Casting-rolling machine cooling mechanism

Abstract

The invention discloses a casting-rolling machine cooling mechanism. The casting-rolling machine cooling mechanism comprises casting-rolling rollers. The two casting-rolling rollers are symmetricallyarranged in the vertical direction. A roller shaft is arranged in the center of each casting-rolling roller. The two ends of the roller shafts are mounted on supports through bearings. The casting-rolling rollers are internally hollow. A drainage channel is formed in the center of the left portion of each roller shaft. The left end of each roller shaft is provided with a rotary joint, wherein eachrotary joint communicates with the corresponding drainage channel. The right end of each drainage channel extends into the corresponding casting-rolling roller, and each roller shaft is provided witha drainage hole communicating with the right end of the corresponding drainage channel. Each roller shaft is provided with a water drawing pipe communicating with the corresponding drainage hole. Oneend of each water drawing pipe is fixedly connected with the corresponding roller shaft. Stirring mechanisms are arranged at the positions, inside the corresponding casting-rolling roller, of each roller shaft. According to the casting-rolling machine cooling mechanism, cooling water circulates inside the casting-rolling rollers for cooling, cyclic utilization is achieved, and resources are saved; by means of the stirring mechanisms designed inside the casting-rolling machine cooling mechanism, efficient cooling of the casting-rolling rollers can be achieved; and the casting-rolling machine cooling mechanism is worthy of popularizing to a large extent.

Description

technical field [0001] The invention relates to the technical field of metal smelting, in particular to a cooling mechanism for a casting and rolling mill. Background technique [0002] Casting and rolling is a new process that directly casts and rolls molten metal into semi-finished billets or finished products. The two processes of coagulation and hot rolling are completed between the gaps, and they are completed in a very short time. [0003] When the casting rolls in the original casting rolling mill are hot-rolled, the interior and surface of the parking rolls will generate a lot of heat, resulting in a decrease in the solidification quality of the solution, thereby reducing the efficiency of continuous casting and rolling. Most of the existing technologies use The mechanism for spraying cooling water is designed to cool the surface of casting rolls. On the one hand, the cooling water is inconvenient to collect and wastes a lot, and on the other hand, the cooling effic...
