Menene babban carbon karfe?

Babban Carbon Karfe (High Carbon Karfe) wanda aka fi sani da kayan aiki Karfe, Abubuwan Carbon daga 0.60% zuwa 1.70%, quenching da tempering.Hammers da crowbars an yi su da 0.75% carbon karfe;yankan kayan aikin kamar drills, taps da reamers an yi su daga 0.90% zuwa 1.00% carbon karfe.
Fuskar waya ta galvanized karfe mai santsi, santsi, babu fasa, gidajen abinci, prickles, scars da tsatsa.Layin galvanized ɗin bai dace ba, mannewa mai ƙarfi, juriya mai ɗorewa, kyakkyawan ƙarfi da elasticity.

Tauri da ƙarfin babban ƙarfe na carbon ya dogara ne akan adadin carbon a cikin bayani, kuma yana ƙaruwa tare da adadin carbon a cikin bayani.Lokacin da abun ciki na carbon ya wuce 0.6% , taurin baya karuwa, amma yawan adadin carbide ya karu, juriya na lalacewa na karfe yana ƙaruwa kadan, kuma filastik, taurin kai da elasticity suna raguwa.

Don wannan, sau da yawa bisa ga yanayin amfani da ƙarfin ƙarfe, ƙarfin da ya dace don zaɓar karfe daban-daban.Misali, don yin ɓangaren bazara ko na bazara tare da ƙaramin ƙarfi, zaɓi 65 # babban ƙarfe na carbon tare da ƙananan abun ciki na carbon.General high carbon karfe za a iya amfani da lantarki tanderu, bude hearth, oxygen Converter samar.Za'a iya amfani da mafi girman inganci ko buƙatun inganci na musamman a narkewar tanderun lantarki tare da ƙyanƙyashe mai amfani ko lantarki, mai gyara slag.

A cikin narkewa, abubuwan da ke tattare da sinadarai, musamman abubuwan da ke cikin sulfur da phosphorus, ana sarrafa su sosai.Domin rage rarrabuwa da inganta isotropic dukiya, ingot za a iya hõre high zafin jiki diffusion annealing (musamman da muhimmanci ga kayan aiki karfe).Lokacin aiki mai zafi, ana buƙatar dakatar da ƙirƙira (mirgina) zafin jiki na ƙarfe na hypereutectoid ya zama ƙasa (kimanin 800 ° C).Bayan ƙirƙira da birgima, ya kamata a guji hazo na babbar hanyar sadarwa ta carbide.Hana decarburization surface a lokacin zafi magani ko zafi aiki (musamman da muhimmanci ga spring karfe).Lokacin aiki mai zafi, yakamata a sami isasshen matsi don tabbatar da inganci da aikin sabis na ƙarfe.
