Di-staen dur castings gyda magnetig rhesymau a atebion.

Ar ôl y cwblhau o y cynhyrchu o di-staen dur castings os y magnetig bydd plwm i ei gynnyrch heb gymhwyso, felly yn y proses o prosesu o staen dur castings talu talu sylw i llawer o manylion, i osgoi oeri molding o staeniau dur castings gyda magnetig atebion.

Fel ni i gyd gwybod, y cynhyrchu o di-staen dur castings o austenitig dur dylai nid fod fod yn magnetig, ond rhai o y cynhyrchion gynhyrchwyd yn yn y deunydd, ond ar ôl spectral profi, y deunydd yn yn gymwysedig mae rhif abnormaledd, felly bod llawer o bobl ni all dod dod y problem a ni datrys hyn problem. Ar ôl ymgynghori a llawer o gwybodaeth a cyfathrebu gyda perthnasol technegol personnel, we wedi dod o hyd y rheswm pam y siâp oer dur castings yn oherwydd y mewnol strwythur o austenitig di-staen dur wedi newid yn y broses o oeri prosesu a molding, some austenite wedi newid i martensite, y martensite o y corff canolbwyntio strwythur is magnetic. Felly pam gwneud y austenite strwythur newid i martensite strwythur?

Stainless steel according to the structure can be divided into austenitic stainless steel, martensitic stainless steel, ferritic stainless steel. Among them, austenitic stainless steel is a kind of stainless steel used ******. Austenitic stainless steel is theoretically non-magnetic, but austenitic stainless steel will produce magnetism after cold working. According to some studies at home and abroad, The reason why the austenitic stainless steel castings are magnetic is that when the stainless steel is heated above the austenitic transition temperature during the processing process and maintained for a period of time, the stainless steel will be transformed into austenite, but then the stainless steel castings need to be cooled and formed. In the rapid cooling process, when the austenite is cooled to the martensite transition temperature, the organization begins to transform into martensite. The transformation will not stop until the temperature drops below the transition temperature to form the martensitic structure. In the production of stainless steel castings, the stability of austenitic stainless steel, the amount of processing deformation, and the processing method may affect its transformation into martensitic stainless steel.

Felly, according i y achosion a dylanwadu ffactorau o martensite, mewn gorchymyn i osgoi y cynhyrchu o magnetig di-staen dur castings, mae'n angenrheidiol i dewis dewis austenitig dur gyda uchel cynnwys austenitig elfennau pryd prynu raw . Gall hefyd yn defnyddio i dileu Magnetig a gwaith caledu ffenomenau. * Mae yn an "alloy degaussing asiant" ar y y farchnad hynny can dileu y magnetedd staen dur castings, a gall trawsnewid yr elfen haearn yn di-staen dur castings i mewn austenite, fel i cyflawni y diben o degaussing%, a yn yr yr un amser, ar ôl ychwanegu y aloi degaussing asiant, y cyrydu ymwrthedd a halen chwistrellu prawf o staen dur castings yn yn da.
