First embodiment
Below with reference to Fig. 2～5 in detail the first embodiment of the present invention is described in detail.In induction heating equipment shown in Figure 2, intend the direction of heating target plate 1 by solenoid 2 edges of water-cooled steel pipe 7 coileds and flatly extend.The refractory masses 4 that insulated bearing plate 8 is housed is formed at the solenoid 2 inboard heat tunnels 5 that constitute cylindricality.Intending heating target plate 1 is integrally heated by induction heating by heat tunnel 5.
For stainless steel tube 11 being held in mode spiral placement or that reel, as shown in Figure 5, be formed with the bolt that stretches out from water cooling tube 11 by predetermined space.These bolts pass the insulated bearing plate 8 that is placed on the solenoid, are formed by the glass cloth bakelite, and are fixing with stainless steel nut 14.Constituted the left side of cylindricality heat tunnel 5 and these L shaped arc turnings brick 4b of right inwall sidepiece and be connected to, made their outside integrally surround into as shown in Figure 2 for the U-shaped insulated bearing plate.
As shown in Figure 2, on each both sides end face of plain block spare 4a and L shaped arc turning brick 4b, be formed with step 16.Adjacent piece spare 4a and 4b cooperatively interact, and the space between them is combined into integral body by the clay filling as shown in Figure 5.
Induction heating equipment with said structure supplies with the RF electric currents for solenoid 2 when its plan heating target plate 1 by advancing in cylindricality heat tunnel 5, heats whole plate 1 continuously.At this moment, when cooling water being supplied with the heap relative with plan heating target plate and be located at water cooling tube 11 in the refractory masses 4, refractory masses 4 just begins to cool down from its inside.Even refractory masses 4 is heated by the radiant heat that is heated to about 1100 ℃ plan heating target plate 1, also can suppress the temperature that increases very lowly.
These spaces are sealed in the gap of the plain block spare 4a of clay 17 fillings formation refractory masses 4 and the assembling step 16 of L shaped arc comer block part 4b, prevent that radiant heat from passing through therebetween.Because refractory masses 4 has branch's formula structure of being made up of piece spare 4a and 4b, just can absorb thermal stress and prevent cracking by the department of assembly of step 16.Centered on by U-shaped insulated bearing plate 8 through connecting into the outside that makes them owing to constitute heat tunnel 5 these L shaped arc turning bricks right and left inwall side, just can be prevented the corner part cracking.
Fig. 6 shows bright a kind of improved form of the present invention.Stainless steel tube 11 is arranged to spiral form or coiling form.From water cooling tube 11, be extended with bolt 12 according to predetermined space.Bolt 12 passes the insulated bearing plate 8 that is located on the solenoid 2, forms by the glass cloth bakelite, and fixing by stainless steel nut 14.The place that has bolt 12 to stretch out of pipe 11 is wrapped up by glass fibre 18.Pipe 11 entirely remains under this state.
On each both sides end face of the plain block spare 4a that constitutes refractory masses 4 and L shaped arc comer block part 4b, be formed with projection 19 and dimple 20.Projection 19 and the dimple 20 of adjacent block spare 4a and 4b cooperatively interact, and the space between them is linked to be integral body by the clay filling with them.The assembly structure of adjacent block spare 4a and 4b is not limited to above-mentioned form and can is other integrated structure, for example combination of the combination on two inclined-planes or concave-arc part and convex arc section.
As mentioned above, in induction heating equipment of the present invention, the cylindricality refractory masses is to form in conjunction with a collection of plain block spare and arc corner piece.By the cooling water pipe that the water cooling tube of nonmagnetic substance system constitutes, cool off these piece spares internally among being deployed to each piece spare.The high hot temperature that causes for the radiant heat of intending heating plate is pressed very lowly, is prolonged the useful life of refractory masses widely.Prevent the dielectric breakdown or the short circuit of solenoid 2 in the time of can growing with asking.Because the cylindricality refractory masses is by forming in conjunction with a collection of part, thereby forms easily.If this refractory masses is partly impaired, can only change impaired piece spare, simplified repair.
Each water cooling tube of being made by nonmagnetic substance is embedded among each the piece spare that constitutes the cylindricality refractory masses, forms independently aquaporin.The support plate of insulation is connecting each stainless steel tube simultaneously around the outside of these piece spares, maintains piece spare thus.Even water cooling tube is the magnetic flux heating, the temperature that is increased also seldom.Because water cooling tube is for the insulated bearing plate around the piece spare outside keeps reliably, can prevent that refractory material from dropping and the cracking of corner part.

In this induction heating equipment, when AC electric current supply solenoid 101, the just sensed heating of the heating target 102 of in heat tunnel 105, advancing continuously and the temperature of whole object is raise.The radiant heat that refractory masses 103 protection solenoids 101 are not heated to the plan heating target 102 of high temperature influences, and by water cooling tube 104 coolings that are embedded in the refractory masses 103.
Can be corrugated or have curved end by the heating target in the heat tunnel 105.When this curved end by heat tunnel 105, it against the sliding beam 117 outstanding from refractory masses 103 surfaces, has prevented that it from contacting with refractory masses 103 when advancing.Can prevent from like this to damage refractory masses 103, and need not stop work and repair or change refractory masses 103.
Even intending the oxide scale of heating plate is subjected to the attraction of solenoid 101 magnetic force and passes refractory masses 103, even perhaps refractory masses 103 is peeled off because of thermal shock formation crackle and is weighed down following time, because be provided with between refractory masses 103 and solenoid 101 all is the hard insulated bearing plate 108 that is formed by the glass layer casting die, the oxide scale just can not pass refractory masses 103, and can avoid the dielectric breakdown of solenoid 2.
In the above, be as insulated bearing plate 108 the glass layer casting die.But also can adopt other to have the material of proper strength and insulation property.
As shown in Figure 8, coverboard 115 is mounted to both end sides around solenoid 101.Form the Shell Plate 115 of the composite component of corrosion resistant plate 114 and water-cooled magnetic shield panel 112, can shield the magnetic flux that solenoid 101 produced by its water-cooled magnetic shield panel 112 and not leak.In this case, copper coin 110 has little temperature rise and good magnetic cup effect is provided, because it has low resistivity and is difficult for producing magnetic flux.Because copper coin 110 is by attached water-cooled copper 111 coolings thereon, just can reduce temperature rise.
Being subjected to induction heating is to be formed by the corrosion resistant plate with good thermal resistance to the surface portion of the housing department 115 of plan heating target 102 radiant heat of high temperature influence, and be by water cooling tube 113 coolings from the outside, with tight contact of magnetic shield panel of water-cooled it is cooled off internally again simultaneously, so just can form little temperature rise.That is to say, because the surface of water-cooled magnetic shield panel 112 is that it directly from the thermal radiation of intending heating target 102, so just only has little temperature rise with regard to minimum reception by corrosion resistant plate 114 shieldings with good thermal resistance.Even in continuous running, also do not have big thermal stress and act on the water-cooled magnetic shield panel 112, and the cooling water of the water-cooled copper 111 that causes of avoiding ftractureing is sewed.
As mentioned above, utilize induction heating equipment of the present invention, can stop plan heating target contact by sliding beam with refractory masses by heat tunnel, thereby steady operation for prolonged period of time.In addition, the dorsal part at refractory masses 103 is provided with very hard insulated bearing plate.So just supporting water cooling tube 113, and can prevent to cause solenoidal dielectric breakdown because of entering of oxide scale or similar impurity.

Subsequently, slinging with crane 228 is placed on the heater body 203A on the heater carrier 202A that separates on the power supply carrier 204 and it is removed, as shown in figure 18.Another heater body 203A that changes usefulness is loaded and is placed on the heater carrier 202A, so just finished replacing.When heater body 203A that will check another heater body 203B or adjacent induction heating equipment 201B and 203B, because adjacent induction heating equipment 201A to 201C is placed under the offset manner shown in Figure 19, just can guarantee the abundant big space that has the operator to work processing ease to be carried out.
In case change or check end, making 204 reaches of power supply carrier with regard to the rotating drive wheel.Power supply carrier 204 against on the heater carrier 202A that stops, and trailing wheel 209b is guided by an axle lifting guide 221 at it and is just moved upward, as shown in figure 14.Then, heater carrier 202A just is linked to be integral body with power supply carrier 204, travels forward, and turns back on the hot rolling line.
In the above description, two in the above the heater carrier 202A of having heaters main body 203A and 203B be connected a power supply carrier 204 with 202B.But one or three same power supply carrier of heater carrier is connected.
As mentioned above, according to induction heating equipment of the present invention, heater and RF high voltage source are integrally to adorn to invest on the carrier.When maintenance, induction heating equipment can be removed from the hot rolling line and repair or change.The hot rolling line need not stopped work, and can guarantee very big working space, can improve operability.
Heater body and power supply have constituted independently parts.In order to keep in repair, can withdraw from heater body and power supply from the hot rolling line.Heater body and power supply are separated and be transported to independently local so that repair or change.So just can improve operability more significantly.
Owing to be that the same power supply carrier of a collection of heater body is combined a shared RF high voltage source, the size and the energy permission equipment that just can reduce structure are stably advanced.When power supply carrier and heater carrier are connected when advancing, distribution of weight is positioned at the rear axle disorbit upstream then of the heater carrier of mid portion between front and rear wheel.Heavy equipment is stably travelled.
