Abstract
The invention relates to a method for cooling blowing lances that, in order to treat liquid metal melts contained in metallurgical vessels, particularly a steel contained in RH vessels and optionally being subjected to a vacuum, and/or in order to heat metal melts (optionally under a vacuum), can be introduced into and withdrawn from the inside of the vessel by means of a lifting device. A blowing lance comprises at least one inner guiding tube, which serves to guide gases, particularly oxygen, and which has a head-end lance mouth for blowing the gas onto the metal melt, and comprises a cooling jacket, which extends over the length of the lance and which serves to lead a cooling medium therethrough. The cooling jacket is provided in the form of a double-walled jacket tube, which has an inner and an outer cooling channel and which is provided with a redirecting tube in the area of the head end. The metallurgical vessel is connected to a vacuum pump in order to lower the pressure. According to the invention, the instantaneously available suction capacity of the pump limits the maximum flow rate of the gas serving as the cooling medium.
