High Strength Tsawg Cement Corundum fireclay Refractory rwb thaiv tsev Castable
Daim ntawv thov: Hauv ob sab phlu ntawm aluminium melting rauv
Integral casting metallurgical furnace technology yog metallurgical furnace masonry method nyob rau hauv uas refractory castables yog siv los cam khwb cia cov ntaub ntawv refractory rau lub cub tawg ntawm ib lub sij hawm.Cov yam ntxwv ntawm cov thev naus laus zis no nyob rau hauv nws cov qauv zoo, tsis muaj cov pob qij txha cib, thiab lub zog tag nrho, yog li lub tshuab hluav taws xob muaj lub neej ua haujlwm ntev.Sim cov thev naus laus zis no ntawm qee lub tshuab hluav taws xob hauv kev lag luam hauv tsev uas tsis yog-ferrous metallurgical.Kev ua haujlwm kub ntawm lub cub tawg yog siab li 1200 ℃, thiab qhov ua haujlwm kub ntawm lub cub tawg yog siab li 1000 ℃.Circular furnace txais lub cub tawg sab saum toj uncovering thiab pub, me me cub tawg yog phau ntawv slag tshem tawm nrog peb lub qhov rooj rauv, thiab lub cub tawg loj yog cov neeg kho tshuab slag tshem tawm haujlwm nrog ob lub qhov rooj rauv.Cov ntaub ntawv raw yog aluminium ingots, seem cam khwb cia, seem profiles thiab cam khwb cia-dov aluminium coils.Txhua lub tshuab hluav taws xob zoo li qub kuj muaj ob lub qhov rooj rauv rau kev ua haujlwm slagging thiab refining.Yav dhau los, lub qhov cub lub cev yog ua los ntawm cov cib refractory, thiab qee qhov chaw tau yooj yim puas, yog li cuam tshuam rau lub neej thiab kev ua haujlwm ntawm lub cub tawg.Nyob rau hauv kev tsim kho ntawm Zhengzhou lub vev xaib, aluminium melting rauv yog ib nrab nchuav nrog refractory castables los txhim kho tag nrho cov kev pab cuam lub neej ntawm lub cub tawg.
