摘要
PURPOSE: A CuNi 90/10 flange and a method using free forging for manufacturing the same are provided to enable to form a regular alignment structure without heat-processing CuNi. CONSTITUTION: A method using free forging for manufacturing a CuNi 90/10 flange comprises; a step(S10) for preparing a continuous casting bar of a diameter of 6-10 inches; a step(S20) for cutting the continuous casting bar into 5-10 inches in a longitudinal direction; a step(S30) for heating the cut casting bar at a temperature of 900-950C for 150-300 minutes; a step(S40) for upsetting-forging the heated casting bar; a step(S50) for cogging the casting bar; a step(S60) for upsetting-forging the casting bar again after cogging; and a step(S70) for forming a flange shape by forging the casting rod. [Reference numerals] (S10) Preparing a casting bar material for 6-10 inches; (S20) Cutting a casting bar; (S30) Heating the casting bar(900-950C/30min); (S70) Generating a flange through die forging; (S80) Hole processing(Drilling or Punching)
