Foundry burn on is the term for a wide ranging number of effects causing surface defects in the sand casting of metals, at high temperatures. Such defects require machining to remove them, adding time, cost and complexity to the process. Coal dust can be added to the sand in up to 5% by weight quantities to prevent the formation of defects.

Even surface finish: Using coal dust low ash in sand casting has proven to produce more even surfaces than Petrobond sand. This is because, with foundry coal dust, sand inclusion and expansion defects are eliminated. It produces whole, solid blocks such with no blow holes even when the crosssection of the cast object is analyzed.

It is recommended that foundry coal dust have a minimum of 30% volatile matter. Ash content: Coal dust low ash content, not exceeding 12% is recommended from coal dust suppliers. Sulfur content: A high sulfur content may lead to casting defects. Coal dust suppliers should limit the sulfur levels to 1% at most.

Sulphur content of foundry coal dust should never be more than 10%. Optimum levels of Coal Dust should be established by trial and always weighed and metered. Appropriate proportion by weight of Coal Dust in greensand varies from 2%3% for small castings and from 7%8% for heavy work. Higher levels are sometimes used in special cases.

Molding is a multistep process that will form a cast around the pattern using molding sand. In casting, a mold is contained in a frame called a flask. Green sand, or molding sand, is packed into the flask around the pattern. This is known as metal sand casting. Once the sand is packed tight, the pattern can be removed and the cast will remain.
