Embodiment Construction

[0014] Such as figure 1 As shown, the crystallizer of the present invention includes an upper graphite plate 4a, a lower graphite plate 4b, a left graphite side strip 5a, a right graphite side strip 5b, an upper copper plate 3a and a lower copper plate with an upper cooling pipeline 1a and a lower cooling pipeline 1b respectively 3b. Wherein the left graphite side bar 5a, the right graphite side bar 5b are installed between the upper graphite plate 4a, the lower graphite plate 4b, and between the upper graphite plate 4a, the lower graphite plate 4b, the left graphite side bar 5a, the right graphite side bar 5b A cavity 6 is formed, and liquid copper water is injected into the cavity 6 for cooling. The upper copper plate 3a is installed above the upper graphite plate 4a, and the lower copper plate 3b is installed under the lower graphite plate 4b, which is the structure of the existing crystallizer.

[0015] The improvement of this case is: the cross-sections of the left grap...

Abstract

The invention discloses a crystallizer, belonging to the technical field of copper and copper alloy strip plate horizontal continuous casting device and comprising an upper graphite plate, a lower graphite plate, a left graphite strake, a right graphite strake and an upper copper plate and a lower copper plate which are respectively provided with an upper cooling pipeline and a lower cooling pipeline, wherein, the left graphite strake and the right graphite strake are arranged between the upper graphite plate and the lower graphite plate; a cavity is formed among the upper graphite plate, thelower graphite plate, the left graphite strake and the right graphite; the upper copper plate is arranged above the upper graphite plate; the lower copper plate is arranged under the lower graphite plate; the cross sections of the left graphite strake and the right graphite strake are all right trapezoids; and the trapezoid surface is inclined outwards, or the upper surface and the lower surface of the left graphite strake and the right graphite strake are all provided with slot ways. The crystallizer solves the problem that heat load along the motion direction vertical to a copper strip is uneven, and the copper strip produced by the crystallizer does not have the disadvantages of crack, cracked edge, uneven surface and inflection point in casting line.

Description

technical field [0001] The invention discloses a crystallizer, which belongs to the technical field of horizontal continuous casting equipment for copper and copper alloy strip blanks. Background technique [0002] The crystallizer is the key equipment in the horizontal continuous casting production line. The crystallizer for horizontal continuous casting of copper and copper alloy strip blanks is placed at the exit of the soaking furnace. When liquid copper water flows through the crystallizer, the cooling liquid flowing through the cooling pipes arranged in the upper and lower copper plates will cool the copper The liquid heat is taken away, causing it to solidify into a solid, forming copper strips. And in actual production, there are cracks, cracked edges, uneven surface and defects of inflection point in the casting line in the copper strip produced by the existing crystallizer. Analyzing the reason, it is found that it is mainly caused by the unevenness of the therma...
