fakitale mwachindunji zogulitsa kanasonkhezereka baling tepi

Iron kulongedza lamba amadziwikanso kuti chitsulo kulongedza lamba (dzina la akatswiri limatchedwanso kanasonkhezereka kulongedza lamba). Chifukwa chitsulo n'zosavuta dzimbiri mu mpweya ndi madzi, ndi dzimbiri mlingo wa nthaka mu mlengalenga isoly 1/15 wa dzimbiri mlingo wa dzimbiri. zitsulo mumlengalenga, kanasonkhezereka zitsulo mbale amatetezedwa dzimbiri ndi wosanjikiza pang'ono kanasonkhezereka.Choncho, kanasonkhezereka ntchito mu pepala chitsulo, choncho amatchedwa kanasonkhezereka kulongedza lamba.

Kugwiritsa ntchito lamba wachitsulo: bokosi lamatabwa, bolodi lopaka utoto, chitsulo chachitsulo, mbale yachitsulo, chingwe chachitsulo, chitoliro chowotcherera, aluminium ingot, ingot ya magnesium, ma CD a zinc ingot.

Mphamvu ya njira zosiyanasiyana zopangira malamba pa lamba wonyamula:
Chifukwa lamba wonyamulira wotenthetsera umapangidwa pamzere wamadzi otentha, umapangidwa ndi kulowetsedwa kosalekeza komanso kopitilira muyeso wotentha wothira zinc, ndipo mbale yachitsulo imatenthedwa ndikuzimitsidwa kwakanthawi kochepa, kotero kuti kupondaponda kwake kumakhala koipitsitsa kuposa kwa. mbale ozizira adagulung'undisa original.Tepi yonyamula ma elekitiroti samakhudzidwa ndi kutentha, kuziziritsa ndi kutentha kwina pakuyika, chifukwa chake imakhala ndi ntchito yofananira ngati mbale yoziziritsa yoyambira.Mugawo lake la malata, mulibe wosanjikiza wosalimba wa iron-zinc alloy.The ductility of kanasonkhezereka wosanjikiza ndi zabwino, koma chifukwa cha pamwamba porosity ndi mphamvu zochepa, n'zosavuta kukanda ndi kutenga youma utoto ndi kuipitsa zina.
