Vacuum continuous casting device and method for alloy billets

Abstract

The invention discloses a vacuum continuous casting device and method for alloy billets. The device comprises a smelting chamber and a casting chamber, wherein the smelting chamber is internally provided with a smelting system; a liquid steel pouring system and a collecting system are arranged in the casting chamber sequentially; the smelting chamber is connected with a main vacuum system through a pipeline and a valve; the casting chamber is connected with an auxiliary vacuum system through a pipeline and a valve; the smelting chamber and the casting chamber are separated from each other by main and auxiliary vacuum isolating valves; the main vacuum system and the auxiliary vacuum system are respectively provided with a vacuum instrument and an inflating/deflating system which are used for displaying and adjusting vacuum degrees; and the smelting chamber is provided with a smelting material vibrating system. Continuous casting of the alloy billets are performed by a single-point vibrating crystallizer, so that the continuous casting requirements of special alloy are met, the processing procedures of generating alloy ingot risers, cutting of skins and forging to form square billets are avoided, and the cost can be reduced by over 30 percent.

Description

technical field [0001] The invention relates to the casting technology of alloy billets, in particular to a vacuum continuous casting device and casting method for alloy billets. Background technique [0002] The casting technology of alloy blanks belongs to the production of heat-resistant alloys, corrosion-resistant alloys, electrothermal alloys, ultra-pure alloys, high-temperature alloys and other special alloy rods, tubes, plates, wires, wires, profiles and master alloys for precision casting. field of expertise. [0003] At present, the production process of heat-resistant alloys, electrothermal alloys, ultra-pure corrosion-resistant alloys, memory alloys, and high-temperature alloy blanks (master alloys) is to pour the qualified alloy liquid smelted under vacuum into the pre-baked steel ingot mold, and wait for After cooling down, break the vacuum and transport it to the factory building, then use a lathe to cut the riser, remove the outer skin, and send it to the for...

Problems solved by technology

[0008] The object of the present invention is to provide a vacuum continuous casting device and casting method for alloy blanks, which overcomes the problems of existing heat-resistant alloys, corrosion-resistant alloys, electrothermal alloys, ultra-pure alloys, high-temperature alloys and other special alloy rods, tubes, plates, wires, and wires. Due to the complex processing procedures, excessive process material consumption, low success rate, and high production costs in the production technology of steel and profile materials, the continuous casting of alloy blanks is carried out by using single-point vibrating crystallizers to meet the requirements of continuous casting of special alloys, avoiding the occurrence of The processing procedure of alloy ingot riser, skin cutting, and forging to billet reduces the power consumption and heat energy loss caused by multiple heating, avoids high-decibel noise pollution and large equipment investment produced by large forging hammers, and can reduce More than 30% of the cost
