Cholimira cholimba komanso chogwira ntchito bwino

Kufotokozera Kwachidule:

【Chida Champhamvu Cholima, Ubwino Wokonzedwa】 Chopangidwa ndi chitsulo cha manganese champhamvu kwambiri kudzera mu kuponyera molondola komanso kutentha, zomwe zimapangitsa kuti zikhale bwino pakati pa kuuma ndi kulimba. Malo opindika a pulawo amakonzedwa bwino kuti nthaka ilowe bwino komanso kuti isagwe, zomwe zimapangitsa kuti nthaka isweke bwino komanso kuti iphimbe bwino. Imabwera ndi mabowo olumikizirana, omwe amagwirizana ndi makina akuluakulu a ulimi. Chophimba cholimba choletsa dzimbiri chimatsimikizira kuti chimakhala chowala komanso chogwira ntchito bwino ngakhale m'malo ovuta a ulimi, zomwe zimathandiza kulima bwino masika ndi kubzala m'dzinja.

Chomera ichi ndi chowonjezera chofunikira kwambiri chomwe chapangidwira ulimi wamakono, chokhudza nthaka mwachindunji ndikumaliza gawo lovuta kwambiri la ulimi. Chopangidwa pogwiritsa ntchito ukadaulo wapamwamba komanso sayansi ya zinthu, chimatsimikizira kuti nthaka siiwonongeka kwambiri komanso kuti nthaka isamasweke bwino komanso kuti ndi yotsika mtengo komanso yosavuta kusintha, zomwe zimapangitsa kuti ikhale chisankho chabwino kwambiri chothandizira ulimi kugwira ntchito bwino komanso kuchepetsa ndalama zogwirira ntchito kwa nthawi yayitali.

Zipangizo: Zopangidwa ndi chitsulo champhamvu kwambiri (monga 65Mn, 60Si2Mn), ndipo zimayikidwa bwino kwambiri kuti zithetse kuuma kwambiri (HRC 48-55) pamlingo wapamwamba, pomwe zimasunga kulimba kwa fosholo, zomwe zimapangitsa kuti ikhale yolimba komanso yosawonongeka.

Njira: Mphepete mwa njira iyi imatha kuumitsidwa mwapadera (monga carburizing, high frequency quenching) kapena kulumidwa ndi ndodo zolumikizira zolimba/ndodo zolimba, zomwe zimakulitsa kwambiri moyo wa ntchito pansi pa mikhalidwe yovuta monga nthaka yamchenga ndi ya miyala ndi nthaka yolimba, ndikuwonjezera moyo wa ntchito ndi nthawi 2-3 poyerekeza ndi masamba wamba a pulawo.

Mitundu ya Mbewu: Yoyenera kulimidwa m'munda wouma tirigu, chimanga, soya, thonje, ndi malo ouma musanayambe kulima mpunga.

Magawo Olima: Amagwiritsidwa ntchito makamaka polima mozama nthawi ya autumn, kulima m'masika, ndi kuchotsa ziputu, zomwe zimapangitsa kuti mbeu zibzalidwe bwino.

Makina Othandizira Zaulimi: Mitundu yosiyanasiyana ya mapulawu ogwirira ntchito kapena opachikidwa, mapulawu osinthika, ndi mapulawu osinthika m'lifupi.
