Heat Resistant Cast Steel Pipe yog dab tsi?
Thaum tshav kub kub resistant cam khwb cia steel yeeb nkab yog feem ntau tsim los ntawm centrifugal casting. Cov khoom siv tshwj xeeb - cov hlau tsis muaj cua sov, tuaj yeem ua kom zoo thiab ua haujlwm tsis tu ncua nyob rau hauv qhov kub thiab txias ib puag ncig ntawm 600℃~ 1400 degree.
Thaum tshav kub kub resistant cam khwb cia steel kav ua lub luag hauj lwm tseem ceeb nyob rau hauv boiler, rauv, tshav kub exchangers, chav kab, kilns.
Raws li cov kws tshaj lij centrifugal casting Hoobkas, Shata Machinery tau muab cov kav dej kub resistant cam khwb cia hlau kav tau ntau xyoo, thiab tau xa ntau pua ntawm cov tsis yog- qauv cua sov- cov kav hlau resistant rau cov neeg muas zaub los ntawm teb chaws USA, Canada, European, Australia...
Cov yeeb nkab twg yog Kub Resistant?
Thaum tshav kub kub resistant steel kav yog engineered los ua cua sov resistant. Cov kav dej kub resistant steel tuaj yeem tiv taus 1112℉ (600 degree) ~ 2552℉ (1400 degree) kub.
Dab tsi Kub Kub Resistant Cast Steel Yeeb Nkab tuaj yeem tiv taus?
Nov yog daim ntawv teev qhov kub siab tshaj plaws rau cov kav hlau thiab cov cua sov-cov kav hlau tsis muaj zog:

Nco tseg: Qhov kev pabcuam tiag tiag yuav tsum raug kho raws li qhov chaw ua haujlwm tshwj xeeb (xws li corrosion, siab, thiab thermal cycling) thiab cov lus pom zoo ntawm cov chaw tsim khoom centrifugal casting.
Kev sib raug zoo ntawm cov hlau tsis muaj cua sov, Incoloy Alloy thiab Inconel Alloy
Incoloy Alloy thiab Inconel Alloy yog cov cim lag luam ntawm Special Metals Corporation. Lawv yog ob qho tib si nyob rau hauv cov khoom ntawm tshav kub-resistant steel.
Incoloy Alloy yog Nickel-Iron-Chromium-raws li alloy, nws kuj yog super austenitic stainless hlau. Incoloy alloy muaj qhov zoo siab - kub lub zog, creep tsis kam, oxidation kuj, thiab corrosion kuj nyob rau hauv nruab nrab - kub (600℃~ 1000℃).
Inconel Alloy yog ib hom Nickel -Chromium-raws li superalloy, suav nrog 60% ~ 75% npib tsib xee thiab qis hlau cov ntsiab lus. Inconel Alloy muaj qhov ua tau zoo siab - qhov kub thiab txias, tuaj yeem ua kom lub zog siab, nkag siab thiab oxidation tsis kam nyob rau hauv qhov kub siab heev 1000℃~ 1200 degree, nws muaj corrosion kuj zoo heev.
Dab tsi yog cov yeeb nkab steel thiab cam khwb cia hlau?
Centrifugal Casting yog cov txheej txheem tsim khoom zoo tshaj plaws rau cov kav hlau cam khwb cia thiab cov kav hlau cam khwb cia. Nws yog txheej txheem txheej txheem uas nchuav hlau molten rau hauv siab - nrawm tig pwm, nyob rau hauv centrifugal rog, molten hlau puv pwm, thaum kawg tau cov castings tom qab solidification thiab txias.
Compared with other casting processes, such as sand casting or permanent mold casting, centrifugal castings have better dense structure, higher mechanical properties, lower cost for hollow structure parts (no need core for casting), and higher material utilization rate around 80%~90% (no need casting gate and risers).
Centrifugal casting yog qhov zoo tagnrho rau qhov chaw nrog cov yam ntxwv sib hloov, xws li cov kav dej, cov raj, lub tog raj kheej, lub tog raj kheej, lub tes tsho, bushings, rings, disks, thiab rollers.
