Waya yesimbi yakasungirirwa yagara iripo kwenguva refu, uye kugadzirwa kwayo nemaindasitiri kunogona kuteverwa kumashure kusvika kuma1920. Yakagadzirwa zvakanyanya mumakore apfuura, zvichikonzera mhando dzakasiyana dzezvigadzirwa zvine hunhu hwakasiyana hwakakodzera kushandiswa kwakasiyana-siyana. Izvi zvinosanganisira waya yakadhonzwa inotonhora, waya yakatwasuka uye yakapfava, waya isina kugadzikana, waya yakabatidzwa uye waya yakakoshwa. Zvigadzirwa izvi netambo dzesimbi dzakasungirirwa dzakagadzirwa kubva mazviri zvave mhando dzesimbi dzakasungirirwa dzinonyanya kushandiswa pasi rose.

Waya yesimbi yakasungirirwa yakagadzirwa nesimbi ine kabhoni yepamusoro 12.7mm yakagadzirwa nesimbi ine kabhoni yepamusoro yakagadzirirwa kuzadzisa zvinodiwa zvekusimbisa kongiri yakasungirirwa yakagadzirwa nesimbi. Yakagadzirwa netambo yakasungirirwa yakagadzirwa nesimbi ine kabhoni yakawanda, inorapwa nekupisa uye inotonhorera kuti iwane hunhu hunodiwa. Kabhoni iri mumhando iyi yewaya yesimbi iri pakati pe0.65% kusvika 0.85%, uye sarufa nephosphorus zviri mukati mayo zvakaderera, zviri pasi pe0.035%.
Simba rekudhonza rewaya yesimbi rinowanzova pamusoro pe1470MPa, uye simba rayo rakachinja zvishoma nezvishoma kubva pa1470MPa ne1570MPa kusvika pa1670~1860MPa. Panyaya yedhayamita, waya yesimbi yakawedzera kubva pa3mm kusvika pa5 kusvika 7mm pari zvino.
Kubva pamaonero erudzi, waya yesimbi yakasungirirwa ye12.7mm ndeye waya yesimbi yekongiri yakasungirirwa yemhando yepamusoro. Yakagadzirirwa zvakananga kusangana nezvinodiwa zvekusimbisa kongiri yakasungirirwa, zvichipa simba rekuvaka uye kugadzikana kumapurojekiti ekuvaka achishandisa iyo.
Tichitarisa zvirevo, waya yesimbi ine 12.7mm ine kabhoni iri pakati pe0.65% kusvika 0.85%, zvichiita kuti ishande zvakanaka kuti igare kwenguva refu. Ine sarufa nephosphorus zvishoma, zvichiwedzera kushanda kwayo. Simba rekudhonza waya iri kupfuura 1470MPa, uye dhayamita iri pakati pe5 kusvika 7mm.
Waya yesimbi yakasungirirwa yakagadzirwa nesimbi ye12.7mm inoshandiswa zvakanyanya mumapurojekiti akasiyana-siyana ekuvaka nekuda kwesimba rayo guru rekudhonza uye kushanda kwayo kwakanaka. Inonyanya kushandiswa muzvivakwa zvekongiri yakasungirirwa yakagadzirwa kuti ipe simba uye kugadzikana. Ingave ichishandiswa mumabhiriji, zvivakwa kana mamwe mapurojekiti ezvivakwa, waya iyi yesimbi inovimbisa kusimba uye kushanda kwenguva refu kwezvivakwa zvainotsigira. Kugona kwayo kushanda kwakasiyana-siyana uye kuvimbika kunoita kuti ive chikamu chakakosha chezvivakwa zvemazuva ano.
Muchidimbu, waya yesimbi yakasungirirwa yakagadzirwa ne12.7mm chigadzirwa chemhando yepamusoro chinosangana nezvinodiwa zvekusimbisa kongiri yakasungirirwa yakagadzirwa nesimbi. Simba rayo guru, sarufa shoma uye phosphorus, uye hunyanzvi hwakasiyana-siyana zvinoita kuti ive yakakodzera kushandiswa kwakasiyana-siyana pakuvaka. Nenhoroondo yayo refu uye kuzivikanwa kwayo pasi rose, waya iyi yesimbi yave chikamu chakakosha muindasitiri yekuvaka, ichivimbisa kugara kwenguva refu uye kugadzikana kwezvivakwa pasi rese.
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.
