What is a heat riser? Below, take a look at the small edition of Anaijie furnace lining materials sales company!

The heating riser is a supplementary part attached to the top or side of the casting to avoid defects in the casting, and its feeding effect is much higher than that of the floating bead thermal insulation riser, and the heating riser casting is dense without defects, which fully meets the basic technical requirements of explosion hardening. At the same time, the excellent density, that is, the internal quality, provides a strong guarantee for improving the wear resistance of the casting and extending the service life of the frog.

The heating riser is made by adding a certain amount of thermite, flux, oxidant and the above thermal insulation material when making the riser. Heat and heat preservation function.

When casting, the riser is rapidly ignited and burned at about 680℃, and the heat released at this time increases the temperature of the iron liquid in the riser, which makes the solidification time of the metal liquid in the riser longer, prolongates the feeding time, and improves the feeding efficiency of the riser on the casting.

The thermal insulation riser is mainly made of sand, drift beads, fly ash, refractory fiber cotton (suction filter riser) and other thermal insulation materials. Pure insulation can not heat. The purpose is to slow down the solidification time of hot metal in riser sleeve and improve the feeding efficiency.
