Description
Technical field
The induction type furnace apparatus for seamless steel tube production is the utility model is related to, is referred in particular to a kind of for sensing
Anti- escape interior lining panel inside formula heating furnace magnet coil.
Background technology
Induction type heating furnace is by high intensity, powerful electromagnetic induction principle, realizes the work(to round steel blank heating
Can, general heating-up temperature has the characteristics that firing rate is fast, stability is good, pollution-free more than 1000 DEG C, domestic at present
Round steel blank heating institute is widely used before being used for producing tubes by squeezing outside, is one of key equipment of seamless steel pipe hot extrusion producing line, main
Undertake the work(that the round steel pipe after being heated to the round steel pipe before extruding or being preheated to annular furnace carries out reheating
Energy.A complete set of equipment is made up of two 14, region induction type heating furnaces, can to cold burden (room temperature state) and preheating after hot material,
Heating operation is carried out, to the technical requirements of temperature etc. during meeting seamless steel pipe hot extrusion tubulation.
Induction furnace uses vertical structure, there is heating arrangements (electromagnetic induction coil), feeding-discharging mechanism (hydraulic machinery
Hand), signal detection mechanism, conveying mechanism, the composition such as electric control system, wherein electromagnetic induction coil uses vertical structure, by
The parts such as coil body, refractory material, electrical equipment, cooling device, positioner, support meanss form, the blank after preheating
By the portable liter of hydraulic machinery positioned at magnet coil bottom or two actions of decline, realize into and out of electromagnetic induction line
The function of circle.Electromagnetic induction coil is the core component of induction type heating furnace, and high-power electric current produces high magnetic heat release by coil,
The heating function that is rapidly heated to blank round steel, therefore the stable operation of effective guarantee electromagnetic induction coil are realized, just
It is the important measure in induction type heating furnace production run.
Round steel blank frequently passes in and out electromagnetic heating coil, and specification (diameter), material source (cold burden or preheating during due to production
Material), the difference such as steel grade material, therefore one group of interior lining panel (four) is provided with electromagnetic induction coil endoporus circumferential surface, and
Changed in time according to production specification, purpose is exactly electromagnetic induction coil is completely cut off with round steel blank, (is not lodged, is touched by its injury
Wipe, hit etc.).Because interior lining panel can be deformed by blank heating expansion effects, it is therefore desirable to be fixed on the positioning, at present in
The fixed form of liner plate is：Upper edge, which is fixed by guide rod and leaves telescopic leeway, (eliminates the axial deformation position after thermal expansion
Move), lower edge is fixed by lining ring inclined-plane.Such a liner board fixing structure is compact, and dismounting is more convenient (to remove lining ring to compress
Screw can be taken off), it disclosure satisfy that in heating operation, protect the refractory material in electromagnetic induction coil to be not easy by hydraulic jack top
Injury when rising blank caused by grazing, shock, inclination, it is ensured that the normal use of electromagnetic induction coil.
In production practices, there is problems with discovery：When electromagnetic induction coil heats round steel blank, hydraulic jack will
Hot blank jacking after preheating enters in electromagnetic heating coil, and hot blank needs upper and lower motion, hot blank outer surface it is sticky
Shape glass dust tends to stick to the interior lining panel of electromagnetic induction coil, causes interior lining panel to be attached to, adhesion, and with hot blank up and down
Move and be subjected to displacement, finally cause the generation of interior lining panel deformation damage failure, can cause when serious because interior lining panel crimps to fold
The equipment faults such as the refractory material of whole electromagnetic induction coil comes off, electrical equipment damage.After preventing interior lining panel because of adhesion
Displacement deformation, disposed using in interior lining panel end face outside and lining ring gland position spot welding fixed form, but in electromagnetic induction line
Enclose under the condition of high temperature that fixed effect is bad, solder joint is easy to fall off, fails to be inherently eliminated interior lining panel escape, displacement, asking of deforming
Topic, therefore interior lining panel replacement operation is frequent, supplies consumption is big, and repeatability maintenance load is larger, adds production cost, causes electricity
The internal injury of magnetic induction coil, electromagnetic induction coil price is higher, is cost of overhaul highest assembly of elements in complete equipment,
And high-temperature area implements live replacement operation, operating environment is severe, and operating personnel is present by boiling hot danger of burning.
It is to sum up shown, due to being acted on by the double factor of glass dust after liner structure and high temperature melting, electromagnetic induction
Coil interior lining panel can not realize effective positioning, easily occur positioning point failure, interior lining panel escape, displacement, deformation the problem of, influence
To the orderly function of equipment.
