Cobalt nickel alloy spinner discs casting

The spinner discs  is a key component of the fiberizer. It is a metal disc with an arc-shaped side wall and thousands of small holes on its surface.
The spinner discs part rotates at high speed during use.
 Under the action of centrifugal force, the glass liquid is thrown to the edge of the centrifuge head, covering the entire arcuate surface, and is squeezed out of the small holes on the spinner discs  surface to form a glass fiber precursor.
Because the spinner discs is used at a high temperature of more than one thousand degrees, and the rotation speed is very high, and at the same time, it is also subjected to the corrosion of the glass liquid, so the requirements for the material of the centrifuge head are very high.
Stainless steel materials were used in the early days, but now they are all made of special cobalt nickel alloys. 
The aperture of the centrifugal head is specially designed, requiring the aperture size to meet the requirements, and to be round and uniform.
It is precisely because the glass fiber precursor must be formed through each small hole, so as long as it can be quickly stretched by the high-speed airflow, there will be no slag balls. 
This is why the slag ball content of centrifugal glass wool is very small, or even no slag ball at all.
The castings are made from our own patented materials cobalt base alloys or nickel base alloys,regular diameters ranges from OD200 to OD500mm, like diameters Φ300mm,Φ303mm,Φ320mm, Φ360mm,Φ380mm, Φ390mm, Φ400mm,Φ406mm etc.
Qingdao Hexin Machinery Co., Ltd. has the ability to smelt thousands of tons of special high-temperature alloys every year, has the ability of research and development, testing, and has the ability of spectrum analysis in front of the furnace. The centrifugal discs produced by our company are positioned at high-end quality and are mainly exported abroad. Compared with other products in the same industry, they have obvious quality advantages.
With reliable quality and sound reputation, our company has established long term supply relationships with many foreign glass wool companies.
Under this circumstance, our company decided to promote and introduce our spinner disks products to large glass wool production companies at home and abroad. 
Our company can process and manufacture according to your company's drawings. 
Please indicate the diameter and the number of holes when ordering. A quotation will be given according to the drawings and specifications.
