Description

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a mold unit and a continuous casting mold,

The present invention relates to a mold unit and a musical instrument including the same.

A typical continuous casting mold serves to solidify the molten steel in the form of a mold when the molten steel is provided in the mold.

In order to solidify the molten steel, a high heat quantity is usually required. For this purpose, a copper alloy having a high thermal conductivity is used.

However, in using such a mold, in addition to having a high heat conductivity coefficient, a proper cooling means for cooling the conducted heat is also required in order to satisfy the condition of high heat quantity of the mold.

The cooling means is configured such that the cooling passage is formed in the wall portion of the mold to allow the cooling water to flow, thereby satisfying the required heat amount.

However, it is necessary to control the total amount of heat according to the material of the molten steel produced at this time, and it is difficult to adjust it by the change of the flow rate of the cooling water.

In other words, although the change in the flow rate of the cooling water can be considered as means for controlling the total heat amount, there is a limit in that the total heat amount is hardly changed even when the flow rate of the cooling water is further increased. However, there is a problem that the cooling water boils.

Thus, there is a limit in controlling the amount of cooling water to control the amount of heat.

Accordingly, there is a need for a study on a mold unit and a musical instrument including the mold unit to solve the above-mentioned problems or limitations.
