Kajeno, ke tla u isa Donghuan Malleable Iron Casting Co., Ltd. Ha re ithute ka mokhoa oa ho lahla lehlabathe le koahetsoeng.
I. Tsebo le kutloisiso ea lehlabathe le koahetsoeng
1. Likarolo tsa lehlabathe le koahetsoeng
E na le ts'ebetso e nepahetseng ea matla; metsi a matle, liforomo tsa lehlabathe tse lokiselitsoeng le li-cores tsa lehlabathe li na le li-contours tse hlakileng le meaho e teteaneng, e ka hlahisang likhoele tse rarahaneng tsa lehlabathe; liforomo tsa lehlabathe (li-cores) li na le boleng bo botle ba holim'a metsi, 'me boima bo ka holimo bo ka fihla Ra = 6.3～12.5μm, Ho nepahala ha dimensional ho ka fihla boemong ba CT7～CT9; collapsibility e ntle, 'me ho lahla ho bonolo ho hloekisa.
2. Sebaka sa kopo
Lehlabathe le koahetsoeng le ka sebelisoa ho etsa hlobo le li-cores tsa lehlabathe. Li-mold kapa li-cores tsa lehlabathe le koahetsoeng li ka sebelisoa hammoho kapa ka mefuta e meng ea lehlabathe (li-cores); e ke ke ea sebelisoa feela bakeng sa ho lahla matla a khoheli a tšepe kapa ho theola khatello e tlase, empa hape e ka sebelisoa bakeng sa ho lahla tšepe e koahetsoeng ka lehlabathe le mocheso oa centrifugal; e ka sebelisoa eseng feela bakeng sa tlhahiso ea tšepe e entsoeng ka tšepe le li-non-ferrous alloy castings, empa hape le bakeng sa tlhahiso ea li-castings tsa tšepe.
II. Tokiso ea lehlabathe le koahetsoeng
1. Sebopeho sa lehlabathe le koahetsoeng
Ka kakaretso e entsoe ka lisebelisoa tsa refractory, li-binders, lisebelisoa tse phekolang, litlolo le li-additives tse khethehileng.
2. Ts'ebetso ea tlhahiso ea lehlabathe le koahetsoeng
Mokhoa oa ho lokisa lehlabathe le koahetsoeng haholo-holo o kenyelletsa ho roala ho batang, ho roala ka mofuthu, le ho roala ka mocheso. Hona joale, hoo e batlang e le tlhahiso eohle ea lehlabathe le koahetsoeng e amohela mokhoa oa ho roala o chesang.
3. Mefuta e ka sehloohong ea lihlahisoa tsa lehlabathe le koahetsoeng
(1) Lehlabathe le tloaelehileng le koahetsoeng ke lehlabathe la setso le koahetsoeng
(2) Lehlabathe le koahetsoeng ka mofuta o matla haholo le oa khase e tlaase
Likarolo: matla a phahameng, katoloso e tlase, khase e tlase, khase e liehang, anti-oxidation
(3) Ho hanyetsa mocheso o phahameng (mofuta) lehlabathe le koahetsoeng (mofuta oa ND)
Likarolo: ho hanyetsa mocheso o phahameng, matla a phahameng, katoloso e tlase, khase e tlase, khase e liehang, ho oela habonolo, anti-oxidation
(4) Lehlabathe le koahetsoeng ha bonolo
E na le matla a matle le ts'ebetso e ntle ea ho putlama ha mocheso o tlase, e loketseng tlhahiso ea li-castings tsa tšepe tse se nang ferrous.
(5) Litlhoko tse ling tse khethehileng tse koahetsoeng lehlabathe.
III. Mokhoa o ka sehloohong oa ho etsa mantlha ka lehlabathe le koahetsoeng
Mocheso oa mocheso ke 200-300 ℃, nako ea ho folisa ke 30-150s, 'me khatello ea ho thunya lehlabathe ke 0.15-0.60MPa. Bakeng sa li-cores tsa lehlabathe tse nang le libopeho tse bonolo le lehlabathe le koahetsoeng le nang le mokelikeli o motle, khatello e tlaase ea ho thunya e ka khethoa. Bakeng sa li-cores tsa lehlabathe tse tšesaane, mocheso o tlase oa mocheso o ka khethoa. Ha mocheso oa mocheso o le tlase, nako ea ho folisa e ka atolosoa ka nepo. Resin e sebelisoang lehlabatheng le koahetsoeng ke resin ea phenolic. Melemo ea ts'ebetso ea ho etsa mantlha: ts'ebetso e nepahetseng ea matla; fluidity e ntle; boleng bo botle ba holim'a mokokotlo oa lehlabathe (Ra = 6.3-12.5μm); ho hanyetsa mongobo o matla oa motsoako oa lehlabathe; ho putlama hantle le ho hloekisa habonolo ha li-castings.
1. Mold (mofuta) mocheso
Thempereichara ea hlobo ke e 'ngoe ea lintlha tse ka sehloohong tse amang botenya le matla a lera la khetla, ka kakaretso li laoloa ho 220～260℃
2. Khatello ea ho thunya lehlabathe le nako
Nako ea ho thunya lehlabathe ka kakaretso e laoloa ho 3～10s. Haeba nako e le khutšoanyane haholo, hlobo ea lehlabathe (konokono) e ke ke ea etsoa. Khatello ea ho thunya lehlabathe ka kakaretso e ka ba 0.6MPa; ha khatello e le tlase haholo, ho bonolo ho baka ho thunya ho sa lekaneng kapa ho hlepha. Nako ea ho thatafatsa: Bolelele ba nako ea ho thatafatsa bo ipapisitse le botenya ba hlobo ea lehlabathe (konokono) le mocheso oa hlobo, hangata ho pota 60-120s.
Hajoale, lihlahisoa tsa rona tsa mantlha ke lipeipi tsa tšepe tse bonolo, li-tube clamp, likhokahano tsa foreimi, likhoele tsa moea, li-bolt tse peli, li-clamp tsa bolt, likhoele tsa camlock, likhokahano tse potlakileng, 'mele oa conduit, li-nipples tsa KC, li-hose menders le tse fetang makholo tsa lihlahisoa tseo u ka li khethang. Rea u amohela ho Donghuan Malleable Iron casting bakeng sa lipotso, re tla u sebeletsa ka tieo.
