Chiyambi ndi Kukula kwa Calcium Aluminium Alloy

Chiyambi

M'dziko lathu, kashiamu adawoneka ngati zitsulo, zomwe zidayambanso ku imodzi mwama projekiti akuluakulu othandizidwa ndi Soviet Union kudziko lathu isanafike 1958, bizinesi yamagulu ankhondo ku Baotou. Kuphatikizapo njira yamadzimadzi cathode (electrolysis) zitsulo zopanga calcium. Mu 1961, mayeso ang'onoang'ono adapanga calcium yoyenerera.

Kukula:

Kumapeto kwa zaka za m'ma 1980 mpaka kumayambiriro kwa zaka za m'ma 1990, ndi kusintha kwabwino kwa mabizinesi ankhondo m'dzikoli ndi malingaliro a "asilikali-kwa-wamba", chitsulo cha calcium chinayamba kulowa msika wamba. Mu 2003, pamene msika wofuna kashiamu wachitsulo ukupitirira kuwonjezeka, Baotou City yakhala yaikulu kwambiri padziko lonse lapansi yopanga zitsulo za calcium, Komwe muli ndi mizere inayi yopanga kashiamu ya electrolytic, yomwe imakhala ndi mphamvu yopangira matani 5,000 a zitsulo zachitsulo ndi zinthu.

Kutuluka kwa Calcium Aluminium Alloy:

Chifukwa cha kusungunuka kwa kashiamu wachitsulo (851 ° C), kashiamuyo amawotchera akamawonjezera chitsulo m'madzi amtovu osungunuka amafika pafupifupi 10%, zomwe zimapangitsa kuti pakhale mitengo yokwera, kuwongolera kapangidwe kake, komanso nthawi yayitali. kugwiritsa ntchito mphamvu nthawi. Choncho, m'pofunika kupanga aloyi ndi zitsulo zotayidwa ndi zitsulo kashiamu kuti asungunuke pang'onopang'ono wosanjikiza ndi wosanjikiza. Maonekedwe a calcium aluminiyamu aloyi ndi ndendende umalimbana kuthetsa vutoli pokonzekera ndondomeko ya lead calcium aluminium alloy.

Kupanga kashiamu aluminium alloy ndi njira yosungunula ndikusakaniza mu vacuum state pogwiritsa ntchito kutentha kwakukulu molingana ndi chiŵerengero cha chitsulo cha calcium ndi zitsulo zotayidwa.

Gulu la Calcium Aluminium Alloy:

Kashiamu zotayidwa aloyi zambiri wachinsinsi 70-75% kashiamu, 25-30% zotayidwa; 80-85% calcium, 15-20% zotayidwa; ndi 70-75% calcium 25-30%. Ikhozanso kusinthidwa malinga ndi zofunikira. Calcium aluminiyamu alloy ali ndi zitsulo zonyezimira, chilengedwe chamoyo, ndipo ufa wabwino ndi wosavuta kuyaka mumlengalenga. Amagwiritsidwa ntchito makamaka ngati alloy master, kuyenga ndi kuchepetsa wothandizira pakusungunula zitsulo. Zogulitsazo zimaperekedwa ngati midadada yachilengedwe, komanso zitha kusinthidwa kukhala zinthu zamitundu yosiyanasiyana malinga ndi zosowa za ogwiritsa ntchito.

Gulu la Quality of

Monga master alloy, zofunika zamtundu wa calcium aluminium alloy ndizovuta kwambiri. (1) Zomwe zili mu kashiamu yachitsulo zimasinthasintha pang'ono; (2) Alloy sayenera kukhala ndi tsankho; (3) Zonyansa zovulaza ziyenera kuyendetsedwa mkati mwazoyenera; (4) Pasakhale makutidwe ndi okosijeni pamwamba pa alloy; Panthawi imodzimodziyo, kupanga, kulongedza, kuyendetsa ndi kusungirako calcium aluminium alloy chofunika Njirayi iyenera kuyendetsedwa mosamalitsa. Ndipo opanga ma calcium-aluminium alloys omwe timapereka ayenera kukhala ndi ziyeneretso zovomerezeka.

Mayendedwe ndi kusunga

Mankhwala a calcium aluminium alloy amagwira ntchito kwambiri. Ndiosavuta kutulutsa okosijeni ndikuyaka mosavuta mukakumana ndi moto, madzi komanso kukhudzidwa kwambiri.

1. Kuyika

Kashiamu zotayidwa aloyi waphwanyidwa molingana ndi mfundo zina, izo zimayikidwa mu thumba pulasitiki, kulemera, wodzazidwa ndi argon mpweya, kutentha losindikizidwa, ndiyeno kuika mu ng'oma chitsulo (international standard ng'oma). Mtsuko wachitsulo uli ndi ntchito zabwino zopanda madzi, zopanda mpweya komanso zotsutsana ndi zotsatira.

2. Kutsegula ndi kutsitsa

Pakukweza ndi kutsitsa, forklift kapena crane (chokweza magetsi) chiyenera kugwiritsidwa ntchito pokweza ndi kutsitsa. Ng'oma zachitsulo siziyenera kukulungidwa kapena kuponyedwa pansi kuti chikwamacho chisawonongeke komanso kuti chitetezo chiwonongeke. Zinthu zowopsa kwambiri zitha kuyambitsa kuyaka kwa aloyi ya calcium aluminium mu mgolo.

3. Mayendedwe

Pa zoyendera, yang'anani kwambiri kupewa moto, kutsekereza madzi komanso kupewa zotsatirapo.

4. Kusungirako

Nthawi ya aluminiyamu ya calcium aluminium alloy ndi miyezi itatu osatsegula mbiya. Aluminiyamu aloyi wa calcium sayenera kusungidwa poyera, ndipo asungidwe m’malo owuma, osungiramo mvula. Mukatsegula chikwama choyikamo, chiyenera kugwiritsidwa ntchito momwe mungathere. Ngati aloyi sangathe kugwiritsidwa ntchito panthawi imodzi, mpweya wa m'thumba uyenera kutha. Mangani pakamwa molimba ndi chingwe, ndikubwezeretsanso mu mgolo wachitsulo. Kusindikiza kuti muteteze alloy oxidation.

5. Ndizoletsedwa kuphwanya kashiamu-aluminium alloy mu ng'oma zachitsulo kapena matumba oyikamo okhala ndi calcium-aluminium alloy kuti apewe moto. Kuphwanya kwa calcium aluminium alloy kuyenera kuchitika pa mbale ya aluminiyamu.
