Product Description

Product Description

JUCOS HIGH-PURITY SILICA RAMMING MASS

The Professional Lining Solution for Coreless Induction Furnaces. Our Ramming Mass is engineered with 99%+ pure crystalline quartz and scientifically graded grain sizes to ensure maximum density, superior erosion resistance, and extended furnace life for steel and iron melting.

Features

High Purity: SiO2 content ≥ 99.1% with extremely low iron and alkali impurities.
Optimal Density: Scientifically distributed grain sizes (0-5mm) ensure a dense, void-free lining.
Superior Thermal Stability: Withstands temperatures up to 1750°C without cracking or spalling.
Excellent Corrosion Resistance: Protects the lining from slag erosion and chemical attack during prolonged melting.
Easy Sintering: Controlled boric acid/oxide addition ensures a stable sintering layer and long-lasting safety layer.

Applications

Steel Melting: Ideal for carbon steel, alloy steel, and high-manganese steel melting in induction furnaces.
Foundry Industry: Extensively used in iron melting for producing high-quality automotive and machinery castings.
Non-Ferrous Processing: Suitable for copper and copper-alloy melting furnace linings.
Kiln Furniture: High-temperature support and lining repair for specialized industrial kilns.

Q1: Is this material pre-mixed with binders?

A1: Yes, we provide pre-mixed silica ramming mass with boron oxide/boric acid for direct, hassle-free installation.

Q2: What is the maximum service temperature of the lining?

A2: Our high-purity ramming mass is rated for service temperatures up to 1750°C in coreless induction furnaces.

Q3: How do the grain sizes affect performance?

A3: A scientific ratio of coarse, medium, and fine particles (0.1mm - 5.0mm) ensures maximum compaction and erosion resistance.

Q4: Can this be used for melting stainless steel?

A4: While silica mass is standard for iron/steel, we offer specialized Magnesia-based ramming mass for specific stainless steel or alkaline slag conditions.
