Abstract
The utility model belongs to the field of metal smelting devices, and relates to a reversible sealed smelting furnace with two integrated furnaces. The furnace is characterized in that a main furnace and a feeding and holding furnace which are combined at an approximately 90-degree angle in an intersecting manner share one furnace mouth and form a sealed furnace body with a furnace lid; and the furnace lid is fixed on a pulley through a furnace lid bearing pumping air pipe, so as to be opened and closed through the sliding movement of the pulley. The furnace can be designed as a vacuum smelting furnace or a non-vacuum smelting furnace (protected by inert gases), and is further characterized in that after the main furnace finishes smelting, smelted liquid metal is poured into the feeding and holding furnace from the main furnace through the overturn of the furnace body, so as to achieve dynamic smelting, improve the degassing effect and more evenly distribute metallic components; and the smelted liquid metal is then filtered by a filtering screen for deslagging, and discharged from the furnace through a bottom casting channel of the feeding and holding furnace once fulfilling the casting conditions after static heat preservation. The utility model with the structural characteristics is applicable to the smelting of pure metals and alloys with high possibility of oxidation, gassing and segregation, and is highly compatible when used with other advanced casting equipment.
Description
[technical field]
The utility model relates to a kind of airtight smelting furnace of twin furnace combination type that can overturn, can be designed to vacuum melting furnace or antivacuum (can take inert gas shielding) smelting furnace based on this, the liquation of its melting material is finished melting at main stove, the upset body of heater, liquation is flowed through, and to pour reinforced holding furnace insulation into static for two stove transition chutes, and remain at before casting in vacuum or the inert gas shielding environment; Its design feature can well be compatible other antivacuum casting equipment.
[technical background]
VIDP vacuum melting furnace of knowing at first altogether and more old-fashioned VIM vacuum melting furnace, their common features are that vacuum melting furnace and vacuum casting equipment are integrated, in the static melting of vacuum state, thereby and at vacuum state directly to punching block casting and cool off naturally and reach the moulding purpose of ingot casting, it is indoor that its casting die group and dynamical system all are incorporated into casting, and structure plays revolver just like feeding of revolver.Because static melting, though be under vacuum environment, but be subjected to the static pressure influence of liquation, its degassing effect is relatively poor, time is longer, simultaneously for guaranteeing vacuum effectiveness, the casting chamber keeps less space as far as possible, this is just to the mould size, total capacity is brought influence, add that non-uniform temperature and cooling velocity are slow in the not intuitive of operation and the casting cycle, so the length of its ingot casting, diameter, structural homogenity, segregation control, feeding control, each side such as impurity content control are unsatisfactory, thereby the hot cold forming processing of later stage material has been brought hidden danger of quality.In order to ensure the quality of products, every ingot casting all will be decaptitated and be truncated simultaneously, because ingot casting length is short, radical is many, has brought big cost and reform through forced labor moving especially.
Next existing most non-vacuum melting stove; its melting, liquation are poured the process of tundish into all less than good inert gas shielding; and the liquation of tundish is to water out from liquation top during casting, so the liquation oxidation is air-breathing very severe, the slagging-off effect is also very bad.
The purpose of this utility model be design a kind of self not with the airtight smelting furnace of turnover twin furnace combination type of casting system; can be designed to vacuum melting furnace or antivacuum (can take inert gas shielding) smelting furnace based on this; thereby liquation can flow between smelting furnace and reinforced holding furnace and reach dynamic vacuum melting or dynamic antivacuum inert gas shielded melting; the degasification slagging-off is effective; chemical composition is uniform and stable; cast temperature is accurate; effectively raise the melting effect; its design feature and other antivacuum casting equipments have favorable compatibility, can better bring into play the strong point of other antivacuum casting equipments.
