Copper Components for Metallurgical Processes



Since 1982 Esart foundry has specialized in the casting of copper components with the maximum cast mass of 5 Tons. These components are used where a very high electrical conductivity min. of 85 IACS% is required.

All the components are supplied finish machined. Our company supplies different copper base alloys castings, copper forging and components assembled by welding.




DUMA-BANDZINK galvanizing and aluminising lines


DUMA-BANDZINK galvanizing and aluminising lines are characterised by their outstanding coating results using a minimum of layer metal. Moreover, the equipment is robust in service and easy to maintain and to handle.

Ferroseosuunin laskureiän lähialueen lämmönsiirtoanalyysi



Analyysissa tutkittiin vesikiertoisen kuparijäähdytyselementin toimintaa ja tehon tarvetta. Kuormitustapauksena oli sulan ferroseoksen ja kuonan kaato ulos uunista, jolloin sula massa kuumentaa uunin rakennetta sisäpinnalta sekä kaatoreiän sisältä.

Analyysissa sovellettiin Fourierin lain ratkaisuja elementtimenetelmällä lämmön johtumiselle tasoseinämässä, jossa lämpö siirtyy vain yhdessä suunnassa.

Laskennan tuloksena saatiin laskureiän lähiympäristön stationäärinen lämpötilajakauma, lämpövuo rakenteen sisällä sekä vaadittu jäähdytysteho sekä perustilanteessa että eroosion vaikutuksen jälkeen.
