Vacuum continuous casting production equipment

Abstract

The invention discloses vacuum continuous casting production equipment. The vacuum continuous casting production equipment comprises two vacuum degassing furnaces, an intermediate furnace, an alloy furnace, a crystallizer and a continuous casting machine, wherein a furnace cover and a crucible are arranged on each of the vacuum degassing furnaces; an intermediate furnace sealing cover, a chute anda first stopper rod are arranged on the intermediate furnace; a first base is arranged in the intermediate furnace; the first stopper rod is pressed against a concave hole in the first base; an alloyfurnace sealing cover and a second stopper rod are arranged on the alloy furnace; a second base is arranged in the alloy furnace; the bottom end of the second stopper rod is pressed against a concavehole in the second base; a sliding gate nozzle is arranged in the alloy furnace; a first drainage pipe is arranged at the lower end of the sliding gate nozzle; a second drainage pipe is arranged at the lower end of the second base; the crystallizer is arranged at the lower end of the alloy furnace; a temperature measurement system is movably inserted on the alloy furnace sealing cover; the continuous casting machine is fixedly arranged at the lower end of the crystallizer; and a pulling head of the continuous casting machine penetrates through the bottom of the crystallizer. The vacuum continuous casting production equipment is reasonable in structural design, and is suitable for mass promotion; and the loss of alloy materials is small.

Description

technical field [0001] The invention relates to the technical field of continuous casting equipment, in particular to a vacuum continuous casting production equipment. Background technique [0002] The continuous casting process is that after the molten steel produced by the converter is refined in the refining furnace, the molten steel needs to be cast into billets of different types and specifications. The continuous casting section is the production process of continuously casting the refined molten steel into billets. The main equipment includes a rotary table, a tundish, a crystallizer, and a tension leveler. [0003] In the prior art, vacuum smelting + semi-continuous casting of ingots or non-vacuum continuous casting is often used for smelting and casting of alloy materials such as copper alloys and aluminum alloys; however, the above two methods of smelting and casting alloys generally exist: 1.

Problems solved by technology

[0003] In the prior art, vacuum smelting + semi-continuous casting of ingots or non-vacuum continuous casting is often used for smelting and casting of alloy materials such as copper alloys and aluminum alloys; however, the above two methods of smelting and casting alloys generally exist: 1. Non-ferrous metals such as copper and aluminum are easy to oxidize, absorb gas, volatilize and absorb impurities during smelting and casting, resulting in defect segregation, shrinkage cavity, shrinkage porosity, inclusions and other defects; 2. The surface roughness of the ingot is poor, and subsequent processing The amount of milling chips increases; 3. The solidification structure of the dummy head and the ingot tail of the ingot produced by semi-continuous casting is uneven, and the head and tail of a single ingot need to be sawed off, and the actual material utilization rate is about 90%; 4. Semi-continuous casting The continuous ingot production process is discontinuous, the production preparation time is too long, and the production efficiency is low
