Abstract: The invention relates to a refractory for cast molding to be used as, for example, lining of a molten metal container, which contains a proper amount of an organic foaming agent generating an incombustible gas upon decomposition, such as 4,4-oxybis(benzenesulfonohydrazide). This refractory can solve the conventional problem of explosive cracking to be caused upon drying the refractory by heat.

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.

Abstract: A method of spraying in amorphous refractory material, wherein, in order to prevent the refractory material from spattering during the spraying and to prevent coatings from splitting, a surface to be sprayed is surrounded with a screening member provided with air discharge holes such as a metal net. Refractory material is injected into a cavity surrounded with the screening member, whereby the air is carried outside through the discharging holes and only the refractory material is condensed and accumulated unto the surface to be sprayed surrounded with the screening member so that a rigid, thick coating adheres coherently to the surface.
