Romac purchased the foundry in 1975 to produce castings for our line of pipe products. In 1995, we expanded on the five acre site, and modernized the entire facility. The modernization enabled the Romac foundry to produce castings fast and efficiently. With the new high speed, high capacity equipment, we entered the general foundry business.
Lowinflamation synthetic oils enable coolant temperatures to rise as high as 350°C (662°F). They allow for an initial heating of the whole mold and for a constant warming of cooler areas. Water, or an air/water mixture for coolant temperatures up to 160°C (320°F), is far more efficient for heat dissipation and more economical than oil ...
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.
A foundry is an industrial plant where metal is melted and cast into specific shapes by pouring it into a mold. The process itself is centuries old. Today, approximately 90% of all manufactured goods depend on metal castings for component parts, with cars and trucks being the largest market. Aluminum, iron, and steel are the most common alloys ...
The large variety of other casting processes and value added work performed at some casting facilities, however, makes it difficult to calculate the theoretical minimum requirements for the entire facility. Energy use also varies widely among facilities with differing sales volumes and dissimilar production castings for different end use

Tel.: 44 (0) 1234 758347. Email address: Abstract Casting is one of the oldest, most challenging and energy intensive manufacturing processes. A typical modern casting process contains six different stages, which are classified as melting, alloying, moulding, pouring, solidification and finishing respectively.
2. INTRODUCTION • There are large number of tools and equipments used in foundry shop for carrying out • different operations such as sand preparation, molding, melting, pouring and casting. They • can be broadly classified as hand tools, sand conditioning tool, flasks, power operated equipments, • metal melting equipments and fettling and finishing equipments.
The first foundry on soil was the Saugus Iron Works in Saugus, Massachusetts, which opened in 1645 and operated for 30 years. It's now a National Historic Site and museum. English ironmaster Abraham Darby changed metal casting forever in 1709 by using coke to fuel his foundry instead of standard coal. Coke is a porous material rich in ...
Most thermocouple types are useable to higher than 1200F. Kcouples (the most common off the shelf, included with many multimeters), for instance, top out at about 1350C (which is about 2400F)
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.
Foundry coke is also called hard coal coke, it is a highquality grade of coke. The process such as a beehive, formcoke, jumboovens, and byproduct recovery process are used in the manufacturing of foundry coke. The product is highly utilized for efficient cupolas for melting iron and other metals such as copper, lead, tin, and zinc at cupola ...
"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.
By combining these processes the foundry can save to per ton. The patented design has the lowest operating cost per ton in the global metalcasting industry. Foundries benefit in several ways, including less capital equipment to purchase, less floor space, much lower energy costs, less maintenance time and costs, lower shot ...

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.
There are five casting defects caused by heat, including hot tears, cold shut, and thermal fatigue. 1. Hot Tears. Hot tears are some of the significant casting abnormalities that occur due to heat. This defect occurs during the solidification of the metal casting.
Automatic bottom pouring is mainly used in investment casting industry. In this technique, a hole is created in the base of melting crucible to provide bottom pouring and was shielded by a cylindershaped shell of metals . In stir casting process, the matrix material is melted and maintained a certain temperature for 23 h in this furnace.
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.
