Heat Treatment Furnace: An Essential Tool for Every Workshop

A heat treatment furnace is an essential tool for many industries where hardening of various metals is required. The hardening process aims to increase the hardness and strength of the material, which allows for better mechanical properties and resistance to wear. Thanks to heat treatment furnaces, this process can be carried out in a controlled and precise manner, ensuring uniform quality of the products.

Welded Construction

The heat treatment furnace is equipped with heating panels that are replaceable in case of damage; the replacement can be done without dismantling the insulation. The frame of the furnace is a solid welded structure that ensures resistance to the conditions in which the furnace operates. It provides stability and protection against mechanical damage, which results in longer service life and reduces operational costs.

The furnace is equipped with high-quality heating elements made from Kanthal A-1 wire. The structure of the furnace is based on a steel, welded frame that is resistant to high temperatures. The simplicity of the design makes the furnace very easy to operate. When choosing a furnace, it is important to pay attention to the heating elements, as they play a key role in the furnace’s performance.

In Elektrocast furnaces, the heating element is removable in case of damage. Another important feature is the use of resistance wire. We use only Kanthal A-1 wire from a renowned manufacturer. This wire has high thermal resistance (up to 1400°C), maintaining almost constant resistance at this temperature, which is why it performs so well in devices where the temperature is truly high.

Who Needs a Heat Treatment Furnace?

Knifemaking – A heat treatment furnace is an essential tool in the production of knives, playing a key role in shaping and improving the quality of these precision tools.
Motorsport –Hardening various components, such as crankshafts, pistons, valves, and flywheels, is crucial for improving engine performance, power, and durability.
Jewelry Industry – The production of jewelry items such as rings, chains, or bracelets, which may need hardening to increase their hardness and resistance to damage
Medical Industry – The production of surgical instruments, orthopedic implants, or dental tools that require hardening to ensure hygiene, durability, and safety.
Metalworking Industry – The production of various structural elements, gears, or machine parts that need hardening to increase their strength and durability.
Garden tool Manufacturers – The production of garden tools like shears, pruners, or saws that require hardening to ensure the durability and sharpness of the cutting edges.
Agricultural Industry – The production of agricultural tools, machine parts, and equipment for soil processing that must be hardened to ensure durability and performance in harsh working conditions.

And many other manufacturers.

What heat treatment processes can be performed in our furnaces?

Annealing – This process is designed to reduce internal stresses in the material, soften it, and improve its plasticity, as well as change its mechanical properties.
Tempering – A thermal treatment process aimed at reducing hardness and eliminating excessive internal stresses in materials that have undergone prior hardening or plastic deformation.
Metal melting – Our furnaces can also be used for melting various metals with the use of the appropriate crucible. Chamber furnaces have lower melting capacity, so we recommend checking our crucible furnaces for this purpose.

Setting the desired temperature in our furnaces is very simple. In the video below, you will find instructions on how to perform this operation. The PID temperature controller REX C100 ensures quick and reliable furnace operation. We use solid-state relays (SSR) instead of contactors in our furnaces, which brings several advantages, including quieter operation and longer service life.

Basic Furnace Specifications:

Insulating Material

We use high-quality insulating materials, such as ceramic fiber, which ensure excellent protection against heat loss. Our multi-layer insulation not only ensures optimal internal conditions in the furnace but also minimizes external temperature, contributing to the safe and stable operation of the device. The furnace chamber is made of impregnated ceramic plates resistant to working conditions.

Heating Element

The heating element in our furnaces is a spiral made from high-quality Kanthal A-1 resistance wire. This material is known for its durability, high resistance to high temperatures, and excellent heating properties. The heating spirals are precisely placed in replaceable fireproof plates, ensuring even heat distribution and efficient heating of the chamber.

Temperature Control

The PID type temperature controller allows you to set the desired temperature and includes continuous operation functionality. The temperature setting accuracy is 1°C. Temperature sensor: K-type thermocouple.

Additional Options:

Temperature controller with step programming option.

The process can be programmed in any way by the user. Each step consists of three settings: set temperature, ramp-up time, and holding time at the set temperature.

Reinforced Floor

Made from silicon carbide (SiC), this solution is recommended for heavy loads that may damage the furnace floor. Silicon carbide is an extremely hard material (9.5 on the Mohs scale), making it resistant to scratching, wear, and mechanical damage. SiC can operate at temperatures up to 1600°C.
