Induction Coil

Induction Coil

CX-INDUCTION manufactures a full range of coil sizes and types for induction melting and heating applications. All new coils are custom designed and engineered for the customer's specific production needs and application. High conductivity copper tubing with proper wall thickness is selected to maximize electrical efficiency.

induction coils are designed with the mechanical strength to withstand the severe conditions of a foundry environment. High dielectrical and high temperature insulating materials are used for all coils with special attention to the operating environment such as vacuum or air melt applications plus what power, voltage and frequency is being applied.

We have an excellent engineering team that can custom design your coil configuration to satisfy any unique high temperature application.

CX-INDUCTION heating coils can be designed specifically for high temperature graphite heating. These coils can be engineered and specially wound so that a tri-zone heating process occurs. The top and bottom sections will heat at a lower temperature than will the middle section.

We design each coil to maximize the efficiency of the your melting or heating process.

We repair and rebuild customer existing coils.

 

Since high amounts of electricity can generate a tremendous amount of heat, the entire system is water-cooled. The water travels through the induction system via the same route as the electricity. The water is recirculated throughout the induction system by a water pumping system and is cooled by a water cooling tower. The use of induction technology for heating and/or melting metal alloys is faster and more precise in temperature than traditional furnaces, which involve heating the metal through an external means like fire, and has more widespread uses in metallurgy.

 

remanufacturing/rebuilding induction coils

 

Cx-induction market niche in the induction equipment manufacturing industry is its product offering of remanufactured/rebuilt equipment. We offer customers the option of either rebuilding their existing induction equipment to "like new" status or purchasing all remanufactured/rebuilt equipment as opposed to buying brand new equipment.

 

Before the remanufacturing/rebuilding process begins, our sales and engineering departments review customer requirements for rebuilding their induction equipment or the equipment that is selected from a huge inventory of used equipment.

 

The rebuilding process includes completely stripping the equipment down to individual part and component level. New components and parts replace all old, damaged and obsolete parts. Exteriors are sandblasted, refabricated and then repainted. Equipment is then reassembled and sent to the testing department for thorough and complete testing for structural integrity and full functionality. The end result is equipment that looks and functions like new equipment.

Rigid Graphite Thermal Insulation

Rigid Graphite Thermal Insulation

Application:

Graphite rigid insulating boards in PAN rigidized felt or Rayon sliced foam are used insulation for vacuum & protective atmosphere process furnaces.

The boards are easily cut or machined to size to fit both square and round hot zones.

The boards can be machined into complex shapes and made to print in large sizes

Surfaces & cut edges can be sealed using our Graphite Coating.

Repairs and connections are made using one of our family of Graphite Adhesives.

Graphite foil added to the surface or layered in the board increases radiant heat retention significantly as wellas reduces issues with furnace contaminent containment 

Foil helps decrease pump down times and increase longevity of the insulation.

Similarly, CFC covering on the boards gives durability, impact & wear resistance.

Features:

Carbon Boards (1200ºC heat treated) are rigidized PAN long fiber felt.

Only Stocked in 60in x 40in x all thickness on Pricing sheet with foil on 2 sides. Raw and one sided carbon board has a 1-3 week lead time.

Graphite Boards (2000ºC heat treated) are shaved Rayon foam stocking in (60 x 40in) & (52 x 24in) size with foil on 1 side for shipping in 1 week.

Boards can be lined (covered) on one or both sides with;

Graphite foil (0.015 in. thick) = add $50 per side.

CFC (carbon-fiber-composite) (0.030 in. thick) = add $250 - $450 per side.

Board thickness capability up to 20 in. thick

High temperature heat treatment up to 2600°C & halogen purification available. Priced at time of quote.

Rigidized felt has courser fiber & so better for oxidation resistance & heat treating vacuum furnace or hot pressing applications.

Graphite Crucible


Product Description Our graphite crucible is made from selective raw material, and added into anti oxidation composition .It  has many advantages,widely used in melting Aluminum,Copper,Gold,Silver etc.
1. Thermal stability: according to the acute thermal and quench usage station of the graphite crucible,  special design is in order to promise the quality.
2. Corrosion resistance: the uniform and dense design can effectively weaken the corrosion of the crucible.
3. Impact resistance: The impact strength that graphite crucible can bear is very high, thus any further  process can be done easily.
4. Acid resistance: Special material is added into the crucible in order to improve the quality of the graphite crucible,     especially be effective in acid resistance ,and can greatly extend the life of graphite crucible
5. The high thermal conductivity: the high content of fixed carbon ensured the good thermal conductivity,  and shorten the time of dissolution, significantly reduce fuel consumption, or other energy  consumption.
6. Metal pollution control: the material composition is strictly controlled to keep the metal from being  polluted by the graphite crucible
7. Quality stability: High pressure forming method and quality assurance system fully ensure the stability  of quality.
