Annealing Furnace is a standard energy-saving periodic operation furnace with a super energy-saving structure. It adopts a full-fiber furnace chamber structure and saves 30% of electricity. Mainly used for quenching, annealing, aging for high chromium and high manganese steel castings, ductile iron, rolls, steel balls, 45 steel, stainless steel ,and doing heat treatment for various mechanical parts.
Annealing Furnace uses modules made of full-fiber aluminum silicate blankets to build the furnace body. The furnace bottom is built with lightweight insulation bricks and heavy refractory bricks. The heating elements are heated with resistance wires and resistance tapes. The furnace shell is made of steel plates and structural steel, and the furnace door and trolley adopt mechanical transmission. The specific equipment is designed and equipped according to the customer and furnace temperature requirements. Mainly suitable for heating in heat treatment workshops of steel mills, special steel, machining, chemical machinery, heavy industry, metallurgical forging, casting, forging, flange rings, steel components, wire drawing, environmental protection equipment, machinery supporting enterprises, loaders, diesel engines, military industry and others. It does not require foundation installation, can be used immediately after being placed on the level ground.
The annealing furnace can perform high-temperature heat treatment at 1200°C, medium-temperature heat treatment at 950°C, and low-temperature heat treatment at 650°C. Mainly used for mold annealing, annealing heat treatment of high chromium, high manganese steel castings, gray iron castings, rolls, steel balls, wear-resistant lining plates and other workpieces.
The furnace lining is made of high-aluminum fiber cotton. This material has strong high temperature resistance and good thermal insulation properties, and cannot be replaced by ordinary fiber cotton. The load-bearing part is built with heavy refractory bricks to enhance the structural strength of the furnace lining. In order to ensure that the temperature heat transfer at the bottom of the trolley is not very high, the trolley insulation layer uses a composite structure of aluminum silicate refractory fiber and diatomite insulation bricks to improve the thermal insulation performance of the furnace body. Adopting advanced hanging structure, the radiation efficiency is high, which strengthens the heat exchange in the furnace, improves the thermal efficiency of the furnace, and extends the service life of the electric heating element.
The electric heating element is made of 0Cr27AL7MO2 resistance tape, which is processed into a waveform structure using a special mold, and is hung in groups on the furnace wall fixings. It is very convenient to install and maintain, and has a long service life. The furnace body adopts a refractory full-fiber large plate structure and has excellent heat insulation properties. The weight of the full fiber furnace lining is only 1/30 of the refractory brick furnace body. It not only has excellent thermal insulation performance, but also saves about 30% of energy than the brick annealing furnace of the same specification and increases the heating speed.
The heating methods of annealing furnaces can be divided into three types: electric heating, fuel heating and gas heating.
According to different uses, annealing furnaces can be divided into: Trolley Annealing Furnace, Vacuum Annealing Furnace, Box Annealing Furnace, Pit Annealing Furnace, Heavy Pressure Vessel Annealing Furnace, Continuous Wire Annealing Furnace, Spheroidizing Annealing Furnace, Continuous Bright Annealing Furnace, etc...
Adopting advanced hanging structure, the radiation efficiency is high, which strengthens the heat exchange in the furnace, improves the thermal efficiency of the furnace, and extends the service life of the electric heating element. It adopts a composite high-aluminum porcelain nail set, anti-collision sealing bricks for the trolley, automatically seals the trolley and furnace door, and integrated rails without the need for basic installation.
Customized design according to the actual requirement of customers.
No noise, no environmental pollution, small heat storage and low heat loss. It has high temperature control accuracy, strong furnace temperature uniformity, high degree of automation and simple operation. It can be set by PID programming, fully automatic operation, good sealing, long life, safe and reliable.
It adopts low-nitrogen combustion technology and flue gas waste heat recovery technology, which greatly reduces the emission of harmful substances such as nitrogen oxides. Automated control technology enables precise control of furnace temperature, atmosphere and other process parameters, improving product quality and production efficiency. The protective gas in the furnace is circulated by strong convection by a special fan, and the furnace temperature is uniform, so that the temperature difference in the furnace is controlled within 5°C, thereby effectively ensuring that all annealing materials in the furnace are consistent in softness and hardness, and facilitating deep processing of materials.
Heating process:
By providing suitable heating method, the metal material is heated to a certain temperature. The purpose of heating is to eliminate stress and deformation within the material and improve its microstructure. Control of heating time and temperature is critical to achieving ideal material properties.Insulation process:
After being heated for a certain period of time, the material needs to be insulated to ensure a uniform temperature. The holding time depends on the type of material and handling requirements. Insulation can help rearrange the grains inside the material, further improving its mechanical properties and structure.Cooling process:
After insulation, the material will be gradually cooled. The control of the cooling process is very important. Cooling too fast or too slow may lead to inhomogeneity of the material, thus affecting the properties of the final material. Appropriate cooling rate can make the material obtain uniform grain size and structure, improve its strength and wear resistance.
