Description

A kind of round steel cast dies holder device and its application

The present patent application is divisional application, parent application number：2016100561448；Female case title：A kind of round steel casting side Method, cast dies and its holder device；Parent application day：2016-01-27.

Technical field

The invention belongs to round steel casting fields, specifically, being related to a kind of round steel cast dies holder device and its application.

Background technique

Casting be a kind of common metal heat processing technique, in particular to by Metal Melting at meeting necessarily required liquid simultaneously Pour into casting mold, through cooled and solidified, level processing after obtain predetermined shape, size and performance casting technical process.Casting It makes and is divided into sand casting and Special Processes of Metal Castings, sand casting is using sand as molding material；Special Processes of Metal Castings then include model casting, Permanent mold casting etc..Using steel pipe as mold, referred to as punching block, the structure of punching block is simple for the casting of traditional round steel, so circle The casting of steel seems very simple, and actually opposite.Traditional round steel casting technique positions punching block, punching block position precision using human eye It is low；Molten steel cast when molten steel be easy contacted with punching block inner wall, molten steel splashes generation steel ball, so that round steel surface is recessed, influence Round steel surface quality；Punching block each section is uneven with steel contacts, keeps punching block temperature distortion serious, tired so as to cause round steel depanning It is difficult；Meanwhile no matter punching block inner wall is damaged or punching block shape bending deformation, can all reduce the service life of punching block, or even make Punching block is scrapped.

Chinese Patent Application No. 201520449238.2, the patent document in publication date on November 11st, 2015, discloses one Kind round steel ingot mould, including die body, lifting lug and heat-insulating shield, die body are equipped with inner cavity, and lifting lug is fixedly installed in die body side wall, heat-insulating shield peace Loaded on die body inner wall suitable for reading, the lumenal cross-section is circle, and the cross section of die body outer surface is wave polygon.It is logical It crosses and sets cylindrical or truncated cone-shaped for inner cavity, reduce the difficulty of processing of inner cavity.It sets the cross section of die body outer surface to Wave polygon increases the heat dissipation area of steel ingot side, accelerates the radiating rate of molten steel, and outermost molten steel is made to be quickly cooled down shape At chill, and accelerate the thickness growth rate of chill, so that it is enough to bear the static pressure in molten steel casting process, prevent Chill cracks.Meanwhile the precision of each size will not influence the dimensional accuracy of round ingot on the outside of round steel ingot mould, therefore, It is low to the requirement on machining accuracy of round steel ingot mould outer surface, reduce process and working hour, save the cost.But disclosed in the utility model Structure is complicated for technical solution, and processing and manufacturing is difficult, and the control of molten steel casting position is difficult, and casting efficiency is not high.

Chinese Patent Application No. 201320266585.2, the patent document in publication date on October 16th, 2013, discloses one Kind mould buggy, including Mo Che and ingot mould, it further includes the connecting rod of the output end connection of hydraulic cylinder and one end and hydraulic cylinder, institute The other end for stating connecting rod is flexibly connected with ingot mould, be fixedly installed on the mould vehicle lean forward respectively to ingot mould and hypsokinesis rise limit The front apron and rear baffle of position effect.The utility model passes through ingot mould slant setting in casting, restores to hang down after casting complete Straight state achievees the purpose that extend vaccum sensitive stove steel ingot length, so that the raw material specification with electroslag refining furnace is adapted.It should Utility model only increases hydraulic transmission equipment in the case where not changing original vaccum sensitive stove furnace structure, and investment reduction accounts for It is small with space, expand vacuum induction and smelts and electric slag refusion and smelting trimmed size range.Technical solution disclosed in the utility model When applied to round steel casting, according to uphill casting, round steel surface inhomogeneous cooling certainly will be made even, thus cause round steel hardness, close Degree is uneven, of poor quality；Simultaneously using a mould vehicle piece round steel low efficiency of casting, it is not suitable for producing in batches.
