Izizathu kunye nezisombululo zokuqhekeka kwi-castables ngexesha lokubhaka

Izizathu zokuqhekeka kwi-castables ngexesha lokubhaka ziyinkimbinkimbi, ezibandakanya izinga lokushisa, umgangatho wezinto eziphathekayo, iteknoloji yokwakha kunye neminye imiba. Oku kulandelayo luhlalutyo oluthile lwezizathu kunye nezisombululo ezihambelanayo:

1. Izinga lokufudumala likhawuleza kakhulu
Isizathu:

Ngexesha lokubhaka kwe-castables, ukuba izinga lokushisa likhawuleza kakhulu, amanzi angaphakathi aphuma ngokukhawuleza, kwaye uxinzelelo lwe-steam oluveliswayo lukhulu. Xa idlula amandla okuqina okuphosa, iintanda ziya kuvela.

Isisombululo:

Phuhlisa i-curve yokubhaka efanelekileyo kwaye ulawule izinga lokufudumeza ngokwezinto ezifana nohlobo kunye nobukhulu be-castable. Ngokubanzi, inqanaba lokuqala lokufudumeza kufuneka licothe, kukhethwa ukuba lingagqithi kwi-50 ℃/h. Njengoko iqondo lokushisa liphakama, izinga lokufudumeza linokukhawuleziswa ngokufanelekileyo, kodwa kufuneka lilawulwe malunga ne-100 ℃/h - 150 ℃/h. Ngexesha lokubhaka, sebenzisa irekhoda yobushushu ukujonga utshintsho lobushushu ngexesha langempela ukuqinisekisa ukuba izinga lokufudumeza liyahlangabezana neemfuno.

2. Ingxaki yomgangatho wezinto eziphathekayo
Isizathu:

Umlinganiselo ongafanelekanga we-aggregate kwi-powder: Ukuba kukho i-aggregates eninzi kunye ne-powder eyaneleyo, ukusebenza kwe-bonding ye-castable kuya kuncipha, kwaye ukuqhekeka kuya kubonakala lula ngexesha lokubhaka; ngokuchaseneyo, umgubo omningi kakhulu uya kwandisa izinga lokucutheka kwe-castable kwaye ibangele ngokulula iintanda.
Ukusetyenziswa okungafanelekanga kwezongezo: Uhlobo kunye nobungakanani bezongezo zinempembelelo ebalulekileyo ekusebenzeni kwe-castable. Ngokomzekelo, ukusetyenziswa ngokugqithiseleyo kwe-reducers yamanzi kunokubangela ukugqithisa okugqithisileyo kwe-castable, kubangele ulwahlulo ngexesha lenkqubo yokuqinisa, kunye nokuqhekeka kuya kubonakala ngexesha lokubhaka.
Isisombululo: 

Lawula ngokungqongqo umgangatho wezinto ezikrwada, kwaye ulinganise ngokuchanekileyo imathiriyeli ekrwada enje nge-aggregates, umgubo kunye nezongezelelo ngokweemfuno zefomula ezibonelelwa ngumenzi. Zihlole rhoqo kwaye zihluze izinto ezikrwada ukuqinisekisa ukuba ubungakanani bamasuntswana, ukuhlelwa kunye nokwakheka kweekhemikhali kuyahlangabezana neemfuno.

Kwiibhetshi ezintsha zemathiriyeli ekrwada, qale uqhube uvavanyo oluncinci lwesampulu ukuvavanya ukusebenza kwe-castable, efana ne-fluidity, amandla, i-shrinkage, njl., Lungisa ifomyula kunye nedosi eyongezelelweyo ngokweziphumo zovavanyo, kwaye emva koko uzisebenzise kwisikali esikhulu emva kokuba zifanelekile.

3. Iingxaki zenkqubo yokwakha
Izizathu:

Ukudibanisa okungalinganiyo:Ukuba i-castable ayixutywanga ngokulinganayo ngexesha lokuxuba, amanzi kunye nezongezo ezikuyo ziya kuhanjiswa ngokulinganayo, kwaye ukuqhekeka kuya kwenzeka ngexesha lokubhaka ngenxa yokungafani kokusebenza kwiindawo ezahlukeneyo.
Ukungcangcazela okungaxutywanga: Ngexesha lenkqubo yokuthulula, ukungcangcazela okungaxutywanga kuya kubangela iipores kunye ne-voids ngaphakathi kwe-castable, kwaye ezi ndawo zibuthathaka ziyakwazi ukuqhekeka ngexesha lokubhaka.

Ulondolozo olungafanelekanga:Ukuba amanzi aphezu kwe-castable ayigcinwanga ngokupheleleyo emva kokuthululelwa, amanzi aphuma ngokukhawuleza ngokukhawuleza, okuya kubangela ukuchithwa okuphezulu kunye nokuqhekeka.

Isisombululo:

Sebenzisa ukuxuba oomatshini kwaye ulawule ngokungqongqo ixesha lokuxuba. Ngokuqhelekileyo, ixesha lokuxuba lomxube onyanzelekileyo alikho ngaphantsi kwemizuzu engama-3-5 ukuqinisekisa ukuba i-castable ixutywe ngokulinganayo. Ngexesha lenkqubo yokuxuba, yongeza inani elifanelekileyo lamanzi ukwenza i-castable ifikelele kumanzi afanelekileyo.
Xa ungcangcazela, sebenzisa izixhobo ezifanelekileyo zokungcangcazela, ezifana neerodi ezingcangcazelayo, njl. Ixesha lokungcangcazela lifanelekile ukuba kungabikho amaqamza kunye nokucwila kumphezulu we-castable.

Emva kokuhlanjululwa, ukunyanga kufuneka kuqhutywe ngexesha. Ifilimu yePlastiki, i-straw mats emanzi kunye nezinye iindlela zingasetyenziselwa ukugcina umphezulu we-castable efumileyo, kwaye ixesha lokunyanga alikho ngaphantsi kweentsuku ezi-7-10. Kwizinto eziphoswayo ezinomthamo omkhulu okanye izinto ezikhatywayo ezakhiwe kwindawo ezinobushushu obuphezulu, ukunyanga isitshizi kunye namanye amanyathelo nawo anokuthathwa.

4. Ingxaki yendawo yokubhaka
Unobangela:
Ubushushu be-ambient buphantsi kakhulu:Xa ubhaka kwindawo yokushisa okuphantsi, ukuqina kunye nokumisa isantya se-castable sicotha, kwaye kulula ukukhenkcezwa, okubangelwa umonakalo wesakhiwo sangaphakathi, ngaloo ndlela uqhekeza.

Ukungena komoya okungekho mgangathweni:Ngethuba lenkqubo yokubhaka, ukuba i-ventilation ayilulanga, amanzi aphuphuma ngaphakathi kwi-castable ayikwazi ukukhutshwa ngexesha, kwaye aqokelele ngaphakathi ukuze enze uxinzelelo oluphezulu, olubangela ukuqhekeka.

Isisombululo:
Xa ubushushu be-ambient bungaphantsi kwe-5℃, amanyathelo okufudumeza kufuneka athatyathwe, afana nokusebenzisa isifudumezi, umbhobho womphunga, njl. njl. ukutshisa kwangaphambili indawo yokubhaka, ukuze ubushushu be-ambient bunyuke bube ngaphezulu kwe-10℃-15℃ phambi kokubhaka. Ngethuba lenkqubo yokubhaka, ubushushu be-ambient kufuneka bugcinwe buzinzile ukuze kugwenywe ukuguquguquka okukhulu kweqondo lokushisa.

Ukubeka ngokufanelekileyo i-vents ukuqinisekisa ukungena komoya okulungileyo ngexesha lokubhaka. Ngokuhambelana nobukhulu kunye nokuma kwezixhobo zokubhaka, ii-vents ezininzi zingasetwa, kwaye ubungakanani beegesi bungahlengahlengiswa njengoko kufunekayo ukuze kuqinisekiswe ukuba umswakama unokukhutshwa ngokufanelekileyo. Ngelo xesha, kufuneka kuthathelwe ingqalelo ukuphepha ukubeka i-castables ngokuthe ngqo kwi-vents ukuze ugweme ukuqhekeka ngenxa yokomisa umoya wendawo ngokukhawuleza.
