Abstract
ABSTRACT OF THE DISCLOSURE
A guide trough for molten products includes an elongated long body of monolithic refractory material having a runway for conducting molten products in the top surface thereof, the body is supported by a pair of holding beams connected with supporting cross members disposed at intervals, and a hook engaging means provided by removing a part of the body and exposing the holding beams for engaging hook means.

Description
11~68~9 GUIDE T~OUGH FOR MOLTEN PRODUCTS
Field of the Invention . _ This invention relates to improvements in guide troughs to be used for conducting molten products from a melting furnace, such as a blast furnace and an electric furnace, and more particularly to a large size guide trough constructed in one block with monolithic refractory material.
Background of the Invention In the recent tendency of the art, a long guide trough is constructed by stamping monolithic refractory material in one block instead of being constructed by brickworks, and transported and settled in the place where it is to be used.
The method is also used for repairing the troughs, in which, when the inner surfaces of the troughs are worn by running molten products, whole of the trough is replaced with a new one instead of repairing by lining worn surfaces.
Such troughs are so heavy - some of them weigh about l ton or more - that the outside of the refractory body is reinforced by a supporting member, such as plates or frame works, which are usually provided with hook plates projecting upwards and having hook engaging holes for hanging the trough body.
As the hook plates are projecting upwards from the trough 11168~9 body, piling up of the troughs in the storage is hindered ~y these hook plates. Further, while in use, hook plates are exposed to the heat radiation and splashes of the hot running molten products, and this may weaken the hook plates S and cause damages.
Summary of the Invention The guide trough of the present invention includes a long trough body made of the monolithic refractory material and provided with a runway for conducting molten products in the top surface; a supporting means for supporting said trough body having a couple of holding beams buried at both side upper pRrt~ of said trough body and extending longitudinally, said holding beams being connected with supporting cross members disposed at intervals; and a hook engaging means provided by removing a part of said trough body and exposing the holding beams for engaging hook means. Thus the hook engaging means does not project out from the trough body so that the troughs may be piled up easily in the storage.
Further, the hook engaging means is not exposed to the heat radiation or splash of hot running molten products, so that the damages of the hook engaging means can be prevented.
The invention will be described in more detail with reference to the accompanying drawings.

Description of the Preferred ~mbodiment The trough shown in Fig.l-Fig.3 includes a long body 1 formed by stamping monolithic refractory material and provi-ded with a runway for conducting molten products in the top surface.
The body 1 is reinforced by a couple of holding beams 2 of cylindrical form buried at both side upper corners and extending longitudinally. The holding beams 2 are connected by U-shaped supporting cross members 3 disposed at intervals.
Hook engaging means 4 are provided at suitable portions of the body 1 by removing a part of body 1 and exposing the lil6849 holding beams 2 for engaging hook means.
The trough may be hung by engaging the hook 6 of the hanging members 5 such as shown in Fig.4 with a poxtion of the holding beam 2 in the hook engaging means 4, and thus S the trough can be transported.
The hook engaging means 4 are not projecting from the body 1 so that the troughs can be piled up easily in the storage. Further the hook engaging means 4 are not exposed to the heat radiation or splash of hot molten products run-ing through the runway of body 1, so that the damages of thehook engaging means can be prevented.
Pipings, flat or angle bars may be used for the holding beams 2. Also connecting members 7 may be used for connect-ing and securing supporting cross members 3 at the bottom of the body 1 as shown in Fig.3.
Fig.5-Fig.7 shows a trough of another embodiment of the present invention, in which two flat bars 8 and 8' are used as a holding beam 2'.
Flat bars 8 and 8' are piled up together with a reinfor-cing member such as wire nettings 3' therebetween which islined inside of the supporting cross members 3. Wire net-tings 3' are secured to the flat bars 8 and 8' with bolts 9, and supporting cross members 3 are welded to the outside bar 8.
