Description

Vacuum horizontal continuous casting and die casting device

Technical Field

The utility model relates to the technical field of continuous casting in the metallurgical industry, in particular to a device for vacuum horizontal continuous casting and die casting.

Background

Horizontal continuous casting refers to a continuous casting type in which molten steel is poured into a horizontally placed mold from a horizontal direction, and the solidification process of a cast slab and the movement in a casting machine are in a horizontal state until reaching a cooling bed. The horizontal continuous casting technology is a technology for producing billets, which is common at present and is suitable for producing small-section billets.

High-temperature alloy and precision alloy are important materials of aerospace components, and nearly ten thousand tons of high-temperature master alloy are cast annually in China, and the production value reaches hundreds of millions of yuan. Although the preparation technology of high-temperature master alloys is relatively mature, a plurality of problems still need to be solved. In the technical field of continuous casting in the world major iron and steel industry countries, the continuous casting ratio of carbon steel alloy is more than 90%, the continuous casting ratio of stainless steel and heat-resistant steel is also more than 60%, but the continuous casting ratio of high-temperature alloy is less than 1%. This is because superalloy master alloys are currently being cast using conventional production processes, namely vacuum-smelted metal molds. However, it is difficult to control the number of inclusions in the master alloy by die casting. During the casting process, the crucible material, the nonmetallic material in the pouring spout and the dross are inevitably brought into the ingot, so that the quality of the high-temperature master alloy is affected. Particularly for use on aerospace components, serious accidents may occur.

On the other hand, the traditional metal die casting production process determines that the casting rod is cooled from bottom to top, so that a casting concentrated shrinkage cavity riser which gathers a large amount of scum on the top of the casting rod is generated, the casting concentrated shrinkage cavity riser must be cut off when in use, the surface of the casting concentrated shrinkage cavity riser needs to be polished or even processed when a high-temperature master alloy bar is used, and finally, the yield of the master alloy is only 80-85%, and a large amount of resource waste is caused.

Some problems of the existing die casting method for producing high-temperature alloy master alloy: (1) the master alloy electrode produced by the casting method of the low-yield low-vacuum induction smelting steel tube for producing the master alloy cast ingot by the die casting method needs to cut the head and the tail, the loss rate of the electrode after each electrode is cut off the head and the tail is about 3-5%, and the high-temperature alloy material is precious and has higher cost.

(2) The shrinkage cavity of the master alloy ingot produced by the die casting method cannot eliminate the larger shrinkage cavity size (the shrinkage cavity diameter is about 15mm wide as shown in fig. 1) formed by the common steel pipe casting method, and the shrinkage cavity size (the shrinkage cavity size is about 5mm wide as shown in fig. 2) of the alloy can be improved by reducing the casting speed and the casting temperature and using a heat insulation riser, but the elimination of electrode shrinkage cavities cannot be fundamentally solved.

(3) Large-size inclusion or slag inclusion in master alloy produced by the die casting method is difficult to remove in the process of pouring the master alloy produced by the die casting method, the risk of entering a die pipe by using a diverter plate body material is increased, the possibility of floating up the large-size inclusion or slag inclusion in molten metal is increased by adopting a horizontal continuous casting tundish structure, and the risk of entering an ingot by the large-size inclusion or slag inclusion is reduced.

(4) The die casting method is high in batch production cost, and because the high-temperature alloy master alloy has increasingly strict requirements on inclusion content, oxygen element/nitrogen element content and secondary shrinkage cavity size of an electrode, a flow distribution disc, a heat insulation riser and a die pipe are inevitably used, the flow distribution disc and the heat insulation riser are consumable materials, the die pipe can only be used once, the use times of the die pipe are generally 5-8 times, but the rejection rate of the master alloy die pipe with special requirements is higher, and the master alloy die pipe is likely to be scrapped after being scalded once.
