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
結晶器液位控制系統是提高連鑄產品質量的關鍵環節，傳統的連鑄機液位控制方法採用常規的pid控制，存在如下不足：開始、結束澆注和換中間罐澆注時，控制效果差，超調量大，過渡時間長；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；無法克服拉速波動引起的擾動。The research showed that basin is the more important feeding resource than runner in runner type gating system in lost wax casting. therefore, on the basis of the basin as feeding resource, runner and ingate as feeding channel, a new design method for runner type pouring and feeding system in investment casting was developed. the corresponding feeding mathematical pattern and allowable total weight listed for casting cluster with different basin were established after analyzing the practical feeding of basin and the calculating process for design was described in detail
在熔模鑄造橫澆道型澆注系統中，澆口杯是比橫澆道更為重要的補縮源，因此在立足於澆口杯為補縮源、橫澆道和內澆道為澆注補縮通道的基礎上，開發了適用於熔模鑄造橫澆道型澆注補縮系統設計的新設計方法，在詳細分析了澆口杯的實際補縮情況后，建立了相應的數學補縮模式和不同澆口杯的鑄件組許用鑄件總質量表，並具體介紹了設計計算過程。The company developed special magnesium melting furnace, protective gas, quantitative transport equipments, and vacuum casting equipments which can satisfy the production of various kinds ofmagne sium alloys
研製出的鎂合金專用熔煉爐氣體保護裝置定量澆注設備和真空吸鑄設備等可滿足不同種類的鎂合金產品的生產。Abstract : using furan sand to produce heavy diesel engine block and crankshaft eliminated defects of castings including “ penetration / burn - in ”, “ shrinkage porosity ”, “ big dimension deviation ” of cylinder block, “ penetration / bum - in ”, “ misrun ” and “ run - out ” of crankshaft, and so on
