Abstract
The utility model discloses a kind of heat treatment for medium plate stove hearth roll cleaning plant, to solve the not good problem of current hearth roll cleaning plant cleaning effect.It comprises a block plate, and upper surface of steel plate is equipped with hook, and lower surface of steel plate interval has many parallel grooves, and the protruding block lower surface in the middle of adjacent grooves is the cancave cambered surface adapted with hearth roll excircle cambered surface, and bottom portion of groove both sides are fillet.The utility model lower surface is cancave cambered surface, fits completely, effectively increase contact area with hearth roll roll surface, while guarantee cleaning effect, avoids causing secondary damage to roll surface in scale removal process; Form larger shearing force by the counter motion of steel plate and hearth roll, improve cleaning effect, even if when lower lobes block has small part to damage, still reusable, can not hearth roll be damaged; Bottom portion of groove both sides are fillet, be convenient to thoroughly cleaning scrape into iron scale, knob, larger spatial accommodation is provided, increases work efficiency.
Description
Technical field
The utility model relates to a kind of heat treatment for medium plate stove hearth roll cleaning plant.
Background technology
Heat-treatment furnace is one of nucleus equipment that in hot continuous rolling, the steel product such as plate, cut deal is produced, heat-treatment furnace is generally roller hearth type heating furnace, when normally producing, steel plate at the uniform velocity transmits by the process system of setting and moves ahead on roller track, heat time terminates rear steel plate automatic tapping, completes heating process in the stove.Hearth roll is hollow roll, when in-furnace temperature reaches more than 200 DEG C, its resistance of deformation obviously declines, transmit in the process of steel plate at frictionally, the inferior or burner uneven heating of combustion gas quality, lower surface of steel plate iron scale the reason such as to peel off and hearth roll surface all may be caused to form temporary sticky object or more firm wart like structure.Adhesive is cleared up not in time, and under the pressure of high temperature thick steel plates, likely process and firm gradually in time, and the knob produced because of burning, then progressively expand along with continuous heating process and worsen, finally forms scar projection and obstinate dross.
The scar projection of roller surface and dross cause the main reason of the defects such as surface of steel plate scuffing, roll marks, pit, therefore, be an important process of heat processing section to the cleaning on hearth roll surface, its treatment effeciency directly affects operating efficiency and the economic benefit of heat-treatment furnace.Application number is the Chinese patent " a kind of device of cleaning roller bottom type normalizing furnace roll surface " of CN 20120569732.9; disclose the device that furnace sow removed by a kind of straight plate; it is characterized in that below flat plate, open a yi word pattern groove, remove furnace sow by the cutting force of contact friction.But the grooved of this device is the square groove of vertical corner angle, impurity enters folding corner region not easy to clean after square groove; And the contact of itself and roll surface is linear contact lay, compared with the pure-surface steel plate not digging groove, cleaning effect does not have advantage.
Summary of the invention
The purpose of this utility model is to overcome prior art defect, provides a kind of heat treatment for medium plate stove hearth roll cleaning plant.
The technical solution of the utility model is achieved in that a kind of heat treatment for medium plate stove hearth roll cleaning plant, comprise a block plate, upper surface of steel plate is equipped with hook, lower surface of steel plate interval has many parallel grooves, it is, the protruding block lower surface in the middle of adjacent grooves is the cancave cambered surface adapted with hearth roll excircle cambered surface.
Preferably, bottom portion of groove both sides are fillet.
Preferably, groove length is substantially suitable with hearth roll face length.
The utility model lower surface is cancave cambered surface, fits completely, effectively increase contact area with hearth roll roll surface, while guarantee cleaning effect, avoids causing secondary damage to roll surface in scale removal process; Form larger shearing force by the counter motion of steel plate and hearth roll, improve cleaning effect, even if when lower lobes block has small part to damage, still reusable, can not hearth roll be damaged; Bottom portion of groove both sides are fillet, be convenient to thoroughly cleaning scrape into iron scale, knob, larger spatial accommodation is provided, increases work efficiency.
Accompanying drawing explanation

Fig. 2 is utility model works front view.
Fig. 3 is utility model works top view.
In figure, 1-steel plate; 2-links up with; 3-groove; 4-protruding block; 5-hearth roll.
Detailed description of the invention
Be further described below in conjunction with accompanying drawing:
As shown in Figure 1, Figure 2, Figure 3 shows, a kind of heat treatment for medium plate stove hearth roll cleaning plant, comprise one block of straight rectangle steel plate 1, steel plate 1 upper surface corner is respectively equipped with a hook 2, steel plate 1 lower surface interval has many parallel grooves 3, protruding block 4 lower surface in the middle of adjacent grooves 3 is the cancave cambered surface adapted with hearth roll 5 excircle cambered surface, effectively increases contact area; Groove 3 two bottom sides is fillet, is convenient to clear up accumulated slag; Groove 3 length and hearth roll 5 face length are substantially suitable, can ensure that scale removal process is without dead angle, more thorough.During making, select steel plate 1 thickness to be 80mm, length is 6000mm, and width is more smaller than hearth roll 5 face width, and 30mm is lacked respectively in both sides, and steel plate 1 lower surface groove 3 is made by machining.
Concrete cleaning operation step is as follows:
1) after a heat treatment cycle terminates, steel wire rope one end is hung up properly on the utility model one hook 2, the steel wire rope other end twists on the hoist engine of fire door, and the utility model is loaded heat-treatment furnace from entrance, rotates progressively be sent to stove tail with hearth roll 5;
2) after confirming that the utility model is sent to stove tail, start fire door hoist engine, keep hearth roll 5 to press normal mode to rotate, steel wire rope is pulled toward process stove Way in the speed of 0.5-1m/min, until move treating apparatus to porch, a cleaning cycle completes, and now the furnace sow of hearth roll 5 is mostly scraped;
3) look the production load etc. of hearth roll 5 useful life, heat-treatment furnace, above cleanup step can be repeated;
4) after cleaning operation thoroughly completes, the utility model is taken out, turn-over, remain or other residues with the iron scale piled up in reinforcing bar removing groove 3, wart like structure in time, keep this space clean and tidy, treat next use.
Claims (3)
1. a heat treatment for medium plate stove hearth roll cleaning plant, comprise a block plate, upper surface of steel plate is equipped with hook, and lower surface of steel plate interval has many parallel grooves, it is characterized in that: the protruding block lower surface in the middle of adjacent grooves is the cancave cambered surface adapted with hearth roll excircle cambered surface.
