Abstract
กระบวนการหล่อโลหะผสมทองขาวกลุ่มแพลเลเดียมปราศจากนิกเกิล 18 กะรัต ประกอบด้วย 2 ขั้นตอน ขั้นตอนแรกเป็นการหลอมโลหะผสมทองขาว จากวัตถุดิบที่เป็นธาตุบริสุทธิ์และ/หรือโลหะผสมด้วย เปลวพลาสมาที่มีอุณหภูมิสูง ภายใต้บรรยากาศที่ควบคุมในระบบสุญญากาศ มีแก๊สอาร์กอนปกคลุม เพื่อให้ เนื้อโลหะเข้ากันดี และป้องกันการเกิดปฏิกิริยาออกซิเดชัน ขั้นตอนที่สองเป็นการหล่อขึ้นรูปเครื่องประดับ ดำเนินการโดยใส่อินกอตตามปริมาณที่ด้องการในเบ้าหลอม ใช้เตาอินดักชันแบบสุญญากาศ ให้ความร้อนใน การหลอมเหลวโลหะผสม ก่อนผลักดันให้ไหลลงไปในแม่พิมพ์เพื่อให้ได้รูปร่างชิ้นงานตามต้องการ The 18 karat nickel-free palladium group of platinum alloy casting process consists of two steps. The first step is the melting of the platinum alloy. From raw materials that are pure elements and / or alloys as well High temperature plasma flame Under a controlled atmosphere in a vacuum system Covered with argon gas to make the metal mix well. And prevent oxidation The second step is jewelry casting. Processed with the required quantity of ingots in the crucible. Use a vacuum induction furnace Heat in Melting of alloys Before pushing it to flow into the mold to get the desired shape
