Abstract
The utility model relates to the technical field of steel pipe production equipment, in particular to a furnace for steel pipe heat-treatment during the steel pipe production process. The furnace comprises a furnace body, heating pipes and rolling conveyor rollers, wherein the heating pipes are arranged in the furnace body and used for heating steel pipes passing through the interior of the furnace body; the rolling conveyor rollers are arranged at the inner lower part of the furnace body; interlayers are arranged on the inner walls of the furnace body; stack gas outlet pipes which are communicated with a furnace chamber are arranged above the furnace body; and the stack gas outlet pipes are communicated with the interlayers. High temperature stack gas emitted from the heating pipes by heating the steel pipes in the furnace body enters into the interlayers through the stack gas outlet pipes to preserve heat in the furnace chamber to avoid preheating the furnace chamber for the next heat-treatment of the steel pipes, so as to save heating cost, meet the temperature requirements of the steel pipe heat-treatment process, improve the heat-treatment quality of the steel pipes, and ensure performance of the steel pipes.
Description
Technical field
The utility model relates to the steel pipe's production equipment technical field, is specifically related to a kind ofly in the steel pipe's production process, steel pipe is carried out the stove of heat treated.
Background technology
Heat treatment furnace kind used in the smelting iron and steel is more, but the complex structure of most heat treatment furnaces, and big energy-consuming, cost height and efficient are low; Structure like existing steel pipe heat treatment furnace comprises body of heater, is arranged on the intravital heating tube of stove; And be arranged on the rolling conveying roller that carry steel pipe body of heater inside below; Before in steel pipe gets into body of heater, just need carry out heat temperature raising to stove body temperature, thereby also just increase heating cost through heating tube; Improve production cost, guaranteed not the temperature requirement of process for heat treatment of steel pipe simultaneously.
Summary of the invention
To above-mentioned technical problem, the utility model provides a kind of steel pipe heat treatment furnace, and it can be transported to the high-temperature flue gas in the stove in the interlayer; Furnace chamber is incubated; Thereby when steel pipe is heat-treated, just do not need in advance furnace chamber to be carried out preheating, saved heating cost; Guarantee the temperature requirement of process for heat treatment of steel pipe, improved the thermal treatment quality of steel pipe.
The technical scheme that realizes the utility model is following:
The steel pipe heat treatment furnace; Comprise body of heater, be arranged on the heating tube to heating in the body of heater through the intravital steel pipe of stove; And the rolling conveying roller that is arranged on below, body of heater inside; Said inboard wall of furnace body is provided with interlayer, above body of heater, is provided with the many flue gases that are connected with furnace chamber and goes out pipe, and said flue gas goes out pipe and is connected with interlayer.The high-temperature flue gas that heating tube gives out the steel pipe heating goes out pipe through flue gas to get in the interlayer, thereby stove body temperature is preserved, and when steel pipe being heat-treated, just need not in advance to carrying out preheating in the furnace chamber next time.
Said body of heater is provided with the vapor pipe that communicates with furnace sandwich, and the end of vapor pipe connects a filtration unit.Have a lot of dusts towards the interior high-temperature flue gas of interlayer and mix therein, thereby before the high-temperature flue gas in the interlayer being discharged, need filter it through filtration unit again, the gas that assurance gives off meets the requirement of gaseous emission.
Said filtration unit comprises the filtration barrel body that is connected with vapor pipe, in filtration barrel body, is provided with the bed filtration net, and the top of filtration barrel body is provided with smoke outlet.High-temperature flue gas in the interlayer gets in the filtration barrel body, by wherein bed filtration stratum reticulare layer high-temperature flue gas is filtered, thereby guarantees that the smoke outlet expellant gas meets the gaseous emission requirement.
Adopted such scheme, when the intravital steel pipe of entering stove was heat-treated, the high-temperature flue gas that heating tube gives out because of heating went out pipe through flue gas and gets in the interlayer; Furnace chamber is incubated, thereby when steel pipe carries out thermal treatment next time, does not just need in advance furnace chamber to be carried out preheating; Saved heating cost; Guarantee the temperature requirement of process for heat treatment of steel pipe, improved the thermal treatment quality of steel pipe, guaranteed the performance of steel pipe.
Description of drawings
Fig. 1 is the structural representation of the utility model;
Fig. 2 looks synoptic diagram for the right side of Fig. 1;
Among the figure, 1 is body of heater, and 2 is heating tube, and 3 are the rolling conveying roller, and 4 is interlayer, and 5 for flue gas goes out pipe, and 6 is vapor pipe, and 7 is filtration barrel body, and 8 is filtering net, and 9 is smoke outlet.
Embodiment
Below in conjunction with accompanying drawing and specific embodiment the utility model is further specified.
Referring to Fig. 1,2; The steel pipe heat treatment furnace comprises body of heater 1, is arranged on the heating tube 2 to heating through the intravital steel pipe of stove in the body of heater, when heating, in heating tube, adds combustion gas and just can heat the intravital steel pipe of stove; And the rolling conveying roller 3 that is arranged on below, body of heater inside; The rolling conveying roller can be carried the steel pipe that gets into body of heater, again steel pipe through thermal treatment after, rolling conveying roller 3 carries out steel pipe again from furnace chamber; Body of heater two inwalls are provided with interlayer 4, above body of heater, are provided with the many flue gases that are connected with furnace chamber and go out pipe 5, and the high-temperature flue gas in the furnace chamber can go out pipe from flue gas and discharge; Flue gas goes out pipe 5 and is connected with interlayer 4, thereby flue gas goes out in the high-temperature flue gas entering interlayer that pipe discharges, and body of heater is incubated; And body of heater is provided with the vapor pipe 6 that communicates with furnace sandwich; The end of vapor pipe 6 connects a filtration unit; Filtration unit comprises the filtration barrel body 7 that is connected with vapor pipe, in filtration barrel body 7, is provided with bed filtration net 8, and the top of filtration barrel body is provided with smoke outlet 9.The vapor pipe expellant gas is got in the filtration barrel body by the filtration barrel body lower end, filters by 8 pairs of gases of bed filtration net, and be clean from the smoke outlet expellant gas, satisfy the gaseous emission requirement fully.
