Abstract
The utility model relates to a heat type continuous casting liquid level control graphite head, which includes a graphite head (3) and a steel bar (1), and is characterized in that a threaded hole (2) is vertically arranged on the graphite head (3) from the top end to the middle, a pin hole (4) is laterally disposed on the graphite head (3) from one side to the middle, and the pin hole (4) is communicated with the threaded hole (2), the lower part of the steel bar (1) is made into an external thread, and the external thread portion at the lower part of the steel bar (1) is inserted into the threaded hole (2) from the top end of the graphite head (3), a short pin (5) is inserted into the pin hole (4), one end of the short pin (5) goes through the steel bar (1) in the graphite head (3) from one side of the graphite head (3) and is inserted into the pin hole (4), the gap of the pin hole (4) between the other end of the short pin (5) and the side face of the graphite head (3) is plugged with refractory mud (6), and the periphery of the connection part of the top part of the steel bar (1) and the graphite head (3) is provided with a refractory material accumulation body (9). The utility model has the extended service life by one to three times.
Description
Technical field
The utility model relates to the graphite head of liquid level control in a kind of hot continuous casting system, is applicable to the liquid level of controlling copper, aluminium and alloy melt thereof in the hot-mold continuous cast technology.
Background technology
In the hot continuous casting system of known both at home and abroad copper, aluminium and alloy thereof, control liquid level height all use three height shown in Figure 2 (high strength, high density, high-purity) graphite head structure.Graphite head rises or descends as required, is pressed into metal bath, makes liquid level rise, descend.By sensor, reach the purpose of accurate control liquid level position.Its structure at graphite head 3 middle machining internal thread through holes, screws in graphite head 3 middle parts with rod iron 1 as shown in Figure 2 afterwards, brasq 6 is filled in the screw thread of graphite head bottom again.Build the refractory material 9 of taper then by laying bricks or stones in graphite head top end face and rod iron junction.During use, graphite head is pressed in the melt 7.The graphite head of this structure has the following disadvantages:
1, graphite head is pressed in the melt soon that brasq will be shed in the melt, and melt enters in the graphite head thereupon, contacts with rod iron and the constantly bottom of corrosion rod iron and the inside of graphite, and graphite head breaks away from rod iron and also falls in the melt.
2, the fire proofed wood parison for a long time can be damaged in melt, thus afterwards melt just constantly the corrosion rod iron enter in the graphite head from the graphite head top, make it rod iron and graphite head is separated from.Because graphite is serious in oxidation more than 500 ℃, metal bath enters screw thread rod iron is corroded, and often causes graphite head to drop or screw thread erodes, and makes whole hot-mold continuous cast work failure.The service life of one three high graphite head only 5～10 times.
Summary of the invention
The purpose of this utility model is to overcome above-mentioned deficiency, and a kind of hot-mold continuous cast liquid level control graphite head of long service life is provided.
The purpose of this utility model is achieved in that a kind of hot-mold continuous cast liquid level control graphite head, comprises graphite head and rod iron, it is characterized in that:
To the centre screwed hole is set vertically from the graphite head top, from the first side direction intermediate lateral of graphite a pin-and-hole is set, described pin-and-hole communicates with screwed hole,
External screw thread is made in described rod iron bottom, rod iron lower external thread part in screwed hole is inserted on the graphite head top,
Insert short pin in the described pin-and-hole, the rod iron that described short pin one end passes in the graphite head from the first side of graphite inserts pin-and-hole, the pin-and-hole gap brasq shutoff between the short pin other end and the graphite head side,
Described rod iron top and graphite head junction outer periphery are equipped with the refractory material accumulation body.
Adopt short pin to be connected between graphite head of the present utility model and the rod iron and can prevent reliably that graphite head from coming off, between graphite head and the rod iron employing be threaded be make be connected more reliable, non-loosening; Pin-and-hole gap between the short pin other end and graphite side is to prevent that melt from entering graphite head with the brasq shutoff, can accurately control liquid level; At rod iron top and periphery, graphite head junction the thread oxidation that the refractory material accumulation body can play protection rod iron and graphite head is set, increases the service life, reduce production costs and enhance productivity.Can prolong 1～3 times service life, reaches 10～30 heats.
Description of drawings
Fig. 1 is the structural representation of the utility model hot-mold continuous cast liquid level control graphite head.
Fig. 2 is a graphite head structural representation in the past.
Among the figure: rod iron 1, screwed hole 2, graphite head 3, pin-and-hole 4, short pin 5, brasq 6, melt 7, liquid level 8, refractory material are piled up body 9, crucible 10.
The specific embodiment
Referring to Fig. 1, the utility model is a kind of hot-mold continuous cast liquid level control graphite head, mainly piles up body 9 by graphite head 3, rod iron 1, short pin 5, brasq 6 and refractory material and forms.
To the centre screwed hole 2 is set vertically from graphite head 3 tops on the described graphite head 3, on graphite head 3, a pin-and-hole 4 is set from graphite head 3 one side direction intermediate lateral, described pin-and-hole 4 communicates with screwed hole 2, external screw thread is made in described rod iron 1 bottom, rod iron 1 lower external thread part is in screwed hole 2 is inserted on graphite head 3 tops, the rod iron 1 that described weak point pin 5 one ends pass in the graphite head 3 from graphite head 3 one sides inserts in the pin-and-hole 4, pin-and-hole 4 gaps brasq 6 shutoff between short pin 5 other ends and graphite head 3 sides.
In rod iron 1 top and periphery, graphite head 3 junction, be coated with earlier with Ludox, the back knotting is as the taper refractory material accumulation body 9 of figure, this refractory material is 100～200 order diamantane sand, the borax that adds 1～2% weight, low amounts of water glass uses the even class instrument of spoon with tapering part shown in the thorough one-tenth figure of fire proofed wood stockpile; Be heated to 800～1000 ℃ of sclerosis with blowtorch then.
