Boron nitride nozzle has good thermal shock resistance,low coefficient thermal expansion and excellent chemical stability.It can be machined into complex shapes and will not contaminate molten metals.
DMCERA®Boron Nitride Nozzle
Amorphous alloy is a new type of energy-saving material.It is produced as thin strips or ribbons directly from the hot molten metal through rapid solidification process.Amorphous strips have high permeability and low loss at high frequency. Amorphous strip nozzle is a very important part in production.It affects production cost and strip quality.
Boron nitride nozzle has good thermal shock resistance,low coefficient thermal expansion and excellent chemical stability.It can be machined into complex shapes and will not contaminate molten metasl.Compared with pure boron nitride, boron nitride composite ceramics has better corrosion and erosion resistance and longer service life.At the same time, production costs will be reduced.
DMCERA supply amorphous strip and nanocrystalline ribbon nozzles.During strip spraying process, no deformation of the nozzle,no increase in nozzle slit and sprayed strips are uniform.
