(1) High yield efficiency: Nws yuav siv 154 xuab moos los tsim ib lub tog raj kheej nrog ib lub puab diam 420 hli thiab ntev ntawm 12 metres siv cov qauv qub, thiab nws yuav siv sij hawm tsuas yog 4 feeb los tsim nrog txoj kev txias duab.
(2) Muaj tus nqi zoo tshaj: Txij thaum lub taub hau ntawm qhov tho qhov tho txawv kuj yog ib qho kev qhia, thaum lub sij hawm ua qhov kev txiav, lub ntxhib raj yuav raug rau nws tus kheej qhov hnyav, ua rau lub taub hau thiab qhov tho qhov tho tawm mus tawm , ua rau cov khoom pov tseg. Qhov qhabnias tseeb tsuas yog siv tau li ntawm 60%, thiab nws tuaj yeem tsim los ntawm cov qauv kev kos duab. Cov qhabnias muaj peev xwm ncav tau tshaj 95%.
(3) Kev siv cov hlau loj: Cov khoom siv lub cev kheej yog tsim los ntawm txoj kev tho txawv, thiab kev siv hlau yog tsuas yog 50-70%. Thaum tsim los ntawm cov qauv kev kos duab, cov hlau tsis yog muab txiav rau hauv cov hmoov hlau xwb, tiam sis tuaj yeem txuas ntxiv tau 30%, thiab cov nqi siv hlau tau nce mus txog 95%.
(4) Nws tuaj yeem txhim kho cov khoom siv hlau ntawm cov hlau tiav: Nws yog tsim los ntawm cov qauv kev kos, yog li ntawd qhov seem yog plastically deformed los ntawm ntau tshaj 30%, thiab lub zog ntawm cov hlau ntawm lub raj tiav lawm zoo heev mus rau kev ua hauj lwm hardening. Feem ntau, lub zog ntawm lub puab txheej ntawm cov raj tiav lawm yog nce ntawm 60%. High-precision txias-twist tubes yog ua los ntawm cov xim tsis muaj hlau ntxig rau hlau thiab cov hlua ncaj nraim. Tom qab tshuaj kho tshuaj, lawv kos rau ntawm cov khoom siv tshwj xeeb txias-drawing thiab tsim los ntawm cov tshwj xeeb deformation cov txhooj los tsim cov hlab-xim. Qhov dim qhov tseeb ntawm H10 ~ H8, ncaj ntawm 0.35 ~ 0.5 hli / m, deg roughness Ra1.6-0.4
