Abstract

1429710 Making beams; rolling; continuous casting MANNESMANN AG 11 Dec 1973 [19 Dec 1972] 57253/73 Headings B3A B3F and B3M A method of making a metal beam of H- section, comprising a web portion 1 and two flange portions 2 of substantially equal thickness, includes casting a first beam having the web and flange portions such that one of the portions is thicker than the other two, the other two portions being generally of equal crosssectional thickness cutting a length'from the first beam forming a recess 4 in one end face of the portion of greater :thickness, and forming the cut length into a second beam of the final required cross-section, the additional material in the thicker portion being accommodated in the recess to form a substantially flat end face. The first beam is continuously cast (using an immersed spout) with the web portion 1 of greater thickness then the flange portions 2 and the recess 4 prevents the formation of a tongue of scrap metal which would otherwise occur as the beam portions are rolled to final thickness. The beam lengths are cut by means of cutting torches or shears and the recess may be formed during the cutting operation.
