Description
Technical field
The present invention relates to the apparatus for baking of liquid metal vessels jar in a kind of smelter production process, the series ladle baking device that uses in particularly a kind of steel-making, the iron-making production.
Background technology
The ladle baking of prior art substantially still follows the tradition baking pattern in hundreds of years at present.The special-purpose burning things which may cause a fire disaster of ladle is baked to high temperature (about 1150 ℃) from normal temperature; The ladle thermal capacity of 100t molten steel volume is approximately 4.14 * 10
6Kilocalorie, approximately needing 60-100 hour and toast such ladle, burning coal gas produces 39 * 10
6The heat of kilocalorie, 4.14 * 10
6Kilocalorie ÷ 39 * 10
6Kilocalorie * 100% ≈ 10.6%, that is to say has 89% heat not obtain utilizing approximately, having slatterned in vain.
Ladle baking heat energy utilization rate is relevant with the ladle temperature difference with cylinder-packing area and flame---and the amount of heat absorption of ladle lining and cylinder-packing area * temperature difference are in direct ratio, and to serve as a contrast outside conductive heat flow density inversely proportional with ladle.According to above-mentioned principle prior art is analyzed, the temperature difference diminishes when ladle lining surface is baked to high temperature, and the temperature of cylinder-packing surfaces externally and internally ladder strengthens heat flow density and increases, thermal loss maximum at this moment, and the heat energy utilization rate is minimum.At this moment increasing heat preserving and insulating material except that between anti-material of cylinder-packing and involucrum can improve the heat energy utilization rate, effective method is to recycle a large amount of elevated temperature heat air-flows that run off, realize no burning things which may cause a fire disaster baking low temperature ladle, the quantity of its heat energy utilization rate and no burning things which may cause a fire disaster baking ladle is directly proportional.That is: toast two ladle heat energy utilization rates simultaneously and double (about 20-25%), toast three ladles simultaneously, the heat energy utilization rate improves about three times (about 30-35%) ...
In sum, designing a kind of device that the remaining thermal current of baking ladle can be toasted other ladle, is to solve the low technical problem to be solved of baking ladle heat utilization at present.
Summary of the invention
Technical problem to be solved by this invention provides the high series ladle baking device of a kind of heat utilization.
The technical scheme that the present invention solves its technical problem is:
A kind of series ladle baking device, form by roaster and pre-roasting device, described roaster is arranged on the ladle mouth place of baking ladle, be provided with for sealing between the ladle mouth of baking ladle and the roaster, the burner of roaster is made of Gas Pipe and air hose, its air hose is installed in the Gas Pipe, roaster is provided with outlet port, outlet port is connected with the air inlet pipe of pre-roasting device, the air inlet pipe of pre-roasting device is provided with valve, baking the ladle mouth place that device is arranged on the preheating ladle in advance, is that the slit is provided with between the ladle mouth of preheating ladle and the pre-roasting device, at the mouth of pipe place of baking the air inlet pipe of device in advance spout is installed.
The technical scheme that the present invention solves its technical problem can also be:
The described roaster of the present invention is provided with two outlet ports, and one of them outlet port is communicated with the air inlet pipe of the pre-roasting device of preheating ladle, and another outlet port is communicated with the air inlet pipe of the pre-roasting device of another preheating ladle.
The spout of the burner of roaster of the present invention and pre-roasting device is separately positioned on the middle part of roaster and pre-roasting device.
The bocca mouth of the burner of roaster of the present invention up.
The spout mouth of pre-roasting device of the present invention up.
Roaster of the present invention has two contact-making surfaces that mate with the ladle mouth that toasts ladle up and down, roaster respectively be provided with up and down one the baking ladle, be provided with at the middle part of roaster and toast the hot gas path that ladle is communicated with up and down, the burner of roaster around be arranged on hot gas path around and mouth down, the baking ladle and the roaster of roaster bottom seal fully, and outlet port only communicates with the baking ladle on roaster top.
The described roaster of the present invention is provided with two outlet ports, and one of them outlet port is communicated with the air inlet pipe of the pre-roasting device of preheating ladle, and another outlet port is communicated with the air inlet pipe of the pre-roasting device of another preheating ladle.
The spout mouth down of pre-roasting device of the present invention.
The invention has the beneficial effects as follows:
In real work, two to four ladles are toasted simultaneously only with the energy that toasts a ladle in traditional baking pattern, after baked ladle removed, again with the preheating ladle as the direct baking ladle, other ladle of preheating more simultaneously, to toast the energy that ladle consumed only be 1/3rd to 1/4th of traditional mode roaster in circulation like this.So series connection baking low temperature ladle is to have utilized the waste heat of baking high temperature ladle energy-conservation, the technological requirement that is more suitable for slowly heating up than traditional mode, and do not have the little fire of low temperature easily the problem of going out can do the energy with low combustion value furnace gas.
