ML Furnaces Limited

ML Furnaces is a family business which has continued to grow in line with technology since the 1950s. It has developed a strong base in laboratories, engineering workshops and aerospace industries for heat treatment.

ML Furnaces offers a wide array of muffle, tube and chamber furnaces and ovens. They can come with or without air circulation. We specialise in electric furnaces, including a number of options ranging from 800°C to 1700°C.

An electric furnace provides the following benefits:

  • It is safer to use compared to a gas or oil alternative. There is no need to worry about oil and gas leaks or venting exhausted gases.
  • It generally has cheaper initial cost.
  • It is durable. It can withstand decades of use with proper maintenance.
  • It is easier to clean and maintain.
  • It provides an infinitely controllable system of heating .

We also offer ovens, furnaces and kilns that are suitable for low to high temperature applications. For all your oven and furnace requirements, please call ML Furnaces on 01623 835611 with your enquiries.

Products sorted by Maximum Temperature Capability

Ovens

Ovens are primarily used for warming, drying, and tempering. The maximum operating temperatures of ovens are from incubators at about 70°C to annealing ovens and tempering ovens with increasing temperatures up to 650°C maximum.

Types of Ovens

  • De-waxing oven

    With a stainless steel, sloping floor leading to a drain, this oven is designed to allow molten wax to be collected and later re-used.

  • Burn-out oven

    Designed to allow a good flow of air through the chamber in order to facilitate the combustion of any residue after de-waxing, the heated exhaust is provided to ensure that all waste gas is combusted efficiently.

  • Heat treatment oven

    Operating at a variety of temperatures up to 650°C with air circulation, anything above that temperature will usually eradicate the need for air circulation, which involves costly materials and is quite difficult to achieve.

Furnaces

A furnace is an industrial heating system that heats above 535°C (1000°F). Displaying similar features to an oven, the noticeable difference between ovens and furnaces is that furnaces have linings consisting of insulating and refractory materials. They are primarily used to heat metals and other materials using oil, gas or electricity.

Types of Furnaces

There are several types of furnaces, each varying according to its application.

  • Electric Furnaces

    These are furnaces that convert electricity to heat. They generate heat through the heating elements that are made-up of wound coils of resistive wires for mid-temperature range, and silicon carbide and molybdenum disilicide for higher temperatures. They are commonly located inside the electric furnace.

    Examples of Electric Furnaces
    • Ashing or combustion furnaces

      Usually wire wound, where the wire element is wound onto the outside of a dense, ceramic closed-end chamber, these furnaces normally operate at temperatures up to about 1100°C.

    • Induction furnaces

      They use the process of induction heating to heat metals, sometimes up to their melting point. They are ideal for use with metals with low melt-losses.

    • Crucible Furnaces

      Ideal for metal and glass applications, they are normally used by small foundry operators due to their low cost and usability.

Kilns

Kilns are usually used in pottery and ceramic applications. Fuelled by natural gas or electricity, they are typically used for drying and hardening clay, and glazes
