Foundry technology involves molding, melting, and casting of parts that is, producing castings by filling the prepared molds with molten metal alloys mostly aluminum. This is a unique primary metal processing method which must be imparted to most engineering students. The practical work enables the students to gain expertise and confidence in foundry activities.

universal sand testing machine with Compression shackles, weighing pan, measuring jar, steel scale, Electronic weighing scale. Theory 1. Periodic tests are necessary to check the quality of foundry sand and compression strength test is one amongthem. 2. The constituents of moulding sand are silica sand, clay, water and other specialadditives. 3.
Chrome sand is a major component in refractory bricks that are used in the foundry industry to line furnaces, fireplaces, kilns, ovens, and other high-heat environments. The bricks must be able to withstand temperatures over 1700 C, have excellent thermal shock resistance, and have both acid and basic slag erosion resistance.
In a sand casting foundry it is critical to maintain the consistency of AFS-GFN American Foundry Association Grain Fineness Number. Great care goes into designing equipment to prevent and eliminate sand segregation. Sand is an abrasive product so there

1. Screen analysis screen distribution and AFS grain fineness number About 90 of a mold is sand, so the base sand screen distribution is very important. In . most iron foundry green sand systems, the ideal screen distribution would be a four screen sand at least 10 or more on four adjacent sieves, with a minimum of 10.0 on the 140 ...
It is now more usual to refer to sieve size by aperture. However, the AFS number relates to and is calculated using the old BS mesh system, and effectively gives an indication of the sand type relative to the BS mesh size. See also Introduction to Section 3.2. AFS numbers are frequently used to denote the relative grading or grade of sand supplied.
