Die-casting mould steel ingot whole-process full-sealing gas protection casting device

Abstract

The invention relates to a die-casting mould steel ingot whole-process full-sealing gas protection casting device which comprises an outer barrel and an inner barrel coaxial to a central casting pipe.An annular top plate and an annular porous bottom plate are arranged between the outer barrel and the inner barrel; the outer barrel, the inner barrel, the top plate and the porous bottom plate forman annular cavity; an argon ring is arranged in the annular cavity; one end of the argon ring stretches out of the annular cavity and is connected with an external gas source; a support plate for supporting a steel ladle is arranged above the top plate; an annular clamping groove is formed in the surface of the support plate; a steel ladle bottom plate is arranged in the annular clamping groove; and the bottom part of the outer barrel of the casting device is sealed through argon sealing of a flexible material arranged on a horn mouth of the casted central casting pipe. According to the die-casting mould steel ingot whole-process full-sealing gas protection casting device provided by the invention, the full-sealing gas protection casting of the casting system can be conveniently ensured, and molten steel cannot suck air or generate secondary oxidation during the whole casting process, so that the aim on controlling the inner quality and the performance of a steel plate is achieved.

AI Technical Summary

Benefits of technology

The technical effect of this patented method for protectively filling an inside space within a cast iron production facility while maintaining good surface conditions without contamination or damage caused by excessive air exposure. This helps improve productivity and reduce costs associated with producing high-quality products such as stainless steel plates.

Problems solved by technology

This patented problem addressed by this patents relates to the poorly controlled transferring or flow properties associated with dies castings used in industrial processes such as foundry operations where they may be exposed to atmospheric air containing sulfur compounds that cause corrosive reactions between iron atoms within them. These issues lead to defects called white spalls when these materials penetrate into cracks formed through the metal shell of the tool body after being poured from an open bottom gate. To solve this issue, several methods have been developed including coated tools and improved design techniques aimed towards better control over liquid metals' movement inside the cavity.
