Abstract

The invention relates to the construction of heating furnaces operating in rolling mills and ensuring the issuance of slabs from the furnace and their supply to the rolling table of rolling mills, and can be used in the metallurgical and engineering industries. The purpose of the invention is to improve the quality of heating and reduce heat loss by reducing the height of the discharge window. The device contains a hinged-lever mechanism of movement, inclined sklizy, rods with stops, pivotally connected to the trolley and drive, while the trolley has a shock absorber. Parallel to the axis of the rollers of the roller table, guide copiers are installed, the ends of which are made at an angle equal to the angle of inclination of the rods. The rollers of the trolley are in constant contact with the copiers. The drive includes a cable drive with an electric winch. 3 hp f-ly, 2 ill.

Description

The invention relates to the design of heating furnaces of rolling mills, in particular, to the design and placement of receiving and unloading devices of methodical furnaces with end face, equipped with inclined edges.

The purpose of the invention is to improve the quality of heating and reduce heat loss by reducing the height of the furnace discharge window.

FIG. I shows a device for unloading slabs from a furnace, longitudinal section; in fig. 2 - the same, top view.

The device for unloading the slab from the furnace contains a hinge-lever mechanism 1 for moving, inclined slide 2, shtangi 3 with stops 4, hingedly connected to the trolley 5. equipped with road rollers 6 and shock absorber 7, drive 8 pivotally connected to the end of the rod 3 with the control - by the control apparatus 9, the guide copiers 10, the ends of which are made at an angle equal to the angle of inclination of the rods, are set to

between the rollers. 12 roller tables parallel to the axis of the rollers. The drive 8 of the reciprocating movement includes a cable drive 13 with an electric winch 14.

The device works as follows.

In the initial position, the boom 3 is at the lowest point, the carriage 5 is below the level of the rollers 12 of the receiving roller table, preventing the transport of heated slabs from other furnaces through it, and the running rollers 6 of the carriage 5 are on the projecting guide copiers 10

The command device 9 gives impetus to the actuator 8 and through the electric winch 4 and the cable transmission 13 acts on the hinged-lever drive I and Staigi 3:

At the beginning of the movement of the rods, the carriage 5 is parallelly lifted above the level of the rollers 12 of the receiving rods by moving its track rollers 6 along inclined surfaces of protruding ends

; Upon further movement of the rods 3 x | one rollers 6 of the carriage 5, they move the rjo section of the guide copiers 10 that are not parallel to the trajectory of the rods, in particular, along a horizontal one. by means of a hinge, lifting and turning the trolley 5 in the dry zone through the window 15 of the heating Nechi, ensuring a minimum height of about 15 of the dispensing.

} In the extreme upper position of the slider 3, the trolley 5 is below the U1 level of the inclined platform 2, above which only the shock absorber 7 projects. In this position, the command device 9 gives a pulse to turn on the furnace pusher (not shown).

When pushing the slab through the heating furnace with a pusher, the heated front slab 5 is pushed onto the inclined sides 2, where it stops and is held by the shock absorber 7; trolley 5, after which the command device 9 is given an impulse and pushing of the charge stops. The subsequent heated slab 16 remains Ua to the stove 17 bottom, and the distance from the delivery window 15, equal to Less than half the slab width, and the placement of it does not occur.

i Lowering the trolley 5 with the slot 18 pro and (: walks in the opposite direction by means of the hinges of the lever mechanism 1 and the drive 8. In the position when the trolley 5 descends to the level of the roller table, the comaid machine 9 will give an impulse to slow down

5, the stroke of the drive 8, and slab 18 smoothly, without impact, is placed on the rollers 12 of the receiving roller table, and the carriage 5 descends below the level of the rollers 12 to the initial position. non-obstruction of slave transportation
