Specific embodiment
The present invention is further described with reference to the accompanying drawings and detailed description.
Intermediate frequency furnace lining repairing method, characterized by the following steps: A, the damage for removing intermediate frequency furnace 1
Bad furnace lining, reservation do not damage furnace lining 2, then to clearing up inside intermediate frequency furnace 1；B, repairing mold is put into Medium frequency induction
In furnace 1, repairing mold includes the first die assembly 3 and the second die assembly 4；First die assembly 3 and the second die assembly 4 are
Including two side plates, 8, connection bar assemblies 9 and two adjusting bar assemblies 10；8 shape of side plate is arc, and two side plates 8 are opposite
Setting；Connection bar assembly 9 and adjusting bar assembly 10 are arranged in the same direction and between two side plates 8, connect bar assembly 9 and two are adjusted
Bar assembly 10 is set gradually from top to bottom；Connecting bar assembly 9 includes connection rod set 9-2 and two connecting rod 9-1, two connecting rods
9-1 is connect with two side plates 8 respectively, and two connecting rod 9-1 are inserted into connection rod set 9-2 from both sides and are axially movable, connecting rod
It is connected with lifting lug 9-4 and Top fastening screw 9-3 on set 9-2, Top fastening screw 9-3 holds out against connecting rod 9-1；Adjusting bar assembly 10 includes adjusting
Pole covers 10-2 and two adjusting rod 10-1, and two adjusting rod 10-1 connects with two side plates 8 respectively, and two adjusting rod 10-1 divide
Does not adjust by oppositely oriented threaded connection with the both ends of adjusting rod set 10-2 and be provided with rotational structure on rod set 10-2, two
A adjusting rod set 10-2 is connected by chain drive structure 11 enables two adjusting rod set 10-2 synchronous rotaries；First set of molds
The connection bar assembly 9 and adjusting bar assembly 10 of part 3 are located at the lower part of side plate 8；The connection bar assembly 9 and tune of second die assembly 4
Pole component 10 is located at the top of side plate 8；Two side plates 8 of the first die assembly 9 and two side plates 8 of the second die assembly 4
Form circular repairing mold side plate 7；The space between furnace lining 2 and mold side plate 7 is not damaged as repairing space 5；C, it is repairing
Patching material is added in space 5, material to be repaired repairs mold with dismounting after furnace lining 2 is combined is not damaged.
The present invention only removes damage furnace lining, and reservation does not damage furnace lining 2, although operation difficulty, which increased, can save greatly
Patching material is measured, cost is saved.It is adjustable to repair mold, is put into intermediate frequency furnace after first turning repairing mold down, then adjust
Greatly, repairing mold can be facilitated to be put into intermediate frequency furnace.
After repairing mold is put into intermediate frequency furnace 1, the concrete operations for adjusting the first die assembly 3 are as follows: firstly, in
Upper padding plate is padded in the bottom of frequency induction furnace 1, will or hang the first die assembly 3 by lifting lug 9-4；Then, rotation adjusting lever
10-2 is covered, under the action of reverse thread, two adjusting rod 10-1 stretch out, so that side plate 8 is displaced outwardly, side plate 8 is mobile in place,
First die assembly 3 is adjusted and is completed.The operation for adjusting the second die assembly 4 is identical as the operation of the first die assembly 3 is adjusted.
In place, repairing mold side plate 7 is formed the movement of four side plates 8.
The effect that first die assembly 3 and 4 component of the second mold all have two adjusting bar assemblies 10 is to avoid side plate 8 single
Point driving, to prevent the side plate being likely to occur 8 from rotating centered on connecting bar assembly 9.Two adjusting bar assemblies 10 are in chain conveyer
Synchronous driving side plate 8, can avoid side plate 8 and is rotated centered on connecting bar assembly 9 under the action of structure 11.
" the connection bar assembly 9 and adjusting bar assembly 10 of the first die assembly 3 are located at the lower part of side plate 8；Second die assembly
4 connection bar assembly 9 and adjust the top that bar assembly 10 is located at side plate 8 " effect be to avoid the first die assembly 3 and the second mould
Have component 4 to interfere.Obviously the first die assembly 3 first should be put into intermediate frequency furnace 1, then places into the second die assembly 4.
As shown in Figure 1, there is gap, patching material may be leaked from the gap between four side plates 8 after the completion of adjusting
Out, under type such as can be used to avoid: is all connected on two side plates 8 of the second die assembly 4 there are two liner plate 6, two liner plates 6 divide
Not Wei Yu side plate 8 two sides inside.After the completion of mold is adjusted, liner plate 6 is lining in 8 inside of side plate of the first die assembly 3, blocks
Above-mentioned gap.
