Nodular cam khwb cia hlau tau tawm rau 52 xyoo, nws txoj kev loj hlob sai yog qhov xav tsis thoob, txawm tias nyob rau hauv kev lag luam poob qis, cov hlau nodular tseem muaj qee qhov kev txhim kho, qee cov neeg hais tias nodular cam khwb cia hlau yog qhov tsis tsim nyog tawm ntawm tus yeej, taw qhia tias nodular cam khwb cia hlau vim. nws lub zog siab, siab tawv thiab tus nqi qis, yog li ntawd, nws tseem nyob hauv txoj haujlwm tseem ceeb hauv cov khoom lag luam, txawm hais tias tag nrho cov hlau thiab hlau casting tau poob qis hauv ob peb xyoos dhau los, tab sis cov khoom siv hlau tsis tau poob qis, thiab qhov tshwm sim ntawm cov hlau nplaum tau txhim kho txoj haujlwm sib tw ntawm cov hlau nplaum.
Nodulator yog ib qho tseem ceeb ntawm kev tau txais cov hlau nodular tam sim no. Thaum lub ntiaj teb tsis tshua muaj cog ntawm Zhbao Steel koom ua ke ua tiav lub teb chaws kev tshawb fawb project "tsis tshua muaj lub ntiaj teb peb-tus neeg sawv cev serialization", pawg tshawb fawb ntawm peb lub tsev kawm ntawv tau tshawb xyuas ntau tshaj 100 nodule tus neeg sawv cev tsim cov nroj tsuag hauv ntiaj teb thiab loj alloy ntau lawm hauv Suav teb, thiab tau txais cov khoom lag luam. cov qauv ntawm ntau tshaj 50 alloy ntau lawm nroj tsuag nyob rau hauv ntau tshaj li ib lub teb chaws xws li teb chaws Aas Kiv, lub tebchaws United States thiab Fabkis, lub teb chaws Yelemees, Nyiv, lub qub Soviet Union, Is Nrias teb thiab lwm yam loj domestic nodule tus neeg sawv cev ntau lawm cov nroj tsuag. Nws muab lub hauv paus rau kev sib piv cov khoom ntawm nodulator hauv tsev thiab txawv teb chaws thiab txhim kho kev tsim cov nodulator yav tom ntej.
