Preheating Continuous Feeding system


AE series preheating continuous feeding equipment is the most advanced, clean, energy saving and environmental protection metallurgy off gas using equipment in nowadays. This is using the off gas from the electric furnace to preheat the raw materials, and avoided the high failure rate, complicated operation, can not charging materials continuously and etc weakness from Shaft furnace preheating and preheating bucket and etc traditional ways. This system has been put into production in more than 20 factories in china and several other countries. And had gain marked affects in electricity saving, energy saving, production increasing, pollution reduction, and brings great economic benefits for customers.

AE series preheating continuous feeding equipment has characteristics of continuous feeding, continuous melting, continuous smelting and etc… which advantages are: short smelting period, low power consumption, low noises, low investment cost and etc…
Compared with the traditional EAF, the technical index of continuously preheating and feeding EAF process are:

1. Production capacity increases more than 10%.

2. Smelting cycle is shortened by 10-15 Min.

3. Save energy of 100-120kw.h/t for per ton Steel.

4. Electrode consumption decreases by 0.5-0.8%, Refractory material consumption reduces by 5%.

5. 20-30% reduction of CO2 volume which is released from per ton of Steel; Production site dustiness less than 10mg/M3.

6. Dioxin and CO emissions meets relative emission standards, smoke and dust is decreased from 17kg/t to 11kg/t.

7. Fully utilization of waste heat: On the Conveyor section can preheat the materials up to 300 degree Celsius and higher, and add burner in conveyor section, can raise the materials up to 600 degree Celsius. The rear part of the waste heat can be used to generate electricity or heating by steam which is produced by waste heat boiler, the gas from the boiler basically can go into the bag type dust collector directly. But the traditional electric furnace system off gas must go through the water cooled pipes, air forced cooler and etc equipments, it will consumable much energy to cool the temperature down and then can put the gas go into dust collector, so waste the energy from the off gas.

8. De-duster Fan power reduces 30%.

9. Noise is less than 90 decibels during the electric furnace smelting cycle.

With fully considering for customers kinds of actual using status, AE series preheating continuous feeding equipment brings direct economic benefits to customers by lowest failure rate, highest energy saving index, biggest investment return.

Q:Heat treatment equipment (industrial furnace), which products generally contain what kind of, which industries need to use heat treatment industrial furnace equipment.
The general metal die casting plant and the metal smelting plant need process melting and dissolving furnace, usually there are reverberatory furnace, cupola, rotary furnace, etc. I do the melting furnace of aluminium alloy.
Q:What's the role of anchor bricks in industrial furnaces?
The wall of an industrial furnace or flue is mainly composed of an inner lining layer, a heat insulating layer and an outer wall layer. The lining is a refractory brick, and the outer wall is an ordinary sintered brick.
Q:What are the companies in the world that are currently engaged in metallurgical furnaces?
There are many kinds of furnaces in metallurgical industry,colored and black,smelting and heat treatment are also included.
Q:What is the difference between industrial furnaces and boilers?
Hot water or steam generated in the boiler can directly provide necessary energy for industrial production and people's life, but also by the steam power device is converted to mechanical energy, or through the generator converts mechanical energy into electrical energy. Hot water boilers are called hot water boilers. They are mainly used in daily life, and are also used in industrial production. Steam generating boilers are called steam boilers, often referred to as boilers. They are used in thermal power stations, ships, locomotives and industrial and mining enterprises.
Q:What is industrial furnace masonry?
Before masonry construction, the pre process and parts that may affect the quality of masonry work shall be re tested,masonry construction shall be carried out according to the datum central line and the datum elevation.
Q:Why does the burner of industrial furnace burn occasionally?
The basic structure of the complete ignition system is the ignition device and flameout protection device. The ignition burner includes an ignition electrode and an igniter (equipped with some external type transformer, voltage transformer) through the above 10kV, the ignition electrode spark ignition of high voltage discharge to ignite gas column.
Q:What is an industrial furnace pit?
The creation and development of industrial kilns play an important role in the progress of mankind. Chinese appeared more perfect in the Shang Dynasty copper smelting furnace, furnace temperature is up to 1200 DEG C, up to 0.8 meters in diameter kiln stove.
Q:What are the combustion equipments used in industrial boilers?
The boiler is an energy conversion equipment. The energy input to the boiler has the chemical energy and the electric energy in the fuel. The boiler outputs steam with certain heat energy and high temperature water.
Q:Brief introduction to repair of industrial furnace
Although the number of industrial furnaces in general machinery plants is not large, the number of large repairs per year accounts for 16%-20% of the total number of repairs for all equipment, and the large repair costs account for about 18%-25% of the total repair cost of all equipment.
Q:How to use industrial furnace equipment?
If it is water cooling furnace door, but also to ensure the smooth flow of pipes, winter pipes are not frozen. When the boiler is in a limited position, the interlocking device for cutting off the power supply shall be provided when the furnace is in and out, and the number of broken wires in the pitch of the steel wire shall not exceed 10%, and the counterweight of the furnace door shall be reliably hung.
