Detailed Description
The invention is further illustrated by the following specific figures and examples.
Example 1:
as shown in fig. 1-3, this embodiment provides a novel sprue nozzle for casting high-temperature alloy master alloy, including the sprue nozzle, the sprue nozzle is the hollow structure that both ends link up, the sprue nozzle includes from last first section 1 and the second section 2 that connects gradually extremely down, first section 1 and 2 inner walls of second section link up and form the sprue nozzle passageway 3, all be provided with a plurality of archs 4 on first section 1 and the 2 inner walls of second section.
Wherein: the first section 1 is in the shape of a cone, and the first section 1 is in the shape of a cylinder.
Wherein: the projections 4 are arranged at intervals on both the first section and the second section. The bulge 4 is beneficial to forming stable molten steel, reduces the impact force of the molten steel on the ingot mould and is beneficial to improving the casting quality.
Wherein: the shape of the protrusion 4 is one of a triangle, a circular arc or a square.
Wherein: the material of the pouring nozzle is one of aluminum oxide, magnesium oxide or clay.
Wherein: the first section 1 occupies 2/3 which is the total height of the nozzle.
Wherein: the first section 1 and the second section 2 are integrally formed.
The casting nozzle for casting the high-temperature alloy master alloy can be matched with a tundish for use, and is arranged in the tundish from the lower part of the second section, the first section of the casting nozzle is a cone, the diameter of the upper end of the casting nozzle is large, the diameter of the lower end of the casting nozzle is small, and the casting nozzle is simple to install and easy to replace.
The pouring nozzle can effectively control the pouring speed and the stability of molten steel in the pouring process of the master alloy, and effectively prevent the master alloy from scalding the wall, cold insulating on the surface and cold beans.
The specific implementation mode of the pouring nozzle is as follows:
(1) the pouring nozzle and the tundish are assembled and put into an oven to be dried for standby;
(2) transferring the dried pouring nozzle to a pouring chamber of a vacuum induction furnace during molten steel pouring;
(3) when pouring, the crucible is inclined, the molten steel flows into the pouring nozzle through the tundish, and the flow rate and the stability of the molten steel are controlled by the pouring nozzle to be poured into the ingot mold.
The molten steel flow rate of the casting nozzle is stable and controllable, the impact force on an ingot mold is greatly reduced, and the quality of a master alloy product is obviously improved.
Finally, it should be noted that the above embodiments are only for illustrating the technical solutions of the present invention and not for limiting, and although the present invention has been described in detail with reference to examples, it should be understood by those skilled in the art that modifications or equivalent substitutions may be made on the technical solutions of the present invention without departing from the spirit and scope of the technical solutions of the present invention, which should be covered by the claims of the present invention.
