A Blowing Nozzle for Cupola furnaces, especially Blast Furnace or Cupola furnaces, hot air.

摘要

The nozzle is composed of a hollow body, with an inner shirt and an outer shirt, and the front end connecting them, Through its inner shirt, it emits the hot air of seintroduc E in the furnace of cubilote, and through the gap between its inner shirt and outer shirt, during the operation, a cooling flow, The cracks in the space are divided into a front door and an adjacent main camera, which are hydraulically separatedIt also shows a separate refrigerant circuit with its own connection. Here, the coolant circuit p to the vestibule is composed of two channels, which are parallel to the longitudinal axis of the nozzle, forming the supply and return, and showing a nearly stable transverse part, The front L is connected to an annular channel, which is connected with the lateral position of the channel and circuit of the cooling medium of the main chamber (10), equipped with a cooling channel, which is composed of a spiral and has an almost constant section,The outer shirt (2) is composed of a single basic coat (1), a symmetrical cross-section of a symmetrical transverse and vertical axis, which is directly composed of a solder (4) deformed Conica through the front end (5) and an inner shirt (3), and a channel (11, 13) for supplying and unloading media. Refrigerant in front (5),They are located at 12 points of the desolate nozzle. With respect to the longitudinal axis of the nozzle, they are the main blowing nozzles in the original transverse part (10) of the nozzle, and the welding part (4) forms the lining form (F) of the right flow channel (15) Inhale the main chamber (10).
