Description
Technical field:
The utility model relates to a kind of hybrid middle water containing opening apparatus for baking, belongs to the smelting iron and steel technical field.
Technical background:
Existing middle water containing opening apparatus for baking, corresponding each mouth of a river, all corresponding independent apparatus for baking, its roasting mode is the gas-fired formula.When tundish came into operation preceding two hours, by operating personnel mouth of a river roaster is placed into corresponding burner bottom, connect after the gaspipe line, the valve that turns on the gas-fire, the some burner carries out mouth of a river baking.This apparatus for baking has the following disadvantages: A: mouth of a river cured effect is poor, is difficult to satisfy the requirement of reaching the standard grade.Under multiple factor affecting such as gas pressure, flow, composition, mouth of a river baking temperature generally is up to about 700 degree, be difficult to reach the above requirement of 800 degree, and temperature field, mouth of a river distributed pole is inhomogeneous, often is easy to generate when putting into production to burst.B: stoving time is long.Because independent coal gas baking speed is slow, mouth of a river baking temperature promotes slow, so stoving time was not less than 2 hours.C: energy medium is single, can not fully burn, and waste is serious.The spontaneous firing in air of a large amount of coal gas can't fully be burnt, and causes gas utilization rate low, and energy waste is serious.D: produce and be subjected to the restriction of coal gas factor seriously.Low at gas pressure, flow is little, when perhaps coal gas proportioning components calorific value is low, when the mouth of a river can't be satisfied minimum baking and required, is difficult to guarantee normal rhythm of production.E: manipulate complex steps.Before each baking, be hinged with pipeline, the fixed position, complex steps such as frequent adjustment height have increased labor strength.
CN2225324 discloses a kind of apparatus for baking of middle water containing opening of continuous casting steel, it comprises burns head and air inlet pipe, be provided with the mixing chamber shell in the bottom of burning head, one side of burning the head below is provided with lighting-up tuyere, burn in the head and be provided with the combustion chamber, the interior mixing chamber of combustion chamber and mixing chamber shell communicates, and the lower end of mixing chamber shell is provided with two air inlet pipe, be respectively equipped with valve on two air inlet pipe, the shell and the elevating mechanism that burn head join.
CN1565772 discloses a kind of steelmaking equipment apparatus for baking and baking method, particularly a kind of apparatus for baking and baking method of continuous casting tundish submersed nozzle.Solved existing mouth of a river apparatus for baking cured effect defect of bad.Technical scheme is: the apparatus for baking and the baking method of bag submersed nozzle in a kind of continuous casting, comprise roaster, submersed nozzle, filling pipe end, submersed nozzle stretches into the roaster inner chamber, flexible sealing shroud is installed between roaster and the submersed nozzle, the external breather pipe in hole is opened in the roaster bottom, muffler is installed in the breather pipe end, drainage tube passes airway wall and enters the breather pipe inner chamber and be partial to muffler one side, and that the present invention has is simple in structure, noise is little, the advantage of easy to use, energy savings.
Summary of the invention:
At the deficiencies in the prior art, the utility model provides a kind of manufacture craft simple, easy to operate, improve the middle water containing opening life-span, reduce secondary oxidation of steel, improve the molten steel recovery rate, stablize slab quality, improve tundish service life, have the hybrid middle water containing opening apparatus for baking of promotion prospect widely.
A kind of hybrid middle water containing opening apparatus for baking, the pipe valve and the pressure that comprise apparatus for baking body, roasting nozzle, each medium are adjusted checkout gear, be characterized in, the apparatus for baking body is provided with the hybrid roasting nozzle of height adjuster and the unification of three gas, roasting nozzle is connected with mixing chamber, and mixing chamber is connected with compressed air line with gaspipe line, propylene pipeline respectively.
Described height adjuster is arranged on below the apparatus for baking body, comprises connecting excessive piece, guide holder and hydraulic jack, connects excessive piece between hydraulic jack and apparatus for baking body, and hydraulic jack withstands between two guide holders.
Described gaspipe line and propylene pipeline are positioned at the mixing chamber both sides, compressed air line is positioned on the bottom surface of mixing chamber, and gaspipe line, propylene pipeline and compressed air line are adjusted checkout gear by metal hose, pipe valve and pressure respectively and be connected with separately source of the gas; Snap joint is all installed at the metal hose two ends.
Reinforce the connection by the stainless steel hard tube between described gaspipe line, propylene pipeline and the compressed air line.
Mixing chamber can at first be realized the abundant mixing of coal gas propylene, finally under the compressed-air actuated promotion in bottom, ejects the flame that heat energy, form etc. satisfy baking condition fully.In addition,,, and control mode such as its output pressure, realize the adjusting of baking flame intensity by adjustment to coal gas, compressed air, three main valve open degree of propylene according to the situation of coal gas medium situations such as (low) calorific value are low as pressure.In addition,, utilize height adjuster, adjust the optimum distance of burner easily to the mouth of a river according to the concrete condition of the mouth of a river and flame.Guarantee to satisfy best cured effect.
The utlity model has following advantage: A: cured effect is good.Owing to adopted coal gas, propylene mist, pressure is big, the calorific value height, realized the full encirclement baking of flame to the mouth of a river, realized that mouth of a river bulk temperature steadily promotes, by test, average temperature rising has improved than originally about 110 degree, satisfy fully the mouth of a river reach the standard grade before preheat temperature be higher than 800 requirements of spending.B: temperature increase is fast.Because mixture pressure is big, the calorific value height, sufficient combustion, baking intensity is big, reaches baking and requires to taper to present 45 minutes by original 2 hours.C: energy utilization rate height.Because stoving time is short, the baking position is moderate, adds compressed air combustion-supporting, has realized the abundant burning and the utilization of medium, greatly reduces energy resource consumption.D: produce and be subjected to coal gas factor constraint reduction.According to the coal gas actual conditions, suitably adjust the propylene flow, realized that based on coal gas propylene is the roasting mode of assisting, no matter the coal gas what state can both satisfy the production needs.E: easy and simple to handle.Owing to carried out the whole integrated form of apparatus for baking, just to have removed support at every turn from and moved, troubles such as pipeline connection as long as middle hired car puts in place, are lighted medium, adjust valve, adjust height, just can realize having toasted smoothly.
Use the utility model to carry out mouth of a river baking, can improve the temperature after the neck preheating of the mouth of a river, can make the temperature field at the mouth of a river mild simultaneously, satisfy the baking requirement of the mouth of a river when producing along the graded of axis direction.It is simple to the utlity model has manufacture craft, easy to operate, improves the middle water containing opening life-span, reduces secondary oxidation of steel, improves the molten steel recovery rate, stablize slab quality, raising tundish service life, has widely characteristics such as promotion prospect.
