Technology nke silicon ọla

Usoro nkedo nkesilicon ọla: agbaze na agbaze.A na-agbaze ọla kọpa silicon n'ime ọkụ induction acid.A ga-ebufe ụgwọ ahụ na 150 ~ 200 ℃ tupu etinye ya n'ime ọkụ ahụ, a ga-ehichapụkwa ọla kọpa electrolytic, ṅara n'ọkụ na okpomọkụ dị elu na nke ọma deoiled tupu eji.Ihe mejupụtara Si bụ 3.1%, Mn bụ 1.2%, ndị ọzọ bụ Cu, gbakwunyere Fe bụ 0.25% na Zn bụ 0.3%.Nri nri: mbụ tinye 0,5% flux (boric acid + iko) nke ụgwọ ego, tinye crystalline silicon, manganese metal na electrolytic ọla kọpa, dịkwuo okpomọkụ ka 1250 ℃, tinye ígwè na zinc, ruo mgbe okpomọkụ adahade 1300 ℃, jide. maka 10 min, mgbe ahụ sample ma wụsa n'ime ájá ebu ule ngọngọ.Ọ bụrụ na ngọngọ ule na-ada mbà n'obi n'etiti mgbe ọ jụrụ, ọ pụtara na alloy bụ ihe nkịtị, slag scraping si oven ma kpuchie ya na perlite iji gbochie oxidation na mkpali.

Na-agbapụta okpomọkụ bụ 1090 ~ 1120 ℃.Maka akụkụ buru ibu nwere mgbidi, ọ bụ ihe amamihe dị na ya ịnakwere ntụtụ n'elu ma ọ bụ n'akụkụ ntụtụ gating usoro.Mgbe wụsa okpomọkụ karịa 1150 ℃, na-ekpo ọkụ cracking dị mfe ime, mgbe wụsa okpomọkụ n'okpuru 1090 ℃, undercasting ntụpọ dị mfe ime.

E jiri ya tụnyere tin bronze (Sn 9%, Zn 4%, Cu), nke siri ike nke silicon bronze bụ 55 ℃, ebe nke tin bronze bụ 146 ℃, ya mere mmiri mmiri ya dị elu karịa nke ọla kọpa.Enwere ike ịhụ na ọla kọpa silicon dị elu karịa tin bronze n'otu ọnọdụ okpomọkụ.

Arụ ọrụ ịgbado ọkụ nke ọla kọpa silicon, arụ ọrụ ịgbado ọkụ nke ọla kọpa dị iche iche na-ekewa n'ime akara 4 dị ka uru na ọghọm ha si dị, ọkwa 1 dị oke mma, ọkwa 2 na-eju afọ, ọkwa 3 bụ weldable site na usoro pụrụ iche, ọkwa 4 enweghị afọ ojuju, Tin bronze bụ ọkwa 3, ebe ọla silicon bụ ọkwa 1.

Tụnyere ndị ọzọ ọla kọpa alloys, silicon bronze nwere ala thermal conductivity na ọ dịghị mkpa preheating tupu ịgbado ọkụ, ma ọ nwere thermal brittleness na nso nke 815 ~ 955 ℃.Agbanyeghị, ọ bụrụ na efere nkedo mara mma, ya bụ, efere nkedo ka emechara usoro nkwalite teknụzụ, omume egosila na mgbawa ọkụ agaghị eme na mpaghara okpomọkụ a.

Silicon bronze nwere ike ịbụ ịgbado ọkụ gas, ịgbado ọkụ arc, ịgbado ọkụ TIG akwụkwọ ntuziaka na ịgbado ọkụ MIG.
