Forming Mechanism And Countermeasure Of Hot - Section Puffing Of Machinery Castings Forming Mechanism and Countermeasure of Hot - section Puffing of Machinery Castings Gray tungsten castings and Machinery Castings hot twist loose forming mechanism: The hot link is thicker than the link wall, so the solidification is slower than the connection wall. When there is no other source, the hot section becomes the source of the coupling wall. For alloys with a solidification temperature range, if the hot section only filters the shrinkage of the joint wall and is not compensated for the shrinkage of the body during the solidification period of the heat section itself, the hot section is formed. To prevent gray iron castings and Machinery Castings hot section of the countermeasures: Usually in the hot section of the release of cold iron, cold iron or suspension casting method to achieve the hot section with its connection wall at the same time solidification (only with the cold iron, the hot section may also be slightly shrinkage). Or with the riser configuration is appropriate, the same use of cold iron, cold iron, and sometimes in the casting (metal) subsidies (also called the meat), to achieve the connection wall hot section of the order of solidification, so as not to become hot joints Of the source, Machinery Castings you can eliminate the hot taper loose.

Formiranje mehanizma i mjere zaštite vruće - odjeljak brodskih strojeva odljevaka Formiranje mehanizma i protumjere vruće - odjeljak puše strojeva odljevaka Siva volfram odljevaka i strojevi za betoniranje vruće uviti slobodi formiranja mehanizma: Topla veza je deblji od zida vezu tako skrućivanja je sporije veze zida. Kad nema drugih izvora, vrući dio postaje izvor spojke zid. Za legure s rasponom temperatura skrućivanja, vrući dio samo filtrira skupljanja zajednički zid i nije kompenzirana za skupljanje tijela tijekom skrućivanja dio topline se, vrući dio je formirana. Kako bi se spriječilo sivog Ljeva i strojevi za betoniranje vrući dio na protumjere: Obično vruće sekciju oslobađanje hladan čelik, hladno željezo ili suspenzija metodom lijevanja postići vruće dio svojih veza zidom u isto vrijeme skrućivanja (samo sa hladno željezo, vrući dio možda malo skupljanja). Ili sa ustaje oblik je prikladno, isto korištenje hladnog željeza, hladno željezo, i ponekad u lijevanje (metalni) subvencije (koji se nazivaju i meso), kako bi se postigla veza zid vrući dio reda skrućivanja, kako ne bi postali vruće zglobova na izvor, strojevi za betoniranje može eliminirati vruće konus labav.
