Background technology
Casting heat energy-saving position easily produces shrinkage cavity or shrinkage defect, in order to eliminate shrinkage cavity or shrinkage porosite, technique typically can be adopted
With chill or rising head.
Chill mostly adopts metal chill, material selection HT200 or HT250 etc., and a small amount of enterprise selects graphite chilling block.Metal
Chill is larger due to its deadweight, and density is molding sand more than 4 times, so limited by its position of putting, be placed in foundry goods side or
Top surface may drop and cause to subside, thus causing scrapping of foundry goods；Have simultaneously access times limit, in addition using before to clear up beat
Mill weldering is dry, rustless no greasy dirt no dampness.This increased difficulty to production management.
Graphite chilling block does not then have the disadvantages mentioned above of metal chill.But the low intensity of graphite chilling block, cracky during knockout, from
And reduce service life, increase use cost.That generally the abrasion of big graphite chilling block is severe and that major part cannot use
Little graphite chilling block can only be discarded, and causes to waste.In order that these damaged graphite chilling blocks can recycle, we trial-produce successfully
Graphite sand chill.
Graphite sand chill is these discarded graphite chilling blocks to be processed into graphite particle mix with silica sand.Graphite sand chill is easy
In molding, various complicated shapes can be made；For some cast(ing) surfaces need place chill and execute-in-place is inconvenient to use gold
Belong to the place of chill, directly made using graphite sand and use as chill.Having of graphite can fully be inherited by graphite sand chill
Light specific gravity, refractoriness is high, the advantages of heat conductivity is big, can play chill effect and solve transportation problem.
