Measurement of casting shrinkage with U-type tungsten die

Casting Tungsten Carbide Powder is manufactured by melting Tungsten metal and Carbon together. It has two eutectic compositions: WC and W2C. The melt is cast through quenching into extremely hard solid particles of fine crystal structure. The tungsten casting technique is now sufficiently advanced to prepare hollow and solid billets. Generally, grain size is much smaller than that normally obtained in arc-melted ingots. Improved mold surfaces virtually eliminate mold contamination. A variety of processes can further work the resulting castings. The effect of tungsten on microstructure and high chromium cast iron properties was investigated. The experimental results indicated that tungsten was distributed uniformly in the matrix and carbides. W carbides are composed of WC1−x, CW3 and W2C. With the increase of tungsten content, bulk hardness and matrix microhardness increased gradually and reached a peak at 62.62HRC and 913HV, respectively. The most important item is a furnace that can reach temperatures above 6,100 degrees Fahrenheit—hot enough to melt tungsten. A high-temperature induction furnace is ideal for this purpose. You will also need an inert atmosphere, such as argon or nitrogen, protective gear like heat-resistant gloves, and a face shield.Tungsten is an extremely valuable metal because of its significant use in wear-resistant materials used primarily in the metalworking, mining and construction sectors. A simple method was developed to accurately measure casting shrinkage using a U-type tungsten die. A wax pattern was prepared on the die invested together in phosphate-bonded investment. But significantly decreased as the mold temperature raised to 600 degrees C.
