Increasingly strict regulations, as well an increased public awareness, are forcing industry, including the foundry to develop new binders for molding sands, which, while being more environmentally friendly, would simultaneously ensure a high quality of castings. Until recently, based on synthetic resins were considered be such binders. However, accurate investigations indicated that sands subjected temperatures liquid metal generated several harmful, even dangerous substances (carcinogenic...
Abstract Suitability of the given binding agent for moulding sands preparation depends on one hand estimation technological properties sand and mould made it obtained casting quality other assessment this influence natural working environment. Out used in foundry industry, with organic binders deserve a special attention. These are based synthetic resins, which ensure obtaining proper sound castings, however, they negatively If initial state these resins not very dangerous people...
Abstract Organic binders applied in foundry plants based on synthetic resins, from the one side influence obtaining required technological properties by moulding sand and - consequence good quality castings, other are source of volatile organic compounds (VOC). Together with resins their hardeners, which although added very small amounts emit during thermal decomposition substances negatively influencing natural environment, also used. Both, hardeners only at high temperatures accompanying...
Abstract Out of moulding sands used in the foundry industry, with organic binders deserve a special attention. These are based on synthetic resins, which ensure obtaining proper technological properties and sound castings, however, they negatively influence environment. resins their initial state these not very dangerous for people environment, thus under an high temperatures generate harmful products, being result thermal decomposition. Depending kind applied resin, temperature such...
The assessment of the harmfulness moulding and core sands is mainly based on investigations compositions gases emitted by liquid casting alloys during mould pouring. results obtained under industrial conditions are presented in this paper. A unique research stand was designed built for aim. It allowed us to determine emissions at individual stages a mass up 50 kg. This approach enables simulation foundry conditions. Moulding bound organic binders (phenol-formaldehyde; furan), inorganic green...
Abstract The assessment of harmfulness two resins applied as a partial substitute coal dust in moulding sands with bentonite - was performed the paper. emission value compounds from PAH and BTEX groups assumed main criterion. Also mixtures Kormix type prepared additions these were tested. Experiments carried out an argon atmosphere temperature range: 500-1300°. obtained values substances recalculated for 1% lustrous carbon content each carrier. It calculations, that NW 1 2 carriers contain...
The publication presents two innovative solutions of drive systems recently developed at the Łukasiewicz – Upper Silesian Institute Technology, Center Electric Drives and Machines. first one is an integrated unit with a power 21 kW, dedicated to floating vessels, in particular houseboats. characterized by compact design high energy efficiency. second solution LEMoK 300 motor maximum 90 small aircraft. only weighs 18 kg has very density, which allowed its direct use prototype hybrid Both were...
The article discusses tests aimed to develop a method enabling the preparation of iron ore sinters applying microwave-assisted mineralisation and subsequently used in ICP-OES technique-based chemical composition analysis. involved use various mineralising mixtures, one which was selected prepare specimens repeatability investigated through repeated same sinter specimen performed under conditions. test results revealed that technique could be routinely analytics. using above-named less...
The introduction of ferrous waste into a technological process requires knowledge the quantitative fraction iron at various oxidation levels. research work discussed in article aimed to develop an effective strategy for handling test material order obtain information concerning speciation, relevant assessing reuse potential waste. determination forms metallurgical involved use titration methods and ICP-OES technique. content ranged from few more than 90 %, whereas proportions individual...
For research purposes and to demonstrate the differences between materials obtained from carbonaceous additives classic green moulding sands, five lustrous carbon carriers available on market were selected.The following tested: two coal dusts (CD1 CD2), hydrocarbon resins (HR1 HR2) amorphous graphite (AG1).The studies of products material effects resulting high-temperature pyrolysis focused determining tendency gas evolution, including harmful compounds BTEX group (benzene, toluene,...
