Kuponyedwa chitsulo kuwotcherera

Iron -, monga amadziwika, chitsulo ndi aloyi mpweya. The zili yotsirizira akhale wamkulu kuposa awiri pa zana. Malinga ndi boma lomwe aloyi ndi mpweya kusiyanitsa imvi ndi woyera mitundu ya chitsulo chosungunula. Mu mawonekedwe woyamba mpweya umakhala wa graphite, m'chigawo free, izo Mzimuyo machinability zake zabwino. Popeza osewera chitsulo woyera, amafotokozera izi boma womangidwa, ndi kovuta china chotulutsa. Kumayambiriro kwa nkhani ndi kuwala mtundu.

Kodi osewera chitsulo kuwotcherera? Tiyeni tiyambe ndi choona kuti nkhaniyi - osati abwino kwambiri mtundu wa mankhwala. Pamene kuwotcherera izo deforms ndi mosavuta ming'alu. Ichi ndi chifukwa kapangidwe wapadera wa mpweya mu fupa lothyoka ake. Wothira mafuta kuponya chitsulo, komanso anthu amene akukonza kukhudzana ndi atolankhani osiyanasiyana zikuwononga, sakhoza welded. Komabe, mitundu abwino amene chabwino grained ndi kuwala imvi mtundu. Kuwotcherera chitsulo ali mavuto: whitening ndi chifukwa zimenezi, a kwanuko kuchita kuwotcherera woyera chitsulo wosanjikiza zomwe si kongoletsani lokha palibe mankhwala; Monga tanenera kale, mapangidwe ming'alu; kuwonjezeka voteji mu zone ya kuwotcherera; china chotulutsa dziwe zitsulo kungakhale porous chifukwa mpweya amatopa ndi mapangidwe munthawi yomweyo mpweya. Choncho, ndondomeko zimenezi zimachititsa mabvuto. Koma kuwotcherera kuponya chitsulo ntchito ndithu ambiri. Iwo ali njira zitatu zikuluzikulu: ozizira ndi kutentha kwa theka.

Choyamba ndi pakalibe preheating. Cold kuwotcherera wa chitsulo chosungunula ndi zopangidwa ndi zitsulo, chitsulo kuponyedwa ndipo anapanga zitsulo sanali akakhala ndi kasakaniza wazitsulo maelekitirodi. Chinthu chachikulu ndi ichi - kupewa kutentha mu woyendera nthambi kutentha anakhudzidwa. Pakuti dzimbiri maelekitirodi ntchito choyamba elekitirodi wosanjikiza superposed awiri ang'onoang'ono ndi yaing'ono mpweya okhutira, ❖ kuyanika woonda. Amperage panthawi imeneyi sayenera upambana 90 mikuza mawu. zigawo wotsatira ali superposed maelekitirodi a m'mimba mwake wamkulu, ❖ kuyanika ikhoza kukhala wochepa thupi kapena lakuda.

ulamuliro chimodzi chofunika - mfundo zachitsulo ayenera kutsatira ndi zosokoneza pang'ono kuti kutenthetsa-anakhudzidwa zone kutentha si upambana madigiri sikisite.

Ngati kuwotcherera ayenera anachita mbali yapadera, ndiye inu mukhoza kugwiritsa ntchito chipangizo wapadera. Izi otchedwa vvertyshi - studs wapadera, amene zopangidwa ndi zitsulo wofatsa. Cholinga chawo - yolumikizana ndi zitsulo china chotulutsa ndi chitsulo. Kuwotcherera imagwiridwa choyamba, owazungulira, ndiyeno - kudacita. Pamene m'pofunika china chotulutsa zopindika aliyense akuponya, fissures ndi mfundo zina ofooka, nthawi zambiri ntchito maelekitirodi zopangidwa kasakaniza wazitsulo zochokera faifi tambala kapena mkuwa. Kulimbikitsa graphitization, iwo kuteteza zikamera wa zone ndi yotakata oyeretsa. Kuwotcherera chitsulo kunyumba makamaka amapangidwa njira ozizira. Izi zikhoza kugwiritsidwa ntchito iliyonse ya mitundu ya maelekitirodi tatchulazi.

Hot chitsulo kuwotcherera kumafuna Kutentha kwa workpiece pamaso amachita izo. Njira imeneyi imagwira amachepetsa voteji dongosolo zitsulo. Njira theka - ndi kusinthidwa otentha. Ndi zitsulo za graphitization ndi ambiri kapena m'dera Kutentha kwa kutentha zina. Njirazi zimagwiritsidwa ntchito m'njira zosiyanasiyana.

Ngati inu mukufuna kuwotcherera mbali munthu zachitsulo chosungunula, ngati ntchito njira ozizira kuwotcherera lomwe. Ngati ntchito ikuchitika pa mbewu, pamlingo mafakitale ntchito njira otentha.
