Description
Technical field
The invention belongs to field of metallurgy, relate to a kind of strand pouring technology, what tool was stopped says is the mixing pouring technology of different section strand in a kind of same group.
Background technology
Current iron and steel form is increasingly sharpened, and it is few that most iron and steel enterprise faces order, orders the situation of quantity not sufficient, and the same section order of normal appearance is few, cannot organize the phenomenon of production.Existing electric furnace factory conticaster is generally five machine five streams, and two cold water distributions are carried out secondary and automatically controlled, and discharge can change size according to pulling rate and automatically regulate, and prerequisite is same section; And in same group different section mixing cast secondary automatically to control water distribution be irrealizable, one-level must be adopted to control.
In order to adapt to market conditions as early as possible, expanding occupation rate of market and promoting heating cord product benefit, solving same section order few, the phenomenon of production cannot be organized, need to develop a kind of mixing pouring technology adopting different section strand in a group.
Summary of the invention
Technical problem to be solved by this invention is:
How to realize the mixing cast of different section strand in same group, and can ensure that the performance of strand does not decline and even increase.
In order to solve above technical problem, the application proposes the mixing pouring technology of different section strand in a kind of same group, has not only adapted to market conditions, and has expanded occupation rate of market, improves product benefit.
The technical scheme that the present invention solves above technical problem is:
The mixing pouring technology of different section strand in a kind of same group, the conticaster used is five machine five streams, it is characterized in that: 2 streams of described conticaster adopt 150*220mm sections, 1,4 and 5 streams adopt 150*150mm sections (3 streams can according to yield production 150*150mm or 150*220mm section);
Wherein, the crystallizer discharge of 2 stream 150*220mm sections is 2000 ± 20L/min, two cold specific waters are 0.77-0.79L/Kg, vibration parameters is: amplitude 3.75, frequency 190, M-EMS(M-EMS) electric current be 300 ± 5A, F-EMS electric current is 150 ± 5A, red base pressure is 25 ± 1Kg;
1, the crystallizer discharge of 4 and 5 stream 150*150mm sections is 2000 ± 20L/min, two cold specific waters are 0.57-0.59L/Kg, vibration parameters is: amplitude 4.5, frequency 117, M-EMS(M-EMS) electric current is 250 ± 5A, F-EMS electric current is 150 ± 5A, and red base pressure is 35 ± 1Kg.
The invention has the beneficial effects as follows: the present invention adopts one-level to control two cold water distribution patterns, the water distribution numerical value of setting and actual amount of water are all within technological requirement scope, blank steady quality, the deliver the goods of little order steel grade, not only save production cost, and adaptation market conditions, expand occupation rate of market and improve product benefit.
The present invention controls to be that 2000 ± 20L/min and two cold specific waters control as 0.77-0.79L/Kg by the crystallizer discharge of 2 stream 150*220mm sections, control to be 2000 ± 20L/min by the crystallizer discharge of 1,4 and 5 stream 150*150mm sections, two cold specific waters control as 0.57-0.59L/Kg, the low-temperature flexibility of strand can be improved, in addition, chlorion can also be suppressed the corrosion of steel, more can improve the red brittleness that copper causes in steel, serve beyond thought technique effect.
