WHAT IS ROLLER HEARTH FURNACE ?

Roller Hearth Furnace is a industrial furnace where stacked things are heated in a protected car that is turned out of the furnace on rollers or chutes, guided by rails or a grooved way. A crane is utilized to load and empty things for handling on the car, or roller hearth. Sand or water are utilized to seal holes between the roller hearth and the dividers so as to diminish the admission of air into the furnace.


Ordered by their method of activity, roller-hearth furnaces have a place with the class of chamber furnaces. Roller-hearth furnaces are from 1.2 m to 6.4 m wide and from 2.5 m to 40 m long. They are warmed by gas or fluid energizes, utilizing burners or spouts connected along the length of the dividers in a couple of columns at the tallness of the furnace. Roller- hearth furnaces work at working temperatures extending from 500°C to 1150°C. They are utilized to heat treat things before fashioning or rolling.


ROLLER HEARTH FURNACE FOR CARBON STEEL TUBES AND BARS

Pipes, bars and other semi-completed products produced using carbon and low alloyed steel, including wire coils, are ending up progressively significant all through industry. Roller hearth furnace plants can be utilized to treat a wide scope of products which are utilized in every single industrial division. Practical, vitality proficient heat treatment plants are basic to meet the developing prerequisites looked by materials, for example, weight decrease without relinquishing quality and different properties in the vehicle business, and to deliver enormous amounts of materials required all through the world.


The heat treatment is a basic stage in the generation and handling of pipes and banishes produced using carbon and low alloyed steel. This heat treatment is chiefly done in roller hearth furnaces, which may either be electrically heated or gas-fired. The fundamental heat treatment forms under defensive gas air in a roller hearth furnace plant are bright annealing in mix with


• Stress relief
• Re-crystallization
• Normalizing
• Tempering
• Spheroidizing
• Solution Annealing
• Subcritical Annealing
• Isothermal Annealing


Roller hearth furnace plants with a defensive controlled environment are utilized to forestall undesirable responses, for example, the oxidation or nitrification of the charge material in air or waste gas and along these lines accomplish the most elevated prerequisites. Different elements of our controlled air plants, particularly for the treatment of carbon and low alloyed steel, incorporate the production of lessening conditions and additionally carbon action (the carburization or decarburization of the surface layer).


The controlled airs comprise of unbiased or latent constituents. Nonetheless, they may contain receptive parts for procedure reasons.The nonpartisan or latent segment is for the most part nitrogen. The dynamic or receptive parts are predominantly carbon monoxide mixes in which hydrogen is a basic component.


• Low utility consumption per tonne processed
• Maximum heating up rate
• Damage- free transport through the facility
• Minimum temperature difference at end of soaking time
• Shortest overall facility length
• Highest possible cooling gradients
• Heavy-duty design for a long service life
• Prevention of distortion during quenching
• Easy to maintain
• Lowest emissions
• Quiet operation

The roller furnaces are ordinarily utilized for high temperature treatments of substantial parts in contrast with work belt conveyor furnaces, seeing that the last have a constrained yield moment that it boils down to overwhelming burdens and high temperatures. Another favorable position of the roller furnaces is that they give extraordinary vitality investment funds since there is no transport to be warmed. The rollers are ordinarily made of artistic material which have extraordinary mechanical opposition at working temperatures and constrained redirection. Roller furnaces are chiefly utilized in the metal powder sintering sector, in quick steel treatments, in solution heat-treatment of stainless steel stamped objects, for example, sinks, food containers, basins, saucepans, and so on.
