20 Oct 1965TL;DR: In this paper, a stainless steel clad sheet material is formed by a gas diffusion type heat treatment of an arrangement of blanks consisting of ferrous sheets having a single surface coated with a chromium containing powder, each side of the finally coated sheet material will have a substantially equal coating of dense, pore free stainless steel material overlain on the matte surface coating side by a somewhat porous layer of stainless steel.
Abstract: A stainless steel clad sheet material having a bright, or reflective, surface coating on one side and a matte, or dull, surface coating on the opposite side is formed by a gas diffusion type heat treatment of an arrangement of blanks consisting of ferrous sheets having a single surface coated with a chromium containing powder. Each side of the finally coated sheet material will have a substantially equal coating of dense, pore free stainless steel material overlain on the matte surface coating side by a somewhat porous layer of stainless steel material.

09 Jul 1965TL;DR: In an effort to compete with the high productivity of the LD basic oxygen process, more and more open-hearth operators have been resorting to oxygen lancing. But along with the increased productivity made possible by oxygen lance, there is also the heavy, dark reddish ironoxide plume that accompanies the furnace waste gas as discussed by the authors.
Abstract: In an effort to compete with the high productivity of the LD basic oxygen process, more and more open-hearth operators have been resorting to oxygen lancing. But along with the increased productivity made possible by oxygen lancing, there is also the heavy, dark reddish iron-oxide plume that accompanies the furnace waste gas. Dry precipitators and wet scrubbers are among the techniques that have been developed to eliminate this plume. This summary article—based on papers presented at the 47th National Open Hearth and Basic Oxygen Steel Conference—describes such waste-gas cleaning systems installed at open-hearth shops operating with oxygen lances.
