Abstract
The utility model discloses a compound crucible for aluminium liquid, including this somatic part of semicircular, this somatic part is sunken to be formed semicircular and accommodates the chamber and be used for splendid attire aluminium liquid, and accommodate the chamber and be equipped with the inside wall, scribbling on the surface of inside wall is equipped with ceramic coating, and this somatic part surface is equipped with the heat preservation, this somatic part is equipped with upper mouth part branch and bottom and locates the transition part between upper mouth part branch and the bottom, and upper mouth part divides adoption carborundum and aluminium oxide mix and makes, and the transition part adopts carborundum and aluminium oxide and graphite mix to make, and bottom adoption carborundum and graphite are made. The problem of thermal expansion coefficient mismatch in the heating process can be alleviated to the transition part, avoids the crucible fracture. Simultaneously, ceramic coating is established in scribbling on the surface of inside wall, prevents when heating temperature is too high, the phenomenon of carburization appears, has improved the purity and the quality of aluminium liquid, and the setting of heat preservation can prevent also that the heat runs off the energy can be saved.
Description
Technical field
This utility model relates to crucible technique field, particularly relates to a kind of compound crucible for aluminum liquid.
Background technology
At present in the aluminium alloy course of processing, the aluminum liquid of melting often uses crucible store and add
Heat, during intermediate frequency furnace smelting aluminium alloy, general employing graphite crucible contains, and graphite crucible becomes heating
Body, thermal efficiency ratio is higher, the fusing point of aluminum or aluminium alloy more than 600 degree, and graphite more than 500 just
Chemical reaction can occur, thus aluminum liquid or aluminium alloy solution are formed carburizing, pollute aluminum liquid.And when heating,
Crucible middle and lower part temperature can be higher than upper temp, causes crucible in heating process because of thermal coefficient of expansion not
Mate and ftracture.Crucible upper oral part partial volume is oxidizable, causes pot life to shorten.
Therefore, it is necessary to design a kind of compound crucible for aluminum liquid, to solve above-mentioned technical problem.
Utility model content
For problem present in background technology, the purpose of this utility model is to provide a kind of answering for aluminum liquid
Mould assembly crucible, it is to avoid crucible cracking in heating process and carburizing, improve the efficiency of heating surface and aluminum liquid purity with
Quality.
The technical solution of the utility model is achieved in that a kind of compound crucible for aluminum liquid, including
Semicircular body, body depression forms semicircular host cavity and is used for containing aluminum liquid, and host cavity is provided with
Medial wall, the surface of described medial wall is coated with ceramic coating, and body outer surface is provided with heat-insulation layer, institute
State body be provided with part suitable for reading and bottom and be located at the transition portion between part suitable for reading and bottom, suitable for reading
Part uses carborundum and aluminium oxide to be mixed, and transition portion uses carborundum and aluminium oxide and graphite to mix
Conjunction is made, and bottom uses carborundum and graphite to make.
In technique scheme, described ceramic coating is aluminium oxide ceramics.
In technique scheme, described heat-insulation layer is graphite soft felt.
In technique scheme, described heat-insulation layer is the hard felt of graphite.
This utility model is for the compound crucible of aluminum liquid, by the part suitable for reading in crucible body portion and bottom
Transition portion is set between with, the problem of coefficient of thermal expansion mismatch in heating process can be alleviated, it is to avoid keep away
Exempt from crucible cracking.Meanwhile, the surface of host cavity medial wall containing aluminum liquid is coated with ceramic coating, prevents
When heating-up temperature is too high, the phenomenon of carburizing occurs, improve purity and the quality of aluminum liquid, setting of heat-insulation layer
Put and be possible to prevent heat losses, save the energy.
Accompanying drawing explanation
Fig. 1 is this utility model compound crucible structure schematic diagram for aluminum liquid.
Detailed description of the invention
Below in conjunction with the accompanying drawing in this utility model embodiment, to the technical side in this utility model embodiment
Case is clearly and completely described, it is clear that described embodiment is only that this utility model part is implemented
Example rather than whole embodiments.Based on the embodiment in this utility model, those of ordinary skill in the art
The every other embodiment obtained under not making creative work premise, broadly falls into this utility model and protects
The scope protected.
As it is shown in figure 1, a kind of compound crucible for aluminum liquid described in the utility model, including semicircle
Body 1, described body 1 depression formed semicircular host cavity 10 be used for containing aluminum liquid 2.
Host cavity 10 is provided with medial wall 11, and the surface of described medial wall 11 is coated with ceramic coating 12,
Described ceramic coating 12 is aluminium oxide ceramics, and the coating 12 of aluminium oxide ceramics is possible to prevent in heating-up temperature mistake
, there is the phenomenon of carburizing in Gao Shi, improves purity and the quality of aluminum liquid 2.Also can improve making of crucible simultaneously
Use the life-span.
The outer surface of body 1 is provided with heat-insulation layer 3, and in the present embodiment, described heat-insulation layer 3 is that graphite is soft
Felt or the hard felt of graphite.It is possible to prevent when heating, the heat volatilization waste not absorbed in time, prevent heat
Amount runs off, and reaches to save the beneficial effect of the energy.
Described body 1 is provided with part 4 suitable for reading and bottom 5 and is located between part 4 suitable for reading and bottom 5
Transition portion 6, part 4 suitable for reading uses carborundum and aluminium oxide to be mixed, and transition portion 6 uses carbon
SiClx and aluminium oxide and graphite are mixed, and bottom 5 uses carborundum and graphite to make.Transition portion 6
Setting, the problem of coefficient of thermal expansion mismatch in heating process can be alleviated, it is to avoid avoid crucible to ftracture.
The problem being simultaneously also avoided that partial oxidation suitable for reading, improves oxidation resistance.
This utility model is for the compound crucible of aluminum liquid, by part suitable for reading 4 He in crucible body portion 1
Bottom 5 with between transition portion 6 is set, the problem of coefficient of thermal expansion mismatch in heating process can be alleviated,
Crucible is avoided to ftracture.Meanwhile, the surface of host cavity 10 medial wall 11 containing aluminum liquid 2 is coated with
Ceramic coating 12, prevents, when heating-up temperature is too high, the phenomenon of carburizing occur, improves the purity of aluminum liquid 2
And quality, the setting of heat-insulation layer 3 is possible to prevent heat losses, saves the energy.
The foregoing is only preferred embodiment of the present utility model, not in order to limit this utility model,
All within spirit of the present utility model and principle, any modification, equivalent substitution and improvement etc. made, all
