Gas Stove Burners Made in Dandong Foundry
Gas stove burners
are used on the gas stoves or furnaces for
residential and industrial usage. Usually, the gas
stove burners are made by gray iron class 25, 30,
35, or called grey iron. Gray cast iron has enough
strength and has good
resistance to deformation. In addtion, its cost will
be lower than ductile iron, and has better
flowability of liquid iron.
As for the casting process, we suggest to use the
hot resin sand core and green sand shell. When I
said hot resin sand, I meant the
hot precoated sand or called ZFS, which
is a kind of yellow sand mixed by the sand and
resin. Please check our
Hot Shell or
Core Casting Process for the details for ZFS
process. The ZFS sand garantee the good inside
surfaces. The inside surfaces of burners are complex
and difficult to be cleaned. Other casting process
can not meet the requirements. However, for the
industrial stoves, the green sand casting process
can meet the surface requirements for surface
quality. Of course, sometimes, you can choose to use
ZFS sand for the shell too, if you are will ing to
pay for the extra costs or has very high surface
requirements.
As for the quality
inspection, the suggest to allow some few sand holes
and air holes which have diameter 2mm with max.
depth 1mm. If you require higher than this standard,
you should use the hot shell process.
