Girazi rinoyangarara rinotumidzwa zita rekuti girazi rakanyungudutswa rinoyangarara pamusoro pesimbi yakanyungudutswa kuti rive nechimiro chakakwenenzverwa. Girazi rakanyungudutswa rinoyangarara pamusoro pesimbi yakanyungudutswa mubhavhu retini rakazadzwa negasi rinodzivirira (N).2+ H2) kubva mudura rakanyungudutswa. Pamusoro, girazi rakatsetseka (girazi rakaita seplate silicate) rinoumbwa nekupfapfaidza nekupukuta kuti pave neukobvu hwakafanana, nzvimbo yegirazi rakatsetseka uye rakapukutwa.
Maitiro ekugadzira girazi rinoyangarara
Zvinhu zvakagadzirwa kubva muzvinhu zvakasiyana-siyana zvakagadzirwa zvinoenderana nefomura yacho zvinonyungudutswa, zvinonatswa uye zvinotonhodzwa kusvika mugirazi rakanyungudutswa reinenge 1150-1100°C, uye tini rinodururwa nguva dzose mugirazi rakanyungudutswa kuburikidza nemugero wekuyerera wakabatana nebhati retini uye muchina wekuwachisa zvakadzika mubhati retini. Mutangi uye richiyangarara pamusoro pemvura yakakora yetini, pasi pekushanda kwaro kwesimba regiravhiti, kumanikidzwa kwepamusoro, simba rekudhonza remupendero wepuller uye tafura yekuchinja, mvura yegirazi inopararira, yakatsetseka, uye inotetepa pamusoro pemvura yetini (Inoumbwa kuita ribhoni yegirazi ine nzvimbo dzakati sandara dzepamusoro nedzepasi. Inodhonzwa netafura yekuchinja iri pamuswe wetangi retini uye roller yepit driving yakabatana nayo, uye inotungamirwa kutafura ye overflow roller, inoendeswa mugomba re annealing, uye yozonyungudutswa. Mushure mekucheka, chigadzirwa chegirazi rinoyangarara chinowanikwa.
Zvakanakira nezvayakaipira zvekushandisa nzira yegirazi rinoyangarara
Zvichienzaniswa nedzimwe nzira dzekugadzira, zvakanakira nzira yekuyangarara ndeizvi:
1. Hunhu hwechigadzirwa hwakanaka, senge kuti pamusoro pacho pakaita sandara, pakaenzana, uye panokwanisa kutumirwa zvinhu zvakawanda.
2. Kubuda kwacho kwakakwira. Zvinonyanya kuenderana nehuwandu hwekunyunguduka kwegirazi rinonyunguduka uye kumhanya kwekukweva kweribhoni regirazi, uye zviri nyore kuwedzera upamhi hweplate.
3. Ine mhando dzakasiyana-siyana. Maitiro acho anogona kugadzira ukobvu kubva pa0.55 kusvika 25mm pazvinangwa zvakasiyana-siyana: panguva imwe chete, mavara akasiyana-siyana uye epainternet coating anogonawo kugadzirwa ne float process.
4. Zviri nyore kushandisa nesainzi uye kuita kuti michina ishande zvakanaka, otomatiki, uye kugona kushanda nesimba.
5. Nguva refu yekushanda inobudirira inobatsira kugadzirwa kwakasimba
Dambudziko guru rekuita kwefloat nderekuti mari inoshandiswa uye nzvimbo yepasi yakakura. Kukora kumwe chete kwechigadzirwa kunogona kugadzirwa panguva imwe chete. Tsaona inogona kukonzera kuti mutsetse wese umire kugadzirwa, nekuti hurongwa hwakasimba hwesainzi hunofanirwa kudiwa kuti kuve nechokwadi chekuti mutsetse wese wevashandi nemidziyo, Zvishandiso nezvinhu zviri mumamiriro akanaka.
Saida Girazikirasi yekutenga Girazi remagetsi rinoyangarara kubva kumumiriri akavimbika kuti rigutse kudiwa kukuru kwevatengi vedu kwegirazi rakadzikama,girazi rekuvharayekubata sikirini,girazi rinodzivirirakuti zvionekwe munzvimbo dzakasiyana-siyana.
