Abstract
The invention discloses a tool for making a furnace inner part at a center position during construction of a furnace lining material. Three radial cover boards are arranged on the upper end faces of a furnace shell and an internal furnace; an elongated hole is formed in each radial cover board; the upper parts of positioning pin boards are arranged in the elongated holes and the inner sides and the outer sides of the lower parts of the positioning pin boards lean against the internal furnace and the furnace shell respectively; a square hole is formed in the middle of each radial cover board; supporting cover boards are covered on the square holes; a pull rod passes through the supporting cover boards and the square holes respectively so as to directly reach the lower surface of the internal surface; a gasket and a wing nut are sleeved at the upper end of the pull rod; two fixed connecting rods are arranged on the lower part of each positioning pin board; the pull rod is connected with the fixed connecting rods on two sides through supporting levers; and the supporting levers are movably connected with the pull rod and the supporting levers are movably connected with the fixed connecting rods through hinge point pins. On the internal furnace of an induction electric furnace, the tool can control the whole internal furnace so as to make the internal furnace at the center position, and a user can take out the tool conveniently from the upper side. The thicknesses of the surrounding furnace lining, constructed by the tool, of the induction electric furnace are consistent, so that the service life of the induction electric furnace can be prolonged greatly and the use cost of the induction electric furnace can be reduced.
Description
Technical field
Instrument when the present invention is a kind of brickwork lining material particularly makes flue be in the instrument of center during a kind of brickwork lining material.
Background technology
Except furnace cupola, widely used be exactly electric induction furnace to foundary industry when the fusing molten iron.The burner hearth of electric induction furnace is the place of fusing molten iron, and furnace charge becomes molten iron in burner hearth.The geometry of burner hearth has the certain size requirement, and what form burner hearth then is furnace lining material.First in furnace shell, make flue with steel plate, between furnace shell and flue, build again the cupola drop lining material.Make furnace lining material sinter burner hearth into by roast technic, this moment flue because induced-current heating fusing becomes that molten iron need not take out again as a part that melted afterwards molten iron.In building cupola drop lining material process, the position of flue must be in the center in the body of heater.If the position of flue is not in the center in the body of heater, will make lining thickness inhomogeneous.Burner hearth at the thin place of lining thickness can be burnt first.This directly affects the cost of electric furnace life-span and fusing molten iron.Flue being built in the cupola drop lining material process whole, remained the center, then is the key of brickwork lining material quality, and this also is unmanageable problem in the brickwork.
Summary of the invention
Make flue be in the instrument of center when the purpose of this invention is to provide a kind of brickwork lining material, this instrument can on the electric induction furnace flue, just can control whole flue make it be in the center also can be from the top instrument that takes out easily.Lining thickness is consistent around the burner hearth of the electric induction furnace that builds up with this instrument.This can greatly prolong the service life of electric induction furnace and greatly reduce the cost of electric induction furnace fusing molten iron.
Technical scheme of the present invention is: make flue be in the instrument of center during a kind of brickwork lining material.It is the furnace lining space of filling furnace lining material between the furnace shell of electric induction furnace and the flue.Furnace shell and flue upper surface according to furnace shell centered by trisection to being outside equipped with three Radiation cover plates.Every the Radiation patch ends is provided with the strip hole.Below every Radiation patch ends dowel plate is installed all, this dowel plate top is slidingly mounted in the strip hole, and these medial and lateral, dowel plate bottom are respectively near flue outer side edges and furnace shell inner side edge.Be provided with square hole in the middle of every Radiation patch ends.All be stamped the support cover plate on the square hole.Pull bar passes respectively and supports below cover plate and the straight-through flue of square hole, and the length that pull bar passes in the furnace shell is 3/4 to 4/5 of flue height.The pull bar upper end is shape of threads, is set with packing ring and wing nut on the pull rod screw.Two stationary links all are equipped with in each dowel plate bottom.Two stationary links are contained in the pull bar both sides by flue outer side edges and furnace shell inner side edge place but are slightly shorter than pull bar.Be connected by support lever between pull bar and two stationary links, all be flexibly connected by the hinge pin between support lever and the pull bar and between support lever and the stationary links.De Ju From can be by the lift adjustment of pull bar between pull bar and the stationary links.The lifting of pull bar can be regulated by the rotation dish shape nut.
The course of work of the present invention and principle are: electric induction furnace when the brickwork lining material at first with the furnace shell of electric induction furnace in below build the cupola drop lining material to flue bottom level position.Then flue is put into below the furnace shell on the brickwork lining material.Placing the instrument that is in the center to make flue at the brickwork lining material time between furnace shell and the flue again.Make the inside and outside side in dowel plate bottom make flue be in center position in the furnace shell near flue and furnace shell and the position of regulating dowel plate respectively.The rotation wing nut rises pull bar, and pull bar rises two support lever one ends that are connected with pull bar when rising simultaneously.Two support lever one ends make the other end of two support lever that two stationary links are passed laterally when rising.Treat two stationary links respectively with furnace shell and flue tightly mutually by the time wing nut that stops the rotation.The height that when three wing nuts of rotation three pull bars are risen is identical, can make like this flue be in center position in the furnace shell.The cupola drop lining material is built in furnace lining gap between pull bar lower furnace housing and flue.Building the cupola drop lining material when expecting drawbar height, flue just is fixed in the middle of the furnace shell.Take out the support cover plate after counter-rotating wing nut this moment, take out pull bar, stationary links and support lever.Continue again to build the cupola drop lining material to the flue upper end in the furnace lining gap.Also continuing to build the cupola drop lining material expects fire door again to remove at last the instrument that all can make the electric induction furnace flue be in the center when the brickwork lining material.So just finished the work to whole electric induction furnace flue brickwork lining material.
Advantage of the present invention makes flue be in the instrument of center when having provided a kind of brickwork lining material, this instrument can on the electric induction furnace flue, just can control whole flue make it be in the center also can be from the top instrument that takes out easily.Lining thickness is consistent around the burner hearth of the electric induction furnace that builds up with this instrument.This can greatly prolong the service life of electric induction furnace and greatly reduce the cost of electric induction furnace fusing molten iron.
