Continuous casting crystallizer

Abstract

The invention discloses a continuous casting crystallizer, and in particular relates to a continuous casting crystallizer for producing copper alloy and aluminum alloy pole materials for electric work. The continuous casting crystallizer comprises a frame, a crystallization wheel, a steel strip, and a die cavity which is formed by sealing an outer edge of the crystallization wheel by the steel strip and extends from a casting opening to a throwing outlet along the circumferential direction of the crystallization wheel; the radial outside of the steel strip is provided with an external coolingdevice which is fixed on the frame, corresponds to the die cavity, and extends from the casting opening to the throwing outlet along the circumferential direction of the crystallization wheel; the radial inside of the crystallization wheel is provided with an internal cooling device which is fixed on the frame, corresponds to the die cavity, and extends along the circumferential direction of the crystallization wheel, one end of the internal cooling device is located at the casting opening at one side of the die cavity, and the other end of the internal cooling water pipe extends to the casting opening and is located at one side corresponding to the die cavity. The cross section of the die cavity has good consistency of cooling intensity, therefore, the quality of casting blanks is good, and the continuous casting crystallizer is applicable to continuous casting production of copper alloy and aluminum alloy pole materials for the electric work.

Description

technical field [0001] The invention relates to a continuous pouring equipment, in particular to a crystallizer used for producing copper alloys and aluminum alloys for electric rod continuous casting machines. Background technique [0002] At present, the crystallizer of the continuous casting machine used to produce copper alloy and aluminum alloy electrical rods usually includes a steel belt, a steel belt wheel, and a crystallization wheel. The steel belt passes through the crystallization wheel and multiple steel belt wheels in turn and returns to the crystallization wheel. , the steel belt is guided, tightened and tightly attached to the crystallization wheel by multiple steel belt wheels, and the outer edge of the crystallization wheel is closed by the steel belt to form a cavity extending from the casting port to the casting outlet along the circumference of the crystallization wheel. After injection, it is forced to cool and crystallize in the cavity to form a cast s...

Problems solved by technology

[0004] However, in the current crystallizer, the distance for the crystallization wheel to turn from the casting exit to the casting port is short, and after the steel strip leaves the crystallization wheel, it must go through the steel belt wheel cycle before returning to the crystallization wheel again. The position of the steel belt wheel is also equipped with a spray cooling device to further cool the steel belt, so the temperature of the crystallization wheel at the position of the casting port is much higher than the temperature of the steel belt, so the cooling intensity of the molten metal in the circumferential direction of the cross section of the cavity is different. Seriously affects the metallographic structure of the slab, so the poor quality of the slab has a serious impact on the subsequent processing of the tying process, and has a serious impact on the performance of the final product
