Abstract

The utility model relates to an aluminum discharging groove of an aluminum wheel smelting furnace. A layer of fire-resistant linings is designed in an existing aluminum discharging groove, namely the aluminum discharging groove is composed of an iron outer shell, an asbestine insulating layer, a fire-resistant lining layer and a pouring material layer from outside to inside, when manufacturing is carried out, after the iron outer shell is manufactured, the asbestine insulating layer, the fire-resistant linings and pouring materials are sequentially arranged in a paved mode, finally one-time pouring molding is achieved, the fire-resistant linings are aluminum silicate ceramic fiber silica soaked solutions, and the fire-resistant linings are arranged in the pouring materials and have the advantages of being low in absorbed heat and good in heat preservation effect. It is calculated that in the whole aluminum discharging process, the temperature of molten aluminum can be reduced by 3 DEG C-5 DEG C, and the aluminum discharging groove is suitable for the aluminum alloy wheel smelting process.

Description

Aluminum vehicle wheel smelting furnace goes out aluminium groove

Technical field

The utility model relates to aluminum vehicle wheel melting field, relates in particular to a kind of aluminum vehicle wheel smelting furnace and goes out aluminium groove.

Background technology

Melting is first link that aluminum-alloy wheel is manufactured, this link is rear for casting machine is for stream by solid-state aluminium ingot being dropped into melting furnace fusing, for improving the scaling loss of the thermal efficiency, minimizing aluminium, more technological innovation is carried out in melting and the insulation of always special concern of past people to smelting furnace, and relatively ignores smelting furnace and go out the importance of aluminium groove.This goes out aluminium groove is smelting furnace aluminium flowing-out mouth, going out aluminium groove generally consists of iron shell, heat-insulation layer, castable, because the one deck directly contacting with aluminium liquid is castable, exist recept the caloric large, the poor problem of heat insulating ability, and owing to also needing through links such as transfer refinings to casting for low pressure casting machine holding furnace from going out aluminium, therefore thermal loss is excessive, the cooling of aluminium liquid is too fast not only to energy-conservation unfavorable, and affected the final quality of foundry goods, visible, though it is little to go out aluminium groove, it is also the important step that need to constantly innovate.

Summary of the invention

The purpose of this utility model is to overcome existing aluminum vehicle wheel smelting furnace to go out that aluminium groove heat absorption is fast, thermal loss is large, the poor problem of aluminium liquid heat insulation effect, provide a kind of can better be applicable to casting aluminum wheels go out aluminium groove.

The technical scheme that realizes above object is, a kind of aluminum vehicle wheel calciner goes out aluminium groove, existing, go out to design one deck refractory lining in aluminium groove, this goes out aluminium groove and is respectively from outside to inside iron shell, asbestos heat-insulation layer, refractory lining and pouring material, during making, after iron shell manufacture, additionally arrange successively asbestos heat-insulation layer completing, refractory lining, castable, finally by disposal pouring, be shaped, wherein refractory lining is that alumina-silicate ceramic fibre soaks Ludox, owing to being provided with refractory lining in pouring material, it is little that this material has caloric receptivity, the feature of high insulating effect, through measuring and calculating whole go out in aluminium process, the decline temperature of aluminium liquid can reduce 3-5 ℃, therefore be more suitable for using in aluminum-alloy wheel fusion process.

Accompanying drawing explanation

Fig. 1 is the utility model section of structure.

The specific embodiment

A kind of aluminum vehicle wheel smelting furnace goes out aluminium groove as shown in Figure 1, this goes out aluminium groove and four layer materials, consists of respectively from outside to inside, be iron shell 1, asbestos heat-insulation layer 2, refractory lining 3, castable 4, above material forms by integrated poured after the manufacture that completes iron shell 1, going out aluminium groove with traditional aluminum vehicle wheel smelting furnace compares, the aluminium groove that goes out of this structure has the feature little, high insulating effect of lowering the temperature, and is more suitable for the melting needs of aluminum wheel of vehicle.

Claims

1. an aluminum vehicle wheel smelting furnace goes out aluminium groove, it is characterized in that: this goes out aluminium groove and four layer materials, consists of respectively from outside to inside, be iron shell (1), asbestos heat-insulation layer (2), refractory lining (3), castable (4), above material forms by integrated poured after the manufacture that completes iron shell (1).
