Inoculants Introduction:Inoculants yog ib hom tuaj yeem txhawb nqa graphitization, txo qhov nyiam ntawm lub qhov ncauj dawb, txhim kho morphology thiab kev faib tawm ntawm graphite, nce tus naj npawb ntawm eutectic pawg, kho cov qauv matrix.
Ferrosilicon particle inoculant (tshwj xeeb inoculant rau casting)
Ferrosilicon hais tias yogferrosilicon tsis muaj tshuaj lomsiv rau steelmaking, steelmaking,casting ib inoculant.
Cov yam ntxwv ntawm ferrosilicon inoculant:
(1) Qhov sib xyaw ntawm ferrosilicon hais yog sib xws thiab kev sib cais me me;
(2) ferrosilicon particle loj yog ib yam, tsis muaj hmoov zoo, thiab cov nyhuv inoculation yog ruaj khov;
(3) Cov nyhuv inoculation ntawm ferrosilicon hais yog muaj zog dua li cov ferrosilicon zoo tib yam, thiab cov nyiam ua slag kuj me me;
(4) ncua lub neej ntawm pwm thiab txo qhov tsis xws luag;
(5) Txo cov pinhole, txhim kho qhov zoo ntawm cov yeeb nkab cam khwb cia, thiab txhim kho tus nqi ntawm kev xa khoom thawj zaug;
(6) tshem tawm qhov pom tseeb microshrinkage thiab txhim kho kev ua haujlwm ntawm cov hlau castings.
Silica-barium (calcium) inoculant
Silica-barium inoculant, (BA-SI)yog covsiliconhmoov thiab barium hmoov los ntawm kev sib xyaw ua ke raws li qhov kev xav tau, thiab tom qab ntawd los ntawm qhov kub kub ntawm lub cub tawg steelmaking rau hauv cov ntaub ntawv metallurgical ntau. lub qhov ncauj, txhim kho cov morphology thiab kev faib tawm ntawm graphite, nce tus naj npawb ntawm eutectic pawg, thiab kho cov qauv matrix.
Silica-bariuminoculant muaj nuj nqi:
1, ua kom muaj zog graphitization core, refine graphite, txhawb cov grey cam khwb cia hlau kom tau A-hom graphite, txhim kho lub zog, rau cov hlau ductile tuaj yeem ua rau cov graphite hauv cov hlau ductile zoo, puag ncig, txhim kho qib ntawm spheroidization.
2. Nws tuaj yeem txo qhov supercooling degree ntawm cov hlau molten, txhawb cov nag lossis daus ntawm graphite, txo qhov nyiam ntawm lub qhov ncauj dawb, txo cov txheeb ze hardness, thiab txhim kho cov machining kev ua tau zoo ntawm casting.
3. Muaj peev xwm tiv thaiv kev poob qis, lub sijhawm tiv thaiv kev lag luam yog 2 zaug ntawm75 silicon, tus nqi ntawm silicon bariumua tsis taus payog tsawg tshaj li ib nrab ntawm 75 ferrosilicon inoculant, thaum tiv thaiv kev cuam tshuam spheroidification kev lag luam.
4, phab ntsa thickness rhiab heev yog me me, txhim kho cov seem uniformity, txo qhov nyiam ntawm shrinkage thiab looseness.
5, cov tshuaj muaj pes tsawg leeg yog ruaj khov, kev ua granularity yog uniform, muaj pes tsawg leeg thiab zoo sib txawv me me.
6. Melting point yog tsawg (tsawg dua 1300 °), thiab nws yog ib qho yooj yim mus nqus thiab yaj thaum inoculating, thiab scum yog tsawg heev.
