Cast Steel Shot
Cast Steel Shot Use
1, the product characteristics
"Golden Link" brand cast steel shot is modeled on the United States "SAEEJ827" cast steel shot successfully developed a new technical standards for abrasive blasting, by-products for foundry, machinery, automobiles, airplanes and container manufacturing industries such as cleaning up all kinds of castings and forgings, steel plate The rust paint and metal workpieces mechanical parts of the surface hardening treatment, particularly suitable for high-speed, strength and big shot blasting machine equipment.
"Golden Link" brand cast steel shot with high-quality scrap as the main raw material, refining furnace, centrifugal forming, anti-rust treatment, heat treatment, screening and other elected park and grading procedures, strict quality control for production. Heat treatment is to produce high-quality Shot Guan Jian process. My company uses a pioneering medium temperature secondary quenching and tempering process, the complete elimination of the cast steel shot the original coarse organizations, to ensure Shot with a high strength, high toughness, high wear resistance with sex. "Golden Link" brand cast steel shot by several large enterprises in actual production use, service life of white iron pills 5 - 6 times, can improve productivity and 28.6% for the as-cast Tempering Shot in 2 - 3 times , use the "Golden Link" brand cast steel shot can significantly improve sub-pill round of shot blasting machine, orientation kits, leaf life span than the hands and white iron pills can increase blade life of nearly ten times, so that the working surface of the finish has improved significantly.
"Golden Link" brand cast steel shot through a nationwide technical evaluation of its process, quality in the domestic leading position, to catch up with international peers advanced level.
2, the main technical requirements
1, the chemical composition: C: 0.85 ~ 1.20%; Mn: 0.6 ~ 1.20% Si: 0.4 ~ 1.0%; SP <0.05%
2, hardness: cast steel shot into the pill must be re-quenched after the hardness should not be less than the HR60, tempering hardness should be 40-50.
3, microstructure: the final microstructure should be uniform tempered martensite, fine granular carbide should be uniformly distributed, mesh carbide is not greater than three.
4, density: the density of steel balls is greater than 7.25 grams / cubic centimeter.
5, roundness: cast steel shot shall be spherical or nearly spherical, long bar, (more than one-third of the diameter) and the mutual bonding of composite particles (bonded particle diameter of not more than one-third have been bonded in diameter) should be less 15%
6, crack: Crack and generosity in the radius of pills and no more than 15% of each inspection shall not be less than 20,
7, hollow: (1) The porosity should be less than 10% (2) Shrinkage rate should be less than 10% (shrinkage area of 40%).
3, particle size specifications and application range
3.0mm-3.6mm, 2.5mm-3.1mm: Casting and Forging for medium and large drop sand and surface cleaning and enhancement.
2.0mm-2.6mm, 1.5mm-2.1mm and practical in the small and medium sized castings and forgings, cast iron drop even sand and surface cleaning, heat treatment processes pieces of clean-up, steel rust to paint, the metal workpiece parts enhanced processing.
0.8mm-1.6mm, 0.3mm-0.9mm and practical for small castings and forgings, precision castings, nonferrous metal workpiece clean-up, steel plate, steel strip rust to paint, heat treatment, and forgings oxide clean-up.
