Tshaj li core abrasion kuj,Hnav Resistant Alloy Steel Castingskhav theeb superior corrosion kuj piv nrog cov pa roj carbon zoo tib yam thiab grey hlau castings, zoo kawg nkaus haum rau feem ntau muaj kev sib xyaw ua haujlwm kev ua haujlwm nrog kev sib tsoo thiab corrosion. Lawv yog cov khoom lag luam uas nyiam tshaj plaws rau kev lag luam ntsib dual corrosion thiab puas, nrog rau kev tsim tshuaj lom neeg, kev ua cov ntxhia ntub dej, ib puag ncig desulfurization, metallurgical pickling thiab tsim cov khoom siv tshuaj. Feem ntau cov kev lag luam ib puag ncig tsis yog abrasive nkaus xwb. Acid-paj huab cua tshem tawm hauv huab cua, kua qaub- cov ntsiab lus muaj nyob hauv cov khoom siv raw, thiab cov dej tsis muaj zog acidic lossis alkaline txheej txheem dej tsis tu ncua corrode cov cuab yeej castings. Ordinary castings feem ntau ncav cuag qhov kawg ntawm lawv lub neej kev pab cuam ntxov ntxov vim yog xeb, perforation thiab nto tev tawm ua ntej ncav cuag lawv lub neej kev tsim kho.
Ordinary steel castings muaj zog corrosion kuj thiab sai tsim oxidative xeb, pitting corrosion thiab txheej corrosion nyob rau hauv me ntsis acidic / alkaline, av noo, saline thiab corrosive ib puag ncig. Qhov no ua rau cov phab ntsa tas mus li thinning, poob ntawm cov txheej txheem lub zog, thiab thaum kawg tawg, kev puas tsuaj thiab kev ua haujlwm tsis ua haujlwm. Nyob rau hauv lub smelting thiab ntau lawm theem ntawm Wear Resistant Alloy Steel Castings, chromium, npib tsib xee, tooj liab thiab lwm yam anti-corrosion alloy ntsiab yog ntxiv rau hauv cov khoom siv raw. These elements form a dense, stable, firm passivation protective film on casting surfaces, isolating direct contact between acid-base media, water vapor, corrosive dust and the steel matrix. Lawv thaiv kev nkag mus thiab yaig ntawm cov xov xwm corrosive ntawm qhov chaw thiab txhawb cov khoom lag luam tiv thaiv acids, alkalis thiab xeb.
Nyob rau hauv ntau yam me me thiab nruab nrab industrial acid- puag ua hauj lwm tej yam kev mob, nrog rau intermittent kev sib cuag nrog tsis muaj zog acids thiab alkalis, adhesion ntawm acid- puag plua plav, av corrosive huab cua, ntsev pos huab ib puag ncig thiab me ntsis acid-base flushing nyob rau hauv ntub ntxhia ua, cov castings muaj peev xwm ua hauj lwm ruaj khov rau ncua sij hawm, corrosion los yog yuav luag tsis muaj deg. Lawv khaws tag nrho lawv cov kev puas tsuaj qub thiab ua tiav ob qho kev tiv thaiv corrosion thiab abrasion, zoo kawg nkaus yoog mus rau qhov chaw ua haujlwm tsis zoo. Lawv lub neej kev pab cuam nyob rau hauv corrosive ib puag ncig yog ob peb zaug ntev dua li ntawm cov zoo tib yam castings, zoo tshem tawm nquag hloov los ntawm dual poob los ntawm corrosion thiab puas.
Lub caij no, nws yog ib qho tseem ceeb kom paub meej txog cov khoom siv tau. Raws li cov khoom sib xyaw ua ke sib xyaw ua kom puas thiab xeb tsis kam, Hnav Resistant Alloy Steel Castings tsis yog kev tshaj lij ultra- tiv thaiv- cov khoom siv hlau tsis zoo thiab tsis tuaj yeem hloov mus rau qhov hnyav hnyav hnyav. Ntev - lub sij hawm immersion nyob rau hauv siab -concentration muaj zog acid thiab alkali daws, los yog tas li flushing los ntawm siab - siv acids thiab alkalis, yuav sai sai ua kom cov nto tiv thaiv zaj duab xis thiab ceev corrosion thiab abrasion ntawm matrix, yog li tsis pom zoo siv. Hauv cov ntsiab lus, Wear Resistant Alloy Steel Castings ua tau zoo nyob hauv ntau dua 90% ntawm kev lag luam me me thiab nruab nrab acid- puag ncig cov xwm txheej, uas muaj cov nqi siab thiab muaj zog yoog raws. Lawv them nyiaj rau qhov zoo tib yam castings 'tsis muaj zog ntawm cov tsis zoo corrosion kuj thiab ntshiab anti{11}}corrosion castings 'tsis txaus abrasion tsis kam, haum rau feem ntau complex industrial ua hauj lwm tej yam kev mob nrog deb zoo practicality thiab stability tshaj li cov pa zoo tib yam casting khoom.
