Babban dalilin lalacewar rufi akan farfajiyar zoben tanderu shine yanayin aiki na shigar murhun murhu galibi yana da tsauri. Kodayake akwai tsarin sanyaya ruwa, ba zai iya tabbatar da cewa fenti mai ruɓi yana aiki a cikin yanayin zafin ƙasa ba. Wannan yafi yawa saboda waɗannan dalilai:

1. Haɗin da ke haifar da wucewa ta cikin zoben makera yana da amsawar fata, wato, yanzu an fi mai da hankali kan farfajiyar bututun tagulla. Mafi girman mitar da aka jawo yanzu, mafi girman girman halin yanzu. Sabili da haka, zafin tanderun zoben jan ƙarfe yana mai da hankali akan farfajiya, kuma zafin zafin farfajiyar da ke hulɗa da fenti mai ruɓi yana da yawa fiye da zafin jiki na sashi a cikin bututun tagulla wanda ke hulɗa da ruwan sanyaya. Ko da a ƙarƙashin yanayin sanyaya ruwa na yau da kullun, ana sarrafa zafin zafin ruwa mai fitarwa a 50-60 ° C, kuma zafin saman bututun jan ƙarfe zai wuce 80 ° C.

2. The conduction zafi na narkakkar karfe a cikin makera. Kauri mai kauri na sabon tanderun zai iya hana zafin karfen da aka narke a cikin tanderun ya koma saman zoben tanderu. Duk da haka, tare da saurin ɓarna na rufin murhu a cikin lokaci na gaba, rufin ya zama mafi ƙanƙanta a cikin lokaci na gaba, kuma zafin da ƙarfe da aka narkar da shi zuwa saman zobe na tanderu ya fi na sabon rufin murhu. Hakikanin ma’aunin ma’aunin yana nuna cewa zafin zazzabin slurry Layer a cikin zoben tanderu yana kusa da 80 ° lokacin da rufin ya kasance sabo (kaurin tanderun ya kai kusan 15cm), kuma zafin zafin murƙushewa a cikin zobe na tanderu ya tashi zuwa kusa da 200 ° C a ƙarshen lokacin rufin (kaurin ya kusan 5cm). A wannan lokacin, fenti na yau da kullun ya zama carbonized kuma ya gaza.

3. Yawan sanyaya ruwan sanyaya yana raguwa, wanda galibi ke haifar da tasirin ingancin ruwa. Ruwan sanyaya yana da saukin kaiwa a yanayin zafi, musamman a yankunan arewa da na yamma inda ingancin ruwa ke da wuya. Sanya ƙimar ruwa yana shahara, yana toshe bututu na jan ƙarfe, rage matsin lamba na ruwa, ƙarfin sanyaya, da ƙara yawan zafin jiki, wanda hakan yana hanzarta haɓakawa. . Lokacin da wannan ya faru, zafin zafin saman bututun jan ƙarfe zai tashi cikin sauri, kuma fenti na yau da kullun zai zama carbonized kuma ya lalace cikin ɗan gajeren lokaci.
