Cobalt Nickel Alloy Spinner Discs Casting For Glass Wool Defibering Machine
New Products From This Supplier
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.

HEXIN Machinery is focusing on the manufacturing, quality control, research and development of heat resistant stainless steel castings for the most demanding high temperature environment used for various industrial furnaces. HEXIN is aiming to be a world's reliable brand of centrifugal casting tubes, and static castings with high nickel chrome alloy materials, we always do our best for products and technology innovation , and long term customer relationships. We achieved great customer satisfaction by taking extra step to improve the castings quality and improve the bottom line of the customers. we believe that EACH DETAIL MATTERS, so we are working hard to improve our casting quality continuously. We have been working with the well known international engineering and furnace companies like Tenova LOI, Drever, Danieli, Fives Stein, CMI, Ipsen, Aichelin, Technip, CBI for different castings , like radiant tubes , furnace rollers, sink rolls, immersed and stabilizing rolls , heat treatment fixtures like basket, tray, rack, grid, fans , catalyst tube, reforming pipe, tube sheets, tube support hangers , furnace hooks, and more. we are confident that we could guarantee the quality of our tubes and castings. Our radiant tubes, furnace rollers, skid riders, walking beams and other static casting furnace replacement components have been well known and approved by our customers for reliable quality. We supply them to most of the famous furnace makers and engineering companies, like LOI, Danieli, Drever, and more, for their projects in and outside China. Our investment casting and static casting workshop is focusing on the production of HEAT RESISTANT materials with high nickel , chrome, cobalt, like HK, HT, HP, 1.4848, 1.4849, 1.4852, 2.4879. We mainly produce castings for heat treatment furnace fixtures and petrochemical fired heaters, like casting baskets, trays, grids, fans, beams, brackets, tube sheets, tube supports, furnace hooks, Y pieces, elbows, manifolds, and more. Our reforming tubes and cracker tubes are produced by the advanced centrifugal casting machines with technology from Europe. Equipped with 12 sets of horizontal centrifugal casting machines by advanced technology, the patented design of moulds, to guarantee the mould spins faster but steady, so that the poured tubes with more compact inside quality, with longer unit length of the tube. To gain the better quality of spun casting tubes, we have long term technology and commercial communication with famous companies like Technip, CBI, Uhde, Forster wheeler. Our lift out rolls, lehr rolls , plain and pattern engraved main rolls, table rollers have been installed in over 290 glass production lines worldwide. Since 2009 , we started the production of our own brand rolling machinery for cast glass, now we cover more than 60% of the market in china for patterned rolling glass plants. We welcome the customers and friends home and abroad to visit us, for technology or commercial cooperation. Welcome aboard, and let's grow together.
