Ọrụ nke tundish nozzles

A na-eji nozzle Tundish eme ihe na-agbaze nchara na ịwụsa na tundish. Mgbe a na-eji ya, ọ dị mkpa ka ọ na-eguzogide okpomọkụ dị elu ma na-eguzogide ọgwụ corrosion ígwè a wụrụ awụ, ka o wee belata mmebi nke nozzle tundish. Enwere ọtụtụ ụdị na akụrụngwa nke nozzle tundish, na ihe a na-ahụkarị nke nozzle tundish bụ eriri oxidation. Nke a bụ n'ihi na oxidizer nwere ezigbo nguzogide okpomọkụ dị elu na nguzogide corrosion, nke nwere ike igbochi mmetụta nke ígwè gbazere n'ụzọ zuru ezu.

Ọrụ nke nozzle tundish na ihe ndị ọ chọrọ maka ihe mgbagha:

(1) Tundish bụ nnukwu akpa maka ịnata, chekwaa na ikesa mmiri ladle. A na-eji nke nta nke nta mepụta teknụzụ ọgbara ọhụrụ dị ka imezi okpomọkụ, imezi ihe ndị na-eme ka ihe na-eme ka ọ dịkwuo mma.

(2) A na-achọrọ ihe ndị na-atụgharị anya ka ha nwee obere refractoriness, ma ha chọrọ ka ha na-eguzogide corrosion nke nchara nchara na nke a wụrụ awụ, na-enwe ezigbo ujo ujo, nwere obere okpomọkụ conductivity, ezigbo mkpuchi mkpuchi okpomọkụ, enweghị mmetọ iji gbazee. ígwè, ma dị mfe ịtọgbọ na ịkwatu.
