Definitions
- 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.
- a ling 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 1 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.
- 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.
- hook plates are projecting upwards from the trough body, hook plates are exposed to the heat radiation and splashes of the hot running molten products while in use, and this may weaken the hook plates and cause damages. Further, piling up of the troughts in the storage is hindered by such projections.
- 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 sai6 trough body having a couple of holding beams buried at both side upper corners 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.
- a strong and rigid supporting and hook engaging means may be provided, as well as the hook engaging menas does not project out from the trough body, so that it is not exposed to the heat radiation nor splashes of hot running molten products and the damages thereof can be prevented absolutely. Also, the troughs may be piled up easily in the storage.
- 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 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 portion of the holding beam 2 in the hook engaging means 4, and thus 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 runing through the runway of body 1, so that the damages of the hook engaging means can be prevented.

Abstract
Description
- 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.
- In the recent tendency of the art, a ling 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 1 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 body, hook plates are exposed to the heat radiation and splashes of the hot running molten products while in use, and this may weaken the hook plates and cause damages. Further, piling up of the troughts in the storage is hindered by such projections.
- 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 sai6 trough body having a couple of holding beams buried at both side upper corners 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 a strong and rigid supporting and hook engaging means may be provided, as well as the hook engaging menas does not project out from the trough body, so that it is not exposed to the heat radiation nor splashes of hot running molten products and the damages thereof can be prevented absolutely. Also, the troughs may be piled up easily in the storage.
- The invention will be described in more detail with reference to the accompanying drawings.
-
- Fig.l is a side view of a trough according to the present invention;
- Fig.2 is a cross-sectional view taken along line X-X of Fig.l;
- Fig.3 is a top plan view of the trough in Fig.l;
- Fig.4 is a partial front view showing one example of hook means;
- Fig.5 is a side view of a trough of another embodiment of the present invention;
- Fig.6 is a cross-sectional view taken along line Y-Y of Fig5;
- Fig.7 is a top plan view of the trough in Fig.5.
- 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. Theholding beams 2 are connected by U-shaped supportingcross 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 theholding 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 portion of the
holding beam 2 in thehook engaging means 4, and thus 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 thehook engaging means 4 are not exposed to the heat radiation or splash of hot molten products runing through the runway of body 1, so that the damages of the hook engaging means can be prevented. - Pipings, flat or angle bars may be used for the
holding beams 2. Also connectingmembers 7 may be used for connecting and securing supportingcross 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 reinforcing member such as wire nettings 3' therebetween which is lined inside of the supportingcross members 3. Wire nettings 3' are secured to theflat bars 8 and 8' withbolts 9, and supportingcross members 3 are welded to theoutside bar 8.
