Aluminum Fluxes 101 - Basics of Furnace Cleaning, Dross Handling and Wall Cleaning

Read Full Article: EnglishSpanish

Casting defects, energy usage, metal recovery, ergonomics, and labor are cost variables addressed by properly identifying and applying fluxes for the aluminum casting operation. Proper selection and application are especially important to realize the benefits that flux can provide.

Defects stemming from the use of dirty metal are plentiful. Metallic aluminum is very reactive with atmospheric oxygen, and a thin passivation layer of aluminum oxide (4 nm thickness) forms on any exposed aluminum surface in a matter of hundreds of picoseconds to form aluminum oxide (Al2O3). Hydrogen forms whenever molten aluminum meets water vapor, and easily dissolves into the melt. The gas tends to come out of the solution and forms bubbles when the melt solidifies. The detrimental effects arising from the presence of an excess of dissolved hydrogen in aluminum are numerous. Aluminum oxide and hydrogen gas H2 are the two most common defects found in aluminum castings. Magnesium formation is also common in aluminum melting due to reaction with the alloy or with the refractory which typically contains magnesium and oxidizes rapidly forming magnesium aluminate (spinel), which visually forms black speck inclusions in the metal surface. Aluminum fluxes will address all three potential inclusions from the process of melting to final molten metal preparation. This article will cover two of the seven fluxes listed below*, drossing and wall cleaning fluxes, and some of the key savings.

casttherm molding

HA-International, in partnership with Rand York, is proud to introduce CastTherm Chromite to the North American foundry market.

Over the last decade, casting production has seen a dramatic increase in demand for intricate designs and shapes to meet everchanging customer needs. We've also seen increased issues with availability and escalating prices for ceramics and zircon materials.

The availability of multiple screen distribution CastTherm CR (or Chromite) sands offers a broader solution to meet this need head-on.

The Recommended Solution
In molding applications where high thermal conductivity, heat resistance, dimensional stability, and casting surface finish are critical, CastTherm Chromite is the recommended solution. These chromite sand distributions support the production of castings with various alloy applications because they create optimal surface finish under demanding conditions. The resulting screen distribution of the chromite sand influences many foundry applications, including the casting surface appearance, binder level requirements, and overall performance.

CastTherm CR foundry grade chromite is used for its:

  • Highest chilling properties of specialty sands
  • Excellent thermal conductivity
  • High sintering point
  • Low thermal expansion
  • Lowers cost-in use (reduced defects, cleaning room)
  • Range of available GFN distributions

Types of CastTherm
The CastTherm CR 45 product is the conventional material used by steel and gray iron foundries for mold and core production. CastTherm CR 60 and CastTherm CR 80 because of their finer GFN have a more comprehensive range of foundry and alloy applications than CastTherm CR 45 and offer a solution to other specialty sands. Chromite sand's chilling tendency at the mold metal interface, higher heat-transfer consideration, and refractory characteristics of the CastTherm CR 60 and 80 chromite sand can create an improved surface finish.

Cutting Edge Feeding Technology for Advanced Casting Processes

Read Full Article: EnglishSpanish

The use of exothermic and insulative feeding systems - sleeves and pouring cups - have been common practice for many years. Increasingly over the last three decades, foundries have improved productivity by increasing the number of castings per mold. This economical change has resulted in more restrictive positioning of the feeding sytems on the pattern plate.

This reduction in feeder size and contact area makes it challenging to maintain feeding performance. Advancements in manufactured feeding solutions continue to be developed to meet these challenges foundries face with balancing improved processes, productivity and costs while maintaining high quality castings.

5 Keys to Reducing Casting Defects Through Refractory Coatings

Read Full Article: EnglishSpanish

In an industry that has been around for many centuries with a wealth of knowledge and experience, we still today find ourselves when analyzing casting defects asking, "what changed?" This is because we understand that our industry is process dependent and controlling those processes is key to success. Refractory coatings are one of the products that we utilize to produce quality castings. Although usage is small in comparison, these products are applied at the mold/metal interface which is critical when it comes to defects. Crushes, inclusions, scabs, expansion, gas, metal penetration, misruns and rough surface defects can all be affected by refractory coating practices. Therefore, how do we control this aspect of our foundry operations?

Reducing Shrinkage in Aluminum Castings With Resin Selection

Read Full Article: EnglishSpanish

As casting geometries become thinner in design and more complex, the influences from resin selection will place a more crucial role in providing a solid casting. An aluminum foundry was experiencing issues with a dendritic type shrinkage defect that was related to a recent change in a resin package, resulting in higher scrap rates from the shrink defect.

The only variable that changed and created the dendritic type shrink defect in this case was the resin. HA-International designed an experiment to determine how PUCB resin percentages, and solvent packages used in urethane cold boxes affected the influence of shrink on this particular aluminum A316 casting during solidification.

Evaluation occurred on a newly developmental phenolic urethane cold box and a modified version of this new system, utilizing the latest solvent packages found in HAI's SigmaCure series of phenolic urethane cold box (PUCB). The experimental setup of the study included computer aided modeling, analytical testing, and actual casting tests to generate cooling curves. These results, in conjunction with the temperature dependent properties were used to create simulation model datasets for the cold box sand mix in order to simulate the actual sand mold physical properties and understand how it was creating the shrinkage defects. Between 1,500-2,000 design iterations were conducted in modeling software to obtain a dataset that matched the results from actual lab casting results. The specific heat capacity and density results required for the simulation datasets were measured directly using instrumentation on test molds.

Optimized Feeding Systems

HA SS_2019_S_EN

It is well known that metals change volume during solidification. This volume change must be compensated during solidification otherwise shrinkage defects can occur in a casting, making it unusable for its stated purpose.

This has been solved through the use of adding a metal reservoir commonly known as a "feeder" the purpose of which is to supply liquid metal to the casting as it cools and solidifies.

As this technology has developed and been improved, newer types of feeder materials have become available, including combinations of exothermic-insulating and highly exothermic compositions. The choice of material depends upon the application.

An Interesting Approach to the Product Installation Process


I always have believed that to successfully implement a new resin system in an existing or new customer, it is necessary to take into consideration four important factors: Materials, Methods, Manpower, and EH&S. The first three represent a three-sided equilateral triangle, which in turn is being supported by safe practices and products. If any of the sides of the triangle are unbalanced, the chances of carrying out a successful implementation could be compromised. Any substantial deficiency of any of the 3 M's (Materials, Methods, Manpower), will require that the other two be challenged at a higher degree.

Understanding 3D Sand Printers and Binder Technologies


AM for cores and molds is gaining popularity because of the flexibility and complexity it offers in production, but productivity is critical to the long-term prospects

Additive manufacturing of sand cores and molds has attracted the attention of many foundries in recent years due to the process' unique ability to form core shapes that cannot be manufactured using conventional coremaking techniques. It does this by a process called "binder jetting": a reactive resin, most commonly, a furfuryl alcohol-based (FA) binder formulated for the application is deposited on a substrate. Typically, the substrate is a silica sand that has been pretreated with an acid catalyst, but it can be a number of other aggregates used in metalcasting, such as zircon and synthetic ceramics.
