Zusammenfassung:	The invention relates to a method for controlling the temperature of components or parts in high temperature metallurgical reactors. The components or parts are equipped with at least one evaporation cooled unit, which evaporation cooled unit contains a cooling medium which is in liquid state at the temperature at which the components or parts is set to operate and which cooling medium has a boiling point within a preset temperature range at which the component is set to operate. The amount and/or the temperature of a second cooling medium used to condense the vapour of the cooling medium in the evaporation cooled unit are regulated and controlled in order to keep the pressure within the evaporation cooled unit and thereby the temperature of the liquid cooling medium in the evaporation cooled unit, within a preselected range. The invention further relates to a method for regulating the operation of high temperature metallurgical reactors containing at least of one component equipped with an evaporation cooled unit, which evaporation cooled unit is set to operate within a preselected temperature range. The heat flow from the evaporation cooled unit and/or the temperature in the liquid cooling medium in the evaporation cooled unit are continuously measured and these values are used as parameters for controlling and regulating the process carried out in the high temperature metallurgical reactor. L'invention concerne un procédé de régulation de la température de composants ou de pièces de réacteurs métallurgiques haute température. Ces composants/pièces sont équipés d'au moins une unité refroidie par évaporation contenant un milieu de refroidissement. Ce milieu de refroidissement est à l'état liquide dans les températures de réglage de fonctionnement des composants/pièces. Le point de distillation de ce milieu de refroidissement se situe dans la plage de réglage du fonctionnement des composants/pièces. On régule la quantité et/ou la température d'un second milieu de refroidissement utilisé pour condenser la vapeur du milieu de refroidissement de l'unité refroidie par évaporation pour maintenir la pression dans l'unité refroidie par évaporation, et de fait la température du milieu de refroidissement liquide de l'unité refroidie par évaporation, dans une plage prédéterminée. Par ailleurs, l'invention concerne un procédé de réglage du fonctionnement des réacteurs métallurgiques haute température comportant au moins un composant équipé d'une unité refroidie par é
