Isitena esishushu sokujonga isitena

A. Isiphatho sobushushu sesitovu esitshisayo sesitena esitshekisayo. Isitena esitshekishayo esineentunja saziwa njengangoku kwaye samkelwe lushishino lokwenza i-ironmaking. Inamandla okutshintshiselana ngobushushu, indawo yokugcina ubushushu enkulu, umoya opholileyo, kunye nokumelana okuphantsi. Uphawu lokugcina ubushushu obuphethe ubushushu. …

Izitena ezitshekishwayo luhlobo lwezitena ezisetyenziswa ngokufuthi kwisitovu esitshisayo. Umphezulu wayo awulingani, unemingxunya ebonakalayo phakathi. Ngokweempawu zayo zesakhiwo, izitena zokutshekisha ezisetyenziswa kakhulu zisetyenziselwa: imingxunya emi-7, imingxunya eli-19, imingxunya engama-31, imingxunya engama-37, imingxunya engama-65. Ngokwezixhobo ezahlukeneyo ezisetyenzisiweyo, yahlulwe yazitena zokujonga udongwe kunye nezitena eziphezulu zokukhangela izitena.

C. Iimpawu:

Inobuninzi bemingxunya yegridi ebonakalayo ehambelana nomphezulu wecala, kunye nokubekwa kwindawo ebonakalayo kunye nokubekwa kwemijelo kwiindawo ezimbini ezifanayo.

Ukuzinza kwevolumu elungileyo, ukusebenza ngokugqwesileyo kokulayisha umthwalo, uxinizelelo oluphezulu kunye ne-porosity ephantsi. Ukuqhuma kweziko lokutshisa izitovu ezivamileyo zihlala zisebenzisa isitena sokuhlaziya isitena. Izitena zokujonga zigqityiwe zonyusa indawo yokufudumeza, zinciphisa ukusetyenziswa kwezitena ezitshekishayo, kwaye zinciphise kakhulu ukusetyenziswa kwezixhobo ezitsalwayo izitovu eziqhushumbayo, ngaloo ndlela kuncitshiswa utyalomali lwezitovu ezishushu.

D.Isicelo:

Okwangoku, izitena zokujonga zisetyenziselwa ukuqhushumba iziko kunye nezitovu zelangatye. Izitena zokujonga zisetyenziswa ikakhulu kwindawo yokuhlaziya izitovu ezishushu. Izitena zokujonga ezinemingxunya ye-lattice zilungiswe ngocwangco. Iphezulu kunye nezantsi ngemingxunya yezitena zokujonga inokuvumela irhasi ukuba idlule. Ngokweemfuno zobuchwephesha beendawo zobushushu ezahlukeneyo, izitena zokuhlola ezenziwe ngosiliceous, izitena zodongwe, njl njl. Kwezinye izitovu eziqhumayo, izitena eziphezulu zealumina, izitena ze-mullite, izitena zesillimanite, njl.

Umsebenzi wesitovu somoya oshushu kukufudumeza umoya obandayo othunyelwe ngumoya wesithambiso somoya oshushu, kwaye ke umoya oshushu uthunyelwa kwiziko lokudubula ngombhobho womoya oshushu wokuphendula ngokutsha. Isithando sokuqhushumbisa isitovu esishushu sinexesha lokutshisa iziko kunye nexesha lokuhambisa umoya, kwaye amaxesha amabini okusebenza atshintshwa ngamaxesha athile. Ngexesha lokutshiswa ngumlilo, igesi ephuma kubushushu obuphezulu emva kokutsha idlula kwimingxunya yezitena zokujonga isitovu esitshisayo sokutshisa ubushushu kwizitena zokujonga; Ngexesha lokubonelela komoya, umoya obandayo ovela kubethwa ngumoya ungena kwisitovu esitshisayo kwaye uyatshiswa zizitena ezihlola umoya oshushu. Kuthunyelwa kwisithando somlilo ngombhobho womoya oshushu.
