Siab- cov hlua hlau carbon hlau yog qhov nkag siab rau cov thermal hloov pauv uas hloov lawv cov qauv crystalline thiab tus cwj pwm tensile. Los ntawm cov kua -nitrogen kub ntawm cryogenic thauj mus rau qhov kub siab heev ntawm foundry cranes, kev nkag siab 'Thermal Integrity' yog qhov tseem ceeb rau kev muaj sia nyob.

Cryogenic Brittleness (DBTT):

Thaum kub hauv qab -30 degree, carbon steel nkag mus rau 'Ductile- mus rau -Brittle Transition' cheeb tsam. Nyob rau hauv cov cheeb tsam no, ib txoj hlua yuav tuav nws lub zog zoo li qub tab sis poob nws qhov kev cuam tshuam toughness, ua rau 'shatter tsis ua hauj lwm' nyob rau hauv dheev shock loads. Rau kev ua haujlwm hauv Arctic, SOLITE muab tshwj xeeb qis-kub alloys nrog nce Manganese thiab Nickel cov ntsiab lus los khaws cov ductility.

Qhov kub thiab txias degradation:

Ntawm qhov kawg ntawm qhov spectrum, kub siab tshaj 200℃pib 'Annealing,' uas mus tas li softens cov hlau thiab txo nws lub zog tensile. Tsis tas li ntawd, cov roj txheem txheem-raws li lubricants yuav liquefy thiab tawm ntawm lub hauv paus ntawm qhov kub thiab txias.

Technical Countermeasures:

Rau cov cua sov- cov ntawv siv hnyav, peb siv Independent Wire Rope Cores (IWRC) los tiv thaiv cov tub ntxhais hluas tawg thiab siv siab -kub khoom- zaj duab xis lubricants (xws li Molybdenum Disulfide) uas tswj lawv cov lubrication mus txog 400℃. Engineering rau thermal extremes yuav tsum tau hloov ntawm tus qauv metallurgy mus rau kev tshawb fawb alloy.
