摘要： The present invention relates to an arrangement and method that help to reduce the build-up formed on the grate of a fluidized-bed furnace in the roasting of fine-grained material such as concentrate. The concentrate is fed into the roaster furnace from the wall of the furnace, and oxygen-containing gas is fed via gas jets under the grate in the bottom of the furnace in order to fluidize the concentrate and oxidize it during fluidization. Below the concentrate feed point, or feed grate, the oxygen content of the gas to be fed is raised compared with gas fed elsewhere using additional gas jets situated in the feed grate higher than the other jets. The extra jets of the feed grate are connected to their own gas distribution unit.

摘要： The invention relates to a method for producing magnetically active shape memory metal alloy, said metal alloy containing nickel, manganese and gallium. In the method, the different components of the metal alloy are melted, and the melt is homogenized essentially at the melting temperature; the obtained metal alloy is cast, and the cast metal alloy is subjected to directional solidification at 10-100° C. below the liquidus temperature of said metal alloy.

摘要： The present invention relates to method, which helps to reduce and remove the build-up forming on the grate of a fluidized-bed furnace in the roasting of fine-grained material such as concentrate. The concentrate is fed into the roaster from the wall of the furnace, and oxygen-containing gas is fed via gas nozzles under the grate in the bottom of the furnace in order to fluidize the concentrate and oxidize it during fluidization. Below the concentrate feed point, or feed grate, the oxygen content of the gas to be fed is raised compared with the oxygen content of the gas fed elsewhere.
