Abstract
The utility model relates to a magnesium alloy protective gas melting equipment, including apron, air -breather, the apron include the spacing subtotal that links together through the mode of the splicing part of ventilating, ventilate and be provided with the air -breather in the part, the middle part position still is provided with the charge door, being provided with reinforced lid on the charge door, spacing part is provided with the limiting plate, limiting plate and the crucible contact location of realizing the apron. The utility model discloses a be provided with and make crucible soil confined apron to let in protection gas in to the crucible through the air -breather, make the magnesium alloy melt under environment sealed relatively, and last among the melting process let in protective gas, has realized continuous protection's requirement, and has effectively avoided the pollution of alloy liquid.
Description
Technical field
The utility model relates to a kind of melting appartus, especially a kind of Mg melting appartus, can by the melting process using shielding gas to realize magnesium alloy.
Background technology
This utility model derives from current magnesium alloy melting process, the general open type that adopts melts at present, if open type fusing does not adopt flame-retarding means, the magnesium alloy of melting after magnesium alloy heat fused directly contacts with air and violent oxidizing reaction occurs, and oxidizing reaction discharges a large amount of heat makes alloy continue to burn.For preventing vigorous oxidation and the burning of magnesium alloy, reduce the oxide inclusion defects in magnesium alloy and improve alloy mass, traditional technology generally adopts flux to cover the surface of magnesium alloy, and flux inevitably enters into alloy in melting and cast operation and pollutes aluminium alloy.Use shielding gas can stop liquid magnesium alloy and air reaction, and do not introduce other impurity; But, use traditional open type or semiclosed crucible shielding gas can overflow from crucible, thus cause protecting unsuccessfully, the generation vigorous oxidation of magnesium alloy and burning.
Summary of the invention
The purpose of this utility model is to provide a kind of Mg melting appartus, can avoid the pollution using flux to produce, and effectively realize the protection in magnesium alloy melting process.
Concrete technical scheme of the present utility model is, described Mg melting appartus, comprise cover plate, breather, crucible can be closed by described cover plate, comprises the limit part and vent portion that are linked together by hinge joint mode, described vent portion is provided with breather, breather one end is connected with shielding gas source of the gas, the other end passes cover plate and is provided with several production wells, and the medium position of vent portion is also provided with charging opening, and charging opening is provided with feeding cover; Limit part is provided with limiting plate, and described limiting plate is that limit part extends to crucible direction and contacts the location realizing cover plate with crucible.The upper position at the sprue gate on described crucible is also provided with skimming plate, and described skimming plate can be arranged on crucible.The position, air outlet of described breather is circumferentially ventpipe, and described ventpipe has air outlet.Described cover plate is also provided with extension and hangs structure, described cover plate is arranged on crucible by hinge.Described shielding gas is SF6 and C02 mixed gas or SF6 and N2 mixed gas, and the material of described Mg melting appartus is stainless steel.
The utility model in use; first this device is fixed on and mouth of pot; limiting plate contacts with crucible; after crucible preheating; required furnace charge is added from charging opening; and pass into shielding gas by breather, after alloying is clear, charging opening inserts thermocouple measurement aluminium alloy temperature, puts into gas purifier again carry out alloy purification when temperature is suitable by charging opening.After alloy is ready, shielding gas melting appartus and crucible are hung out in insulation casting ladle, shelves slag plate is arranged on crucible, open the limit part on cover plate, pour into a mould.
The utility model is by being provided with the cover plate that crucible grave can be made to close; and in crucible, pass into protection gas by breather; magnesium alloy is melted under the environment of opposing seal; and in melting process continue pass into shielding gas; achieve the requirement of sustainable protection, and effectively prevent the pollution of aluminium alloy.This device is simple to operate, improves fusing site environment and can produce high-quality foundry goods.
