Okwangoku, baninzi kakhulu abavelisi bemibhobho yentsimbi engenamthungo kwimarike. Xa ulungiselela ukuthenga imibhobho engenamthungo, akungabazeki ukuba kufuneka ukhethe umthengisi wepayipi othembekileyo ongenamthungo, ukuze wonke umntu angakhathazeki malunga nomgangatho wemveliso yempahla. Kukho neziqinisekiso ezisisiseko ekusetyenzisweni kwangempela, ngoko ke ungakhetha njani okulungileyoumthengisi umbhobho wentsimbi engenamthungo?

Kubalulekile ukukhetha umboneleli ofanelekileyo wombhobho wentsimbi ongenamthungo ngokusekelwe kwiimfuno zomntu ngamnye zezicelo. Umnikezeli wepayipi wensimbi ongenamthungo ubonelela ngeemveliso ezisemgangathweni ngexabiso eliphantsi. Oyena mvelisi ungcono utyala imali eninzi kunye nexesha ekuqhubeni uphando lokuphuhlisa iimveliso zentsimbi. Kukho izinto eziphambili omele uziqwalasele xa ukhetha umthengisi wemibhobho yentsimbi engenamthungo.
1. Ilayisensi kunye namava omthengisi
Okokuqala, kufuneka uhlolisise ilayisenisi yomthengisi xa ukhetha umthengisi wepayipi yensimbi engenamthungo. Inkampani enelayisensi iqeqeshe kunye neengcali ezinamava ukubonelela ngemveliso esemgangathweni kumntu wonke. Ungajonga kwakhona ilayisenisi kwi-portal esemthethweni yenkampani. Kwangaxeshanye, kuya kufuneka uqwalasele ukuba ngaba inkampani inamava endle okanye hayi. Iingcali ezinamava ziyaqonda iimfuno zomxhasi kwaye zibonelela ngenkonzo efanelekileyo ngexesha elifutshane.

2. Jonga izixhobo
Ngaphambi kokuba uthenge umbhobho wensimbi ongenamthungo kwizicelo zakho, kufuneka uqwalasele umgangatho wezinto eziphathekayo. Izinto eziphathekayo ziyakwazi ukugcina imichiza kunye nokutshisa ukushisa okunika amandla kwiindawo. Abasebenzisi kufuneka bahlole ukuhambelana kwezinto eziphathekayo kunye nezisombululo zamakhemikhali ezidlula kumbhobho. Ukuba uthenga izinto ezisemgangathweni eziphantsi ezonakalisa isakhiwo sangaphakathi samacandelo. Ke kuya kufuneka ujonge umgangatho wezinto ezibonakalayo ngaphambi kokuba uthenge isicelo sakho.

3. Qwalasela iindleko zombhobho wentsimbi ongenamthungo
Xa ujonge ukuthenga umbhobho wentsimbi ongenamthungo kufuneka ucinge ngexabiso lemveliso. Iindleko zamacandelo ziyahluka ngokusekelwe kumgangatho, ubukhulu, kunye nabanye. Kufuneka uthelekise iindleko kunye nomgangatho ovela kumboneleli owahlukileyo kwaye ukhethe ofikelelekayo ohambelana nohlahlo lwabiwo-mali lwakho. Ababoneleli abaninzi babonelela ngeemveliso ezingabizi kakhulu kubathengi.

4. Qwalasela umgangatho wemveliso
Umgangatho yinto ephambili ekufuneka uyiqwalasele xa uthenga iimveliso zesicelo sakho. Kukho uluhlu olukhulu lomenzi kwimarike. Bambalwa kubo abanamava ngoko ke babonelela ngeemveliso ezikumgangatho ophantsi kubathengi. Kuya kufuneka ujonge umgangatho wemveliso kwaye ukhethe ababoneleli abathembekileyo abalandela iinkqubo zokulawula umgangatho obalaseleyo kwinqanaba ngalinye lenkqubo yophuhliso lwamalungu.

5. Khangela indlela yokuvavanya
Kufuneka uhlolisise indlela yokuvavanya xa uthenga umbhobho wensimbi ongenamthungo. Ukhuseleko luqinisekiswa yinkqubo efanelekileyo yokuvavanya. Abavelisi abahamba phambili bemibhobho yensimbi engenamthungo banendawo yokuvavanya ngaphakathi kwindlu yokuqhuba iimvavanyo ezininzi kwiimveliso zabo zetsimbi. Uvavanyo luqhutywa ngamaxesha aqhelekileyo ngokwemigangatho yoshishino.

Ixabiso lemihla ngemihla letyhubhu engenamthungo ibonisa into eguqukayo. Ke ngoko, xa abanye abathengi bethenga ngobungakanani obukhulu, kufuneka bathathele ingqalelo kwindlela yexabiso lemarike ngexesha lokwenyani, ukuze bafumane inqanaba elineendleko eziphezulu zokuthenga. Ngokuqhelekileyo, abavelisi bemibhobho yensimbi engenamthungo banikela ingqalelo kwezinye iiwebhusayithi imihla ngemihla kwaye baqhube uhlalutyo olufanelekileyo kwiingcaphuno zemibhobho yensimbi kwiwebhusayithi. Ukwazi ukwenza uhlalutyo lwentelekelelo ehambelana nexabiso lemarike kwiveki ezayo, kwaye uqonde intsingiselo yexabiso elizayo ukusuka kumaxabiso aqikelelweyo kunye ahlalutyiweyo. Kubathengi abawaziyo ixabiso lemibhobho yensimbi engenamthungo kwiimarike, banokukhetha ixesha elifanelekileyo lokuthenga imibhobho ngamaxabiso aphantsi, ngokwenene anokugcina iindleko ezininzi kwiiprojekthi ezintsha.

Inkqubo yokuveliswa kweemibhobho zensimbi ezingenamthungo zinokwahlulwa zibe ziindidi ezimbini: umzobo obandayo kunye ne-hot-rolling. Inkqubo yokuvelisa imibhobho yentsimbi engenamthungo epholileyo eqengqelekayo ngokuqhelekileyo inzima ngakumbi kuneyokuqengqeleka okushushu. Kuvavanyo lokulinganisa, ukuba umphezulu awuphenduli kwiintanda, ityhubhu ejikelezileyo iya kunqunyulwa ngumatshini wokusika kwaye unqunywe kwi-billet kunye nobude obumalunga nemitha enye. Emva koko faka inkqubo yokukhupha. I-annealing kufuneka ifakwe kwi-acidic liquid. Xa ukhetha, qaphela ukuba kukho amaqamza amaninzi kumphezulu. Ukuba kukho amaqamza amaninzi, oko kuthetha ukuba umgangatho wombhobho awukho kumgangatho.

Ngenkangeleko, umbhobho wentsimbi ongenamthungo opholileyo umfutshane kunokoumbhobho wentsimbi ongenamthungo oshushu. Ubukhulu bodonga lombhobho wentsimbi ongenamthungo oqengqelekayo buncinci kunobo bombhobho wentsimbi ongenamthungo oqengqelekayo, kodwa umphezulu ubonakala uqaqambile kunombhobho wentsimbi ongenamthungo ongqindilili, kwaye umphezulu awuninzi kakhulu. Ubuninzi boburhabaxa, kwaye akukho burrs zininzi kakhulu kwi-caliber, umbhobho onjalo ongenamthungo unomgangatho ophezulu wokuqatshelwa komgangatho.
