Ceramic fiber Blanket is Composed of selected flexible and long fibers made by the "spun" and “blown" process. The fiber blanket has excellent strength, lightweight and durable for application. working temperature range from 950 °C (1700 °F) to 1450 °C( 2600 °F). Fiber blanket has strong heat resistance with excellent insulation value
|
 |
|
Ceramic fiber boardis lightweight refractory and insulation materials which produced through wet forming process whit organic and inorganic binder . Working temperature range from 950 °C (1700 °F) to 1450 °C( 2600°F). Fiberboards ideal insulation materials for furnace , kiln door and duct with lower thermal conductivity and low heat storage.
|
 |
|
Ceramic fiber bulk is made by the melted raw materials at high temperature through resistance furnace, before being blown or spun into fiber. As a neutral and acidic material, except reaction with the strong acid-alkali, ceramic fiber won't be eroded by other weak alkali, weak acids, or water, oil, steam, or be infiltrated with lead, aluminum or copper, featuring excellent flexibility and elasticity.
|
 |
|
Ceramic fiber paper is composed of selected high purity Alumina silica fiber and made through fiber washing process. Working temperature range from 1200°C (2192°F) to 1450 °C( 2600°F). Fiber paper has very low slag content and very low organic binder during process. Light weight, low shrinkage and excellent strength.

 |
|
■ Switch
Temperature Switches have bimetal contacts with a range of different setting and contact functions. Either one or two contacts are inserted in to a housing made of brass or stainless steel.
|
 |
|
Temperature gauges are used to determine:
|
 |
|
■ Digital Temperature Indicator
،Temperature indicators provide continuous LED display of temperature in commercial building uses. Allows user selection of Fahrenheit or Celsius.
|
 |
|
This controller combines proportional control with two additional adjustments, which helps the unit automatically compensate for changes in the system.
|
 |
|
Profile Controller are mainly used for controlling temperature or any other process parameter against time. User can define the required time / temperature profile with the help of extensive instruction set like jump, loop,
|
 |
|
An on-off controller is the simplest form of temperature control device. The output from the device is either on or off, with no middle state.
|
 |
|
Ceramic fiber module use high-quality spun fiber blanket and continuous folded under compressed. As a new ideal refractory furnace lining products mainly aiming at simplifying and speeding up furnace construction and improving the integrity of furnace lining. It can be directly fixed with the anchor on steel plate for shell of industrial furnace with excellent refractory and insulating effect. Anchor system: 304 & 310 stainless steel.

|
IFBs (Insulating Fire Brick) are particularly Suited to applications above 1000 °C , where their thermal conductivity is as low as fiber based products , but with structural integrity Capable of dealing with erosive and abrasive environments.
|
 |
|
Board (Micro porous calcium silicate board) is a fiber reinforced calcium silicate board . Using silica , calcium oxide and reinforced fiber as raw material .As a ideal insulation material
|
 |
|
Vacuum formed Special shapes produced with high quality selected alumina silica fiber by vacuum forming technology. It is designed according to different base , surface treated and inserts, some shapes like pipe ,tap cone , cover etc are very common .Working temperature range from 950 °C (1700 °F) to 1450 °C(2600°F). This product is manufactured according to the specific needs and specific application of customers.

Fe Cr Al and Ni –Cr alloys are used in many different appliance. Most typical applications are as following.
|
 |
|
Molybdenum Disilicide(MoSi2 ) heating element is a resistance generate-heating component made from MoSi2 or the basic material .It is used in high temperature under the oxidizing atmosphere , it look like glass in its surface and form a light SiO2 glass film which can protect the element not to be oxidized .So this kind of element has unique effect for resisting oxidization in the high temperature . It is used to the highest temperature up to 1800 C during oxidizing atmosphere. According to you request , We can supply the products of Pole ,”U” , “W” and “U” – right angle shapes , etc.
|
 |
|
There are two main types of electric resistance alloys .Nickel chromium (Ni-Cr) alloy and ferritic iron –chromium –aluminum (Fe Cr Al) alloy. The two main types of alloys have their own specific properties with advantages and disadvantages, and are supplied in many different grades and forms.
|
 |
|
■ W-Type
This type of elements are self-bonded silicon carbide formed by re-crystallization of silicon carbide at high temperatures .It consists of three high – purity silicon carbide elements connected at are end by a silicon carbide crossbar .
|
 |
|
■ U-Type
This element consists of two silicon carbide legs with equal diameter each leg is divided into two parts, hot zone and cold zone with a joint. Resistance of both is equal to ensure a uniform performance. Both shanks are joined with crossbar made of low resistance.
|
 |
|
Similarly to single spiral type, this type of element is a tubular element with a spiral – grooved heating section, and as a major characteristic, both electrical connections are found at one end only. Installation of this element is very easy.
|
 |
|
Single spiral type element is manufactured with a spiral – grooved heating section which is made of homogeneous, high density silicon carbide crystals .It is more resistant to heat and corrosion then conventional products.
|
 |
|
Rod type of heating elements is used in applications ranging in temperature from 600˚C up to 1600˚C in both air and controlled atmosphere. This type of element may be mounted either vertically or horizontally. No special supports are required
