Description
Technical field
The invention belongs to smelt placingJi Shu field, it is related to a kind of casting device of Split type multipurpose.
Background technique
Molten steel water-coating port opening and closing member is the equipment flowed out for controlling molten steel from water gap of steel teeming ladle, is divided into stopper rod and packet bottom
Two kinds of control modes of slide gate nozzle.Although slide gate nozzle has been popularized, also there are its use advantages at the rod type mouth of a river, one
In the casting process of a little large-scale roller steel ingots, the molten steel of tundish is also that the rod type mouth of a river is needed to control, and easily controllable molten steel pours
Speed is infused, is suitable for veteran front-line workers and operates, particularly with certain small lot components, casting process can be controlled flexibly
System enhances steel ingot and casting quality.Therefore, rod type does not step down from the stage of history completely, for certain special substances and small
Living, rod type has better using effect than slide type.Rod type control system includes mechanism for opening/closing, stopper rod and nozzle brick three
Point.Mechanism for opening/closing has the diversified forms such as casing, sliding rail, litter again, is link transmission.Stopper rod is by iron core, sleeve brick and stopper brick
Three parts composition, wherein iron core diameter is decided by its elevated temperature strength, generally 30~60mm；It is cased with sleeve brick outside iron core, is used
To protect iron core to corrode and softening transform under high temperature from steel slag；Stopper brick is mounted in core ends, forms Sheng together with nozzle brick
The opening and closing structure of steel drum；When starting mechanical lifting or pressure stopper rod, stopper brick just leaves or closes nozzle brick, so as to controlling steel
Flow size.
Connection type there are two types of the stopper bricks and iron core of production scene at present, first is that screw-type, by the screw thread of stopper brick
Directly it is connect with iron core；Second is that bolt-type, the bulb top of stopper brick is provided with brick hole, and bolt passes through brick hole and is connected with iron core, so
Brick hole is consolidated with fire sand mud afterwards.Bolt-type production is simple, is suitable for the biggish casting of common material batch.For special steel
Accident occurs for the more liquid steel grade of kind aggressivity, easy drop.Screw-type make corrosion resistance it is stronger, but make require compared with
Strictly, higher cost, the steel grade more liquid suitable for special steel grade aggressivity, for the biggish casting of common material batch
Part, operation production cost are higher.
Comprehensive two kinds of connection types, the bolt-type for meeting common material cannot meet the special substance quality of production, meet
The special substance quality of production cannot meet the control of production cost and labor intensity；And iron core connects plug head position due to height
Warm deformation often leads to entire core bar and scraps, and increases production cost, influences manufacturing schedule.Therefore, between different connection types
Production and the contradiction between quality and production and cost, are an intractable technical problem all the time.
Summary of the invention
The object of the present invention is to provide a kind of casting devices of Split type multipurpose, solve prior art pouring molten steel mistake
Cheng Zhong is fixedly mounted bad adaptability to different model connection type chock plug, is difficult to take into account production, matter between different connection types
The problem of being balanced between amount, cost.
The technical scheme adopted by the invention is that a kind of casting device of Split type multipurpose, including successively screw thread is socketed
Core body I and iron core fission II, the lower thread of iron core fission II is socketed with screw rod connector III or bolt connector
IV。
The casting device of Split type multipurpose of the invention, it is further characterized in that:
The lower part core body I is machined with core body and embeds screw hole, processes on the iron core top fission II cored
Split screw, iron core Split screw and core body embed the socket of screw hole screw thread, process cored point in the lower part iron core fission II
Internal embedding screw hole.
The top screw rod connector III is machined with screw screw, screw screw embedded screw hole seperated with iron core
Screw thread socket is machined with screw screw thread in the lower part screw rod connector III, and screw screw thread is used for downward connecting screw formula plug
Head.
The bolt connector IV outer round surface is machined with screw screw, screw screw embedded spiral shell seperated with iron core
The convex shoulder of the socket of hole screw thread, the lower end surface bolt connector IV is used for connecting bolt formula chock plug.
Radially the cored fission of processing is to window for the iron core fission II circumference, along circle in the middle part of screw rod connector III
All radial directions are machined with screw to window, and circumferentially radial direction is machined with bolt-type to window in the middle part of bolt connector IV.
The invention has the advantages that iron core one dividing into three is become dismountable split type from original Contiuum type, especially
The connection plug head position easily-deformable to high temperature, can accomplish to replace at any time, and need not re-work entire iron core, greatly save
Cost solves the problems, such as that the chock plug of different connection types is fixedly mounted in existing apparatus.In addition, for special in production process
Different material can dismantle replacement screw connection type at any time, guarantee quality；The production of material common for high-volume, can tear open
Replacement bolt-type connection type at any time is unloaded, working strength is reduced, saves production cost.The apparatus structure is simple, makes production and matter
It is consistent to have reached height between amount and cost, and has not influenced the basic demand that former iron core uses, has achieved the effect that a core is multi-purpose,
Reduce production cost, can flexibly select chock plug connection type to be assembled according to production plan, increase production efficiency, mention
High product quality.
