Section bar cast-rolling method and system based on horizontal cast-rolling mill

Abstract

The invention discloses a section bar cast-rolling method and system based on a horizontal cast-rolling mill. The section bar cast-rolling system based on the horizontal cast-rolling mill is characterized in that the cast-rolling mill comprises a smelting furnace, a front chamber, a melt distribution mechanism and a cast-rolling mechanism; the smelting furnace and the front chamber are connected through a connecting mechanism, and melt in the smelting furnace enters the front chamber through the connecting mechanism; the melt in the front chamber flows into the cast-rolling mechanism through the melt distribution mechanism; the cast-rolling mechanism comprises an upper roller (1) and a lower roller (2); the axes of the upper roller and the lower roller are parallel to each other and located on the same vertical plane; molding cavities are formed in the roller surface of the upper roller or the lower roller; in the cast-rolling process, the upper roller and the lower roller are driven by a driving mechanism to rotate; the upper roller and the lower roller are opposite in rotating direction; and the melt is cooled in the cast-rolling mechanism and cast-rolled into section bars, and the section bars are transversely output. The section bar cast-rolling method and system based on the horizontal cast-rolling mill are easy to implement and high in generating efficiency.

Description

technical field [0001] The invention relates to a profile casting and rolling method and system based on a horizontal casting and rolling machine. Background technique [0002] Profiles generally refer to metal profiles. Profiles are widely used in the manufacturing industry and construction. Profiles generally include angle steel, I-beam, aluminum alloy profiled profiles, etc. The general process for profile preparation is: ingot casting-heating-extrusion molding . There are disadvantages of coarse grains and high energy consumption in the ingot casting process, and the whole process has large investment, high cost and long production line; [0003] In addition, Chinese Patent Publication No. 105312520A discloses a silicon carbide particle-reinforced aluminum-based composite profile casting-rolling forming equipment and casting-rolling method; its core technical solution is: a silicon carbide particle-reinforced aluminum-based composite slurry preparation device, Sliding ...

AI Technical Summary

Problems solved by technology

The core of the system is to use a "vertical" casting and rolling machine to realize the integrated cooling and rolling of profiles, which has high efficiency, but the general profile length is more than 6 meters. Therefore, the vertical casting and rolling machine used in this scheme is only suitable for The function of preparing shorter profiles (generally no more than 1 meter), therefore, the scope of application is greatly limited

In addition, the vertical casting and rolling mechanism also has the following disadvantages: the side seal mechanism is prone to liquid leakage, and once the liquid leaks, it is easy to damage the entire casting and rolling system

[0004] In addition, the system can only prepare one profile separately, and the production efficiency is low
