Description
Technical field
The present invention relates to metallurgical for containing the baking of liquid metal barrel cage, particularly casting and the continuous billet casting baking of ladle tank.
Background technology
The Sheng steel of current foundry industry and steel and iron industry or the barrel cage baking object of iron, make refractory material serve as a contrast the son that dries out, when preventing from containing molten steel or iron liquid, aquation crystal decomposites hydrone suddenly, molten steel or iron liquid and hydrone mixing detonation, demolition refractory masses also promotes molten steel or the splash of iron liquid goes out barrel cage injures and deaths operator.Another object is: if when barrel cage refractory material lining is baked to sufficiently high temperature, absorb physics heat energy entrained by molten steel or iron liquid less when containing molten steel or iron liquid, therefore, can reduce and smelt tapping temperature improving energy efficiency.This special insider knows very well that smelting temperature is that the expensive high-energy energy of burnup obtained, and smelting furnace temperature is the pyramidal pinnacle of enterprise energy consumption, pinnacle consumption reduction pyramid volume-diminished.And barrel cage baking is generally with cheap energy coal gas of converter or blast furnace gas etc., the temperature that the cheap energy that burns can improve baking barrel cage also just quite improves efficiency.
Well-known refractory material is good thermal resistance material, and its heat resistance characteristic restriction rate of heat transfer, therefore can not be rapidly heated! The heat energy of baking burning is necessarily dynamic, so heat energy only rapidly flows through at refractory surface, and the loss that most combustion heat energies is helpless.The problem that the baking equipment of existing steel and iron industry application also has is: the downward flame flow high-temperature part of burner is relative with returning flue gas stream to flow to hitting, bottom barrel cage, quite have an air flow mattress, the strong and weak size of this air flow mattress and the downward flame flow high-temperature part of burner in direct ratio.Flame flow high-temperature part does not arrive bottom in theory, the especially bight of bottom periphery, and bight adjacent wall is the heat transfer heat radiation of bidimensional, and therefore, its amount absorbing heat is approximately multiple.Flame flow high-temperature part can not arrive herein, actual bight mainly radiant heat baking.So the bight of bottom periphery is constant low-temperature space, not only tying down baking process delayed prolongation baking time wastes the considerable energy.And aquation crystal decomposes suddenly when containing steel or iron liquid, steel or iron liquid and hydrone mixing detonation, demolish the accident initial point that resistance to material or promotion steel or the splash of iron liquid have a barrel cage injures and deaths operator and be also this.
Prior art, a kind of stretch-in ladle heat exchange roasting nozzle ZL201010199160.5 it is said: it is fixed with " U " type radiant body in the bottom of steel ladle cover, multiple combustion air playpipe be communicated with structural tube is distributed with around the structural tube of " U " type radiant body, structural tube is communicated with the combustion-supporting wind regime of pressure by combustion air pipeline, the emitted dose of combustion air playpipe is mated with the emitted dose of gas-jet tube and injection direction all points to and wraps the end and indentured intersection, forced burning heat energy arrives the bight of intersection, improve heat utilization rate significantly, well solve the Low Temperature Problems of bight bidimensional heat radiation heat transfer.But a kind of defect of stretch-in ladle heat exchange roasting nozzle is also obvious, " U " type radiant body is that fragility refractory material volume is excessive, manufacture the difficulty life-span low, manufacturing cost is certain also very high, and excessive " U " type radiant body of volume also takies heat energy, have the high defect that should not promote the use of of cost, causing stretch-in ladle heat exchange roasting nozzle to be invented over 5 years does not have successful implementation to apply.
It is said that connection apparatus for baking ZL:200910120000.4 altered by another kind of ladle, described: to be made up of roaster and pre-baked device, described roaster is arranged on the ladle mouth place of baking ladle, arrange for sealing between the ladle mouth of baking ladle and roaster, the burner of roaster is made up of Gas Pipe and air hose, its air hose is installed in Gas Pipe, roaster is provided with outlet port, outlet port is connected with the air inlet pipe of pre-baked device, the air inlet pipe of pre-baked device is provided with valve, pre-baked device is arranged on the ladle mouth place of preheating ladle, for gap is arranged between the ladle mouth of preheating ladle and pre-baked device ... burner is around being arranged on the surrounding of hot gas path and mouth down ....Its heat utilization rate improves three times than original ladle baking, and the baking of original ladle baking that this article is recorded and ladle tank of the present invention, its heat utilization rate, about 10.6%, improves three times on this basis, and the present invention finds that this measuring and calculating is wrong.The present invention sends out the results of measuring different from it:
As.The ladle of 100t need build about 10000Kg refractory material by laying bricks or stones, and the 100t ladle of newly building by laying bricks or stones needs baking 80-100 hour ability to use, and baking average minute clock burns about 4.5m
3calorific value is 9196KJ/m
3combustion gas coal gas of converter, need burn about 21600m altogether
3combustion gas, 21600m
3combustion gas is roughly equal to 198635600kJ heat energy, closes 6777.7Kg and marks coal.
The ladle of 10000kg refractory material, inner surface is baked to 1050 DEG C, ladle, and outer surface reaches 200-270 DEG C of available standard, and now, the specific heat capacity of refractory material selects 0.74kJ/kg measuring and calculating:
0.74kJ/kg × 10000kg × 1050 DEG C-235 DEG C of ÷ 2=3015500kJ heat energy.
3015500kJ heat energy closes mark coal:
3015500kJ/29307kJ/kg marks coal=102.9kg and marks coal.
102.9kg mark coal/6777.7Kg marks the heat utilization rate of coal × 100% ≈ 1.51%.
Measuring and calculating error described in obvious a kind of series ladle baking device is close to ten times, and described heat utilization rate improves three times, really has significant progress, but.If only reach 4.5% only by measuring and calculating of the present invention, the heat energy of 95.5% is in fact also had not utilized.Reason is refractory material better heat resistance characteristic restriction rate of heat transfer, causes the energy heat energy of a large amount of baking burning only to flow through at refractory surface, the loss that most dynamic heat energy of burning is helpless.The heat energy favorable attributes run off is only maintain the conduction that thermograde supports heat energy.
Barrel cage baking form is similar to the geometric shape of IC engine cylinder body running, but internal combustion engine thermal efficiency is the ratio that burning capacity and mechanical energy export, and the thermal efficiency that barrel cage toasts to be combustion heat energy and fire proofed wood serve as a contrast occupies ratio.Relatively, obviously deepen the understanding to barrel cage baking thermal efficiency characteristics, both geometric similarity physics are different; Effective heat energy of barrel cage baking burning absorbs the minimum part heat energy of accumulation just like internal combustion engine reactance capacity part cylinder body.In sum, most heat energy barrel cage bodies of barrel cage baking burning cannot make full use of, and therefore, the overwhelming majority of the barrel cage baking combustion heat is waste heat, and its waste heat recycling is the approach the most effectively improving the thermal efficiency.In order to economize energy, improving the high-temperature baking temperature of barrel cage, can improve resistance to material rate of heat transfer and thermal effect, can reduce again furnace temperature and save the expensive energy, is the effective way reducing production cost.
