Anyang Hengsheng Metallurgical Refractories Co., Ltd.

China‑based Anyang Hengsheng Metallurgical Refractories Co., Ltd. lists twelve active products across the Silicon, Agriculture and Chemicals & Allied Products categories. The catalogue includes Silicon Metal Powder, various grades of ferro‑silicon (Fesi, Fesi 75, Ferro Silicon, Ferro Silicon Barium, Rare Earth Ferro Silicon, Calcium Silicon Manganese, Ferro Chrome Low Carbon, Ferro Silicon Zirconium Inoculant) and related inoculants such as Calcium Granules. Each entry is recorded without a specific HS‑code in the supplied data, but the product families map to standard HS chapters for silicon and ferro‑alloys. The supplier’s trust tier is listed as “harbor,” indicating a moderate level of verification within the platform. The product set reflects a focus on metallurgical additives used in steelmaking and alloy production.

The product portfolio covers both pure silicon forms and alloyed ferro‑silicon variants that are typical inputs for de‑oxidation, de‑carburisation and alloying in the steel industry. Silicon Metal Powder generally conforms to purity grades of 99.5 % Si or higher, while ferro‑silicon grades such as FeSi 75 contain roughly 75 % silicon and 25 % iron. Inoculants such as Calcium Granules and Ferro Silicon Zirconium Inoculant are supplied for alloy refinement and cast iron treatment. Although HS codes are not supplied, these items usually fall under HS 2602 (silicon) and HS 7202‑7204 (ferro‑alloys). The range suggests capability to serve downstream metallurgical processes that require precise silicon content and controlled impurity levels.

The catalogue presents a core set of ferro‑silicon products ranging from standard FeSi to specialised blends such as FeSi 75 Mg (Ferro Silicon Magnesium Nodulizer) and Rare Earth Ferro Silicon. In the global market, ferro‑silicon is typically graded by silicon content (e.g., FeSi 75, FeSi 65) and may include magnesium or calcium modifiers to improve fluidity and reduce slag formation. Silicon Metal Powder is commonly offered in 99.5 % or 99.9 % purity, with particle sizes from 10 µm to 200 µm depending on end‑use. Calcium‑based inoculants are measured by calcium oxide (CaO) content and are used in cast iron to promote graphite formation. Buyers usually request material safety data sheets (MSDS), purity certificates and, where relevant, compliance with ISO 9001 quality management systems.
