Description
Technical field
The present invention relates to smelting equipment technical field, vertical shaft scrap steel preheating system is referred to more particularly, to a kind of swinging support.
Background technology
Steel is the maximum structural material and yield highest functional material of mankind's consumption, and steel industry is the pillar of China
Industry.With the rapid growth of steel usage amount, the generation of steel scrap is also in sustainable growth situation.Steel scrap can be obtained in converter
A certain amount of digestion, and most steel scrap needs to be handled in electric furnace.Electric arc furnaces is the height produced using electrode arc
Temperature carrys out the electric furnace of melting ore and metal, compared to converter producing, electric arc furnaces have high energy consumption, duration of heat length, production kind by
Limit, the shortcomings of production cost is high.If electric arc furnaces can be improved to enter the initial temperature of stove steel scrap will to greatly save cost higher
Power consumption, shortens the heat simultaneously, is improved the production capacity of electric arc furnaces.Therefore, there is scrap steel preheating technology energy-conservation to drop
The significance of consumption.

Bonding index arm makes the accident that steel scrap can not normally fall, and the unexpected slump of steel scrap also occurs and the accident of broken Electrode is pounded so that be raw
Production is not sufficiently stable.Moreover, shaft furnace electric furnace process equipment is different from common electric furnace, common electric furnace can not be served as in production and is used, cost
It is higher, produce dumb.Double type electric furnace is that another stove utilizes its waste gas to scrap steel preheating while a stove is smelted, and is given up
Steel temperature can reach 500 degree, but the investment of twin furnace shell direct current electric arc furnace is big, and floor space is big, and the utilization rate of electric furnace is low, and preheating
That electric furnace can only also preheat the first batch furnace charge of the electric furnace.Continuous charging electric arc furnaces principal mode is CONSTEEL electricity
Stove, such a waste steel for electric furnace preheating temperature is low, and mean temperature is only 200 degree or so, and electric furnace exhaust gas utilization rate is low, waste gas environmental protection

Body of heater is combined together, and influence factor is more in process of construction, and larger transformation need to be carried out to electric furnace, and construction period length simultaneously influences
Production.In order to make full use of high-temperature flue gas to preheat steel scrap, also need to carry out the sealing of bell and set up fume extractor, invest
It is larger.
Separate type scrap steel preheating system pre-heating device is separated with electric furnace body, is preheated and is separated with fusing smelting, is easy to tissue
Production, scrap steel preheating amount and heating-up temperature are easily controlled, the utilization rate in outer energy supply source is high, capacity utilization is high, can be given full play to
Capacity of equipment, it can respectively build, not influence the production of former electric furnace, and scrap build small investment, instant effect.However, separate type is useless
Steel pre-heating system can not utilize the high-temperature flue gas of electric furnace, and complete outer heat supply can be preheated to steel scrap, then will be useless after heating
Steel carries out fusing smelting in electric furnace using electric energy, so energy-saving effect decreases compared with monolithic construction.
