摘要： In order to avoid solidification which proceeds over the meniscus of the metal mirror during the continuous casting or remelting of steels and alloys, the cooling conditions are set in such a way that, in the case of inlet temperatures of the coolant at room temperature or else considerably thereabove, outlet temperatures of the coolant of at least 80°C are achieved. Suitable coolants are pressurized water, metals which are liquid below 100°C and also ionic liquids (salt melts) which are liquid above room temperature and up to at least 200°C, it being possible for the differences in temperature between the coolant inlet and the coolant outlet in the mould to be between 5°C and 150°C.

摘要： The invention concerns the method for reprocessing of aluminium slag. Novelty of the method is that the reprocessing of the aluminium slag is performed in electro-slag furnace with the crucible with the bottom electrode as a cathode and the top electrode as an anode. The melting and dissolution of the slag occur at the temperature in the range of 800-2000 °C. The cryolite (Na3AlF6) and the alumina (Al2O3) are loaded into the crucible of electro-slag furnace and melted, then into the obtained liquid melt (electrolyte) the crushed aluminium slag (mechanical mixture of Al2O3 and aluminium metal) and the cryolite are charged by portions with melting and dissolution thereof in the electrolyte. The extraction of liquid metal aluminium occurs on the bottom of the crucible, in the area of cathode, and the extraction of secondary slag as mixture of cryolite and alumina occurs in the area of the anode, after which the discharge of the metal and the secondary slag is carried out. Method allows almost complete separation of metallic fraction and oxide fraction of the aluminium slag, the extraction of metal being up to 99%. The received metal aluminium and/or aluminium alloy can be used for the production of aluminium alloys, and the received secondary slag in form of mixture of cryolite and alumina is usable as a raw material for production of primary aluminium by electrolysis.

摘要： Joining process 100, joined article 501, and process of fabricating a joined article 501 are disclosed. The joining process 100 includes providing a consumable electrode 101 comprising a first material 103 and a second material 105, melting the consumable electrode 101 by a current-induced melting or remelting, and re-solidifying the first material 103 and the second material 105 to form a dissimilar ingot 109 having a first region 119 being a re-solidification of the first material 103 and a second region 121 being a re-solidification of the second material 105. The joined article 501 includes the first region and the second region; the dissimilar ingot 109 at least partially defines the joined article. The process of fabricating includes providing the dissimilar ingot 109, positioning the dissimilar ingot 109 within a die, and applying force from the die to compress the dissimilar ingot 109, thereby forming the joined article 501.

摘要： The present invention relates to a method for producing a martensitic stainless steel that includes a step in which an ingot of the steel is remelted under a layer of slag, followed by a step in which the ingot is cooled. Before the skin temperature of the ingot resulting from the slag remelting step drops below the martensitic transformation temperature M
s of the steel, the ingot is placed in a furnace, the initial temperature T
0 of which is then above the cooling‑induced pearlite transformation finish temperature Ar1 of the steel. In the furnace, the ingot is subjected to a homogenization treatment at least for a holding time t after the temperature of the coolest point in the ingot has reached a homogenization temperature T, said holding time t being equal to at least one hour and the homogenization temperature T varying between approximately 900°C and the burning temperature of the steel.
