Shin bututun karfen carbon bututun karfe ne mai waldadi?

Carbon karfe bututu ba welded karfe bututu. Carbon karfe bututu yana nufin takamaiman abu na karfe bututu ne carbon karfe, wanda ke nufin baƙin ƙarfe-carbon gami da carbon abun ciki Wc kasa da 2.11%. Baya ga carbon, gabaɗaya ya ƙunshi ƙaramin adadin silicon, manganese, phosphorus, sulfur da sauran ƙazanta. da sauran abubuwan da suka rage. Bugu da ƙari, wannan bututun ƙarfe na carbon yana da nau'ikan aikace-aikace, galibi ana amfani da su a cikin gine-gine, gadoji, layin dogo, motoci, jiragen ruwa da masana'antun kera injuna daban-daban.

Carbon karfe bututu za a iya raba carbon karfe welded bututu da carbon karfe sumul bututu bisa ga masana'antu tsari.

Carbon karfe welded bututu za a iya raba uku iri: madaidaiciya kabu submerged baka welded karfe bututu, karkace welded karfe bututu, da high-mita madaidaiciya kabu welded karfe bututu bisa ga forming hanya na weld kabu.
Bututun welded mai tsayi: Weld ɗin yana cikin layi madaidaiciya, don haka ana kiransa bututu mai walƙiya madaidaiciya.
Karkataccen bututu mai walda: Kabu mai walda yana cikin siffa mai karkace, wanda ake kira karkace walda.

Hanyoyin walda guda uku suna da nasu fa'ida da rashin amfani, kuma wanne za a yi amfani da su ya dogara da abubuwan ƙira. Ana iya amfani da bututun ƙarfe na ƙarfe mai waldaran ƙarfe a wurare da yawa, kamar samar da ruwa da ayyukan magudanar ruwa, ayyukan tarawa, bututun najasa, watsa mai da iskar gas, ginshiƙai da sauran ayyuka. Hanyar walda na yanzu na carbon karfe welded karfe bututu ne yafi mai gefe biyu submerged baka waldi. Wannan hanyar walda tana da inganci mai inganci, ingancin walda mai inganci da santsi.

Carbon karfe hanyar samar da bututu maras kyau:

Carbon karfe ba sumul bututu sun kasu kashi biyu iri: zafi-birgima (extruded) sumul karfe bututu da sanyi-ja (birgima) sumul karfe bututu saboda daban-daban masana'antu tafiyar matakai. An raba bututun sanyi (birgima) zuwa nau'i biyu: bututu masu zagaye da bututu masu siffa ta musamman.

1. Hot-birgima (extruded) carbon karfe sumul karfe bututu: zagaye tube billet → dumama → huda → uku-roll giciye mirgina, ci gaba da mirgina ko extrusion → tube cire → girman (ko rage) → sanyaya → mikewa → ruwa matsa lamba gwajin ( ko gano aibi) → alama → ajiya

Danyen kayan da za a yi birgima maras sumul bututun bututun bututu ne, kuma za a yanke tayin ta hanyar yankan inji don shuka billet mai tsayin kusan mita 1, sannan a kai shi zuwa tanderun ta hanyar bel mai ɗaukar nauyi. Ana ciyar da Billet a cikin tanderun don zafi, zafin jiki yana kusan 1200 digiri Celsius. Man fetur shine hydrogen ko acetylene. Kula da zafin jiki a cikin tanderun baturi ne mai mahimmanci. Bayan bututun zagaye ya fita daga cikin tanderun, dole ne a huda shi ta hanyar matsi. Gabaɗaya, mafi yawan mai huda shine mazugin mazugi. Irin wannan sokin yana da ingantaccen samarwa, ingancin samfur mai kyau, haɓaka diamita mai girma, kuma yana iya sa nau'ikan ƙarfe iri-iri. Bayan an huda, billet ɗin zagayen yana jujjuyawa a jere, a ci gaba da birgima ko fidda shi da birgima guda uku. Bayan extrusion, ya kamata a cire tube don yin girma. Girman ramukan jujjuyawar mazugi mai tsayi a cikin billet don samar da bututu. Diamita na ciki na bututun ƙarfe an ƙaddara ta tsawon tsayin diamita na waje na diamita na na'ura mai ƙima. Bayan da bututun karfe ya yi girma, ya shiga cikin hasumiya mai sanyaya kuma an sanyaya shi ta hanyar fesa ruwa. Bayan an sanyaya bututun karfe, za a daidaita shi. Bayan an daidaita, ana aika bututun ƙarfe zuwa ga gano lahani na ƙarfe (ko gwajin ruwa) ta bel mai ɗaukar nauyi don gano aibi na ciki. Idan akwai tsagewa, kumfa da sauran matsaloli a cikin bututun ƙarfe, za a gano su. Bayan ingancin duban bututun ƙarfe, ana buƙatar zaɓi mai ƙarfi na hannu. Bayan ingancin dubawa na bututun ƙarfe, fenti lambar serial, ƙayyadaddun bayanai, lambar ƙirar samarwa, da dai sauransu tare da fenti. Kuma an ɗaga shi cikin sito ta crane.

2. Cold jawo (birgima) carbon karfe sumul karfe bututu: zagaye tube blank → dumama → perforation → annealing → pickling → man fetur (jan karfe plating) → Multi-wuce sanyi sanyi (sanyi mirgina) → blank tube → zafi magani → Madaidaici → Gwajin hydrostatic (gano aibi) → alama → ajiyar kaya
