Zvidhinha zveSimbi Yekuyerera
Zvidhinha zvesimbi zvinoyererazvinoreva zvidhinha zvisina kusimba zvinoiswa mumigero yeplate yepasi peingot casting kuti zvibatanidze zvidhinha zvesimbi zvinoyerera uye ingot mold, inozivikanwa serunner brick. Inonyanya kushandiswa kuderedza kuramba kwesimbi yakanyungudutswa uye kudzivirira kubuda kwesimbi. Hunhu hukuru hunosanganisira kuramba kupisa kwakanyanya, kuramba kupera, kuyerera zvakanaka, kuiswa nyore uye kuramba moto zvakanaka.
1. Kupatsanura nezvinhu:
Ivhu: (1) Ivhu:Iyi ndiyo mhando yesimbi inoshandiswa zvakanyanya, yakagadzirwa nevhuwowo zvaro. Kunyangwe mutengo wayo wakaderera, haichatsvi zvakanyanya uye haishande kwenguva refu, uye yakakodzera kune mamwe magayo madiki esimbi kana kushandiswa kwenguva pfupi.
(2) Aruminiyamu yakakwirira:Chidhinha ichi chesimbi inoyerera chine aruminiyamu yakawanda, chinodzivirira moto zvakanyanya, uye chinogona kuramba chakasimba munzvimbo dzinopisa zvakanyanya. Chinowanzo shandiswa mumakambani makuru esimbi, kunyanya mumabasa ekugadzira simbi anoda kutsungirira tembiricha dzakakwirira kwenguva yakareba.
(3) Zvizhinji:Makristaro epamusoro akaita setsono ane chimiro chakasiyana, chinogona kudzivirira kukurwa kwevhu nesimbi yakanyungudutswa. Parizvino ndiyo inonyanya kushandiswa.
2. Kupatsanura zvichienderana nemabasa:
(1) Zvidhinha zvepakati
Inoshandiswa munzvimbo yepakati pesimbi yakanyungudutswa, ichitsigira nzira yekuyerera uye inoda yakakwirira
kuramba kusimba uye kuramba kukurwa kwevhu.
(2) Zvidhinha zveSimbi Zvinoparadzanisa
Inoshandiswa kuchinjisa simbi yakanyungudutswa kuenda kumaforoma akasiyana. Zvinozivikanwa zvinosanganisira maburi maviri, matatu, uye mana, zvichienderana nezvinodiwa pakuita.
(3) Zvidhinha zvemuswe
Dziri pamucheto wenzira yekuyerera kwesimbi, dzinotsungirira kukanganiswa nesimbi yakanyunguduka uye tembiricha yakakwira uye dzinoda kuramba kutyoka.
1. Kudzivirira kwakanyanya kupisa
Zvinokwanisa kutsungirira tembiricha yakanyanya ye1500–1700℃ yesimbi yakanyungudutswa kwenguva yakareba. Semuenzaniso, zvidhinha zvekuumba zvakagadzirwa neMullite zvine simba rekuramba kupisa rinodarika 1780℃, zvichiita kuti zvikodzere kushandiswa muzvinhu zvekuumba zvakagadzirwa netembiricha yepamusoro.
2. Kudzivirira kukurwa kwevhu zvakanyanya
Nechivakwa chakasimba uye chakakora, kuumba zvidhinha kunogona kudzivirira kukweshwa kwesimbi kwakanyungudutswa nekumhanya kukuru, zvichideredza kusakara panguva yekushanda.
3. Kudzivirira ngura kwakanyanya
Dzinogona kutsungirira kukurwa kwemakemikari kubva musimbi yakanyungudutswa uye tsvina dzakasiyana-siyana. Magadzirirwo akasiyana ezvinhu anogadziriswa zvichienderana nemamiriro chaiwo ekushanda.
4. Kudzivirira kwakanaka kwekupisa
Dzinogona kutsungirira kushanduka-shanduka kwekushisa nekukurumidza panguva yekuumbwa kwesimbi pasina kutsemuka kana kupwanyika.
5. Kusvibiswa kushoma nesimbi yakanyungudutswa
Maumbirwo esimbi iyi anoderedza kukweshwa kweganda uye kudonha kwezvidimbu, zvichiita kuti tsvina isapinde musimbi yakanyungudutswa uye zvinoita kuti zvigadzirwa zvesimbi zvekupedzisira zvive zvakachena uye zvine hunhu hwakanaka.
6. Kururama kwakanyatsojeka kwehukuru
Dzine nzira dzemukati dzakatsetseka, maumbirwo ekunze akajairwa, uye kushivirirana kwakasimba. Izvi zvinoita kuti majoini asapindana panguva yekuisa, zvinoderedza kuramba kwesimbi yakanyungudutswa, uye zvinodzivirira njodzi yekubuda kwesimbi.

Zvidhinha zvesimbi zvinoyereraZvinonyanya kushandiswa pakukanda pasi, zvichishanda senzira yekuti simbi yakanyungudutswa ibude kubva mundiro ichienda kuma ingot molds, zvichiita kuti simbi yakanyungudutswa iparadzirwe zvakanaka kune imwe neimwe ingot mold.
Basa Guru
Zvidhinha zvesimbi zvinoyerera, zvichipinda nepakati pazvo zvisina chinhu, zvinoita kuti simbi yakanyungudutswa ifambe nenzira yakananga, zvichiidzivirira kuti isakanganise zvakananga maforoma eingot uye zvichideredza kutadza kwechimiro kunokonzerwa nekupisa kwakanyanya. Uyezve, hunhu hwavo hwekusagadzikana hunoita kuti dzikwanise kutsungirira kukanganiswa kwemuviri uye makemikari esimbi yakanyungudutswa inopisa zvakanyanya, zvichidzivirira tsvina kuti isapinde musimbi uye zvichikanganisa kunaka kwayo.
