Rice Husk Ash Thermal Insulation for Steelmaking is supplied as unground ash derived from rice‑husk residues. The material contains high carbon content exceeding 40 % and amorphous silica (SiO₂) as the dominant mineral phase. It is packed in bulk bags suitable for large‑scale handling. The supplier states the ash is sourced from major rice‑producing regions in Vietnam.
In the steelmaking sector the ash functions as a refractory‑grade thermal barrier because its low thermal conductivity reduces heat loss. Typical unground RHA particles are below 150 µm, giving a bulk density around 0.12‑0.15 g cm⁻³ (typical). The amorphous silica content usually falls between 45‑55 % (typical) and contributes to pozzolanic activity. Industry standards often reference ASTM C618 for pozzolanic materials, which the ash can satisfy (standard).
Steel producers and metallurgical furnaces purchase this insulation to improve energy efficiency and protect crucibles. The product is offered in bulk‑bag shipments, with incoterms and payment terms to be agreed with the supplier. Buyers should confirm minimum order quantities, packaging weight and any required certification before placing an order.

Rice Husk Ash is an agricultural byproduct with high amorphous silica content, widely used as thermal insulation in the steelmaking and metallurgical industries. With carbon content exceeding 40%, this unground ash provides excellent heat-resistant properties and is also used as a pozzolanic additive in construction materials. Sourced primarily from major rice-producing regions, it is exported in bulk bags and offers a cost-effective alternative to conventional insulating materials for high-temperature industrial applications.

Before placing an order, request a Certificate of Analysis that confirms carbon content, silica percentage, moisture level and bulk density. Verify that the ash meets any industry standards required for your furnace design, such as ASTM C618, and ask for test reports from an accredited laboratory.
Discuss logistics early: confirm the exact weight of each bulk bag, the total volume of the shipment, and the preferred Incoterm. Payment terms, such as a letter of credit or advance payment, should be agreed upon in writing to avoid misunderstand‑ings during the transaction.
Arrange for a third‑party inspection at the loading port if possible, and request documentation covering the test results, material safety data sheet and any export certifications. These steps help ensure that the ash arrives in the condition required for high‑temperature steelmaking applications.
