Abstract
The utility model relates to a metallurgical ladle inverted baking device, and is applied to the baking of various molten metal ladles (steel ladles, molten iron ladles, and non-ferrous metal ladles) in metallurgical plants, and is characterized in that the metallurgical ladle inverted baking device has a sealed high-temperature baking system for the inverted metallurgical ladle, a unique ignition method, and a smoke discharging method. The ladle is inverted to heated and baked in the high temperature. Waste flue gas, preheated air, coal gas, and the metallurgical ladle which is finally preheated for baking form a complete secondary baking system. The baking system effectively and farthest utilizes heat. The utility model is an energy-saving device, and is beneficial to energy saving, and consumption reducing.
Description
The utility model is a kind of metallurgical bale inverted burning-off device, is applicable to the baking of bag of metallurgical works liquid metal.
The baking of metallurgical bag is indispensable in the modern metallurgical production, is an extremely important ring.As everyone knows, the new metallurgy bag of making, contain moisture content in its inner lining refractory, in case use liquid metal and refractory material to work, the steam pressure that the moisture content in the refractory material just can be subjected to produce behind the high temperature causes that refractory material bursts and enters in the liquid metal, causes that hydrogen-oxygen content and impurity content increase in the liquid metals, affect the liquid metal quality, affect up to standardly, impact safety in production affects the raising of benefit.Here it is metallurgical bag why before use must heated baking reason.For the metallurgy bag that makes new making meets instructions for use and for the raising of liquid metal quality creates favorable conditions, must carry out effective heated baking to the metallurgy bag, this device provides reliable assurance for this effective baking.Facts have proved that the baking of metallurgy bag is good, help prolonging and wrap age, improve the quality, save thermal source, increase the benefit.
The baking of the existing normally used metallurgical bag of metallurgical works has two kinds, and a kind of for erecting baking, another kind of is the side baking.Perpendicular baking is to wrap mouth up, coal gas burner stretches in the bag, the coal gas of some burner ejection toasts the metallurgy bag, and perpendicular baking can be divided into two kinds again, and wherein a kind of toasts for open type, it is except the gas pipe of band burner, do not need any miscellaneous equipment, another kind is semi-enclosed baking, promptly adds a top cover above the bag mouth, because the needs of smoke evacuation leave bigger space between top cover and the bag mouth.For the side baking, namely the molten metal bag is toasted from the position reversing an angle of 90 degrees of erectting, its roasting mode is identical with perpendicular baking, immediate boiling baking and semi-enclosed baking, for baking quality is made moderate progress, the employing that has in the bake process, the method that the metallurgy bag is rotated.Its shortcoming is dried by the fire in aforesaid perpendicular baking and side: (1) unsealing or sealing are poor, serious heat loss, and the thermal efficiency is low; (2) gas using quantity is big, and stoving time is long; (3) baking temperature is inhomogeneous, and is of poor quality, and service life is short, increases refractory consumption rate; (4) waste heat is not used, and influences working environment and surrounding environment.
The purpose of this utility model is to be added on improvement for the deficiencies in the prior art part, a kind of metallurgical bale inverted burning-off device is provided, metallurgical bale inverted burning-off device after the improvement is that a kind of metallurgical bag carries out the secondary apparatus for baking that low temperature gives heat and carries out high temperature inversion baking, according to the metallurgical works requirement, this device carries out earlier low temperature to the metallurgy bag and gives heat.Carry out high temperature then and be inverted heated baking, received satisfied effect.
Main points of the present utility model are that metallurgical bale inverted burning-off device comprises: be inverted metallurgical bag, and exhaust smoke hole, flame burner nozzle, high-pressure injection formula burner, Air preheater, coal gas give hot device, high temperature draught fan, the guide type swivel nozzle waits to give the metallurgical bag of heat.Said modules forms complete inversion apparatus for baking system by the baking flow process.Be inverted metallurgical bag and place on the workbench, the refractory fibre medium contact on the deadweight of dependence steamed stuffed bun, steamed stuffed bun and the platform in the dovetail groove forms hermetically sealed.Flame burner nozzle places on the workbench, and burner up, and is straight with the bag dolly, the other end of burner connects with gas piping and air duct respectively, after jet and air switch unlatching, utilize the high-pressure injection burning to chew the coal gas of flame burner nozzle ejection is lighted, steamed stuffed bun is effectively toasted.According to the selected burner quantity of the size of metallurgy bag, be advisable for general 1～6.Exhaust smoke hole places on the workbench, and its effect is to get rid of the waste gas after the gas combustion in the bag.For making in the bag temperature even, do not produce bias current and holding property of flame is unaffected, the burner quantity that exhaust smoke hole quantity is determined according to the steamed stuffed bun size is generally each burner and joins 2～4.In order to make combustion flame normal, cured effect is good, and operation is convenient, and exhaust smoke hole need be higher than flame burner nozzle, and stretches into 400～500mm in the bag.Air preheater and coal gas give the high-temp waste gas of discharging by exhaust smoke hole of finishing that hot device gives respectively hot-air and its task of coal gas and give hot device by pipeline flow-direction and realize, and air, coal gas give the baking that heat is conducive to be inverted metallurgical bag.High temperature draught fan will arrive that coal gas gives hot device, the useless flue gas machinery that gives behind the heating gas is extracted pressurization out, improve pressure head, make its flow direction give hot ladle.The guide type swivel nozzle, sprays at a high speed and waits to give the metallurgical bag of heat after remaining useless flue gas rotation with uniform temperature, the acceleration after the high temperature draught fan pressurization.
The normally used metallurgical bag apparatus for baking of the utility model and existing metallurgical works relatively, have baking evenly, baking quality is good, bag long advantage in age, has simultaneously good airproof performance, the advantage that heat loss is few, the thermal efficiency is high, baking cycle is short, steamed stuffed bun is inverted the waste gas of discharging behind the high-temperature baking and can be effectively utilized, available it give hot-air, coal gas and the metallurgy bag of waiting to give heat, improve working environment, cut down the consumption of energy, increase economic efficiency.Be compared with existing technology, can shorten baking cycle more than 20 hours, gas saving improves and wraps age more than 12% more than 40%.This device is applicable to baking various ladle, ladle and non-ferrous metal liquid body and function bag, and is of many uses.
