling for steelmaking - continuous casting process , a dynamic scheduling model based on just - in - time principle is formulated
摘要通過(guò)對(duì)煉鋼連鑄生產(chǎn)動(dòng)態(tài)調(diào)度問(wèn)題的分析,建立了基于準(zhǔn)時(shí)制思想的煉鋼連鑄生產(chǎn)動(dòng)態(tài)調(diào)度模型。 - When the data of logistics in current process are used for input of simulating logistics in future 100 % continuous casting process , supply of hot metal from iron - making process may not satisfy the needs of 100 % continuous casting on raw materials . because planning scheme in continuous casting process depends greatly on smelting scheme in convertor vessel , it is important for operator to balance raw materials supply , smelting and casting in order to realize the scheme of 100 % continuous casting . when some equipment are work abnormally , mixer of hot metal and lf furnace can be used for logistics buffer
用攀鋼煉鋼生產(chǎn)數(shù)據(jù)對(duì)仿真軟件系統(tǒng)進(jìn)行的測(cè)試和仿真研究結(jié)果表明:仿真系統(tǒng)的隨機(jī)數(shù)發(fā)生算法可以實(shí)現(xiàn)對(duì)作業(yè)時(shí)間的依分布隨機(jī)抽取;在相似的輸入條件下,仿真結(jié)果與實(shí)際生產(chǎn)物流的時(shí)間分布規(guī)律基本吻合,達(dá)到了仿真軟件設(shè)計(jì)的預(yù)期目標(biāo);若以攀鋼提釩煉鋼廠現(xiàn)工藝的鐵水輸入作為全連鑄后的輸入條件,則現(xiàn)工藝的物料供應(yīng)能力可能難以滿足全連鑄生產(chǎn)的要求;連鑄機(jī)的連澆計(jì)劃對(duì)轉(zhuǎn)爐爐次計(jì)劃的編制有很高的要求,合理安排來(lái)料、煉鋼與澆鑄三者間的物流平衡關(guān)系將是保證全連鑄作業(yè)的重要條件;當(dāng)出現(xiàn)設(shè)備異常情況時(shí),可以利用混鐵爐與lf爐站前等待作為物流緩沖池,通過(guò)延長(zhǎng)系統(tǒng)的平均物流時(shí)間來(lái)緩解因設(shè)備檢修和故障等擾動(dòng)所造成的影響,確保生產(chǎn)的順利進(jìn)行。 - It's difficult to find continuous casting process in a sentence. 用continuous casting process造句挺難的
- 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(kāi)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(guò)渡時(shí)間長(zhǎng);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(wú)法克服拉速波動(dòng)引起的擾動(dòng)。
