Abstract
For the high stability aluminium alloy melting furnace of cold-chamber die casting machine, belong in die casting machine equipment technical field, including furnace body unit, heat-generating units and control unit：It is characterized in that：The furnace body unit includes furnace wall, reinforcing layer, insulating layer and collet, it is piled up using refractory brick between furnace wall and reinforcing layer, joint filling and fixation are carried out using high temperature resistant cement between every block of refractory brick, it is provided with reinforcing ring in the reinforcing layer, insulating layer is arranged in the inside of reinforcing layer, it is additionally provided with collet in the inside of insulating layer, the collet ring-type is arranged on the side wall of the interior bottom of insulating layer.The present invention makes the stability of liner more preferable using adding collet in furnace interior, and collet is not damaged under the action of high temperature, the case where preventing high temperature that collet is caused to burst, and it is even closer using what is be bonded between insulating layer and liner after collet, it is more preferable so as to cause heat insulation effect.
Description
Technical field：
This patent belongs to die casting machine equipment technical field, and in particular to a kind of to be used for cold chamber die casting for cold-chamber die casting machine
The high stability aluminium alloy melting furnace of machine.
Background technology：
Cold-chamber die casting machine refers to that injection chamber and injection punch head are not dipped in molten metal, and quantitative molten metal is poured onto
In injection chamber, a kind of die casting machine for then carrying out injection stands the perpendicular placement of injection mode of room cold-chamber die casting machine, it is clear that follows
The injection mode of thermal die casting machine needs to melt aluminum metal before die casting machine carries out die casting, associated melting being equipped with
During stove, it often will appear melting furnace and be not sufficiently stable, the short problem of service life, melting furnace is wide in industrial production at present
The general heat energy utilization equipment used.According to Heating style, melting furnace can be divided into Fuel Furnace and electric furnace two major classes type.General electricity
Stove has three parts composition, i.e. heater element, furnace building material and control device, and the furnace building material clay of old-fashioned melting furnace is resistance to
Firebrick, heat have 35%-40% to be lost by furnace wall, and whole poor thermal insulation property, the thermal efficiency are low.
It can be seen that the aluminium alloy melting furnace being equipped in above-mentioned existing die casting machine is in structure and use, it is clear that there are still
There is inconvenient and defect, and needs to be further improved.Therefore this patent discloses a kind of pressing for cold house with insulation construction
The high stability aluminium alloy melting furnace of casting machine.
Invention content：
Technical problem to be solved by the present invention lies in providing, a kind of heat insulation effect is good, and collet is added using in furnace interior
So that the stability of liner is more preferable, add after collet be bonded between insulating layer and liner it is even closer, so as to cause heat preservation
A kind of better high stability aluminium alloy melting furnace for cold-chamber die casting machine of effect.
For the high stability aluminium alloy melting furnace of cold-chamber die casting machine, including furnace body unit, heat-generating units and control unit；
The heat-generating units are identical as common commercially available aluminum alloy melting furnace structure as control unit, wherein the furnace body unit includes stove
Wall, reinforcing layer, insulating layer and collet are piled up between the furnace wall and reinforcing layer using refractory brick, between every block of refractory brick
Joint filling and fixation are carried out using high temperature resistant cement, the reinforcing ring that section is triangle is provided in the reinforcing layer, in reinforcing ring
Between be filled with high temperature resistant cement, be fixed using cement and reinforcing layer enabled to more to stablize, and reinforcing ring energy therein
Enough play the role of reinforcing rib, the insulating layer is arranged in the inside of reinforcing layer, and collet is additionally provided in the inside of insulating layer；
Further technology, the collet ring-type are arranged on the side wall of the interior bottom of insulating layer；
In order to increase the stability of fusing furnace internal-lining, collet is set in the bottom of insulating layer, the collet needs are held
Hold in the palm liner weight, therefore the setting of collet can make to be bonded between liner and insulating layer it is even closer, to play reinforcement
The purpose of heat insulation effect, therefore higher requirement also proposed for the material of collet, and common material cannot meet resistance to height
The demand of mild load-bearing, so this patent also provides resistance to height in a kind of high stability aluminium alloy melting furnace for cold-chamber die casting machine
The production material of warm collet, is counted in parts by weight, including following components, 100-140 parts of coarse aggregate；40-60 parts of cement；Water 10-
15 parts；3-8 parts of additive；5-10 parts of nano-porous materials；10-20 parts of nanofiber.
By using above-mentioned technical proposal, mud is formed as main material, cement and water using coarse aggregate, cement, water
After be wrapped in surface of aggregate, form glued layer.In glued layer, nanofiber enters for nano-porous materials and nanofiber dispersion
Or part enters in nano-porous materials, nanofiber connects to form reticular structure by nano-porous materials, plays raising
The strong effect of high temperature resistant and the effect and fire resistance for increasing intensity.
Further, the nano-porous materials are silica nano-porous materials, one kind in nano-structure porous silicon or more
Kind；
By using above-mentioned technical proposal, it is porous that silica nano-porous materials and nano-structure porous silicon belong to silicon-based nano
Material, silica and silicon fusing point are high, and nano-porous materials is avoided to melt in a fire；
The further setting of the present invention is：The nanofiber is carbon nano-fiber；
It is described to gather materials including coarse aggregate and fine aggregate, wherein the coarse aggregate includes the rubble that grain size is 5-10mm, it is described
Fine aggregate is the river sand that fineness is 3.0-4.0；
Further technology, the collet are globoidal structure, the bottom cambered surface of the arcuate structure of collet and the liner of melting furnace
Curvature matches；
Further technology, the additive are prepared from the following components：5-10 parts of butadiene-styrene rubber, 2-7 parts of polyethylene wax,
3-5 parts of microwax, 8-12 parts of Petropols, 7-11 parts of rosin resin, 6-12 parts of Corvic, 6-10 parts of naphthenic oil；
Above-mentioned additive by microwax, Petropols etc. use so that concrete additive high temperature resistance enhance,
