摘要： Methods (and products produced by the methods) are disclosed for sealing the cut end (13) of a concrete reinforcing bar (10, 56) or other long product that comprises a core (12) of mild steel or other corrosion susceptible metal and a cladding (14) of stainless steel or other corrosion resistant metal bonded to an axially extending outer face of the core. The methods include the steps of providing a cap (20, 50, 80) of corrosion resistant material such as stainless steel or a plastics material, and shaped so that it can be mounted on the cut end of the long product with the exposed portion (18) of the core enclosed by the cap. The cap has a skirt (24) that overlies the cladding adjacent the cut end. A seal is formed in various ways between the skirt and the cladding. The seal may be formed by filling the space between the cut end and the cap with resinous sealant (26) inserted in the cap before it is mounted over the cut end. In the case of a metal cap voids (30) in the sealant are removed by deforming the cap (22') after it is mounted over the cut end to reduce the volume of the space enclosed by the cap. The sealant may alternatively be a solder (52) or the like. The skirt of a metallic cap may be crimped, swaged, forged or welded to the cladding.

摘要： A method of producing a corrosion resistant ferrous product is disclosed. The product is produced by rolling a heated billet which comprises a mass of mild steel swarf in a stainless steel jacket. Two reducing agents are present in the jacket when the billet is heated. The first reducing agent is in the form of powdered aluminium, titanium turnings or other metal having a greater affinity for oxygen than chrome and which promotes the formation of CO rather than CO2 from air or oxygen which enters or evolves in the billet above about 800 °C. The second reducing agent is in gaseous or vapour form substantially below that temperature. The second reducing agent may be provided by premixing with the swarf such substances as ammonium chloride or urea, which dissociate to form reducing gases when heated. Alternatively, the billet can be heated in a reducing furnace and the gas in the furnace may act as the second reducing agent.
