  • Gas seal assembly
    Patent number: 7758051
    Abstract: A gas seal assembly includes a pair of mutually rotatable sealing members, each of which has a front face adjacent a gap between the two members which constitutes a leakage path through the seal assembly. The two sealing member are urged, in use, in a direction to close the gap and a gas bleed arrangement is provided for allowing gas from a high pressure side of the seal to bleed into the gap so as to apply a force tending to separate the members. The gas bleed arrangement includes a bore extending between the front face and a rear face of one of the sealing members, a generally radial groove formed in the rear face of the sealing member and a plate overlying the rear face to cover the groove and thereby define between the rear face of the sealing member and the plate a bleed passage connecting the bore to the high pressure side of the seal.

  • Method in connection with steel production
    Patent number: 7744674
    Abstract: A method of producing a fluxing agent that can be used in production of steel, preferably stainless steel, employs as a raw material a hydroxide sludge that results from neutralization of metal-contaminated pickling liquid from a pickling step for a steel and contains at least one fluoride-containing compound. The hydroxide sludge is calcined. Steel, preferably stainless steel, is produced by decarburizing a steel heat, whereby a slag is formed on top of the steel heat, and adding a fluxing agent to the slag.
