Embodiment Construction

[0039] It should be understood that the scope of the present invention should not be limited to the embodiments presented, but would encompass other embodiments apparent to those skilled in the art.

[0040] figure 1 is a side perspective view of a casting mold 1 for casting molten metal 40 such as steel, copper or aluminum. The casting mold 1 comprises a nozzle or pouring spout 2 and a hollow cavity 3 having a desired shape. In this example a rectangular cavity is illustrated. The cavity 3 is generally configured in a rectangular shape with broad sides and narrow sides, and also includes an outer structure 30 and an inner copper plate 10 . Molten metal 40 fills cavity 3 during casting. A thin layer of mold flux 50 is formed between the molten metal and the copper plate, which can cover the entire area of ​​the copper plate 10 and thereby separate the molten metal 40 from direct contact with the inner copper plate 10 .

[0041]During the casting process, molten metal 40 is...

Abstract

The invention relates to a casting mold (1) comprising a copper plate (10) and a plurality of optical fibers (20), each having a plurality of optical fibers arranged to measure the temperature of the copper plate (10) while casting a temperature measuring point (22), wherein molten metal (40) is cast into the casting mold (1) along the axis (Y), wherein the optical fiber (20) is built in the copper plate (10) and is arranged at least upper part. The invention also relates to a method for detecting the temperature distribution of molten metal in a casting mold having at least one copper plate, wherein the molten metal is cast into the casting mold along an axis, said method comprising determining by calculation or measurement ideal melt flow of molten metal in the mold (S10), building a plurality of optical fibers into the copper plate based on the calculated / measured actual melt flow (S20), arranging the optical fibers inside the copper plate on at least the upper portion of the copper plate (S30), A measurement of the temperature is received (S40) and compared with the calculated / measured distribution of the ideal melt flow during the ideal state (S50).

Description

technical field [0001] The present invention relates to a casting mold comprising a copper plate and a plurality of optical fibers arranged to measure the temperature of the copper plate, each optical fiber having a plurality of temperature measuring points arranged to measure the temperature of the copper plate while casting. The invention also relates to a method for detecting the temperature distribution of molten metal in a casting mold having at least one copper plate. Background technique [0002] It is well known in the art that it is important to monitor the temperature of casting molds operating at high speeds. [0003] During the casting process, the typical temperature change cycle is less than ten seconds. This is because the temperature depends on the heat flux of the molten steel. The heat flux can vary depending on the melting temperature, mold flux properties and molten steel movement. Typically, the molten steel flow will change during the casting process...
