AI Technical Summary

Technical Problem

Existing horizontal and inclined casting and rolling methods suffer from problems such as uneven solidification and crystallization, inclusions and bubbles remaining inside the plate, large performance differences when multiple metals are combined, and easy breakage of the casting nozzle. There is a lack of mature casting systems for vertical casting and rolling.

Method used

A vertical casting and rolling gating system was designed, including a front box, a closed channel assembly, a casting nozzle, and a flow control device. The casting nozzle is equipped with a serpentine channel and a flow control device. The liquid level is adjusted by laser ranging to achieve stable supply and precise control of molten metal.

Benefits of technology

It improves the internal quality of molten metal, prevents inclusions and bubbles from entering the product, enhances the success rate of multi-layer metal composites, avoids spout breakage, and is suitable for mass production.

Abstract

The invention belongs to the technical field of metal material casting and rolling, and discloses a vertical casting and rolling pouring system which comprises a front box, a closed channel assembly is arranged below the front box, a casting nozzle is arranged at the bottom end of the closed channel assembly, a second launder is arranged on one side of the front box, and a lower pouring pipe is arranged at the end, away from the front box, of the second launder. A first flow groove is formed in the top end of the lower pouring pipe, a first flow control device is arranged at the pouring gate position of the first flow groove, and a second flow control device is arranged at the pouring gate position of the front box. The serpentine channel composed of the first check block, the second check block and the third check block is arranged in the inner cavity of the casting nozzle, so that stable flow supply of molten metal can be achieved. The pouring system is simple in structure, convenient to install and debug and suitable for mass production. And flow is supplied in the vertical direction, slag inclusion and bubbles in the molten metal can float upwards and are prevented from entering a product, and the internal quality of the product is improved.
