What is the riser? What does it do? What kinds are there? Below, and Anaijie furnace lining material manufacturers to understand it!

Riser refers to the supplementary part attached to the top or side of the casting to avoid defects. In the mold, the cavity of the riser is a cavity for storing liquid metal, and the metal is supplied when the casting is formed, which has the effect of preventing shrinkage, shrinkage, exhaust and slag collection, and the main role of the riser is shrinkage.

Design of different functions of the riser, its form, size and opening position are different.

Type:

1, ordinary riser: the riser made of ordinary modeling materials is called ordinary riser;

2, thermal insulation riser: the riser made of thermal insulation material is called thermal insulation riser, and the metal liquid in the thermal insulation riser has a longer solidification time than the ordinary riser, saving metal;

3. Heating riser: Adding heating agent to the riser material, after pouring metal liquid, the heating agent reacts and heats up, so that the metal liquid can remain in the liquid state for a longer time, saving metal than the thermal riser.
