Abstract
The utility model relates to a metal melting device, in particular to a molten metal furnace turning mechanism which mainly solves the technical problems that in the prior art, a melt is fully exposed in the air during the furnace turning process, thus causing the contact area between aluminum liquid and air to be increased and increasing hydrogen content in the aluminum liquid, furthermore, the fall caused by the flowing-down of the aluminum liquid causes the surface of the aluminum liquid to writhe and to easily generate oxidization reaction with oxygen, therefore, the oxidized entrapped slag is increased in the melt. The mechanism comprises a melting furnace (1) capable of being filled with the aluminum liquid and is characterized in that the bottom of the melting furnace (1) is connected with a streaming pore brick (2) with a hole, in which a flow control device is arranged and the outlet of which is provided with a heat preservation pool (3), the wall of the heat preservation pool (3) is provided with a closed flow passage (4), and the other end of the flow passage (4) is arranged at the hole of the streaming pore brick (2).
Description
Technical field
The utility model relates to a kind of apparatus for melting metal, especially relates to a kind of to the isostructural improvement of the molten metal mechanism of falling the stove.
Background technology
The operation that can both run in the melting of aluminium alloy is exactly down stove, and the stove that falls promptly is a process of the metal bath of adjusting composition and temperature being put into insulation pond or holding furnace by smelting furnace.Because what the our factory adopted is horizontal continuous-casting technology, so the flow of aluminium liquid when falling stove aluminium liquid is very little, the stove that falls is chronic.Chinese patent discloses a kind of corundum and has banished stove (Granted publication number: CN2828040Y), it comprises body of heater, suspended electrode in the body of heater, be provided with opening in the side wall of furnace bottom, opening is outside equipped with the baffle plate suitable with opening, be connected with support on the baffle plate, opening is arranged on and the nearest position of described electrode horizontal range.But this stove of banishing is the same with the furnace structure that falls shown in Figure 1, in when falling the stove, aluminium liquid during by chute melt can be exposed in the air fully, and aluminium liquid flows to from smelting furnace and forms about 15 centimetres drop and make aluminium liquid liquid level occur seething when being incubated the pond.Above reason increases aluminium liquid and air contact area, aluminium liquid is easy to absorb airborne aqueous vapor and causes aluminium water hydrogen content to raise, the aluminum melt hydrogen content is about: 0.30～0.40ml/100gAl, and aluminium liquid easy and oxygen generation oxidation reaction when seething make oxide slag inclusion increase in the melt.
The utility model content
The utility model technical issues that need to address provide a kind of molten metal mechanism of falling the stove, it mainly is to solve existing in prior technology when falling stove melt can be exposed to fully in the air, make aluminium liquid and air contact area increase, cause aluminium water hydrogen content to raise, and the drop that aluminium liquid flows down makes aluminium liquid liquid level occur seething, easily and oxygen generation oxidation reaction, make the technical problem of oxide slag inclusion increase in the melt etc.
Above-mentioned technical problem of the present utility model is mainly solved by following technical proposals:
The molten metal of the present utility model mechanism of falling the stove, comprise the smelting furnace that aluminium liquid can be housed, it is characterized in that the bottom of described smelting furnace is connected with the stream eye brick of a perforate, stream eye brick is provided with flow control device in the hole, the exit in stream eye brick hole is provided with the insulation pond, have airtight runner on the pool wall in insulation pond, the other end of runner is located at the tapping of stream eye brick.The sidewall of smelting furnace is provided with furnace lining, and stream eye brick is located at the bottom of furnace lining.The insulation pond is located at the below of smelting furnace one side, like this can be so that melt can rely on himself gravity inflow insulation pond.
As preferably, at the bottom of described runner includes and is communicated with insulation pond, pond respectively, two sections horizontal segments of stream eye brick tapping, and the vertical section that is communicated with two sections horizontal segments.Two sections horizontal segments and vertical section are formed " Z " font, like this can be so that melt comparatively gently flow to the insulation pond from smelting furnace.
As preferably, described flow control device is made up of the cone that the body of rod and body of rod end connect for control stream pricker, control stream pricker.The cone maximum gauge of controlling stream pricker end adapts with the bore dia that flows the eye brick, can control the flow of melt after feasible control stream pricker patchhole is interior.
Therefore, the utlity model has and avoided aluminium liquid to contact, characteristics such as aluminium liquid directly feeds insulation pond bottom, and aluminium liquid liquid level can not produce and seethe, and the hydrogen content of aluminium alloy melt and oxide slag inclusion amount are lower, and be simple and reasonable for structure with the air large tracts of land.
Description of drawings
Accompanying drawing 1 is a kind of structural representation of the former mechanism of falling the stove;
Accompanying drawing 2 is a kind of structural representations of the present utility model.
The specific embodiment
Below by embodiment, and in conjunction with the accompanying drawings, the technical solution of the utility model is described in further detail.
Embodiment: the molten metal mechanism of falling the stove that this is routine, as Fig. 2, aluminium liquid is equipped with in the insulation pond 3 that a smelting furnace 1 is arranged and be located at smelting furnace one side bottom in the smelting furnace.Smelting furnace 1 sidewall bottom is connected with a stream eye brick 2, and stream eye brick 2 has the hole that aluminium liquid is flowed out, and is plugged with the control stream pricker 5 of controlled system aluminium flow quantity in the hole, and control stream pricker 5 is made up of the cone that the body of rod and body of rod end connect.Have airtight runner 4 on the pool wall in insulation pond 3, runner 4 includes two sections horizontal segments, and the vertical section that is communicated with two sections horizontal segments, and wherein one section horizontal segment is communicated with at the bottom of the pond in insulation pond 3, and another section horizontal segment opening is at the tapping of stream eye brick 2.
In when falling the stove, by the flow of control stream pricker 5 control aluminium liquid, aluminium liquid flows out from the tapping of stream eye brick 2, is incubated by runner 4 diameter flows to the bottom that is incubated pond 3 then.Because runner 4 is airtight, has avoided aluminium liquid to contact with the air large tracts of land, makes the hydrogen content of aluminium liquid only be: 0.25-0.30ml/100gAl.
