Definitions

  • integral and composite molds there are integral and composite molds.
  • The, composite molds are composed of plates whereas the integral molds consist of a prismatic or cylindnical tube.
  • the cooling arrangement there are molds formed with cooling bores, and other surrounded by a water jacket.
  • the wall thickness there are thin-walled molds,..the wall thickness of which is only sufficient for the mechanical stresses to be expected which differ with the shape and sizeof the cross-section;
  • Suitable alloying additions to the copper include mainly chromium, silicon, silver and beryllium. The amount of each of these materials should suitably not exceed 3%.
  • Such alloys known per se consist preferably of l-2% Cr, with or without O.ll% Si, balance copper and impurities which are inevitable in the manufacturing process.
  • the precipitation-hardening treatment of these known alloys with, e.g.,' 1.5% Cr is effected by a solution annealing at about 1000 C. followed by quenching in water and reheating for one to four hours at temperatures between 350 and 600 0., preferably by reheatingfor two 7 hours at 400C.
  • the precipitation-hardening treatment is suitably effected after the welding operation.
  • Molds according to the invention may consist partly or entirely of precipitation-hardened copper alloys.
  • Integral molds which are in most cases subject to very lugh stresses, consist in condition ready for installation preferably entirely of a precipitation-hardened copper alloy owing to the simpler manufacture.
  • the durability of a mold for continuous casting is essential for its usefulness.
  • the durability may be expressed r this reason, the molds employed in existing continuous
  • the high thermal" loading of the mold for continuous casting results in high stresses being set up in the mold wall as a result of thermal expansion, In continuous operati-on, these stresses result in deformation, which adversely affects the contact between the skin of the billet and the mold and consequently reduce the dissipation of heat.
