Abstract
The invention discloses a drying technology for a novel firebrick structure chamber-type forging heating furnace, and relates to the technical field of forging heating furnace drying. The drying technology comprises the following steps: (1), carrying out heating to reach 200 DEG C plus or minus 20 DEG C, preserving heat for 6 hours, cooling to room temperature, and then repeatedly carrying out heating and cooling for 5-6 times altogether; (2), carrying out heating to reach 600 DEG C plus or minus 20 DEG C, preserving heat for 6 hours, cooling to room temperature, and then repeatedly carrying out heating and cooling for 4 times altogether; (3), carrying out heating to reach 900 DEG C plus or minus 20 DEG C, preserving heat for 6 hours, cooling to room temperature, and then repeatedly heating and cooling for 4 times altogether; (4), carrying out heating to reach 1200 DEG C plus or minus 20 DEG C, preserving heat for 6 hours, cooling to room temperature , and then repeatedly carrying out heating and cooling for 4 times altogether. Through repeated heating and cooling, and drying of the furnace through staged heating, not only the structure of a furnace hearth is protected so as to prevent brick cracking, but also the furnace drying time is shortened and fuel is saved.
Description
Technical field
The present invention relates to forge furnace furnace technology field, be specifically related to a kind of new-type firebrick structure chamber-type forge furnace roast technic.
Background technology
Forge furnace heating-up temperature up to 1250 DEG C, after firebrick structure chamber-type forge furnace puzzles, if be directly heated to 1250 DEG C, body of heater thermal stress is excessive, and there is moisture brick body inside again, becomes steam under high temperature, add syphon body internal stress, very easily cause brick body, body of heater to ftracture.When after brick body cracking, heat will reach the insulating brick-layer 1 shown in Fig. 1 from burner hearth, causes insulating brick-layer 1 to melt, and body of heater lost efficacy.Existing furnace technology is long-time heat preservation stage by stage for this reason, and technique as shown in Figure 2.This technique heat time is long, and fuel consumption is large, and long-time heating is incubated, and burner hearth pressure-fired, in brick body, moisture can only be discharged to exterior wall.Due to the heat insulation effect of heating furnace, when fire box temperature is to 1250 DEG C, temperature≤50 DEG C of exterior wall steel plate 2.Therefore no matter baker temperature retention time is long again, is also difficult to the water in insulating brick-layer 1 all to be removed.If when Fast Heating after heating furnace baker a period of time, body of heater is very easily caused to ftracture.
Summary of the invention
The object of this invention is to provide a kind of new-type firebrick structure chamber-type forge furnace roast technic; it can solve, and firebrick structure chamber-type forge furnace furnace drying time is long, fuel consumption large, halfway problem of anhydrating; by repeatedly heating cooling; and the baker that progressively heats up stage by stage; both chamber structure was protected; prevent brick body from ftractureing, shorten furnace drying time again, save fuel.
In order to solve the problem existing for background technology, the present invention is by the following technical solutions: its roast technic is: (1), be heated to 200 DEG C ± 20 DEG C insulations 6 hours, is cooled to normal temperature, then heating cooling totally 5 ~ 6 times repeatedly; (2), be heated to 600 DEG C ± 20 DEG C insulations 6 hours, be cooled to normal temperature, then heating cool totally 4 times repeatedly; (3), be heated to 900 DEG C ± 20 DEG C insulations 6 hours, be cooled to normal temperature, then heating cool totally 4 times repeatedly; (4), be heated to 1200 DEG C ± 20 DEG C insulations 6 hours, be cooled to normal temperature, then heating cool totally 4 times repeatedly.
Principle of the present invention is: pressure-fired when utilizing heating and thermal insulation, negative pressure during cooling, inner and outside is got rid of respectively by steam, compared with former roast technic, reach and accelerate to get rid of steam object from burner hearth.Owing to adopting the baker that progressively heats up stage by stage, protect chamber structure, prevent brick body to ftracture.
The present invention can solve that firebrick structure chamber-type forge furnace furnace drying time is long, fuel consumption is large, halfway problem of anhydrating, by repeatedly heating cooling, and the baker that progressively heats up stage by stage; both chamber structure was protected; prevent brick body from ftractureing, shorten furnace drying time again, save fuel.

Detailed description of the invention:
With reference to Fig. 3, this detailed description of the invention by the following technical solutions: its roast technic is: (1), be heated to 200 DEG C ± 20 DEG C insulations 6 hours, is cooled to normal temperature, then heating cooling totally 5 ~ 6 times repeatedly; (2), be heated to 600 DEG C ± 20 DEG C insulations 6 hours, be cooled to normal temperature, then heating cool totally 4 times repeatedly; (3), be heated to 900 DEG C ± 20 DEG C insulations 6 hours, be cooled to normal temperature, then heating cool totally 4 times repeatedly; (4), be heated to 1200 DEG C ± 20 DEG C insulations 6 hours, be cooled to normal temperature, then heating cool totally 4 times repeatedly.
The principle of this detailed description of the invention is: pressure-fired when utilizing heating and thermal insulation, negative pressure during cooling, inner and outside is got rid of respectively by steam, compared with former roast technic, reach and accelerate to get rid of steam object from burner hearth.Owing to adopting the baker that progressively heats up stage by stage, protect chamber structure, prevent brick body to ftracture.
This detailed description of the invention can solve that firebrick structure chamber-type forge furnace furnace drying time is long, fuel consumption is large, halfway problem of anhydrating; by repeatedly heating cooling; and the baker that progressively heats up stage by stage; both chamber structure was protected; prevent brick body from ftractureing; shorten furnace drying time again, save fuel.
