Description
Technical field
The utility model relates to a kind of conticaster tundish with the molding fetal that uses in the dry type material working lining building process, belongs to the metal casting technical field.
Background technology
The dry type material is a kind of novel refractory, because the conticaster bakie working lining made from the dry type material has advantages such as long service life, easy construction, easy disintegration, and can also improve slab quality, improve recovery rate of iron, casting machine and even draw stove number and operating rate, reduce production costs, be used widely in recent years.
The steel box mold that the general employing of dry type material conticaster bakie working lining has apparatus for baking and vibrating device is built by laying bricks or stones and is formed.The apparatus for baking of existing mold is burnt to chew by the burning that is fixed on the mold top and constitutes, and box mold top is provided with aperture, burns to chew flame and spray into box mold inside by aperture mold is heated; Vibrator then is directly installed on the mold upper plate.There are the following problems for this mold:
(1) heating is inhomogeneous.Adopt and burn when chewing the flame heat of ejection, each position of mold is heated inhomogeneous, heat up slower away from the burning place of chewing, especially when tundish was dark, the height of mold can surpass 1500mm, burnt the flame of chewing ejection and was difficult to reach the bottom, easily cause the bag end and Bao Bi bottom working lining intensity on the low side even uncured, influence the serviceability of working lining, reduce the tundish life-span, increase inclusion content in the molten steel.
(2) the baking thermal efficiency is lower.Because the interior upper and lower temperature difference of tundish is big during heating, the bottom reaches the baking temperature requirement in the bag in order to make, and must increase gaseous-pressure and prolong stoving time, and heat loss is very big.Simultaneously, this apparatus for baking is also higher to combustion gas and combustion air pressure, flow, stability requirement, has increased operation easier.
(3) vibrator is directly installed on the mold upper plate, and the vibrator temperature is higher during baking, and the life-span is short, has increased maintenance cost.
(4) there is potential safety hazard.For improving the thermal efficiency and make temperature even, the mold sealing is tighter, reveals or baking when midway putting out a fire when burnt gas valve is unexpected, easily gathers combustion gas in the mold and is difficult for discovering, and lighting a fire has explosion danger when careless.
Therefore, developing high performance tundish dry material working lining molding fetal, is the present difficult problems that face of engineers and technicians.
Summary of the invention

Below in conjunction with accompanying drawing the utility model is further specified.
Fig. 1 is a structural representation of the present utility model;
Fig. 2 is the vertical view of Fig. 1;
Fig. 3 is the A-A cutaway view.
Each label is among the figure: 1, combustion-aid air pipe; 2, Gas Pipe; 3, tundish permanent layer; 4, dry type material working lining; 5, steel casing; 6, fire conduction plate; 7, blast pipe; 8, security protection hole; 9, form vibrator; 10, dividing plate.
The specific embodiment
Referring to Fig. 1～Fig. 3, the utility model mainly is made up of steel casing 5, vibrating device, apparatus for baking three parts.The steel casing is welded by thickness 15-20mm steel plate, and appearance and size is according to the thickness decision of required tundish permanent layer 3 inwall sizes and used dry type material working lining 4, and the back draught that the up big and down small maintenance of box shape is certain is convenient to the demoulding.Because tundish is the strip structure, box house is provided with thickness 15-20mm steel dividing plate 10, to strengthen the intensity of steel casing 5, effectively transmits exciting force.Dividing plate 10 is divided into 3-4 subregion with box house, is convenient to control respectively the baking temperature of each subregion.
Apparatus for baking is made up of Gas Pipe 2, combustion-aid air pipe 1 (valve that also is necessary, instrument etc. certainly).Air supply pipe is arranged in the outer upside of casing, 3-4 subregion of corresponding box house drawn 3-4 subtube (valve is controlled separately), subtube uses diameter to be the straight-through mold of the seamless steel pipe of φ 40-60mm bottom, and bottom the mold subregion, round near the wall box place, the circular hole that is processed with diameter and is φ 3-10mm, spacing on the Gas Pipe 2 of mold bottom and be 100-300mm is as burner, and the burner fire hole vertically upward.Be arranged side by side with combustion-aid air pipe 1 in the position on the upper side in Gas Pipe 2 inboards, and be processed with the steam vent that diameter is φ 3-10mm at the corresponding fuel burner nozzle of combustion-aid air pipe 1 downside position, combustion gas can fully be burnt and be begun to heat whole mold from the bottom like this, thermal current rises and continues the heat packs wall, the excessive and local heat uneven phenomenon of upper and lower temperature difference in avoiding wrapping.Can certainly make 3-4 the public Gas Pipe 2 of subregion and a combustion-aid air pipe 1, this moment, Gas Pipe 2 and combustion-aid air pipe 1 passed dividing plate 10, arranged along the case feather edge.
Set up security protection hole 8 about diameter 600mm at corresponding each subregion on the top board of casing, make unburnt combustion gas be easy to diffuse.Take place that valve is revealed and midway during fire-putting-out emergency, security protection hole 8 makes that combustion gas is communicated with the outer atmosphere of bag in the bag, and operating personnel are easy to discover (can add people's hydrogen sulfide gas in the combustion gas), also can effectively avoid forming pressure seal container, the minimizing potential safety hazard.Simultaneously this structure is convenient to the operator and is observed the fuel gas buring situation, reduces operation easier.
For further improving the thermal efficiency, prevent that high-temperature tail gas from discharging from the middle security protection hole 8 of upper plate that to cause wall box to be heated bad, at roof box periphery one loop diameter is φ 100-150mm, the blast pipe 7 of high 200-400mm, the 300-600mm place is provided with fire conduction plate 6 above Gas Pipe simultaneously, fire conduction plate 6 upwards, outward-dipping, the gap that 30-100mm is arranged between the outside and wall box, guiding elevated temperature heat air-flow flows to wall box along fire conduction plate 6, fully contacts with wall box and carries out heat exchange.The tail gas that continues to rise is discharged from the blast pipe 7 at upper box top board edge, and being provided with of fire conduction plate 6 and blast pipe 7 improved the baking thermal efficiency, reduced the top and the bottom temperature difference, reduced the temperature of roof box and last form vibrator thereof.
Place, the centre position in every adjacent two security protection holes 8 is provided with a vibrator firm banking on roof box, be used to install form vibrator 9, make form vibrator 9 bottoms and roof box leave certain distance, prevent that form vibrator 9 temperature from rising too high.In addition, also a cooling duct can be set at the either side of mold long axis, be used for when baking to form vibrator 9 air coolings, vibrator temperature when reducing baking prolongs life-span of form vibrator 9.Casing is divided into 3-4 subregion, therefore 2-3 form vibrator 9 should be arranged.The main shaft of form vibrator 9 is parallel to each other and is horizontally disposed, and the rotation direction of electric machine main shaft should be consistent, and purpose is that the exciting force of many form vibrators 9 is superimposed, and strengthens the exciting force of single unit system.
