Abstract
A pouring nozzle for a device for nozzle insertion and/or removal has a shape that is adapted so as to better resist the stresses imposed by their use and notably the stresses linked to the maintenance of the nozzle in the device. The pouring nozzle is provided with two exposed bearing faces forming with the pouring channel an angle β of 20° to 80°. A pushing device applies thrust force to the nozzle. A casting installation embodies the nozzle and the pushing device.

Pouring nozzle for a nozzle insertion and or removal device, comprising a tubular part defining a pouring channel and, at its upper end, of a plate provided with an orifice defining a pouring channel, said plate comprising an upper surface contacting the upstream element of the pouring channel and a lower surface forming the interface with the upper part of the tubular part of the nozzle;
- said plate comprising two exposed exterior planar bearing surfaces located on opposite sides of the pouring channel and wherein said two bearing surfaces form with the pouring channel axis an angle β of 30° to 60°.
Insertion and removal device for a pouring nozzle having two exposed exterior planar bearing surfaces, comprising a pushing device wherein the resulting thrust force is applied in a direction forming with the pouring channel axis an angle α of 10° to 70° and a guiding device comprising a bearing surface able to receive a pouring nozzle bearing surface, forming with the pouring channel axis an angle β of 30° to 60°.
A nozzle installation system comprising a) a pouring nozzle comprising a tubular part defining a pouring channel and, at its upper end, of a plate provided with an orifice defining a pouring channel, said plate comprising an upper surface contacting the upstream element of the pouring channel and a lower surface forming the interface with the upper part of the tubular part of the nozzle;
- said plate comprising two exposed exterior planar bearing surfaces located on opposite sides of the pouring channel and wherein said two bearing surfaces form with the pouring channel axis an angle β of 30° to 60°;
- and b) an installation device comprising a pushing device wherein the resulting thrust force is applied in a direction forming with the pouring channel axis an angle α of 10° to 70° and a guiding device comprising a bearing surface, able to receive a pouring nozzle bearing surface, forming with the pouring channel axis an angle β of 30° to 60°.
