  • Publication number: 20210040634
    Abstract: A method for producing a metal porous body includes the steps of: performing electrical conduction treatment on a surface of a skeleton of a sheet-like resin porous body having the skeleton with a three-dimensional network structure, to obtain a conductive resin porous body having a conductive layer; performing electroplating treatment on a surface of a skeleton of the conductive resin porous body to obtain a plated resin porous body having a metal plating layer; and performing treatment of removing at least the resin porous body from the plated resin porous body to obtain a metal porous body.

  • Patent number: 4430116
    Abstract: An apparatus for heating or heating and reduction raw material of a metallurgical furnace, utilizing high temperature waste gases which are released from the same furnace, has one or plural numbers of reactor(s) capable of holding the raw materials in the amount which can be charged in plural numbers of processing in the metallurgical furnace, where the reactor(s) is (are) disposed on a bypass passage connected to a pipe of a waste gas processing apparatus for cooling and scrubbing the waste gases from the metallurgical furnace. A part or all the waste gases are introduced into the reactor(s) and come into contact with the raw materials therein when the blowing in the furnace is performed to a full scale, and the reactor is cut off at the initial and final stage of blowing, whereby the heating or the heating and reduction raw material of a metallurgical furnace is effectively performed.

  • Patent number: 4153454
    Abstract: Steel materials having an excellent hydrogen induced cracking resistance when used under atmosphere containing H.sub.2 S, which contain 0.05 to 0.20% of C, 0.01 to 0.50% of Si, 0.60 to 2.00% of Mn, 0.01 to 0.10% of Al, less than 0.0020% of S, Ca of 0.0020% to less than 0.0050%. These steel materials are increased in the tensile strength by additionally containing at least one of Cu, Ni, Cr, B, Mo, Nb, V, Zr and Ti. Furthermore the effect of addition of Ca is stabilized by adding rare-earth elements.
