Sand Casting | Metal Casting Resources

Pure sand breaks apart easily, but molding sand contains bonding material that increases its ability to resist heat and hold shape. Green sand (an aggregate of sand, pulverized coal, bentonite clay, and water) has traditionally been used in sand casting, however modern chemically bonded molding systems are becoming more popular.

Cheap Fire Bricks For Sale From RS Group Refractory Company

Shaped refractory materials generally refer to refractory bricks, which have standard rules in shape, and can be temporarily processed during construction as required. Fire block is mainly used in lining furnaces, kilns, fireboxes, fireplaces and high heat equipments because its shape is similar to ordinary construction brick. RS Fire brick for sale is built primarily to withstand high

Foundry & Sand Casting Terminology ~ Metal casting projects

Green sand is coined of very fine sand such as silica, olivine or even play sand mixed with bentonite clay and water. There are many recipes that can be found on the internet for the different types and quantities and mixing ratio. Adding to much water can lead to "porosity", casting defects as result of gas bubbles accouring while pouring the molten metal. Some metal casters use blow

Refractories: Properties and Types | Engineering

Basic refractories consists mainly of basic oxides without free silica and resist the action of bases. The most common basic refractories are Magnesite, Dolomite, lime etc. But lime, because of its dehydrating tendency is never used as a refractory. Magnesite: This is most important basic refractory material.

Homemade furnace refractories - backyard. Metalcasting

The refractory mix is composed of Portland cement (1.5 parts), silica sand (2 parts), perlite (1.5 parts) and fireclay (2 parts). The first three components are mixed together thoroughly. I used a 1-gallon bucket to measure the parts. Less than one bag of perlite was necessary for the bucket furnace and I had about a gallon and a quarter of refractory left over. Tip: Build the body for a

3. Basic Materials For Construction

If you have to use these materials, you should wash the sand well. 4. Natural sand deposits can sometimes be found not too far from the construction site, for example in stream beds, dried-up lake or stream areas or quarries, but well-graded sands seldom occur naturally. In many cases, you will have to sift the sand through a 0.2 mm mesh screen to eliminate the finest particles. If there are

Green Sand: An Introduction to Its Use in Foundries

Coal dust, or anthracite, is fast becoming a common additive in the green sand moulding process. It is a carbonaceous additive that under foundry conditions cousts and oxidises. Historically, the leading additive in green sand casting, as a carbonaceous material, was highly volatile bituminous coal, often referred to as sea coal. Bituminous coal cousts in the mould upon heating and releases hazardous pollutants such as benzene, xylene and toluene. It is imperative that bituminous coal …
