"The volatile matter content of coal varies widely for the four main coal ranks and is low for high rank coals such as anthracite and higher for increasingly low rank coals. The higher the volatile matter content the more reactive a coal is which means it can be more readily converted to gas while producing less char.

Fly ash is the fine ash that is collected from coalburned flue gas, which is the main solid waste ...
The casting or foundry process melts the metal to a molten state, and finally pour the molten metal into a prepared mould to form a casting. Crucible furnaces are equipment used in the foundry industry for melting metals to cast metal products; such as machines, machine parts and other related engineering materials (see Fig. 4).
metal casting industry is implementing the Industries of the Future strategy and transforming metal casting processes. The CMC comprises the three leading technical societies representing over 80 percent of the industry: American Foundry Society, North American Die Casting Association, and Steel Founders' Society of America.
If you have information to add to this entry, please contact the Site Historian . The Canton Foundry Machine Co. was in business by 1907. By 1911 they were making a wide range of products, including some of interest to us: sheet metal machinery, drop presses, power hammers, shears, and grinders. The company survived until at least 1929.
UNITIV PRODUCTION COST ESTIMATION COST ESTIMATION IN FOUNDRY SHOP: Foundry is a metal casting process in which the metal is melted and poured into the moulds to get the components in desired shape and size. Castings are obtained from a foundry shop. Generally a foundry shop has the following sections : 1.
Sand casting involves four basic steps: assemble the sand mold, pour liquid metal into the mold, allow the metal to cool, then break away the sand and remove the casting. Of course, the process is more complex than it sounds. The first step of mold assembly is to partially fill the drag with sand.

Green sand is an aggregate of sand, bentonite clay, pulverized coal and principle use is in making molds for metal largest portion of the aggregate is a sand, usually silica or sometimes olivine. There are many recipes for the proportion of clay, but they all strike different balances between moldability, surface finish, and ability of the hot molten metal to degas.
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.
