Description
Technical field
The utility model belongs to the technical field of stuffing sand roasting plant, specially a kind of stuffing sand roaster, is applied to
The baking of stuffing sand used in the great Bao hot repairs workshop section of all electric furnaces, BOF steelmaking shop at present, when the set temperature is reached, from
It is dynamic to shut down insulation, safety, energy-saving and environmental protection.
Background technology
Steel-making level is constantly improving at present, to reduce the oxygen content in steel, is sealed by original unlimited cast towards complete
Close direction to develop, therefore many steel mills propose big bag self-opening rate requirement almost very.
Stuffing sand is to be filled in the big refractory material wrapped in the mouth of a river and upper slide plug hole, and it is got well with badly directly affecting
The self-opening rate wrapped greatly, judging from the current situation, it is exactly the exceeded of moisture content to influence the most uncertain factor of big bag self-opening rate, restricted
Larger in the factor of environment, especially summer and coastal area is more obvious.Stuffing sand roaster can be removed effectively in stuffing sand
Moisture content, and environmental protection, energy-conservation.
With the development of furnace outer refining technology, more and more higher is required to big bag self-opening rate, stuffing sand is in more stringent bar
Worked under part, such as can not naturally open and pour, worker has to blow the mouth of a river with oxygen lance boiled, and help, which is opened, pours.Big bag not from opening and
Carry out burning eye operation and have many problems appearance, be the personal safety of worker first, next to that the molten steel oxidation that oxygen blast is brought, very
The nonmetal inclusion of strand may extremely be caused.Found through experiment, when water content is more than 0.5% in stuffing sand, cause not open certainly
Probability at least rise to 85%, therefore many steel mills employ the stir-frying of heated by gas hopper or directly insert gas pipe and drain
The method toasted in sand to it, although there is good effect to removing moisture content, but these method energy consumptions are big, just in case coal gas goes out
Fire can cause the generation of personal coal gas injury accident, therefore design this stuffing sand Special Baking device.
The content of the invention
The utility model is in order to solve because water content is exceeded to be unfavorable in stuffing sand from opening and existing with regard in technology
Using the energy consumption of coal gas stir-frying mode etc. is big and security hidden trouble, a kind of stuffing sand roaster is designed, can using electrical heating case
Temperature height is adjusted, can automatic heat preserving.
The technical solution of the utility model is：
A kind of stuffing sand roaster, it is characterised in that including baking rack, roaster body is fixed on baking rack, the baking
The sidewall paneling that roasting device body includes baking bottom plate and is fixed on baking bottom plate, roaster body is opened type structure, described
Baking bottom plate include lower shoe, upper plate and fin electric heating tube, between fin electric heating tube and lower shoe, sidewall paneling
Space in be filled with heat-preservation cotton, temperature thermocouple is set between fin electric heating tube；Described fin electric heating tube passes through
Conductive electric wire is connected to contactor, and contactor is electrically connected to power supply；Temperature thermocouple is wired to temperature controller, temperature controller electricity
It is connected to contactor.
The characteristics of the utility model, also has：
Described fin electric heating tube places 4-8 roots.
Drain hole is set on sidewall paneling.
Blowing mouth structure uses the board plug structure coordinated with sidewall paneling, and handle is set on plate.
Described roaster body is duplex assembling structure.
Described temperature controller and contactor is placed in electric cabinet.
Stuffing sand roaster of the present utility model is powered with fin electric heating tube and heated up, temperature thermocouple data transfer
To temperature controller, when temperature reaches the temperature upper limit of temperature controller setting, stop section or the work of whole finned tubes, into insulation rank
Section, when temperature drops to the lower limit of setting, fin electric heating tube, which is all powered, enters the temperature rise period.In fin electric heating tube with
Heat-preservation cotton is filled with space between bottom plate, sidewall paneling, i.e., heat-preservation cotton is not set between fin electric heating tube and upper plate,
Using heat-preservation cotton filling insulation, energy resource consumption is saved to greatest extent in its excess-three side.
The beneficial effects of the utility model are：
The utility model replaces original gas toast using green energy resource, reduces environmental pollution and ensure that worker's
Safety, when the temperature for reaching setting, can be automatically stopped operation, save the energy, due to using Automatic Control, being shone without people
See, reduce the expenditure of personal expenditures, there is certain social benefit.The dry of stuffing sand can be effectively ensured in use of the present utility model
It is dry, ladle self-opening rate is improved, there is bigger economic benefit and social benefit.
