Abstract
The utility model discloses a kind of continuous casting production submersed nozzle high-efficient cooking apparat, by combining as the go-cart of completed cases and half casing are formed; Go-cart is made up of riser and base plate, and be provided with the support for blocking many submersed nozzles inside riser, the bottom of base plate is provided with wheel; The side of half casing and bottom are opening, and its top is provided with the air admission hole communicated with the nozzle on inner chamber top, and bottom is propped by the bracing frame being fixed on side wall lower ends, and lower sidewall has venthole.Tool has the following advantages: the baking that 1, once simultaneously can complete many submersed nozzles, greatly improves cured effect and baking speed, only mouth of a river temperature can be preheating to more than 1000 DEG C from room temperature with 60 points, improve the baking thermal efficiency 20%.2, heated submersed nozzle by nozzle, ensure that mouth of a river inside and outside wall heating temperature is even, mouth of a river neck preheating is abundant.3, good airproof performance, gas medium consumes low, not only can reduce baking cost, and can reduce environmental pollution.
Description
Technical field
The utility model belongs to apparatus for baking technical field, is specifically related to a kind of continuous casting production submersed nozzle high-efficient cooking apparat.
Background technology
Submersed nozzle is continuous casting production important refractory material used.Research shows, before using, fully preheating is the important channel of improving submersed nozzle Focal drug-block phenomenon.If preheating is insufficient, easily there is crackle and fracture in mouth of a river neck, falls in crystallizer and can impact slab quality.At present, conventional preheating method is roasting mode, comprises induction coil baking and gas toast two kinds.Induction coil toasts the heater complex structure adopted, and security maintenance requires high, and power consumption cost is large; Gas toast many employings extensive style baking method, gas consumption amount is large, top and the bottom, the mouth of a river are heated uneven, and the mouth of a river picks and places inconvenience, and baking efficiency is low.
Summary of the invention
It is simple, reasonable in design that the purpose of this utility model is to provide a kind of structure, effectively can overcome the continuous casting production submersed nozzle high-efficient cooking apparat of the many deficiencies of existing roasting mode.
For achieving the above object, the technical solution adopted in the utility model is: this device is by combining as the go-cart of completed cases and half casing are formed; Go-cart is made up of riser and base plate, and be provided with the support for blocking many submersed nozzles inside riser, the bottom of base plate is provided with wheel; The side of half casing and bottom are opening, and its top is provided with the air admission hole communicated with the nozzle on inner chamber top, and bottom is propped by the bracing frame being fixed on side wall lower ends, and lower sidewall has venthole.
During use, support submersed nozzle being put into go-cart blocks, promote dolly and half casing is combined, push in half casing by go-cart, submersed nozzle is placed in the inner chamber of completed cases.Then introduce combustion gas by air admission hole, carry out homogeneous heating baking by nozzle to submersed nozzle, the flue gas of generation is drained from venthole, and after completing baking, submersed nozzle is taken out in pull-out go-cart, completes whole bake process.
The utility model tool has the following advantages: the baking that 1, once simultaneously can complete many submersed nozzles, very big raising cured effect and baking speed, only mouth of a river temperature can be preheating to more than 1000 DEG C from room temperature with 60 points, improve the baking thermal efficiency 20%, baking time is short, baking radical is many, can meet the requirement connecting and water mouth of a river replacing construction.2, heated submersed nozzle by nozzle, ensure that mouth of a river inside and outside wall heating temperature is even, mouth of a river neck preheating is abundant, the steady intensity enhancing of heat, not easy fracture during use, avoids the generation of molten steel solidification phenomenon, improve the fluency watering steel, avoid affecting slab quality.3, good airproof performance, gas medium consumes low, not only can reduce baking cost, and can reduce environmental pollution.
The utility model structure is simple, reasonable in design, easy to use, saves time, and reduces labor strength, has filled up the blank of this type of apparatus for baking, is worth applying widely.
Accompanying drawing explanation
Fig. 1 is structural representation of the present utility model;
Fig. 2 using state figure of the present utility model.
Detailed description of the invention
As shown in the figure, the utility model is by combining as the go-cart 1 of completed cases and half casing 2 are formed.Go-cart is made up of riser 3 and base plate 4.The support 6 for blocking many submersed nozzles 7 is provided with inside riser 3.The bottom of base plate 4 is provided with wheel 5.The side of half casing 2 and bottom are opening, and its top is provided with the air admission hole 8 communicated with the nozzle 9 on inner chamber top, and bottom is propped by the bracing frame 10 being fixed on side wall lower ends, and lower sidewall has venthole 11.
For the ease of push-and-pull go-cart 1, be provided with the slide rail 12 slided for pulley in go-cart 1 and half casing 1 bottom.Meanwhile, outside the hard plate 3 of go-cart 1, handle 13 is provided with.The outer wall of the hard plate 3 of above-mentioned go-cart 1, base plate 4 and half casing 2 is built into by refractory brick.
