Abstract
The invention relates to a magnesium alloy protective gas melting device. The magnesium alloy protective gas melting device comprises a cover plate and a ventilation device. The cover plate comprises a limiting part and a ventilation part which are connected together in a hinged manner. The ventilation part is provided with the ventilation device, a charging port is formed in the middle of the ventilation part, and a charging cover is arranged on the charging port. The limiting part is provided with a limiting plate, and the limiting plate makes contact with a crucible so that the cover plate can be positioned. The cover plate capable of covering the crucible is arranged, protective gas is introduced into the crucible through the ventilation device, magnesium alloy is melted in the relatively sealed environment, and the protective gas is continuously introduced in the melting process. The requirement for continuous protection is achieved, and contamination of alloy liquid is effectively avoided.
Description
Technical field
The present invention relates to a kind of melting appartus, especially a kind of Mg melting appartus, can be by using
Protective gas realizes the fusion process of magnesium alloy.
Background technology
This invention is from current magnesium alloy fusion process, general at present to be melted using open type, if open type fusing
Do not adopt flame-retarding means, the magnesium alloy melted after magnesium alloy heating fusing that violent oxidation reaction occurs with air contact directly,
Oxidation reaction discharges substantial amounts of heat makes alloy continue burning.To prevent vigorous oxidation and the burning of magnesium alloy, magnesium is reduced
Oxide inclusion defects and raising alloy mass in alloy, traditional handicraft are typically covered the surface of magnesium alloy, are melted using flux
Agent pollutes aluminium alloy in melting and cast operation inevitably enter into alloy.Liquid magnesium can be prevented using protective gas
Alloy and air reaction, and do not introduce other impurity；But, using traditional open type or semiclosed crucible protective gas
Can overflow from crucible, so as to cause protection failure, the generation vigorous oxidation of magnesium alloy and burning.
The content of the invention
It is an object of the invention to provide a kind of Mg melting appartus, can avoid the dirt produced using flux
Dye, and effectively realize the protection in magnesium alloy fusion process.
The present invention concrete technical scheme be, described Mg melting appartus, including cover plate, ventilation dress
Put, crucible can be closed by described cover plate, it is including the limit part and vent portion that are linked together by hinge joint mode, described
Vent portion on be provided with breather, breather one end is connected with protective gas source of the gas, and the other end is passed through and cover plate set
Several ventholes are equipped with, the medium position of vent portion is additionally provided with charge door, feeding cover is provided with charge door；Limiting section
Set up separately and be equipped with limiting plate, described limiting plate is extended and contacted with crucible to crucible direction for limit part realizes determining for cover plate
Position.The upper position at the sprue gate on described crucible is additionally provided with slag trap, and described slag trap is may be installed on crucible.
The gas outlet position of described breather is circumferentially breather, is provided with gas outlet on described breather.Described lid
Extension is additionally provided with plate and hangs structure, described cover plate is arranged on crucible by hinge.Described protective gas is SF6 and C02
Mixed gas or SF6 and N2 mixed gas, the material of described Mg melting appartus is rustless steel.
This device when in use, is first fixed on and mouth of pot by the present invention, and limiting plate is contacted with crucible, and crucible is preheated
Afterwards, furnace charge needed for adding from charge door, and protective gas is passed through by breather, the charge door insertion heat after alloying is clear
Galvanic couple measures aluminium alloy temperature, and when temperature is suitable being put into gas purifier by charge door again carries out alloy purification.Treat that alloy is accurate
Protective gas melting appartus and crucible are hung out into insulation casting ladle for after finishing, shelves slag plate is arranged on crucible, opening lid
Limit part on plate, is poured into a mould.
The present invention is provided by the cover plate that close can crucible grave, and protection is passed through into crucible by breather
Gas, makes magnesium alloy be melted in the environment of opposing seal, and it is lasting in fusion process be passed through protective gas, realize and hold
The requirement of continuation of insurance shield, and effectively prevent the pollution of aluminium alloy.This device is simple to operate, improves fusing site environment and can give birth to
The high-quality foundry goods of output.
Description of the drawings
Fig. 1 is the structural representation of the present invention；

There is breather 3,3 one end of breather is connected with protective gas source of the gas, the other end passes through cover plate and is provided with several outlets
Hole, the medium position of vent portion 1 are additionally provided with charge door 4, and feeding cover 5 is provided with charge door；Limit part 2 arranges limited
Position plate 6, described limiting plate 6 is extended and contacted with the sprue gate of crucible 10 to 10 direction of crucible for limit part 2 realizes cover plate
Positioning.The upper position at the sprue gate on described crucible 10 is additionally provided with slag trap, and described slag trap may be installed
On crucible.The gas outlet position of described breather 3 is circumferentially breather 7, is provided with gas outlet on described breather.
Extension is additionally provided with described cover plate and hangs structure 8, described cover plate is arranged on crucible by hinge 9.Described protective gas
For SF6 and C02 mixed gas or SF6 and N2 mixed gas, the material of described Mg melting appartus is stainless
Steel.
