Description

"Water-cooled sliding bar, especially for pusher-type furnaces" addition to Patent .................

(Note W 33 068 VI / 18c) 9 @@ The main patent relates to a water-cooled Sliding bars, especially for butts, with between the cooling pipe and the highly heat-resistant Attachment pieces pressure-resistant, heat-insulating intermediate pieces are arranged, the frame-like holders placed on the heating tube, which do not take up any pressure be included.

The slide bars designed according to the main patent have done well preserved. The goods treated in stoppers equipped with such sliding bars is evenly warmed through and no longer shows the dreaded black stripes in the area of the slide rail.

In the event of overheating, there is a risk that the slab on the according to the main patent loosely on the heat-insulating spacers in the holders attached top piece sticks, so Aass it under certain circumstances with the loose on the Cooling tube attached to the holder with an inclined surface for tilting each The discharge end of the StoB furnace equipped with the last slab follows the tilting movement, whereby it with if necessary the holder and the slab from the furnace.

.

The invention is now a development of the slide rail after Main patent and consists initially in the last holder, whose total length is at least corresponds to the lifting length of the widest slab, against lifting from the cooling tube or Secure tilting.

According to the invention, this security can be achieved by the attachment pieces with the holders, for example by means of a dovetail-shaped design of the upper one Part of the holder with the foot of the resting on the insulating spacers Cane be clamped. ' .

The holder on the cooling pipe can be secured by bolts that hold the KUhlrohr and these comprehensive side walls of the top floors under mediation a pipe sealed on the ihlrohr, for example by welding or by attachments on the cooling pipe, on which the top sections with slots in the side walls be pushed on like a bayonet.

The invention also relates to all of the longitudinal walls to provide the holder lined up on the cooling pipe with refractory ramming material, the bottom is held by a long approach.

Such insulation is more durable than the known ones suspended refractory panels.

Furthermore, the invention consists in the front end wall dect holder seen in the direction of impact and one leg resting against this end wall of the top section with vertical, preferably more dovetail shaped Tongue and groove to be provided * This is both a safeguard against lateral displacement des Aufaatzattiokes ale also achieved such against lifting.

The invention was illustrated by way of example in the drawings.

Figure 1 is a vertical partial longitudinal section through an according to the invention trained cooling bars. yigwr 2 is a vertical beanitt after Line II-II of Pigur 1.

On the cooling pipe 1 is the metallic holder 3, which is the Kührlrohr includes below with side cheeks 4, put on.

The holder 3 is stiffened by transverse walls 5, 6, 7 so that in connection with the longitudinal walls 8 pockets 9 arise in the heat-insulating spacers 10, preferably prints refractory bricks with a high density, are incorporated, and which rest directly on the refrigerator 1.

The middle transverse wall 6 and the front transverse wall in the direction of impact 5 end @ben a little below the intermediate pieces 10, so that the longitudinal beam-like The foot 11 of the top section 12 rests only on the intermediate pieces 10. The front one Transverse wall 5 is connected with a vertical bar 13, which is in its groove 14 a leg 15 of the Aufsatsstückes 12 engaging spring.

The side walls 8 of the holder 3 are chamfered outwards at the bottom and provided with an upwardly extending longitudinal extension 16. On this approach 16 and between the rib-like protruding transverse walls 5, 7 of the holder 3 is one Refractory ramming mass 21 brought.

The last three or four holders 3 at the discharge end, their total length corresponds to the widest slab, are detachably connected to the cooling tube in such a way that that they do not move vertically when the last slab is tipped or lifted off can do. In the exemplary embodiment, the holder 3 is by means of the side cheeks 4 by a bolt 22 which penetrates a sealing tube 23 welded to the cooling tube 1, attached to the cooling pipe.

The PuB 11 of the article 12 of the last three. or four holders 3 is wholly or partially widened in the shape of a dovetail and into the In this area, appropriately designed guidance of the two longitudinal walls 6einesohobeUtaj that the top sections 12 are also secured against lifting off the hold @ 3.
