Definitions
- the invention relates to a casting nozzle for thin strip casting systems, in particular for casting thin steel strips
- a nozzle for casting thin steel strips in which the nozzle forms a jerk dam, which is adjacent to a movable support and a front dam, a casting gap between the ruck dam and the front dam being delimited towards the support
- Such nozzles usually consist of refractory material, which is subject to a certain amount of wear at the high temperatures of the molten steel, so that the shape of the casting gap can change during the casting, but in any case the nozzle must be replaced after a certain service life
- the object of the invention was to provide an improved nozzle design in which wear is minimized and in which the melt can be heated in the region of the casting gap
- a secondary inductor is arranged, at least one secondary inductor being water-cooled and projecting into the area of the casting gap
- a secondary inductor consists of several sections which are electrically insulated from one another. As a result, each section acts as a separate secondary inductor
- a plurality of outflow openings for the melt which are adjacent to one another in the direction of the thin bandwidth, are formed between the back and front dams
- a secondary inductor in the Ruckdamm is constructed from a plurality of isolated sections, each with an inlet and outlet for cooling water, the individual sections being dovetailed or arrow-shaped or straight to form the outflow openings of the melt.
- a flow baffle is inside the sections provided that between the inlet and outlet at the end of the sections opposite the casting gap, a forced guidance is achieved up to the head region of the sections facing the casting gap
- electrically insulated sections of a secondary duct with inlet and outlet for cooling water are arranged in the area of the front dam, the sections being dovetailed or arrow-shaped in the head region of the sections, i.e. where the front dam borders the pouring gap, to form outflow openings or are just trained
- a corresponding shape of the front and rear dam should be included, for example circular discharge openings can also be formed.
- the mutually insulated sections in the front dam preferably also have flow baffles between the inlet and outlet inside
- a carrier 1 in particular an endless belt running over rollers, is the one Ruckdamm 2 put on
- the pouring gap 4 is formed between the jerk dam 2 and the front dam 3.
- a secondary inductor 21 borders on the secondary duct 22 Flowing out current flow In section 22, a flow baffle 24 is arranged.
- the secondary inductor 22 is covered by refractory material 25 to the backflow area 5 hm.
- the inductors 22, 23 are water-cooled, they are preferably made of copper
- the front dam 3 is formed by one of a plurality of electrically isolated secondary inductors 32, in which a magnetic inductor 31 induces an electric current.
- the magnetic inductor 31 and secondary inductor 32 are cooled with water, and the magnetic inductor 31 is fed with high frequency Secondary inductor 32 extends beyond the dovetail tip of secondary inductor 22
