Waya yesimbi yekongiri yakasungirirwa, inozivikanwawo sewaya yesimbi ine kabhoni yakawanda, imhando yekuvaka inoshandiswa zvakanyanya uye yakavimbika inosangana nezvinodiwa zvekusimbisa zvivakwa zvekongiri yakasungirirwa. Waya iyi yakagadzirwa netambo yesimbi ine kabhoni yakawanda, iyo yakagadziriswa nekupisa uye yakatonhodzwa kuti ive nechokwadi chekuti ine kabhoni yepamusoro uye inoshanda zvakanaka. Waya iyi ine kabhoni iri pakati pe0.65% kusvika 0.85%, sarufa nephosphorus zviri pasi pe0.035%, uye inogadzirwa zvinoenderana nezvinodiwa neindasitiri.
Waya yesimbi yakasungirirwa yave nemakore akawanda ichivandudzwa kubva pakugadzirwa kwayo mumaindasitiri uye kushandiswa kwayo muma1920. Nhasi, zvigadzirwa zvakasiyana-siyana zvakagadzirwa kuti zvizadzise zvinodiwa zvakasiyana-siyana zvekuvaka. Izvi zvinosanganisira waya inotonhorera, waya yakatwasuka, waya inorerukirwa zvishoma, waya yakabatidzwa uye waya yakakoshwa. Zvigadzirwa izvi zvakasiyana-siyana, kana zvichishandiswa mukugadzira tambo dzesimbi dzakasungirirwa, zvave mhando dzesimbi dzakasungirirwa dzinonyanya kushandiswa pasi rose.
Simba rekudhonza rewaya dzesimbi dzekongiri dzakasimbiswa rinowanzova pamusoro pe1470MPa, uye simba rayo rakachinja kubva pa1470MPa ne1570MPa kusvika pa1670~1860MPa. Dhayamita yewaya yakachinjawo, kubva pa3-5 mm kusvika pa5-7 mm. Kuwedzera kwesimba nedhayamita kunoita kuti zvivakwa zvekongiri zvakasimbiswa zvigadzikane uye zvivimbike.
Waya dzekongiri dzakagadziriswa dzinoshandiswa zvakanyanya muindasitiri yekuvaka. Simba rayo guru rekusimba uye kugara kwenguva refu zvinoita kuti ive yakanaka pakusimbisa zvivakwa zvakasiyana-siyana zvekongiri zvakaita semabhiriji, zvivakwa nemigwagwa mikuru. Inoderedza kushushikana kwekongiri, inoderedza kutsemuka uye inowedzera kugona kwayo kutakura mutoro. Pamusoro pezvo, kugona kwayo kutakura zvinhu zvakawanda kunoita kuti ive nyore kugadzirisa kuti ienderane nezvinodiwa zvekuvaka.
Muchidimbu, waya yekongiri yakagadzirwa kare imhando yepamusoro yekuvaka inogona kupa simba rakanaka pakuvaka kwekongiri yakagadzirwa kare. Rudzi rwayo rwezvigadzirwa uye magadzirirwo ayo zvinoita kuti zvese zvinodiwa pakuvaka zvizadzikiswe. Nesimba rayo guru, kugara kwenguva refu uye kushanduka-shanduka, yave sarudzo inofarirwa muindasitiri yekuvaka yepasi rose. Ingave ichishandiswa mumabhiriji, zvivakwa kana migwagwa mikuru, waya yekongiri yakagadzirwa kare inovimbisa kuvimbika kwechivakwa uye kugara kwenguva refu.
Kushandiswa
Sezvo makambani makuru eChina ari kutungamira muindasitiri yezvinhu zvesimbi, kutengeserana kwesimbi kwenyika yese uye logistics "zana rakanaka rebhizinesi", makambani ekutengesa simbi eChina, "Makambani epamusoro zana epachivande muShanghai". Shanghai Zhanzhi industry Group Co., Ltd., (yakapfupikiswa kuZhanzhi Group) inotora "Kuvimbika, Kushanda, Kugadzira Zvinhu Zvitsva, Kukunda-Kukunda" senzira yayo yega yekushanda, inogara ichienderera mberi nekuisa zvinodiwa nevatengi pakutanga.
