Masamba obwezerera zitsulo a 65Mn abwino kwambiri, okonzedwa ndi kutentha komanso okhuthala.

Kufotokozera Kwachidule:

Masamba olima awa opangidwa ndi makina a ulimi amapangidwa ndi chitsulo cha boron chapamwamba pogwiritsa ntchito kupondaponda kolondola. Thupi la tsamba limazimitsidwa kutentha kwambiri, kukhala ndi mphamvu komanso kusinthasintha, kukana kupotoka komanso kupewa kusweka. Ngodya yolowera yokonzedwa bwino mwasayansi imachepetsa kumamatira kwa nthaka, zomwe zimapangitsa kuti ntchito ikhale yosavuta. Kaya ndi kulima m'malo ouma kapena kulima mozama, masambawo amasunga kuthwa kwawo kwa nthawi yayitali, zomwe zimapangitsa kuti moyo wawo ukhale wautali.

Chopangidwa ndi chitsulo chokhuthala cha 65Mn champhamvu kwambiri, chimatenthedwa ndi kutentha, zomwe zimapangitsa kuti chikhale cholimba kwambiri komanso chosatha kutha. Kapangidwe kake kolunjika komanso kopindika kamalola kudula mosavuta dothi lolimba, zomwe zimapangitsa kuti nthaka ikhale yolimba kwambiri. Izi zimachepetsa kwambiri kukana kugwira ntchito kwa thirakitala ndipo zimathandizira bwino kubwezeretsa nthaka, zomwe zimapangitsa kuti ikhale chisankho chabwino kwambiri pantchito zouma komanso za mpunga.

Tsamba lotila ndi gawo lofunikira kwambiri lothandizira lomwe limagwiritsidwa ntchito ndi makina a zaulimi monga mathirakitala. Limagwiritsidwa ntchito makamaka pantchito za m'munda polima, kudula mizati, kupalira udzu, ndi kuphwanya ziputu. Monga gawo lotha ntchito, limamasula bwino nthaka, limathandizira kuti nthaka ikhale yolimba, ndipo limadula ndikuyika udzu ndi ziputu m'nthaka kudzera mu kulima kozungulira kapena kuswa nthaka, zomwe zimapangitsa kuti pakhale malo abwino oti mbewu zibzalidwe pambuyo pake. Chogulitsachi nthawi zambiri chimapangidwa ndi chitsulo champhamvu kwambiri kuti chipirire kukhudzidwa kwakukulu ndi kuwonongeka m'malo ovuta a nthaka.

Kuti zitsimikizire kulimba pansi pa mikhalidwe yovuta yogwirira ntchito, tsamba lobwezeretsa limagwiritsa ntchito chitsulo chapamwamba kwambiri cha alloy spring steel (monga 60Si2Mn, 60Si2MnA, 28MnSiB, ndi 65Mn) ngati maziko ake. Ukadaulo wopangira zinthu umagwiritsidwa ntchito popanga, kuphatikiza ndi chithandizo cha kutentha cha martensitic, kuti ulamulire mwamphamvu kuuma kwa chinthucho mkati mwa HRC 42-48 (opanga ena amagwiritsa ntchito HRC45±3). Izi zimapangitsa kuti zikhale ndi mawonekedwe abwino kwambiri a makina, kuphatikiza kuuma kwakukulu ndi kulimba bwino, zomwe zimathandiza kupewa kusweka ndi kuwonongeka msanga.
