摘要:
The invention relates to a casting device (1) having a casting ladle (2), a distribution device (4), and a horizontally moveable transport belt (5) having side boundaries (13, 14), wherein liquid metal, preferably steel, can flow out of the casting ladle (2) onto the distribution device (4), and from there can be applied to the horizontal transport belt (5), the side boundaries (13, 14) of the horizontal transport belt (5) being adjustable across the width of the horizontal transport belt. The invention further relates to a corresponding method.
摘要:
A melt charging system for the horizontal strip casting of a molten metal with a run-out element, in particular with a nozzle (9), is characterized in that at least one heating device (21, 22; 28) is arranged in the region of the run-out element for heating up the run-out element.
摘要:
The invention relates to a device (1) for measuring the flow rate of molten metal in particular, comprising a first vessel (2) and a second vessel (8), wherein the molten metal (3) is supplied in the first vessel (2) and flows into the second vessel (8) by way of a shroud tube (7), wherein the molten metal (3) is stored temporarily in the second vessel (8) and flows into a mold or another vessel (15, 16) by way of at least one first immersion tube (17, 18), wherein the flow rate of the molten metal (3) through the at least one shroud tube (7) and/or the at least one immersion tube (17, 18) is detected by at least one sensor (9, 21, 22) arranged beneath the respective vessel (2, 8). In addition, the invention relates to a method in this regard.
摘要:
The invention relates to a method for equalizing the solidification process of a fusible metal (10), particularly a fusible metal produced by means of strand or strip casting, wherein the fusible metal (10) is subjected particularly to an electromagnetic stirring process, and wherein a magnetic field is applied to the metal located there upstream of the point of the particularly electromagnetic stirring process. The invention proposes that at least one electromagnetic field be applied to the regions (11) of the fusible metal 10 already solidified into a strand on the exterior. The invention further relates to a device for carrying out said method.
摘要:
The invention relates to a casting system (1) particularly with a reservoir (2) for a fluid (3), particularly for molten metal, with a dispensing chamber (5) connected to the reservoir via a connection (4) and with an application device (7), by way of which the fluid (3) can be distributed to the desired width (8) and by way of which the fluid can be distributed on a moving strip (9), wherein a connection between the dispensing chamber (5) and the application device (7) is designed as a closed tubular connection (6).
摘要:
In the casting close to the final measuring of rectangular billets made of metal and the subsequent further processing thereof into metal strips according to the DSC method (direct strip casting) in a horizontal continuous casting system, the cast product (4) is deformed during the solidification thereof into the preliminary strip (5) due to uneven heat dissipation because the top of the strip is cooled only by convection of ambient air and by heat dissipation, while the bottom of said strip is in direct contact with a cooled metal conveyor belt (7). In this manner, the initially complete contact between the cast product (4) and the metal conveyor belt (7) is lost and the strip edges of the cast product arch upwards. In order to ensure in a simple manner maximum contact of the cast product (4) on the metal conveyor belt (7), thus optimizing and equalizing the heat transfer of the cast product (4) to the metal conveyor belt (7) across the entire casting width, the invention proposes that pressure be applied from above to the cast product (4) solidifying into the preliminary strip (5), preferably to the strip edges (6) thereof by means of a pressure device (11) disposed at the end of the metal conveyor belt (7) and, in order to compensate for the suddenly reduced cooling of the bottom of the preliminary strip upon leaving the metal conveyor belt (7), that the bottom of the preliminary strip be additionally cooled in a defined area directly behind the metal conveyor belt (7).
