Launder for alloy production

Technical Field

The utility model belongs to the alloy melting production facility field specifically relates to a chute is used in alloy production.

Background

During the manufacture of alloy articles, it is often necessary to purify the melt, wherein the purification device is a filter basin. The existing alloy smelting equipment comprises a standing furnace, a filtering basin, a flow plate and a flow groove, wherein the flow groove comprises a first flow groove and a second flow groove, the first flow groove is used for enabling an outlet of the standing furnace to be connected with the filtering basin, the second flow groove is used for enabling the filtering basin to be connected with the flow plate, and during operation, alloy melt in the standing furnace enters the filtering basin through the first flow groove and enters the flow plate through the second flow groove to be cast.

However, the line from the melting furnace to the large flow plate of the alloy melting equipment is long, and the temperature of the molten alloy is lowered more before the molten alloy reaches the flow plate when the alloy melting equipment is used for preparing the soft alloy, so that the temperature of the molten alloy in the flow plate is lower, and the temperature control in the alloy production process is difficult. Patent application No. 201210457606.9 discloses alloy smelting equipment and a launder thereof, and the invention discloses a launder for alloy smelting equipment, which comprises: the first launder is used for communicating the filtering basin with the standing furnace, and the second launder is used for communicating the filtering basin with the flow disc; wherein, the first runner is provided with a first branch; and a second branch communicated with the first flow groove is arranged on the second flow groove. According to the launder provided by the invention, the first branch and the second branch enable the standing furnace to be directly communicated with the flow disc, so that the operation of replacing the launder can be avoided on the basis of saving the flow in the filtering basin and shortening the flow line length of the alloy melt, the time is saved, and the alloy production efficiency is improved. The invention also discloses alloy smelting equipment which is high in production efficiency by applying the launder provided by the invention.

Despite its improvements, the overall apparatus is still relatively complex. The prior alloy production process has the problems that scum in alloy melt cannot be removed, and the scum has great adverse effect on the quality of alloy finished products when the scum is cast along with the alloy melt.

Disclosure of Invention

In order to overcome the not enough among the prior art, the utility model provides an alloy production is with chute, concrete technical scheme is as follows:

the utility model provides a launder for alloy production, its comprises launder main part 1 and baffle 2, launder main part 1 pours into cavity 11 and alloy melt outflow cavity 12 by the alloy melt and constitutes, and the alloy melt outflow cavity 12 bottom is equipped with the outflow hole 121 that runs through, and the alloy melt pours into cavity 11 and alloy melt outflow cavity 12 junction and is equipped with the recess for insert baffle 2.

The height of the gap between the bottom of the baffle 2 and the ground in the launder 1 is 2-5cm.

The inner bottom angle of the launder body 1 is curved, preferably with an arc R5. The design of the arc corners can reduce the stress concentration of the runner structure, prolong the service life of the runner structure in the use environment of cold and hot impact and facilitate the manufacture of the runner (needing demoulding).

The diameter of the outflow hole 121 is 40-60mm.

Preferably, the length of the molten alloy injection chamber 11 does not exceed the length of the molten alloy outflow chamber 12.

The utility model discloses based on pour into the alloy molten liquid into the cavity and the alloy molten liquid flows out the cavity structural as an overall structure, nevertheless be equipped with a baffle in its juncture or combination department, both solved among the prior art alloy molten liquid from pouring into the problem that the ingot casting procedure is long, through the design of baffle, also realized the accuse simultaneously and flowed the function with the drainage. Furthermore, a gap is reserved between the baffle and the bottom plate, so that the characteristic that the scum floats on the surface of the alloy melt is fully utilized, and the function of easily removing the scum is realized. Compared with the prior art, the device overcomes the defects in the prior art, and has the advantages of simple structure and easy operation.
