DETAIL CASTING USING SECONDARY METALS IN FOUNDRY ACCORDING TO GOOST MARKINGS

This article studies the scientific and technological aspects of casting parts in accordance with GOST standards using secondary metals in foundry. During the study, the influence of the chemical composition, alloying elements and heat treatment of secondary metals on the quality and mechanical properties of the part was analyzed. In experimental work, samples made from steel and iron alloys were tested for compliance with GOST standards. The results showed that the use of secondary metals reduces production costs and extends the service life of the part. At the same time, quality and reliability can be ensured through material optimization and control of casting technology本文围绕铸造厂依据GOST标准(GOST)、采用再生金属（secondary metals）生产铸造零件的科技层面问题展开研究。研究过程中，本团队分析了再生金属的化学成分、合金元素及热处理工艺对铸造零件质量与力学性能的影响。实验阶段，研究人员对钢铁合金制备的试样按GOST标准开展了合规性检测。研究结果显示，采用再生金属能够降低生产成本，同时延长铸造零件的服役寿命。与此同时，通过材料优化与铸造工艺管控，可保障零件的质量与可靠性。
