Product Description

Refractory Insulating Castable

Today, we are acknowledged in the market as one of the trusted manufacturers and exporters of Refractory Insulating Castable. These are perfect for making backup and hot face linings in different industries like cement, steel, metal processing, chemical and automotive. Our Refractory Insulating Castable is processed from top notch compounds at our state of the art manufacturing unit, as per the standards laid down by regulatory bodies. Our clients can avail these products from us at pocket friendly prices.

Features:

  • Low heat capacity and thermal conductivity
  • Appreciated for its precise composition, longer shelf life and pure quality
  • Offered in quality packaging to protect them from moisture and contamination
Our Heat Castable are formed in three grades, such as J R Heat-A, J R Heat-K and J R Heat-C. All these contain special high purity and high alumina refractory binder. Key properties of the castable, including data on strength, chemical composition & conductivity are provided in the table. All grades of J R Heat Castable are used for a particular environment and temperature.

JR Heat-A

J R Heat-A - A high purity and high alumina castable showing excellent quality with over 90% of alumina content and very low silica & iron content. Therefore, it is ideal for service temperatures upto 1750ºC, and can withstand attack from process gas atmosphere, containing hydrogen and carbon monoxide. 

J R Heat-A is suitable for use in coke oven gas production plants and gasification plants. It is also used in:
  • Iron & steel industry for blast furnaces lining, and for ports, skew backs and roof lining of arc-melting furnaces.
  • Non-ferrous metal industry for lining reverberatory furnaces, where high-purity aluminum is manufactured.
  • In refineries’ reactors and fertilizer plants where castable with a high level of resistance to carbon monoxide, ammonia and hydrogen are preferred. For lining of converters / preheaters and on any transfer line.
J R Heat-K

J R Heat-K has 60% alumina content, and can be used for service temperature upto 1600ºC. Also the castable has a low iron content and can withstand carbon monoxide attack. It is used in:
  • Blast furnaces
  • Boiler industry stoker arches
  • Foundries
  • Sites where reducing atmospheres are faced.
  • Construction of forge furnaces, tunnel kilns, soak pit covers and electro-phosphorus furnaces.
J R Heat-C

J R Heat-C is a castable with around 50% alumina, and it serves as a general-purpose high temperature castable ideal for service temperature upto 1500ºC. It is used in:
  • Iron & steel industry
  • Annealing furnaces
  • Stress relieving furnaces
  • Semi-permanent foundries
Construction of specific refractory shapes, ash-hopper linings, incinerator arches and monolithic convection units in water tube boilers.  

Packaging & Storage:

Our Heat castables are available in 50kg HDPE packages. The shelf life of the castable is 6-9 months under idyllic storage conditions.
