Zida za makina a ulimi 65Mn fosholo yozimitsidwa ya pulawo yosatha ntchito Chithunzi Chowonetsedwa

Zida zamakina a ulimi 65Mn fosholo yolimba yolimba yolimba yolimba

Kufotokozera Kwachidule:

Zipangizo zothandizira za makina a zaulimi, monga mapulawu ndi mafosholo, zimapangidwa ndi chitsulo chapamwamba cha boron ndipo zimatenthedwa bwino kwambiri, zomwe zimapangitsa kuti zikhale zolimba komanso zosalala. Kapangidwe kake ka fosholo kosalala kangathandize kuchepetsa kukana kwa nthaka, ndi mphamvu yolowera bwino m'nthaka komanso kuswa nthaka bwino. Chogulitsachi chimasinthidwa bwino kuti chigwirizane ndi mathirakitala akuluakulu ndipo chimagwiritsidwa ntchito kwambiri polima mozama m'minda youma ndi minda ya mpunga. Chingathandize kwambiri ulimi kugwira ntchito bwino ndikuchepetsa kugwiritsa ntchito mphamvu, zomwe zimapangitsa kuti chikhale gawo labwino kwambiri paulimi wamakono.

Fosholo ya pulawo, yomwe imadziwika kuti nsonga ya pulawo kapena nsonga ya fosholo, ndi gawo lofunika kwambiri komanso lowonongeka mwachangu pa ntchito yolima. Monga woyambitsa pulawo lonse, imadula mwachindunji nthaka ndipo imakhala ndi udindo wodula nthaka ndikuchepetsa kukana. Mapulawo ndi mafosholo abwino kwambiri samangotsimikizira kuzama kwa kulima nthawi zonse, komanso amachepetsa kwambiri kunyamula kwa thirakitala ndikuwonjezera kugwiritsa ntchito mafuta moyenera.

Mapulawo ndi mafosholo osiyanasiyana amagwiritsa ntchito chitsulo chapamwamba cha boron (monga 30MnB5 kapena zinthu zofanana) ngati substrate. Pambuyo pa njira yapadera yochizira kutentha, kuuma kwa nsonga ya fosholo kumatha kufika HRC 48-52, pomwe chogwirira cha fosholo ndi malo oikira mabowo amakhala olimba kwambiri. Khalidwe la "kulimba kunja ndi kulimba mkati" limathandiza kuti likhale lolimba kwambiri pakuwonongeka komanso kukana kusweka likayang'anizana ndi mchenga ndi miyala, zomwe zimathandiza kupewa ming'alu kapena kupindika.

Fosholo ya pulawo ya Universal: yoyenera kulima loam ndi mchenga.

Pulo lotambasuka/lokulirapo: lopangidwira ntchito yolima nthaka yolemera kapena yozama, kuwonjezera ngodya yolowera kuti nthaka igawanike bwino.

Fosholo yophikira yofanana ndi yophikira: nsonga yokhuthala ya fosholo, yoyenera kubwezeretsanso malo ouma okhala ndi miyala yambiri.

Kapangidwe ka tsamba lodzinola lokha: Popeza ntchito yolima imayamba kuwonongeka, nsonga ya fosholo imakhalabe yakuthwa, zomwe zimapangitsa kuti pakhale chiŵerengero chokhazikika cha kulima komanso kuchepetsa kugwiritsa ntchito mafuta.

Kuchiza pamwamba: Ikani pulasitala yonse yoletsa dzimbiri kuti mupewe dzimbiri panthawi yosungira ndi kunyamula.
