Abstract
A combined external cooler for fast solidification of cast and rolled workpiece features that two rows of vapour fog nozzles are arranged above and under the exit of casting-rolling region and two rows of compressed air nozzles are arranged above and under the entrance of casting-rolling region. Its advantages include high cooling power and casting-rolling speed, and fining the structure of cast and rolled plate.
Description
The present invention relates to the outer cooling device of a kind of continuous casting and rolling.
Casting is that melt metal is chewed in the tapered region of injecting between two chill rolls by casting, makes metal bath through casting and the rolling made-up belt of directly producing different-thickness.In the casting district, metal freezing mainly is to be delivered on the roller shell with contacting of casting roller by it with the heat that rolling deformation is given out, and constantly takes away the roller shell heat by the recirculated cooling water between the roller core roller shell then, to guarantee carrying out continuously of strip casting process; Not existing together of casting roller and common roll is: it will play condensing crystallizer and rolling strip base.In order to reduce cost, improve existing casting productivity ratio, must make continuous casting and rolling realize " fast "; But, along with the raising of roll casting speed, the casting product solidify with cooling procedure in will discharge more heat, therefore, the cooling capacity that improves casting system is to realize the key of rapid roll-casting.
The purpose of this invention is to provide a kind of external cooler that utilizes new hot channel conduction to improve the cooling capacity of casting system, to improve whole casting efficient.
The present invention respectively is provided with two steam discharge atomizing nozzles at the upper and lower of casting district outlet side, respectively up and down roll surface and plate face is forced cooling, the heat that utilizes the latent heat of vaporization of cooling circle matter to take away in the strip casting process to be produced; And at the upper and lower of casting district entrance side the one row pressure air nozzle that contracts is set respectively the inlet roll surface is purged, further to take away heat and to guarantee the roll surface drying.
The present invention increases roll casting speed for the cooling capacity that improves casting system, and the institutional framework of refinement casting plate all produces positive effect, and compared with prior art, cooling effectiveness improves 1/3, and roll casting speed improves 1/3.
Description of drawings:
Fig. 1: structure principle chart of the present invention.
The present invention is further illustrated below in conjunction with accompanying drawing.
As shown in Figure 1, upper and lower at casting district outlet side respectively is provided with two steam discharge atomizing nozzles 1, respectively to roll surface 2 and plate face 3 are forced cooling up and down, and at the upper and lower of casting district entrance side one row pressure, 4 pairs of inlets of air nozzle roll surface that contracts is set respectively and purges, further to take away heat and to guarantee the roll surface drying.The present invention has carried out the external cooling pilot production under the various roll casting speeds on the quick strip casting mill of Φ 400 * 500mm, result of the test shows that external cooling has remarkable result for increase system cools ability, raising roll casting speed.
