    摘要: A plug for the tap hole of a metallurgical vessel includes a canister containing refractory mortar between a pair of end plates, one of which is movable toward the other to squeeze or compress the mortar through an aperture in a generally radially outward direction to seal against the tap hole wall. A plunger is provided and has axially relatively movable sleeves. One sleeve connects with the plug, while the other sleeve has a pusher head engageable against the movable end plate of the plug. The plug is connected to the plunger and inserted into the opening. The sleeves are axially displaced to cause the disks to relatively move axially toward one another, displacing the mortar into sealing engagement with the tap hole walls. Upon location and sealing of the tap hole by the plug, the plunger is unscrewed from the plug and withdrawn for later use.

    摘要: An exothermic composition comprises a particulate readily oxidizable metal such as aluminium, magnesium or silicon and an organic fluorine-containing compound, and usually an oxidizing agent for the readily oxidizable metal. The preferred organic fluorine-containing compound is polytetrafluoroethylene. The composition may also contain a binder, a particulate refractory material, refractory fibres and/or organic fibres. The composition may be used in the casting of molten metal, either in particulate form or as a preformed shape such as a sleeve or board, to cover or surround molten metal in the feeder of a casting mould or in the head or head box of an ingot mould.

    摘要: A cavity in a body of particulate moulding material has at least one rib-like formation for gripping an object received in the cavity. In the case of a metal casting mould a riser sleeve (1) is inserted into a cavity (9) in the top part of the mould and the cavity (9) is produced by means of a tapered former (5) the exterior of which has a plurality of radially spaced apart recesses (6) extending between the top and towards the bottom of the former and which has a negative taper from bottom to top. The depth of the recesses (6) is such that circles geometrically inscribed inside the base of the recesses (6) have diameters smaller than the corresponding mean outside diameters less three times the standard deviation of the riser sleeves (1) to be used. The recesses (6) form ribs (11) from the moulding sand and the ribs (11) grip the outer surface of the sleeve (1).

    摘要: A binder composition in aqueous solution, suitable for use in the production of foundry sand moulds and cores is obtained by mixing(i) an alkali silicate(ii) a substantially water soluble carbohydrate selected from monosaccharides, disaccharides, polysaccharides and derivatives thereof and(iii) a phenolic compound selected from monohydric phenols, dihydric phenols, trihydric phenols, phenols of polynuclear hydrocarbons and phenolic acids, which is miscible with or soluble in an aqueous solution of an alkali metal silicate.The composition may also contain an oxyanion such as a borate which is capable of forming a water soluble complex with the carbohydrate.A mixture of phenolic compounds, such as a mixture consisting predominantly of isomers of di- and trihydroxy diphenyl obtained in the distillation of crude resorcinol, may be used.The preferred carbohydrate is a stabilized starch hydrolysate whose reducing power has been removed by a process such as hydrogenation.

    摘要: Treatment agents are described for use in nodularizing cast iron in the production of ductile iron and also useful in deoxidizing steel and desulphurizing cast iron. The agents take the form of a compacted mixture comprising particulate iron, magnesium and calcium, and are distinguished by(a) a magnesium content of 5 to 15% by weight(b) a weight ratio of magnesium to calcium in the range of from 1:1 to 8:1(c) the iron having a purity of at least 95% by weight and a particle size of all less than 0.5 mm and(d) being compacted into a body of density at least 4.3 gm/cm.sup.3.The high density allows the agent to be used effectively by a simple overpour technique.
