Ama-valve castings ajwayele ukukhiqiza amaphutha

1. I-stomata

Lona umgodi omncane owakhiwe igesi ukuthi inqubo yokuqinisa insimbi ingaphumi ngaphakathi kwensimbi. Udonga lwayo lwangaphakathi lubushelelezi futhi luqukethe igesi, ene-reflectivity ephezulu kumagagasi e-ultrasonic, kodwa ngenxa yokuthi ngokuyisisekelo iyindilinga noma i-ellipsoid, iyiphuzu lephuzu, elithinta ubude bayo bokubukeka. Imbobo yomoya ku-ingot yenziwa isicaba ibe indawo engalungile ngemva kokufoja noma ukugingqika, okuzuzisayo ukutholwa ngokutholwa nge-ultrasonic.

2. Clip slag

I-slag enqubweni yokuncibilikisa noma i-refractory emzimbeni wesithando somlilo ixebuka ibe yinsimbi ewuketshezi, futhi ibandakanyeka ekubunjweni noma engosini yensimbi lapho ithululwa, yenza isici se-clamp ye-slag. I-slag ngokuvamile ayitholakali yodwa, ngokuvamile isesimweni esiminyene noma ihlakazeke ekujuleni okuhlukene, ifana nokukhubazeka kwevolumu kodwa ngokuvamile inomugqa othize.

3. Ukukhipha imifantu

Ukuqhekeka kokusakazwa kubangelwa ikakhulukazi ukucindezeleka kokuncipha kokuqiniswa kokupholisa kwensimbi kudlula amandla okugcina ezinto ezibonakalayo, kuhlobene nokuma komklamo wokuphonsa kanye nenqubo yokuphonsa, futhi kuhlobene nokuzwela kokuqhekeka kokunye ukungcola ezintweni zensimbi (njengokuqukethwe okuphezulu kwesibabule, ukuqina okubandayo, okuqukethwe okuphezulu kwe-phosphorus, njll.). Ku-spindle, kuzophinde kube nemifantu ku-crystal shaft, futhi ku-billet forging elandelayo, kuzohlala ku-forging njengoqhekeko lwangaphakathi lokuqamba.

4. Phendula isikhumba

Lokhu kuyinto steelmaking kusukela ladle kuya ingot casting ingot, ngenxa yokuthulula ukuphazamiseka, ikhefu, batheleka phezu liquid metal emoyeni ifomu ukupholisa ngokushesha oxide ifilimu, ukuthululela entsha ensimbi uketshezi izogqekeza emzimbeni ingot bese kwakha amaphutha hierarchical (indawo), it in the okwalandela ingot billet forging akuyona forging.

5. I-Anisotropy

Lapho i-casting noma i-ingot ipholile futhi iqinisiwe, isivinini sokupholisa esivela phezulu kuya enkabeni sihlukile, ngakho-ke izicubu ze-crystallization ezihlukene zizokwakhiwa, okubonisa i-anisotropy yezakhiwo zemishini, futhi kuholela ku-anisotropy yezakhiwo ze-acoustic, okungukuthi, kukhona isivinini somsindo esihlukile kanye nokuncishiswa komsindo kusukela enkabeni kuya phezulu. Ukuba khona kwale anisotropy kungaba nomthelela omubi kusayizi kanye nendawo yeziphambeko ezihloliwe ngesikhathi sokutholwa kwe-ultrasonic.

Ngaphandle kwalokho, i-Tianjin Tanggu Water Seal Valve Co., Ltd. iyinhlangano yamabhizinisi asekela isihlalo esinwebekayo esithuthukile, imikhiqizoI-valve ye-wafer butterfly isihlalo esinwebekayo, i-lug butterfly valve, i-valve ye-butterfly eyi-flange ephindwe kabili, i-flange ephindwe kabilii-valve butterfly eccentric, i-valve yebhalansi, i-wafer dual plate check valve,I-Y-Strainernjalo njalo. E-Tianjin Tanggu Water Seal Valve Co., Ltd., siyaziqhenya ngokuhlinzeka ngemikhiqizo esezingeni eliphezulu ehlangabezana namazinga aphezulu embonini. Ngohlu lwethu olubanzi lwama-valve nokufakwa, ungasethemba ukuthi sizokunikeza isisombululo esiphelele sohlelo lwakho lwamanzi. Xhumana nathi namuhla ukuze ufunde kabanzi mayelana nemikhiqizo yethu nokuthi singakusiza kanjani.
