Claims (8)
1. Fremgangsmåde til afkøling af metalemner, som er blevet underkastet en nitre-ring/nitrocarburering i et saltbad, kendetegnet ved, at: før afslutningen af den nævnte behandling, bliver kølemidlet, i form af en væske, som har en høj volumetrisk ekspansionsevne under fordampning, påfyldt et kammer (1) indrettet til at fjerne oxygenet indeholdt i kammeret, for at tilvejebringe en inaktiv atmosfære, alle de behandlede emner overføres til kammeret (1) med en minimumhastighed på 6m/min, kammeret (1) lukkes, emnerne efterlades i kammeret over en forudbestemt tidslængde for at nå en temperatur, ved hvilken saltet størkner og danner en beskyttelsesbarriere, emnerne fjernes og underkastes derefter en skylleoperation.
2. Fremgangsmåde ifølge krav 1, kendetegnet ved, at kølemidlet er flydende nitrogen.
3. Fremgangsmåde ifølge krav 2, kendetegnet ved, at kammeret fyldes med flydende nitrogen 2 til 3 minutter før afslutningen af nitrerings/nitrocarburerings-behandlingen.
4. Fremgangsmåde ifølge ethvert af kravene 1 til 3, kendetegnet ved, at skylningen udføres med vand ved en temperatur imellem 40 og 50°C, og derefter med vand ved en temperatur på omkring 20°C.
5. Apparatur til køling af metalemner, som er blevet underkastet nitrerings-/nitro-carburerings-behandling i et smeltet saltbad, kendetegnet ved, at det omfatter et kølekammer (1), i hvilket et kølemiddel i væskeform med en høj volumetrisk ekspansionsevne indføres, hvilket kammer er placeret i direkte relation til en nitrerings-/nitro-carbureringsstation, som er integreret med en overføringsvogn til hurtig overføring ved en minimumhastighed på 6 m/min. af alle emner ind i kammeret.
6. Apparatur ifølge krav 5, kendetegnet ved, at kammeret består af en klokke med to vægge (1a), i hvilken flydende nitrogen indføres, hvilke to vægge (1a) har indretninger til diffusion af nitrogenet i det indre af klokken.
7. Apparatur ifølge krav 6, kendetegnet ved, at bunden i klokken indgriber (1) med organer, som er i stand til at give fri adgang til det indre af klokken for overføring af emner, og til at lukke denne adgang under kølefasen.
8. Apparatur ifølge krav 7, kendetegnet ved, at organerne består af døre (3) og (4), som er fastgjort til en del af behandlingsstationen.
