![]() Arrangement for continuous casting of strip
专利摘要:
Apparatus for continuously casting strip material onto a casting surface (14) is disclosed, comprising a tundish (22) for receiving and holding molten metal (20) having a nozzle therein. The nozzle comprises an orifice passage (80) defined between a first inside surface (30) and a second inside surface (34), wherein at least a portion of at least one inside surface (30) comprises an insert (50) disposed against the tundish (22). A nozzle gap of at least 0.254mm (0.010 inch) is maintained, an outer portion of the insert (50) is able to be disposed to within 3.048mm (0.120 inch) of the casting surface (14), and at least a portion of the outside surface (36) of the tundish (22) at the orifice of the nozzle (24) is able to be disposed to within at least 0.508mm (.020 inch) of the casting surface. 公开号:SU1165225A3 申请号:SU813280700 申请日:1981-05-08 公开日:1985-06-30 发明作者:Эдвард Марингер Роберт 申请人:Баттель Дивелопмент Корпорейшн (Фирма); IPC主号:
专利说明:
The invention relates to the field of metallurgy, and more specifically to the continuous casting of metals and alloys. The purpose of the invention is to improve the quality of the cast strip. FIG. 1 given a device for the continuous casting of the strip, general view; in fig. 2 - tundish, section; in fig. 3 - the same, front view; in fig. 4 9 - embodiments of the tundish; in fig. 10 - liner intermediate tundish bucket, top view; in fig. 11 - nozzle tundish, a section on an enlarged scale. The device for continuous strip casting comprises a tundish 1 with a nozzle 2 for feeding metal to the casting surface 3 of the device. At the upper edge of the nozzle 2, there is an insert 4 of refractory material, the front end surface of which 5 faces the casting surface 3 of the device. In the lad 4, it is possible to reciprocate relative to the casting surface 3 by means of manual or automatic registration. The insert 4 holds-30 c on the upper edge of the nozzle 2 by means of a weight or mechanical device or by means of a groove made in the wall of the tundish. The front face 5 of the insert 4 is chamfered parallel to the casting surface 3 and is located at a distance of q to 3 mm from it. The nozzle 2 of the tundish 1 has a channel of constant cross-section along the entire length with a minimum clearance of b, which is at least 0 , 25 mm. Intermediate casting bucket 1 is made of a material with good insulating properties, such as fibrous kaolin, refractory clay, graphite, quartz, clay graphite, boron nitride, silicon nitride, boron carbide, silicon carbide, alumina, zirconium dioxide, and various combinations 1 telnye devices. The height of the static pressure of the metal in the tundish 1 must be maintained at a constant level. v The casting process to provide a relatively constant static head pressure in the nozzle opening. The feed rate of the metal into the tundish should correspond to the flow rate of the metal from the nozzle 2 to the casting surface. 3. The casting surface (drum) rotates at a speed of 25 to 1250 rpm. The insert is installed at a distance of up to 3 mm, preferably 0.25 - 0.5 mm from the casting surface 3, depending on the thickness of the strip to be cast, Using the proposed device, it is possible to cast high-quality materials, including amorphous ones, and, moreover, the device can be raised. quality of the cast strip. 252 or mixtures of these materials. The insert 4 can also be made from these materials, but preferably from boron nitride, silicon nitride, silicon carbide, boron carbide, zirconium dioxide or quartz. The casting surface 3 can be made in the form of a cooled drum, wheel or belt, mainly of a dispersion strengthened alloy containing approximately 90% copper. However, steel, brass, aluminum, aluminum alloys and other materials can be used. The width of the casting surface 3 should correspond to the width of the cast strip, and the speed of movement of the casting surface 3 in the case of a drum is approximately equal to 25 - 1250 rpm. The operation of the device is as follows. The molten metal is fed to the heated tundish 1, from which it falls through the nozzle 2 onto the casting surface 3 and forms into a strip which is removed with a knife. For heating the tundish 1 and liner 4, as well as for heating the metal, various heatings are used Fig.z FIG. five
