Abstract
The utility model relates to the improvement of the existing mini vacuum induction furnace, comprising a vacuum induction furnace body and a vacuum sampling room. The mini multi function vacuum induction furnace blows noble gas in a metal bath through a porous plug on the furnace bottom, and the VOD refining technique of secondary refining can be realized; a dust gun and a measuring probe rod are arranged in the vacuum sampling room; the vacuum injection refining and continuous temperature measurement, oxygen setting and sampling can be carried out.
Description
The utility model relates to the improvement of vaccum sensitive stove.
For opening up new smelting special steel, grope new smelting process, usually need to simulate smelting with small-sized vaccum sensitive stove earlier.Along with improving constantly of steel grade quality requirement and updating of smelting process, the smelting process that some are new, as external refining, technology such as airless injection metallurgy occur, and make original small size vacuum induction furnace no longer suitable, need development novel multifunctional vaccum sensitive stove.Existing novel evacuated induction furnace, external advanced person's is the multifunctional vacuum induction furnace that West Germany Lars company produces, and it adopts a turning arm that has a plurality of sampling temperature measuring equipments, and sampling process is wanted multi-pass operation, and the operating time is long, and structure is more loaded down with trivial details.Though sampling, thermometric are arranged under vacuum, decide functions such as oxygen, can not simulate external refining VOD smelting process and airless injection metallurgical technology.
The utility model purpose is by improving the structure of small size vacuum induction furnace, make its function further perfect, can not only be at continuous sampling, thermometric under the vacuum, decide oxygen, and can realize new technologies such as external refining, airless injection metallurgy, and make more compact and reasonable of structure.
This equipment comprises vacuum induction furnace body and vacuum sampling room two parts, porous plug (9) is equipped with in vaccum sensitive stove furnace bottom centre, can be blown into inert gas to metal bath by furnace shell bottom sealing device, the vacuum pipe (14) of body of heater one side enters vacuum system with furnace gas by dust pelletizing system (13), oxygen rifle (10) tilts to insert in the interior molten bath of vacuum induction furnace body, vacuum sampling room (4) on the bell links to each other with the vacuum chamber (7) of body of heater by a vacuum valve (5), and it has a forepump (15), vent valve (3).Thermometric thief rod (1), oxygen-blowing gun formula podwer gun devices such as (2) are installed by dynamic sealing device along the vertical direction of sampling room.
Further specify implementation procedure of the present utility model in conjunction with the accompanying drawings.
Start forepump when smelting beginning, when making the vacuum sampling room suitable, open vacuum valve and fall podwer gun, can under vacuum, dust, realize the metallurgical new technology of airless injection to the molten bath with molten bath vacuum degree.Oxygen rifle by furnace roof portion is blown into inert gas to the molten bath simultaneously to bath lancing and the porous plug of opening furnace bottom, can realize simulating external refining VOD smelting process.
Take a sample in the smelting process, thermometric, when deciding oxygen, at first close vacuum valve, open the vacuum sampling window, thermometric is installed on demand, is decided oxygen or sampling probe, multi-functional probe also can be installed carry out thermometric simultaneously, decide oxygen, decide the carbon sampling.Close sampling window after the mensuration probe is good and sound, start forepump, when the sampling room is suitable with molten bath vacuum degree, can opens vacuum valve and fall thief rod mensuration bath temperature, oxygen amount or sampling, mensuration finishes and mentions thief rod, close vacuum valve, open vent valve the sampling room is communicated with atmosphere, open sampling window then, take off probe, sample wherein can be analyzed, and can change new probe simultaneously again and repeat aforesaid operations, continues sampling and measuring.Measuring probe and podwer gun can be used alternatingly.
(11) are the body of heater vent valves in the accompanying drawing, and (12) are vacuum gauges, and (8) are induction coils.
The utility model provides a kind of new device of multiple functional, easy and simple to handle, compact conformation for the raising of the exploitation of new steel grade, Study on Smelting Process, steel quality by adopting the new technology such as simulation external refining, jet metaurgy, airless injection metallurgy.
Claims (2)
1, a kind of small size vacuum induction furnace that is used to smelt, it comprises that the body of heater and the sampling thermometric feeler lever that have the metal smelt molten bath is characterized in that:
A) porous plug is equipped with in the bottom of furnace body center,
