Abstract
The invention discloses a cooling unit for heated mold continuous casting equipment, which comprises a shell (1). The cooling unit is characterized in that the front end of the shell (1) is provided with an inert gas cover (3) and an adjusting valve core (2) is arranged in the shell (1). A cooling fluid inlet opening (5) and an inert gas inlet opening (6) are formed on the shell (1). The front end of the shell (1) is also provided with a glossy outer arc (1-a) and a glossy inner arc (1-b). The inner surface of the shell (1) is provided with an annular square groove (1-c) and the front end of the adjusting valve core (2) is provided with a glossy arc surface (2-b). The cooling unit can ensure that cooling fluid is sprayed out uniformly and the flow of the cooling fluid can be controlled freely. Furthermore, the inert gas protection cover arranged at the front end effectively protects the metal at the front end of a mold opening, thereby solving the key problems of non-uniform liquid spraying of a cooling structure, difficult control of cooling fluid flow, no protection for the metal at the front end of the mold opening and the like.
Description
Technical field
The present invention relates to the improvement technical field of quencher moiety structure in a kind of hot-mold continuous cast technology, especially relate to a kind of cooler that is used for hot-mold continuous casting apparatus.
Background technology
What the cooling structure of pulling equipment adopted in the existing hot-mold continuous cast technology is that cooling fluid gushes out from the hole metal is cooled off in the inboard evenly perforate of ring pipe.Its shortcoming is: the cooling fluid ejection is inhomogeneous, causes heat dissipation metal inhomogeneous; Coolant rate is wayward, and is prone to cause the forward end sputter, thereby makes the molding port oxidation; Cooling structure front end unprotect causes burning.According to the requirement of hot-mold continuous cast technology, the even degree of supercooling difference that can make the molding port metal of inhomogeneous cooling causes to form monocrystal or continuous columanar structure during continuous casting; Protection is improper in the casting process will cause oxidation on metal surface, thereby has a strong impact on the directional solidification performance of products.
Summary of the invention
The objective of the invention is to avoid the weak point of prior art and a kind of cooler that is used for hot-mold continuous casting apparatus is provided, thereby effectively solve the problems of the prior art.
The object of the invention is realized through adopting following technical scheme: the described cooler that is used for hot-mold continuous casting apparatus; Include housing 1; Its characteristics also include: the front end of described housing 1 is provided with inert gas cover 3; Be provided with regulating spool 2 in the housing 1, housing 1 is provided with cooling fluid and enters hole 5 and enter hole 6 with inert gas, and the front end of housing 1 also is provided with smooth external arc 1-a and smooth interior circular arc 1-b; Housing 1 inner face is provided with annular square groove 1-c, and regulating spool 2 front ends are provided with smooth arc surface 2-b.
Described regulating spool 2 is connected with housing 1 through the screw thread on it 10, between housing 1 and the regulating spool 2 sealing ring 4 is installed, and described inert gas cover 3 links to each other with housing 1 through first screw 7, is provided with fluid sealant 8 between housing 1 and the inert gas cover 3.Described housing 1 is fixedly connected with installing rack 11 through second screw 9.
The invention has the beneficial effects as follows: the described cooler that is used for hot-mold continuous casting apparatus, this cooler can make cooling fluid evenly spray, and the flow of cooling fluid can be controlled arbitrarily; And increased the inert gas shielding cover at front end, carried out effective protection, solved that the cooling structure hydrojet is inhomogeneous, coolant rate is wayward and critical problem such as type mouth front end metal unprotect for the metal of type mouth front end.
Description of drawings
Fig. 1 is a structural principle sketch map of the present invention;
Fig. 2 is the plan structure sketch map of Fig. 1 of the present invention.
Concrete implementation
Like Fig. 1, shown in 2; The described cooler that is used for hot-mold continuous casting apparatus includes housing 1, and its characteristics also include: the front end of described housing 1 is provided with inert gas cover 3; Be provided with regulating spool 2 in the housing 1; Housing 1 is provided with cooling fluid and enters hole 5 and enter hole 6 with inert gas, and the front end of housing 1 also is provided with smooth external arc 1-a and smooth interior circular arc 1-b, and housing 1 inner face is provided with annular square groove 1-c; Regulating spool 2 front ends are provided with smooth arc surface 2-b, and the forward part 2-a of regulating spool 2 is a smooth surface.
Described regulating spool 2 is connected with housing 1 through the screw thread on it 10, between housing 1 and the regulating spool 2 sealing ring 4 is installed, and described inert gas cover 3 links to each other with housing 1 through first screw 7, is provided with fluid sealant 8 between housing 1 and the inert gas cover 3.Described housing 1 is fixedly connected with installing rack 11 through second screw 9.
The described cooler that is used for hot-mold continuous casting apparatus, each several part junction all adopt the sealing of 8 fluid sealants, to guarantee its sealing; Its regulating spool 2 can move forward and backward; This cooler is installed on the hot-mold continuous casting apparatus pulling equipment, and center line is coaxial with hot-mold continuous casting apparatus type mouth center, when adopting hot-mold continuous cast prepared metal; Cooling fluid is entered 5 inlet openings, hole from cooling fluid and is got into; The acting in conjunction that cooling fluid receives housing 1 and regulating spool 2 will be certain angle to the ejection of cooler rear end, because the nozzle that housing 1 and regulating spool 2 are formed is an annulus, cooling fluid can evenly spray; Through regulating the flow that regulating spool 2 can reduce or increase cooling fluid forward or backward; Sealing ring among the annular square groove 1-c can guarantee that cooling fluid can be from not flowing out between housing 1 and the regulating spool 2; Simultaneously, inert gas advances hole 6 air admission holes through inert gas and gets into, and then from evenly ejection of external arc 1-a, has protected the metal of type mouth front end, has improved the performance of hot-mold continuous cast metal.
The cooler of this hot-mold continuous casting apparatus, it is inhomogeneous to have solved in the cooling procedure cooling fluid ejection, and critical problems such as the wayward and type mouth front end metal unprotect of coolant rate are for high-quality hot-mold continuous cast metal material provides equipment guarantee.
