3-(4-chlorophenyl)-4-phenyl-4,5-dihydro-1H-pyrazole 2-(chloromethyl)-3-methylpyridinehydrochloride 1-(2-bromo-4-methylphenyl)ethanone 3-chloroisoquinoline-4-carbonitrile 5,8-dichloropyrido[3,2-d]pyridazine 2-bromomalononitrile 2-(4-(bromomethyl)phenyl)benzo[d]thiazole 1-(bromomethyl)-3-methoxy-2-nitrobenzene 6-bromo-1H-[1,2,3]triazolo[4,5-b]pyridine 4-iodo-2-((trimethylsilyloxy)methyl)thiazole 6-iodoimidazo[1,2-a]pyridine-3-carbonitrile 2-(4-chlorophenyl)-2-morpholinoacetonitrile 4-chloro-7H-pyrrolo[2,3-d]pyrimidine 4-chloroisothiazole 5-bromo-6-chloro-1H-indole 7-chloro-3H-imidazo[4,5-b]pyridine ethyl3-(4-formylphenyl)propanoate 2,3-dibromobenzaldehyde 1-(5H-chromeno[2,3-b]pyridin-7-yl)ethanone 5H-chromeno[2,3-b]pyridin-5-one 3-chloroisoquinoline-4-carbaldehyde (E)-2-(3-oxoprop-1-enyl)benzaldehyde methyl4-formyl-3-nitrobenzoate 5,6-dimethoxy-2,2-dimethyl-2,3-dihydro-1H-inden-1-one 1-methylbicyclo[4.1.0]heptan-3-one 3-nitro-4-(trifluoromethoxy)benzaldehyde 2-hydroxyquinoline-6-carbaldehyde 2-nitro-3-(trifluoromethyl)benzaldehyde 1-(2-fluoro-4-methoxyphenyl)propan-2-one tert-butyl3-fluoro-4-oxopiperidine-1-carboxylate tert-butyl3-oxopropylcarbamate 2,2-dimethylcyclohexanone 9H-carbazole-3-carbaldehyde N,N-dimethyl-2-oxoacetamide 2-methylpent-4-yn-2-ol 3-tert-butyl-4-hydroxybenzonitrile 4-bromo-2-tert-butylphenol 1,3-dibutoxypropan-2-ol methyl4-hydroxyquinoline-6-carboxylate methyl3-cyano-4-hydroxybenzoate 4-chloro-6-methoxyquinolin-7-ol 3,4-dihydro-2H-benzo[b][1,4]oxazin-7-ol 2-(2-aminothiazol-5-yl)ethanolhydrochloride (R)-ethyl2-chloropropanoate (S)-4-amino-5-(4,4-dimethylcyclohexylamino)-5-oxopentanoicacid (1s,4s)-4-hydroxycyclohexanecarboxylicacid (S)-2-(tetrahydrofuran-3-yloxy)aceticacid (1S,4R)-1-methyl-4-(prop-1-en-2-yl)cyclohex-2-enol (R)-4-(hydroxymethyl)oxazolidin-2-one (S)-4-(hydroxymethyl)oxazolidin-2-one 化工資訊
日前，國(guó)鑫鋁業(yè)公司熔鑄車間生產(chǎn)技術(shù)人員經(jīng)過(guò)連續(xù)作戰(zhàn)成功試制出8支7075合金Φ472×144mm空心錠，破解了公司生產(chǎn)大規(guī)格硬鋁合金的技術(shù)難題，為生產(chǎn)大規(guī)格硬鋁合金空心錠和重新占領(lǐng)鋁合金無(wú)縫管市場(chǎng)奠定了基礎(chǔ)。
7075合金作為硬合金中的超硬合金，較普通的7系產(chǎn)品，具有合金含量要求高、合金化程度更高等特點(diǎn)，同時(shí)其合金含量控制難度大、鑄造成型難度大，鑄造易產(chǎn)生通裂缺陷，尤其是空心錠鑄造對(duì)工裝設(shè)計(jì)制作及工藝參數(shù)匹配均提出了極高要求，目前國(guó)內(nèi)同行業(yè)中還沒(méi)有多支同水平鑄造的廠家與相關(guān)技術(shù)予以參考和借鑒，為攻克這一技術(shù)難題，公司不惜投入人力、物力，不間斷的進(jìn)行試制，并以6系合金、2系合金生產(chǎn)作為前提，為7系合金的組織生產(chǎn)積累經(jīng)驗(yàn)，在試制過(guò)程中，車間組織技術(shù)人員與工裝設(shè)備廠家進(jìn)行溝通、交流，對(duì)關(guān)鍵部件重新進(jìn)行加工制作，改造后的工裝設(shè)備使操作人員在鑄造作業(yè)時(shí)便于控制、便于操作，為空心錠的鑄造提供了根本保證，從而一舉成功試制出7075合金Φ472×144mm空心錠，鑄造成型率達(dá)100%，鑄錠的表面質(zhì)量、內(nèi)部質(zhì)量均符合工藝要求。
7075大規(guī)格合金空心錠的成功鑄造，極大了提振了員工信心，也為空心錠的批量生產(chǎn)創(chuàng)造了條件，下一步熔鑄車間將繼續(xù)對(duì)Φ260mm、Φ605mm空心錠生產(chǎn)進(jìn)行技改調(diào)試并達(dá)到批量化生產(chǎn)，為公司重新占領(lǐng)國(guó)內(nèi)外的高硬質(zhì)鋁合金大規(guī)格無(wú)縫管的市場(chǎng)做出應(yīng)有得貢獻(xiàn)！
