Ukuphosa isiphene sentsimbi ethambileyo kunye nendlela yokuthintela

Isiphene esinye: Ayikwazi ukugalela

Iimpawu: i-casting shape ayiphelelanga, imiphetho kunye neekona zijikelezileyo, eziqhelekileyo zibonwa kwiindawo ezincinci zodonga.

Izizathu:

1. I-iron liquid oxygen iyingozi, umxholo wekhabhoni kunye ne-silicon uphantsi, umxholo wesulfure uphezulu;

2. Ubushushu obuphantsi bokugalela, isantya esicothayo sokugalela okanye ukugalela okuphakathi.

Iindlela zokuthintela:

1. Jonga ukuba umthamo womoya mkhulu kakhulu;

2. Yongeza i-relay coke, lungisa ukuphakama kwe-coke ephantsi;

3. Phucula ubushushu bokuphosa kunye nesantya sokuphosa, kwaye musa ukunqumla ukuhamba ngexesha lokuphosa.

Isiphako sesibini: ukushwabana kukhululekile

Iimpawu: umphezulu we-pores unzima kwaye ungalingani, kunye neekristale ze-dendritic, ii-pores ezigxininisiweyo zokunciphisa, ezincinci ezihlakazekileyo ngenxa yokunciphisa, zixhaphake kakhulu kwiindawo ezishushu.

Izizathu:

1. Umxholo wekhabhoni kunye ne-silicon iphantsi kakhulu, i-shrinkage inkulu, ukondla kokunyuka akwanele;

2. Ukushisa okuthululwayo kuphezulu kakhulu kwaye i-shrinkage inkulu;

3, intamo yokunyuka inde kakhulu, icandelo lincinci kakhulu;

I-4, iqondo lobushushu lokuphosa liphantsi kakhulu, ulwelo olubi lwentsimbi engamanzi, luchaphazela ukondla;

Iindlela zokuthintela:

1. Lawula ukubunjwa kweekhemikhali ze-iron liquefaction ukukhusela i-carbon ephantsi kunye nomxholo we-silicon;

2. Lawula ngokungqongqo ubushushu bokugalela;

3, uyilo olufanelekileyo riser, ukuba kuyimfuneko, ngentsimbi ebandayo, ukuqinisekisa ukulandelelana kokuqina;

4. Yandisa umxholo webismuth ngokufanelekileyo.

Isiphene sesithathu: i-crack eshushu, i-crack ebandayo

Iimpawu: Ukuqhekeka okushushu kukuqhekeka ecaleni komda wenkozo kwiqondo lobushushu obuphezulu, kunye nokumila okubuhlungu kunye nombala oxidizing. Ukuqhekeka okushushu kwangaphakathi kuhlala kuhlala kunye nomngxuma wokushwabana.

Ukuqhekeka okubandayo kwenzeka kubushushu obuphantsi, ukwaphuka kwe-transgranular, imilo ecaba, i-metallic luster okanye umphezulu oxidized kancinci.

Izizathu:

I-1, inkqubo yokuqinisa i-shrinkage ivaliwe;

I-2, umxholo wekhabhoni kwisinyithi se-liquid uphantsi kakhulu, umxholo wesulfure uphezulu kakhulu, kwaye ukushisa okuthululwayo kuphezulu kakhulu;

I-3, umxholo wegesi yentsimbi yolwelo mkhulu;

4. Amalungu antsonkothileyo apakishwe kwangoko kakhulu.

Iindlela zokuthintela:

1, phucula uhlobo, undoqo womnyinyiva;

2. Ubuninzi beqhekeza lekhabhoni akufanele libe ngaphantsi kwe-2.3%;

3, lawula umxholo wesulfure;

I-4, i-cupola kwi-oven ngokupheleleyo, umthamo womoya awunakuba mkhulu kakhulu;

5, ukuphepha ukuphosa ubushushu buphezulu kakhulu, kwaye uphucule isantya sokupholisa, ukuze usulungekise iinkozo;

6. Lawula ubushushu bokupakisha.
