Zvose simbi uye simbi yakakandwa isimbi yakakurumbira, asi inowanzoshandiswa zvakasiyana zvikuru.Chinhu chakakosha chinosiyanisa imwe kubva kune imwe ndechekuti yakawanda kabhoni imwe neimwe ine, uye kusvika padiki, yakawanda sei silicon.Kunyange zvazvo izvi zvingaita semusiyano wakajeka, zvine zvazvinoreva zvikuru pazvivakwa uye kushandiswa kwesimbi nesimbi.
Cast Iron: Mabhenefiti uye Mashandisirwo
Kufanana nesimbi, simbi yakakandwa isimbi-based alloy.Zvisinei, kuti ionekwe sesimbi yakakandwa, simbi yacho inofanirwa kunge iine 2-4% kabhoni yemukati uye 1-3% yesilicon yemukati nehuremu.Iyi chemistry inopa simbi yakakandwa ine huwandu hwezvinhu zvinobatsira:
Simbi yakakandwa inogona kunyatso kupatsanurwa kuita grey iron, simbi chena, ductile iron, uye simbi inogoneka.Mhando yega yega inotarisana nekuvandudza zvimwe zvivakwa zveimwe application, senge kuomarara kwepamusoro mune chena cast iron.
Iko kushandiswa kwesimbi yakakandwa kwakafaranuka, asi heano mashoma akakosha mashandisirwo:
Kanda iron frying pani uye zvimwe zvekubikira
Injini yemotokari inovhara, mabhureki disks, uye zvimwe zvakawanda zvikamu
Magedhi efenzi yekugara, zvigadziko zvemwenje zvekushongedza, zvinhu zvemoto, uye zvimwe midziyo
Mavharuvhu, mafittings, uye manhole anovhara mumvura netsvina yekushandisa
Maketani, magiya, shafts, zvinongedzo, uye zvimweSimbi: Mabhenefiti uye Mashandisiro
Simbi: Benefits uye Mashandisirwo
Zvakafanana nesimbi yakakandwa, masimbi ane iron-based alloys ane mashoma akasiyana mapoka.Masimbi ese ane kabhoni yemukati inosvika 2% nehuremu uye anogona kupatsanurwa kuita kabhoni simbi kana alloy simbi.
Zvinogona kugovaniswazve kuita yakaderera-kabhoni simbi, simbi isina tsvina, simbi yemidziyo, simbi ine microalloyed, nezvimwe.Kunyange izvi zvichigona kupa akawanda mabhenefiti, senge kusimba kwepamusoro uye kuramba kwemarara kubva kune simbi isina tsvina, chinyorwa ichi chinotarisa pane yakakandwa simbi alloys seiya inotsanangurwa neASTM A148.
Sezvo simbi yakakandwa ichidhura kupfuura simbi yakakandwa, zvakanakira zvikuru pane simbi yakakandwa ndeiyi:
Tensile Strength - Zvichienderana nealloy inoshandiswa, simbi yakakandwa inogona kunge iine simba rakanyanya kusimba kupfuura simbi yakakandwa.
Kuoma / Kusimba - Pasi pekunetseka kwakanyanya, simbi inogona kukanganisa (kwechinguva kana zvachose) pasina kuputsa.Kunyange izvi zvichireva kuomarara kushoma mune mamwe maapplication, zvinoderedza mukana wekutsemuka uye zvinoreva kuita zvirinani kuita.
Weldability - Zvichienderana nealloy inoshandiswa, simbi inopa zvakanaka weldability, nepo simbi yakakandwa inonetsa kupinza pasina kukonzera kutsemuka.
Nepo kugadzira, kukungurutsa, uye kukanda zvese zvinogoneka kune zvigadzirwa zvesimbi, mamwe makiyi ekushandisa akatarisana nesimbi yakakandwa ndeaya:
Chitima mavhiri emotokari, mafuremu, uye mabhodhoro
Michina yemigodhi, midziyo yekuvaka, uye marori anorema
Heavy duty pombi, mavharuvhu, uye fittings
Turbocharger, zvivharo zveinjini, uye zvimwe zvikamu zvemotokari
Turbines nezvimwe zvikamu mumagungano emagetsi echiteshi
Yakagadzirwa nesimbi uye zvigadzirwa zvesimbi :
Cast iron zvirokwazvo iri nyore uye yakachipa kumuchina pane yakakandwa simbi, asi machinability inosiyana zvakanyanya pakati pealloys.Saka kana iwe uri kugadzira chigadzirwa chinoda machining marefu maoperation, zvingave zvakakosha kuti uongorore alloys aripo kuti uwane imwe ine zvirinani machinability.
Asi kunyangwe iwe wakaganhurirwa kune zvimwe zvakaoma zvinhu, ine ruzivo, yepasi-yepasi muchina shopu inogona kuderedza machining nguva kuchengetedza pamitengo yekugadzira.Ngatipei nekukurumidza, akavimbika machining masevhisi emakambani ako akasiyana zvinhu uye zvigadzirwa zvemhando.
