Scope

Scope: This standard specifies the grades, chemical compositions, and related technical requirements of silicon carbide used in casting melting, as well as testing methods, inspection rules, quality certificates, and transportation and storage requirements, etc. This standard applies to the addition of silicon carbide during the melting process of steel castings, gray iron castings, nodular cast iron castings, and vermicular cast iron castings, etc. Main technical content: The grades of silicon carbide used in casting melting are composed of the molecular formula "SiC" representing silicon carbide and a number representing the silicon carbide content. The chemical composition of silicon carbide used in casting melting shall comply with the provisions of Table 1. Table 1 - Grades and Chemical Compositions of Silicon Carbide Used in Casting Melting **Chemical Composition (%) SiC** **Free Carbon** **Free Silicon** **SiO2** **Al2O3** **Water** **Others (Fe2O3, CaO, MgO)** SiC90 88.0–92.0 ≤4.5 ≤4.5 ≤1.0 ≤0.5 ≤0.5 ≤1.0 SiC95 92.0–97.0 ≤2.5 ≤2.5 When the purchaser has special requirements for elements and contents, they shall be agreed upon by the supplier and the purchaser.
