Zvinoenderana nemaitiro eindasitiri mune inorema muchina chikamu, yemahara forging inogadzirwa uchishandisa ma hydraulic presses ine forging inodarika 1000 matani inogona kunzi yakakura forging. Zvichienderana nehunyanzvi hwekugadzira ma hydraulic press forging for free forging, izvi zvinongoenderana neshaft forgings inorema kupfuura matani mashanu uye disc forgings inorema pamusoro pematani maviri.
Hunhu uye hwakakosha hunhu hwemafogi makuru ndiwo hukuru hwavo uye huremu hunorema. Semuenzaniso, saizi ye600MW steam turbine generator rotor forging ndeye φ1280mm×16310mm, inorema 111.5 matani. Saizi ye2200-2400MW turbine jenareta jenareta rekugadzira ndeye φ1808mm×16880mm, inorema 247 matani.
Nekuda kwehukuru hwavo hukuru uye huremu, mafogi makuru anofanirwa kuve akagadzirwa zvakananga kubva kune hombe simbi ingots. Zvinonyatsozivikanwa kuti ingots huru dzesimbi dzinowanzova nenyaya dzakakomba dzakadai sekuparadzanisa, porosity, shrinkage, non-metallic inclusions, uye marudzi akasiyana-siyana ezvimiro zvisina kufanana. Ivo zvakare vanowanzove vane yakakwira gasi yemukati, uye izvi zvirema zvinonetsa kubvisa panguva dzinotevera dzekugadzira. Nekuda kweizvozvo, yakakosha kemikari kuumbwa kusiri-kufanana, kwakasiyana zvimiro zvakakanganisika, uye mazinga akakwira ezvinokuvadza gasi zvemukati zvinowanzovepo mukugadzira kukuru. Izvi zvinoita kuti maitiro ekupisa ekurapa mafogi akaomesesa, anotora nguva, uye anodhura. Nokudaro, kunyatsoteerera kunofanira kubhadharwa panguva yekurapa kwekupisa.
Uyezve, nekuda kwehukuru hwavo uye huremu, mafogi akakura ane huwandu hwakanyanya hwekupisa, izvo zvinoita kuti zvisakwanise kuwana yakakwira yekudziya uye kutonhora mazinga panguva yekupisa nhanho dzekurapa. Naizvozvo, kune mafogi makuru anoda shanduko huru muchimiro chemukati kuburikidza nekudzikamisa kana kudzima kuti asangane nepamusoro-kuita uye mhando zvinodiwa, yakagadzikana zvakanyanya supercooled austenite uye yakakwirira kuomarara simbi inofanira kushandiswa. Mienzaniso inosanganisira Ni-Cr-Mo, Ni-Mo-V, uye Ni-Cr-Mo-V akatevedzana masimbi. Nekudaro, masimbi ane kugadzikana kwakanyanya kwe supercooled austenite anotarirwa kunhaka yezvimiro, zvichikonzera kukora uye kusaenzana saizi yezviyo mune alloy simbi forgings. Kugadzirisa nyaya iyi, maitiro anokosha uye akaoma ekupisa kupisa anowanzodiwa.
Kana iwe uchida rumwe ruzivo nezve WELONG forgings yemhepo turbine uye jenareta, ndapota sununguka kubata
