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:How many kinds of industrial electric furnaces are there?
Electric furnace is divided into four categories: resistance furnace, induction furnace, arc furnace and special electric furnace according to the different ways of electric heating.
Q:What is the difference between industrial furnaces and boilers?
A boiler is a mechanical device for heating water into hot water or steam by the use of heat from fuel or other sources of energy. The original meaning of a pot is a water container heated by fire. The furnace is the place where the fuel is burned. The boiler includes two parts, the cooker and the furnace.
Q:What are the advantages of a vacuum furnace?
No pollution to the environment, no need for three wastes treatment.
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 are the companies in the world that are currently engaged in metallurgical furnaces?
Each manufacturer has its own industry and technological advantages.If you say that the performance rankings, turnover, and so on, it seems that no one has done this ranking.
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:What are the combustion equipments used in industrial boilers?
Main auxiliary equipment for general boilers:1. domestic appliances 2. civilian gas boiler 3. industrial gas furnace.
Q:Brief introduction to repair of industrial furnace
The working condition of industrial furnace is very bad. It is affected by high temperature, slag erosion and burden wear. Therefore, its working condition changes quickly and its service life is short.
Q:Should the industrial furnace shell cool down?
If the furnace shell temperature is too high, it shows that the lining is not good or damaged, so it should be repaired in time. If you do not repair, take the cooling way, undesirable. Because this will cause a lot of heat loss, resulting in waste of energy, increase production costs, and affect the service life of the furnace.
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.
