High Efficiency 55kw Electric Vacuum Pit Type Furnace For Metal Heat Treatment

Pit Type Electric Resistance Tempering Furnace

1. Brief Introduction of pit type tempering furnace:
Heat treatment furnace is divided into annealing furnace, quenching furnace, tempering furnace, normalizing furnace, quenching and tempering furnace, carburizing furnace, nitriding furnace, melting furnace. Mainly used for high chromium, high manganese steel castings, ductile iron, roll, steel, stainless steel quenching, annealing, aging and a variety of mechanical parts heat treatment. Welding parts to eliminate stress annealing, aging and other heat treatment process. Heating methods are electric heating, fuel, gas, coal, hot air circulation and etc.
2. Structure of Pit Type Tempering Furnace:
Pit type furnace is mainly composed of furnace shell, lining, heating device and temperature control and other major parts, furnace body is cylindrical deep well, workpiece is installed vertically furnace inside for heating, Pit type furnace is usually placed under the ground plane in the workshop, also is placed above the ground plane, or ground level fluctuation in each half.
Pit type furnace can also be used for mechanical parts for tempering ,annealing, normalizing, carburizing and carbonitriding heat treatment, etc, electricity or gas can be used for heating, with electricity as heat source, is called the pit type resistance furnace,can form a complete set of heat treatment production line with pit type tempering furnace, quenching tank, washing machine and other equipment.

3. Application of pit type tempering furnace:

This pit type tempering furnace is mainly used for tempering of carbon steel materials mechanical parts after quenching.

Annealing Furance designs can be stationary, moving or continous, are a few examples. Annealing is applied to both ferrous and non-ferrous metals, and is intended to reduce the strength and hardness of the product while increasing the ductility.

The annealing process generally begins at an elevated temperature and may involve controlled slow-cooling or quenching depending on the material.

4. Main technical parameters of pit type tempering furnaces:

5.Package of Pit Type Resistance Furnace:

As for packaging: The resistence furnace is wrapped with plastic film for waterproof, and then put on the pallet.

As for shipping:

1. If you have shippers in China, we can send the machines to them for free.

2. If you want us to send the machines to you directly, we can send them to any main port of China promptly.

6. Advantage of pit furnace:

Full fiber pit type annealing furnace

The structure of this electric furnace includes furnace body, heating elements, furnace tank, cover, electric control system and etc..

Furnace body: Cylindrical shape. The frame and shell are made of welded steel.

Lining: The full fiber structure lining is part of insulation in chamber. It's made of the last new standard ceramic fiber blanket as the insulation material. Using a special equipment according to the size of the chamber to made the fiber into a folding block, and leaving a certain amount of compression between the folding block in the processing to ensure that each piece of ceramic fiber blocks expanded in different directions and squeezed into a gap-free when the folding block in the masonry is completed, to achieve a good heat storage effect. The anchor is arranged on the cold surface of the furnace body, which improves the high temperature strength of the fiber.

7. Instructions for use

This series of tempering furnace is the national standard energy-saving cycle operation furnace. Super energy-saving structure. Full-fiber structure, saving 30% to 40% energy. Adopting the exclusive production of high temperature heating components, anti-impact sealing brick on car, automatic sealing car and door, integrationit track, it is suitable for using in pressure vessel, die steel, alloy steel, special steel, high manganese steel liner, high chrome ball, low chrome ball, roll, flange, ductile iron, Steel structure welding stress and other metal materials for tempering, annealing, and various parts of the heat treatment of parts.
