不銹鋼精密鑄造技術存在的問題如下：
The problems of stainless steel precision casting technology are as follows:
1.環境污染嚴重、作業環境惡劣
Serious environmental pollution and harsh working environment
鑄造生產中爐料主要是生鐵、廢鋼、焦炭、石灰石等、型砂、芯砂。主要是原砂、粘土、煤粉、樹脂等粘結劑、固化劑、舊砂等的運輸、混砂、造型、制芯、烘烤、熔化、澆注、冷卻、落砂、清理和后處理等工序。
The main furnace materials used in foundry production are pig iron, scrap steel, coke, limestone, molding sand, and core sand. It mainly involves the transportation, sand mixing, molding, core making, baking, melting, pouring, cooling, sand dropping, cleaning, and post treatment of raw sand, clay, pulverized coal, resin, and other adhesives, curing agents, and used sand.
2.工藝水平低，鑄件質量差
2. Low process level and poor casting quality
澆注系統設計不合理。由于設計不當，存在卷氣、夾雜等缺陷，導致鑄件出品率和合格率低。
The design of the gating system is unreasonable. Due to improper design, defects such as air entrainment and inclusions exist, resulting in low yield and qualification rates of castings.
3.能耗和原材料消耗高
High energy consumption and raw material consumption
