    摘要: Methods and apparatus for joining conveyed steel pieces in a hot rolling mill are disclosed. A joining apparatus having a series of fusing torches (6) extending laterally across the steel path is used, either before a rough rolling stage or between rough rolling and finish rolling. The fusing torches (6) which operate at the side edges of the pieces to be joined are controlled to have independent movement by a controller (37), in such a way that the time elapsing between fusing and pressing together of portions at the lateral edges of the join line does not exceed a critical time for regrowth of oxide scale. Various mounting and control techniques for the fusing torches (6) are proposed, including the possibility of two independently-driveable sets (8,8a) the controller can base its control of the torches (6) on steel strip width information obtained from the processing path.

    摘要: The present invention relates to a process for the staining of wood, which comprises treating the unstained wood with an aqeous preparation comprising a) at least one dye, and b) at least one dye stabilizer of the formulae (I) or (II) in which G1 and G2, independently of one another, are C1-C4 alkyl or together are pentamethylene, Z1 and Z2 are methyl, or Z1 and Z2 form a bridging member which is unsubstituted or substituted by an ester, ether, hydroxyl, oxo, cyanohydrin, amido, amino, carboxyl or urethane radical, E is oxyl or hydroxyl, and X is an inorganic or organic anion, and the total number of cations h corresponds to the total number of anions j, to a wood stain comprising a dye and a dye stabilizer of the formula (I) or (II), and to the use of this wood stain for the staining of wood.

    摘要: The present invention is a welded high-strength steel structure having a TS of not less than 900 MPa and excellent low-temperature toughness and a method of manufacturing the steel structure. The base steel is formed of a mixed structure of martensite and lower bainite and has a TS of not less than 900 MPa, and the weld metal is steel which has the following elements based on % by weight: C: 0.01% to 0,15%; Si: 0.02% to 0.6%; Mn: 0.6% to 3%; A1: 0.004% to 0.08%; Ti: 0.003% to 0.03%; O (oxygen): not greater than 0.06%; B: 0.0002% to 0.00%; and as optional components, Cu, Ni, Cr, Mo, V, and Nb and which satisfies the following two equations: 0.25 ≦ Pcm ≦ 0.32 and 0.6 ≦ Al/O (oxygen) ≦ 1.4.

    摘要: Die Erfindung betrifft einen Mehrflammenbrenner (10) mit Brennerköpfen (1), die dafür eingerichtet sind, bei Speisung mit einem Brennstoff wenigstens eine jeweils entlang einer Flammenachse (14) ausgerichtete Brennerflamme (13) zu erzeugen, wobei die Flammenachsen (14) jeweils nebeneinander angeordneter Brennerköpfe (1) schräg zueinander ausgerichtet sind. Ein Verfahren zum Vorwärmen eines Werkstücks, insbesondere eines Rohrs oder Großrohrs, ist ebenfalls Gegenstand der Erfindung.
