Allied Mineral Products Opens New China Plant
Refractory manufacturer to supply customers in Asian markets

Assessing Monolithic Refractories
The right insulation for aluminum melting-holding furnaces should reflect actual operating conditions, which may include higher heat levels as a result of efforts to increase productivity.

Think Globally, Supply Locally
The merger of Süd-Chemie AG’s and Ashland Inc.’s foundry chemicals businesses late last year established a new commercial presence in metalcasting. ASK Chemicals CEO Stefan Sommer addresses the new company’s objectives and opportunities.

Advances in Riser Design Improve Steel Casting Quality
Material selection can impact metal chemistry

Zinc Slag Resistance Proven for Refractory Lining
An alumina-bonded silicon carbide can be formed into intricate and precise shapes, and resists oxidation and thermal shock.

CastExpo ‘10 Preview
A week in the sun never sounded so good. For metalcasters enduring weak demand and idle production, the fresh ideas and technical insights upcoming at CastExpo will seem even more welcome than a few days of warm weather and relaxation.

Molten Metal Splash and Furnace Refractory Safety (part 2)
A sound refractory that has been properly installed, sintered and maintained, plus operator diligence to prevent a dangerous bridge from forming, are key to minimizing metal run-out. (The second of two parts.)

Molten Metal Splash and Furnace Refractory Safety
Molten metal splash is the most common cause of melt deck injuries and is caused by the addition of wet materials to the molten bath. It can be minimized by diligently inspecting and treating scrap. Metal run-out ranks among the most severe accidents that can occur during melting and holding. First of two parts.

Energy-saving Innovations for Furnaces, Delivery Vessels
Tests show an increase in the melting capacity of gas-fired reverb furnaces using a dry hearth.

Coatings Go Beyond Appearance to Provide Quality Control
Refractory coatings help foundries to protect bonded-sand cores and molds from producing defective castings, such as products with metal...

Gas Diffusers Improve Induction Melting
For many years, gas diffusers, also known as porous plugs, have been used in ladles to allow gas purging of steel melts before pouring the...

New-Concept Lining for Faster, Simpler Replacement in Induction Melters
Faster induction furnace turnaround during system relines, and the ability to make repairs more easily to particular areas in between relines,...

Vibration Improves Installation for Channel Furnace Inductors
Installing dry vibratable refractory to optimal rammed density involves installing the material to a prescribed thickness, deairing it,...

Research Results in Better, Longer-Lasting Refractories
A two-pronged effort set out to prolong the service life riser tubes, and to improve their performance in aluminum casting.

Refractories: Pre-Cast Product Speeds Holding Furnace Relines
System eliminates water from installation process

Pre-Cast Product Speeds Relines for Diecasters’ Holding Furnaces
“… a system that will eliminate water from the installation process …”

Considering Refractories
Often overlooked, refractories are possibly the most integral part of a foundry — impacting energy consumption and overall operations.

Shaking Up the Process of Installing Refractories
The process can be faster and easier, more consistent, and less expensive.

Finding Faults
When it’s time to choose a brick or refractory material, it’s critical to determine what caused the prior installation to fail. Here are several tips for understanding how ash and slag affect the insulating material.
