Silica Ramming Mass supplied by Sri Venkateswara Minerals is an acidic refractory aggregate with a silica content of 98-99 % SiO₂. The product is offered in two grades: ordinary silica ramming mass (OSRM) without binder and pre-mixed silica ramming mass (Pre-mixed SRM) that includes a proprietary binder. Both grades melt at approximately 3274 °F (1800 °C) and can withstand a maximum operating temperature of 1720 °C in induction furnace linings. Grain size is specified at 5 mm, providing a consistent texture for coreless furnace applications.
The ordinary grade relies on high-purity quartz and quartzite, while the pre-mixed variant adds a heat-stable binder to improve cohesion during installation. Impurity levels are tightly controlled, with iron oxide (Fe₂O₃) limited to 0.05 % and boric acid reported as nil, matching typical industry limits for acidic ramming masses. Such composition delivers excellent thermal shock resistance and corrosion stability at the elevated temperatures encountered in steelmaking. These characteristics align with standard refractory performance criteria used by secondary steel producers worldwide.
Typical buyers include steel mills and foundries that line coreless induction furnaces for scrap melting. Sri Venkateswara Minerals ships the material in standard 50 kg HDPE bags or in 1-1.25 tonne jumbo bags with internal liners, and can accommodate custom packaging on request. The listing does not disclose a minimum order quantity, so importers should confirm the required MOQ directly with the supplier. Payment terms, Incoterms and lead times are negotiated per transaction and should be clarified before contract finalisation.

Before placing an order with Sri Venkateswara Minerals, importers should obtain a recent assay report confirming the 98-99 % SiO₂ content and the stated impurity limits for Fe₂O₃ and boric acid. Request a material safety data sheet and, if possible, a sample for laboratory verification. Verifying the supplier’s harbor-tier status and confirming the correct company address in Visakhapatnam helps reduce the risk of mis-identification.
Shipping is typically arranged in 50 kg HDPE bags or 1-1.25 tonne jumbo bags with liners, allowing flexible freight consolidation. The supplier does not publish a fixed lead time, so buyers must negotiate the expected dispatch schedule and agree on Incoterms such as FOB Visakhapatnam or CIF Mumbai. Payment terms are usually discussed per contract; common arrangements include a 30 % advance letter of credit with the balance payable against documents.
Upon arrival, importers should arrange third-party inspection to verify grain size, bulk density and the absence of foreign matter, referencing the supplier’s assay and the typical bulk density of 1.5 t/m³. A certificate of conformity confirming compliance with refractory standards should accompany the shipment. Retaining the packing list, test reports and inspection certificates facilitates customs clearance and provides a record for quality assurance in downstream furnace lining processes.
