Abstract
The invention discloses an efficient baking device for submersed nozzles used for a continuous casting tundish. The baking device is formed by a trolley and a half box which form a complete box when being combined together. The trolley is formed by a vertical plate and a bottom plate, a support used for clamping the multiple submersed nozzles is arranged at the inner side of the vertical plate, and wheels are arranged below the bottom plate; one side and the bottom of the half box are opened, an air inlet hole communicated with nozzles on the upper portion of an inner cavity is formed in the upper portion of the half box body, the lower portion is supported by supporting frames fixed to the lower end of the side wall, and an air outlet hole is formed in the lower portion of the side wall. The efficient baking device has the following advantages that the multiple submersed nozzles can be synchronously baked at a time, the baking effect is greatly improved, the baking speed is greatly increased, the temperature of the submersed nozzles can be increased to over 1000 DEG C from room temperature only with 60 min in advance, and the heat efficiency of baking is improved by 20%; as the submersed nozzles are heated through the nozzles, it is ensured that the inner walls and the outer walls of the submersed nozzles are evenly heated, and necks of the submersed nozzles are preheated sufficiently; the seal performance is high, fuel gas consumption is low, the baking cost can be reduced, and environment pollution can be reduced.
Description
One, technical field
The invention belongs to apparatus for baking technical field, be specifically related to a kind of continuous casting production submersed nozzle high-efficient cooking apparat.
Two, 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.
Three, summary of the invention
The object of this invention is to provide a kind of structure simple, reasonable in design, 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 used in the present invention 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.
Tool of the present invention 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.
Structure of the present invention 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.
Four, accompanying drawing explanation
Fig. 1 is structural representation of the present invention;
Fig. 2 using state figure of the present invention.
Five, detailed description of the invention
As shown in the figure, the present invention 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.
