Description
Technical field:
The invention belongs to metallurgy and casting technology fields, and in particular to a kind of raising Electro Slag Remelting Steel Solidification Quality reduction element is inclined
The device and method of analysis.
Background technique:
In recent years, equipment manufacture level in China's is continuously improved, and extremely manufacturing becomes a prominent skill of equipment manufacture
Art development trend, one of them is towards super large direction and develops, the equipment enlargement of the fields such as electric power, petrochemical industry, metallurgy, complication pair
Heavy casting and forging industry proposes requirements at the higher level.Following a period of time will be that China promotes industrialized critical period, electric power, stone
The industries such as change, metallurgy, ship, aviation will all continue fast development, breed the Unprecedented demands to heavy casting and forging among these.
Significantly supply falls short of demand for heavy casting and forging in the world at present, and the heavy casting and forgings manufacturing enterprise such as JSW, bucket mountain heavy industry is all
It is full production, this proposes new challenge to the development of China's equipment manufacture in recent years, by external heavy casting and forging,
At high price, the delivery cycle is long, and crucial moment, the external technology blockage to China, and limits outlet, therefore greatly develop
The high-quality heavy casting and forging of China's proprietary technology, is of great significance.
Electroslag remelting process since its equipment requirement is low, and have the advantage that simultaneously pure metal, dense structure, at
Divide uniform, any surface finish, while with excellent product performance, the stability of technique and the reproducibility of quality are high, and produce
Flexibly, various ingot shapes can be produced.Electroslag remelting process is there are two important feature, it may be assumed that the continuity of electroslag metallurgy with it is stackable
Property, electroslag remelting can be by replacement consutrode continuous production, and can pass through multiple devices one large size of continuous production simultaneously

Ingredient multiplicity, especially alloying element or carbon element content is higher, since the solubility of these elements is in liquid and solid steel
Difference leads to that selective freezing has occurred when ingot solidification, it is uneven (segregation) to cause steel ingot internal component, and with steel ingot
Increase and the extension of setting time, this component segregation just more seriously, control the bad ingot casting report for possibly even causing to produce
Useless, this certainly will will affect the economic benefit of steel mill.Therefore, a large amount of research has been carried out for the control of large-scale casting ingot component segregation.
In the existing production technology of large-scale casting ingot, due to using protective gas as protective gas or not using argon gas,
Molten steel after solidification, due to volume contraction, can form one layer of air gap, when air or argon gas enter gas between crystallizer and steel ingot
After gap, since its capacity of heat transmission is poor, cooling water can be reduced to the cooling effect of ingot casting, extend the cooling time of ingot casting, from
And make ingot composition segregation aggravation, influence the Solidification Quality of Electro Slag Remelting Steel.Therefore, the equipment of appropriate adjustment electroslag remelting, in air gap
The stronger gas of the middle filling capacity of heat transmission very must for preferably playing the effect of electroslag remelting in the production process of steel ingots
It wants.
