Background technology
Manganeseirom is the Mn-Fe-C ternary alloy containing impurity such as a small amount of P, S, Si.Different by carbon content, low carbon ferromanganese, mid-carbon fe-mn, high carbon ferromanganese can be divided into.Medium-low carbon ferromanganese fusing point is about 1300 DEG C, and high carbon ferromanganese fusing point is 1220 ~ 1270 DEG C; Manganeseirom is mainly used in steel-making and makes reductor, alloy addition.When molten steel carries out alloying operation, in order to reduce scaling loss and ensure that molten steel composition is even, alloy fragmentation Control is advisable at 10 ~ 40mm.Therefore bulk manganeseirom needs before dispatching from the factory to carry out fragmentation, and shattering process can produce a large amount of powder, and on market, powder price is far below bulk alloy.
The obvious advantages such as microwave heating is different from traditional heating mode, and by the waste of energy direct heating of microwave in raw material inside, have selectivity heated material, quick heating, heating efficiency is high, reduces temperature of reaction, Reaction time shorten, energy-saving and cost-reducing.
Ferromanganese powder has good temperature-raising characteristic in microwave field, therefore adopts microwave heating remelting ferromanganese powder to have feasibility, the microwave oven do not designed for ferromanganese powder remelting at present.
Summary of the invention
The purpose of this utility model is to provide a kind of ferromanganese powder microwave remelting furnace, it comprises bell 1, mullite crucible 4, furnace shell 6, gudgeon 7, tilting mechanism 8, motor 9, pedestal 10, frame 11, furnace shell 6 is arranged in frame 11, mullite crucible 4 is provided with in furnace shell 6, thermofin 5 is provided with between mullite crucible 4 and furnace shell 6, microwave generator 12 is arranged on furnace shell 6, frame 11 both sides are provided with gudgeon 7, gudgeon 7 is connected with tilting mechanism 8, motor 9 is connected with tilting mechanism 8 and drives tilting furnace, tilting mechanism 8 is fixed on pedestal 10, furnace shell 6 upper end has iron notch 3, bell 1 is arranged in frame 11 by furnace cover lifting device 13.
Described bell 1 has temperature-measuring port 2 and shielding gas to import and export, for thermometric with pass into shielding gas, bell has sealing, heat insulating function simultaneously.
Described mullite crucible 4 inwall scribbles high temperature resistant protective cover, prevents material and sidewall of crucible from reacting.
Described gudgeon 7 is installed on upper rack, and tilting mechanism 8 can make shaft keep stable at arbitrary inclination.
Described frame 11 installs stainless steel plate, prevents microwave leakage from damaging human body, protect intraware simultaneously.
Described thermofin 5 adopts ceramic fiber cotton, ceramic beaverboard or foaming nano ceramics.
Described microwave generator 12 total power is directly proportional to furnace capacity.
This device also comprises Controlling System 14, and furnace cover lifting device 13, tilting mechanism 8, motor 9, microwave generator 12 are connected with Controlling System 14, and control the motion of these assemblies by conventional control methods.
The utility model realizes like this, carry out fettling operation after having tapped a blast furnace, in mullite crucible 4, load quantitative ferromanganese powder, close bell 1, import and export from the shielding gas of bell and pass into inert protective gas, open microwave generator 12, start to heat ferromanganese powder, after ferromanganese powder reaches fusing point, insulation for some time, treat that manganeseirom remelting is complete, after uniform composition, tap a blast furnace from iron notch 3; First open bell 1 by furnace cover lifting device 13, motor 9 drives tilting mechanism 8 to rotate and drives frame 11 to tilt, and furnace shell 6 also and then tilts simultaneously, and molten iron flow into hot metal ladle from iron notch 3, shakes positive frame after having tapped a blast furnace, and carries out lower stove remelting.
Advantage of the present utility model and positively effect: microwave remelting furnace adopts micro-wave energy to be thermal source, and heating efficiency is high, can relatively reduce alloy melting temperature.Pass into shielding gas, the anti-blocking of energy, manganese are oxidized, reduce scaling loss.Alloying constituent after remelting is even, and component content meets trade mark requirement.This equipment volume is little simultaneously, and heat-processed is easy to control, and cost of investment is low.
