Description

Pierwszenstwo: 03.08.1970 (P. 142442) Zgloszenie ogloszono: 26.02.1973 Opis patentowy opublikowano: 15.10.1975 80847 KI. 31a\9/06 Twórcywynalazku: Eryk Czajka, Adam Kuciel, Andrzej Tokarz Uprawniony z patentu tymczasowego: Instytut Metalurgii Zelaza im. Stanislawa Staszica, Gliwice (Polska) Piec oporowy do nagrzewania materialów w atmosferze ochronnej z nastepnym szybkim ich oziebianiem " ' ^ Przedmiotem wynalazku jest piec oporowy do nagrzewania materialów, przedmiotów, próbek i wsadu topionego w dowolnej atmosferze ochronnej doprowadzonej do pieca oraz do ich szybkiego oziebiania przy pomocy medium oziebiajacego równiez dostarczanego w odpowiednim momencie do wnetrza komory grzewczej pieca. Znane sa piece oporowe posiadajace element grzejny w ksztalcie rury, którego wnetrze stanowi komore grzewcza pieca.Celem umozliwienia prowadzenia procesów nagrzewania próbek przy równomiernym rozkladzie tempera¬ tury wzdluz osi pieca, oraz szybkiego ich oziebiania przez wprowadzenie do komory grzewczej medium chlodzacego, skonstruowano piec z komora grzewcza wewnatrz elementu nagrzewajacego wykonanego z materia¬ lu odpornego na szybkie zmiany temperatury. Powierzchnia elementu nagrzewajacego ma profil zapewniajacy równomierny rozklad temperatury wzdluz osi elementu nagrzewajacego. Jeden lub oba konce elementu grzewczego zamkniete sa glowicami, przez które do wnetrza komory grzewczej wprowadzany jest w czasie grzania gaz stanowiacy atmosfere ochronna lub medium chlodzace po zakonczeniu procesu nagrzewania.Przykladowe rozwiazanie pieca oporowego weldug wynalazku przedstawiono w przekroju na zalaczonym rysunku. Piec sklada sie z elementu grzwczego 1 zawierajacego komore grzewcza 2, glowic stykowych 3 i glowic wtryskowych 4. Element grzewczy wykonany jest jako tuleja o profilu czesci elipsoidy obrotowej, co zapewnia równomierny rozklad temperatury wzdluz jego osi podluznej. Prad grzewczy o cluzym natezeniu doprowadzony jest do elementu grzewczego przez glowice stykowa 3 chlodzona wewnetrznie woda doprowadzona do komory chlodzacej 5. Przez glowice wtryskowe 4 do komory grzewczej 2 doprowadza sie gaz stanowiacy atmosfere ochronna lub medium chlodzace przez dwa otwory 6 otwory 7 i kanaly 8. Przedmioty nagrzewane umieszczone sa w komorze grzewczej za pomoca uchwytów przechodzacych przez otwory przelotowe 9 w glowicy wtrysko¬ wej. PL PLPriority: August 3, 1970 (P. 142442) Application announced: February 26, 1973 Patent description was published: October 15, 1975 80847 KI. 31a \ 9/06 Inventors: Eryk Czajka, Adam Kuciel, Andrzej Tokarz Authorized by a temporary patent: Instytut Metalurgii Zelaza im. Stanislawa Staszica, Gliwice (Poland) Resistance furnace for heating materials in a protective atmosphere with subsequent rapid cooling "'^ The subject of the invention is a resistance furnace for heating materials, objects, samples and melted charge in any protective atmosphere supplied to the furnace and for their rapid cooling with a cooling medium also supplied at the right moment to the interior of the furnace heating chamber. quickly cooling them down by introducing a cooling medium into the heating chamber, a furnace was constructed with a heating chamber inside a heating element made of a material resistant to rapid temperature changes. The surface of the heating element has a profile that ensures even temperature distribution along the axis of the heating element. One or both ends of the heating element are closed with heads through which gas is introduced into the heating chamber during heating, which constitutes a protective atmosphere or a cooling medium after the heating process is completed. An example of a resistance furnace of the invention is shown in the cross section in the attached drawing. The furnace consists of a heating element 1 containing a heating chamber 2, contact heads 3 and injection heads 4. The heating element is made as a sleeve with a rotational ellipsoid profile, which ensures an even temperature distribution along its longitudinal axis. The heating current with a low intensity is supplied to the heating element through the contact head 3, internally cooled water supplied to the cooling chamber 5. Through the injection heads 4, a protective atmosphere gas or a cooling medium is supplied through two openings 6 holes 7 and channels 8. The objects to be heated are placed in the heating chamber by means of holders passing through the through-holes 9 in the injection head. PL PL
