Abstract
The invention discloses an aluminum carbon bale roughing slag controller used for continuous casting, belonging to a fireproof material used for continuous casting. A control block (1) and a screw (2) are connected by an inner wire iron nut (1.3) on the control block (1) and a thread on the screw (2); the bottom of the control block (1) is provided with four same support frames (1.1); the screw (2) is provided with an upper connecting mechanism (2.1) and a lower connecting mechanism (2.2); and the controller is fixed in the bale by the upper connecting mechanism (2.1) and the lower connecting mechanism (2.2) of the screw (2). The control block (1) is manufactured by adopting aluminum carbon materials at certain proportion; the integral height is larger than the height of the traditional bale liquid level, which is about to generate vortex; and the area of the cross section is bigger than the area of a bale steel tapping hole so as to effectively prevent from generating the vortex and prevent slag floating on the bale molten metal surface from being rolled into a tundish to guarantee the casting blank quality. Meanwhile, the support frame (1.1) is high enough to ensure that the molten metal normally flows out of the steel ladle, and the molten metal is poured into the tundish to ensure that the continuous casting process is normally carried out.
Description
Technical field
The invention belongs to refractory for continuous casting, relate generally to a kind of continuous casting with aluminium carbon bale slag-blanking controller.
Background technology
Big bag is claimed ladle, ladle, steel ladle again, is to accept molten steel, carries out the necessaries of continuous casting, and is stable in order to keep in the ladle liquid steel temperature, need add carbonization rice husk or insulation material at molten steel surface, to reduce heat loss.In addition, in order to reach the purpose of external refining, also need add metallurgic auxiliary materials such as synthetic slag.Pouring into a mould latter stage, when big bag liquid level drops to certain altitude, form whirlpool in big bag tapping hole position easily, be involved in tundish to above-mentioned bits, thereby influence slab quality.
Summary of the invention
The object of the invention just is to propose a kind of continuous casting with aluminium carbon bale slag-blanking controller, makes it be applicable to continuous casting production.
The continuous casting that the present invention proposes is made up of controll block (1) and screw rod (2) two large divisions with aluminium carbon bale slag-blanking controller.Wherein, controll block (1) presets internal thread nut (1.3), and 4 identical bracing frames (1.1) are arranged at controll block (1) bottom, and there is cavity (1.2) centre, and last syndeton (2.1) and following bindiny mechanism (2.2) are arranged on the screw rod (2).
The continuous casting that the present invention proposes is with aluminium carbon bale slag-blanking controller; Its controll block (1) adopts aluminium carbon material to process; The constituent of this material and content are: crystalline flake graphite 25-45wt%; One or more 35-55wt% in palm fibre corundum, alundum or the white fused alumina, phenolic resins 10-20wt%, one or more 1-10wt% in metallic silicon power, carborundum powder or the boron carbide powder.
Its process route is: above-mentioned raw materials is processed blank according to certain proportioning, add in the mould gum cover that matches with controll block (1), and preset internal thread nut (1.3), beat in fact, the cold isostatic pressing method moulding is adopted in sealing.Briquetting pressure is 30-120MPa, dwell time 10-20min.The green compact that moulding finishes carry out simple Vehicle Processing again to be handled, to meet the figure paper size.Through after 200-300 ℃ the dried, the surface-coated antioxidizing paint is inserted in the special-purpose kiln and is heat-treated, and heat treatment temperature is 900-1200 ℃, heat treatment time 5-10h.Controll block after the heat treatment (1) is connected with screw rod (2) with internal thread nut (1.3) on the controll block (1) through the screw thread on the screw rod (2), promptly obtains continuous casting with aluminium carbon bale slag-blanking controller.
The continuous casting that the present invention makes has solved the volume slag problem of big bag cast existence in latter stage in traditional casting process well with aluminium carbon bale slag-blanking controller.In the cast later stage, when big bag liquid level drops to certain altitude, be easier to above tapping hole, form whirlpool, be involved in crystallizer to bits.And the continuous casting that the present invention makes can well address this problem with aluminium carbon bale slag-blanking controller.During use, at first this continuous casting is fixed in the big bag through last syndeton (2.1) on the screw rod (2) and following bindiny mechanism (2.2) with aluminium carbon bale slag-blanking controller.This continuous casting is higher than the height that the big bag of tradition liquid level is on the verge of to produce whirlpool with the whole height of the controll block (1) of aluminium carbon bale slag-blanking controller; And the cross section of controll block (1) is greater than the area of big bag tapping hole; Can effectively prevent to produce whirlpool; The bits of avoiding floating over big Baogang liquid level are involved in tundish, thereby have guaranteed slab quality.Simultaneously, the height of bracing frame (1.1) is enough to guarantee that the molten steel normal flow goes out ladle, injects tundish, guarantees normally carrying out of casting process.

Among the figure, 1, controll block, 1.1, bracing frame, 1.2, cavity, 1.3, the internal thread nut, 2, screw rod, 2.1, attend bindiny mechanism, 2.2, bindiny mechanism down.
The specific embodiment
Below in conjunction with accompanying drawing and embodiment the present invention is further described.
This continuous casting adopts aluminium carbon material to process with the controll block (1) of aluminium carbon bale slag-blanking controller, and its constituent and content are: crystalline flake graphite 30wt%, metallic silicon power 4wt%, carborundum powder 3wt%, alundum 30wt%, brown corundum 21wt%, phenolic resins 12wt%.The raw material of said ratio is processed blank, add in the mould gum cover that matches with controll block (1), and preset internal thread nut (1.3), beat in fact, the cold isostatic pressing method moulding is adopted in sealing.Briquetting pressure is 50MPa, dwell time 10min.The green compact that moulding finishes carry out simple Vehicle Processing again to be handled, and makes it to meet the figure paper size.Be that the surface-coated antioxidizing paint is inserted in the special-purpose kiln and heat-treated after 230 ℃ the dried through excess temperature, heat treatment temperature is 950 ℃, heat treatment time 7h.Controll block after the heat treatment (1) is connected with screw rod (1) with internal thread nut (1.3) on the controll block (1) through the screw thread on the screw rod (2), promptly obtains continuous casting with aluminium carbon bale slag-blanking controller.
