Abstract
Spósob tepelnej úpravy ingotov v komorových najma hlbinných peciach s použitím dvoch druhov plynov a různej výhřevnosti podlá vynálezu spočívá v uplatnění viacerých fáz ohřevu reguláciou ich poměru kvality pri znížených nákladoch. Po ukončení fázy ohřevu za konštantného přívodu tepla, sa zaháji fáza vyrovnávania teplotových rozdielov, pri ktorej sa udržuje v peci konštantný objem spalin od 70 do 100 % objem prvej fázy, a to úměrným zvyšováním množstva privádzaného plynu o nižšej výhřevnosti a súčasným znižovaním množstva plynu o vyššej výhřevnosti. Pri úplnom zastavení přívodu plynu o vyššej výhřevnosti sa zaháji dokončovacia fáza, pri ktorej sa postupné znižuje objem spalin a to znižovaním množstva ostávajúceho plynu o nižšej výhřevnosti, až po dosiahnutie obsahu 880 až 900 kj.kg"! ingotu.A way of heat treatment of ingots in the chamber in particular deep-sea kilns using two species gases and the various calorific values of the invention in the application of multiple heating phases by regulation their quality ratio at reduced costs. After terminating the heating phase with constant feed heat, the temperature equalization phase begins differences in which it is kept constant in the furnace flue gas volume from 70 to 100% first phase volume by proportionally increasing the amount of feed gas with lower calorific value and simultaneous reduction the amount of gas with higher calorific value. In full stopping the gas supply with a higher calorific value start the finishing phase, with gradual progress it reduces the amount of flue gas by reducing the amount the remaining gas with lower calorific value up to achieving a content of 880 to 900 kJkg-1 ingot.
Description
Vynález možno využit vo všetkých peciach periodicky pracujúcich, ktoré sú vyhrievané plynmi o rozdielnej výhřevnosti samostatné privádzanými až před horáky.The invention can be used in all furnaces periodically working, which are heated by gases of different calorific value supplied upstream of the burners.
