GUIDE TROUGHS FOR MOLTEN PRODUCTS

Document Type and Number:

WIPO Patent Application WO/1979/000550

Kind Code:

A1

Abstract:

Guide troughs for leading molten products tapped from blast furnaces or electric furnaces or the like. A lengthy trough body (1), formed in one block with monolithic refractories, is provided with hook-engaging means in order for the body to be lifted and transported. The hook-engaging means comprises supporting pipes (2) which are laid longitudinally in the upper portion of the body on both sides thereof; supporting transverse members (3) which are disposed in an appropriately spaced-apart relationship to interconnect the supporting pipes on both sides of the trough body; and cut-out portions (4) provided in the trough body at suitable locations to expose the supporting pipes (2) to be engaged by hooks. The fact that the trough body has such stout supporting means and hook-engaging means which does not project from the upper surface of the trough body as the suspension plates in the conventional guide trough of this type, allows the following advantages to be obtained. Namely, the hook-engaging means is protected against radiant heat and splashing from high temperature molten products flowing through the trough. This greatly enhances safety during transportation. In addition, as there are no objects projecting from the upper surface of the trough body, the guide troughs can be stored by stacking. This permits a reduction in storage space.
