Yintoni ekufuneka uyinikele ingqalelo xa usebenzisa Ibhokisi yohlobo lokumelana neziko

Ukushisa okuphezulu kwesithando sokumelana nohlobo lwebhokisi kunokufikelela kwi-1800 degrees. Unokucinga ukuba iqondo lobushushu elinjalo liya kubangela iingozi ezininzi zokhuseleko ezisetyenziswayo. Namhlanje, ndiya kwazisa bonke abasebenzisi malunga nezilumkiso zokusetyenziswa kwesitovu. Ngawaphi amanqaku osetyenziso oluthile? Nceda ujonge oku kulandelayo:

1. Isithando somlilo esitsha sohlobo lwebhokisi kufuneka sikhethwe kwaye silungiswe ngaphambi kokuba sihanjiswe ngokulula. Faka intonga ye-thermocouple kwisithando somlilo ukusuka kumngxuma ngasemva kwesithando somlilo, kwaye udibanise i-pyrometer (i-millivoltmeter) ngocingo olukhethekileyo. Qaphela ukuba udibanise izibonda ezilungileyo kunye nezibi ngokungalunganga, ukwenzela ukuba uthintele isalathisi kwi-millivoltmeter ukuba iguqulwe kwaye yonakaliswe.

2. Fumana umbane wombane ofunekayo kwisithando somlilo sebhokisi, okanye udibanise i-transformer i-adjustable connector ukuze wenze umbane wombane uhambelana nombane ofunekayo kwisithando sombane, kwaye udibanise ucingo lomhlaba ukuze ugweme ingozi.

3. Hambisa isibambo se-varistor kwiqondo lokushisa eliphantsi (malunga ne-1/4 isikhundla) emva kwemizuzu eyi-15, emva koko kwindawo ephakathi (malunga ne-1/2 isikhundla), i-15 ukuya kwi-30 imizuzu kamva, kwiqondo lokushisa eliphezulu. Ngale ndlela, ubushushu bunokunyuswa ukuya kwi-1000 ° C ngemizuzu engama-70 ukuya kwengama-90. Ukuba i-1000 ° C ayidingeki, xa iqondo lokushisa liphakama kwiqondo lokushisa elifunekayo, isibambo se-varistor sinokubuyiselwa kwiqondo lokushisa eliphakathi, kwaye ke iqhosha lokulawula ngokuzenzekelayo liyakwazi ukulungiswa kwindawo yokuqhawula ukugcina ukushisa okungapheliyo. Kufuneka kuqatshelwe ukuba xa ukushisa okuphezulu kunyuka, i-rheostat ayikwazi ukulungiswa kwinqanaba eliphezulu ngexesha, kwaye iqondo lokushisa kufuneka linyuswe ngokuthe ngcembe ngezigaba.

4. Emva kokuba into etshiswayo itshisiwe ukuhlangabezana neemfuno, hlisa isitshixo kuqala, kodwa ungavuli ucango lweziko ngoko nangoko, njengoko iziko lomvundla libanda ngequbuliso kwaye laphuka. Lindela de iqondo lobushushu lehle ngaphantsi kwe-200 ° C (okanye nangaphantsi) ngaphambi kokuvula ucango kunye nokusebenzisa i-tong crucible tongs emide ukukhupha isampuli.

5. Musa ukungcangcazela isithando somlilo sohlobo lwebhokisi ngobundlobongela, kuba ucingo lwesithando somlilo luxutywe nge-oxidized emva kokuba lubomvu lushushu, kwaye luba lukhuni kakhulu. Ngexesha elifanayo, musa ukuveza isithando sombane kumswakama ukuze ugweme ukuvuza.

I-6 Ibhodi ye-asbestos ekhuselayo kufuneka ifakwe phantsi kwesiseko ukukhusela umphezulu ukuba ungonakaliswe ngokushisa kunye nokubangela umlilo. Musa ukusebenzisa izitovu zombane ezinobushushu obuphezulu xa kungekho mntu ebusuku.

7. Iibhokisi zokumelana nohlobo lwebhokisi ngaphandle kokulawulwa ngokuzenzekelayo kufuneka zithathelwe ingqalelo ngezikhathi ezithile ukukhusela ukushisa ekuphakameni kakhulu, okunokuthi kutshise ucingo lwesithando somlilo okanye kubangele umlilo.

8. Xa i-furnace yokumelana nohlobo lwebhokisi ingasetyenziswanga, ukutshintshwa kufuneka kutsalwe phantsi ukuze kunqunyulwe amandla, kwaye umnyango wesithando somlilo kufuneka uvalwe ukuze uthintele izinto eziphikisayo ukuba zingatshatyalaliswa ngumswakama.
