Pyroform HP™ Materials Rex Materials Group

With years of proven performance, Pyroform HP is the refractory material preferred by Wagstaff for use in their billet and rolling casting systems. Pyroform HP has significantly lower conductive heat losses compared to both fused silica and high density castable materials. Because Pyroform HP has an extremely low thermal mass, it also takes much less energy out of the metal at the start of the cast.

Lecture 2. Basics of MetalCasting Casting methods

Sand casting uses natural or synthetic sand (lake sand) which is mostly a refractory material called silica (SiO2). The sand grains must be small enough so that it can be packed densely; however, the grains must be large enough to allow gasses formed during the metal pouring to escape through the pores. Larger sized molds
