Melting Furnaces

Compact melting furnaces for the melting of non-ferrous metals and alloys are one of a kind and have anumber of technical advantages. Designed as tabletop models, they can be used for many laboratory applications. The practical counter balanced hinge with shock absorbers and the spout on the front of the furnace make exact dosing easy when pouring the melt. The furnaces are available for furnace chamber temperatures of 1200°C. However we have the capacity to customize the furnace temperature and sizes as per individual requirement. The heat is applied through microprocessor based controller. They are used to melt ironand steel, copper, aluminium and precious metals. The advantage of the compact furnace is a clean, energy-efficient and well-controllable melting process compared to most other means of metal melting. Since no arc or combustion is used, the temperature of the material is no higher than required to melt it; this can prevent loss of valuable alloying elements. By increasing temperature the alloy melts. And after the required time the lid is opened and the melted metal is poured for future use.

Vacuum Furnace

Vacuum resistance furnace is widely used in the heat treatment of metallic material in coarse vacuum, in reducibility or protective atmosphere. It Can also be used for special heat treatment of materials such as carbon products in the development process of carbonation. It can heat materials, typically metals, to very high temperatures and carry out processes such as brazing, sintering and heat treatmentwith high consistency and low contamination. In a vacuum furnace the product in the furnace is surrounded by a vacuum. The absence of air or other gases prevents heat transfer with the product through convection and removes a source of contamination. The Furnace are designed to meet temperature & vacuum atmosphere requirements.

Features:

Uniform temperatures in the range 1100–1500°C (2000–2800°F)
Low contamination of the product by carbon, oxygen and other gases
Quick cooling (quenching) of product.
The temperature control unit consists micro-processor based PID controller cum indicator. Benefits of using PID controller:
- Processing speed is high
- Provides flexibility to alter the system by changing software.
- Compact in size.
- Operation and maintenance easier.
- Maintain precise values
Over temperature limiter.
Programmable Vacuum automatically control the vacuum on/off according to the user-defined value of temperature (vacuum start & stop temperature) and time (vacuum holding time).
PCRC Sheet Body – Powder coated steel body assures corrosion resistant furnace and allows working of chamber at high temperature applications.
Digital Output – Target and Performance Output of the furnace operations are in digital format(digits) giving precise reading.
Precise Control of Environmental Parameters -The set/ programmable parameters of thefurnace are precise or have less deviation from original value,thus ensuring correct measurement.
Aesthetically Designed -Designed according to the standards and principles underlining industry’s aesthetic values.
Corrosion Resistant Interior and Exteriors -Corrosion resistant coatings like epoxy coatings are applied inside and outside the furnace to prevent against degradation due to moisture, salt spray, oxidation or exposure to a variety of environmental or industrial chemicals/ corrosive agents.
Sturdy Construction-furnaces are built with robustness to withstand stress and strain, giving it long life and ability to perform in extreme stress environments.
