Description
Technical field
The utility model is related to the technical fields of steel tube anneal stove, and in particular to a kind of energy-saving roller-hearth steel pipe annealing
Stove.
Background technology
It is original to be not suitable with using the annealing furnace of gas generator with the iterative method of efforts at environmental protection, using natural
Gas is as the trend that fuel is annealing furnace development, since gas cost is 2.5 times or so of coal, if moved back using traditional
Stove, heating is slow, and thermal loss is big in annealing process, and operating cost further increases.
Invention content
In order to solve the above-mentioned problems in the prior art, the utility model provides a kind of energy-saving roller-hearth steel pipe
Annealing furnace.
To achieve the above object, the technical scheme adopted by the utility model is that：
A kind of energy-saving roller-hearth steel pipe annealing furnace, including furnace body, the feed inlet set on furnace body both ends, discharge port, it is described
Furnace body in be equipped with roller-way, furnace body from feed inlet toward discharge port direction be divided into preheating chamber, heating room, equal hot cell, cooling chamber,
Heating is indoor to be equipped with several heating tubes, and burner is equipped at the top of heating tube, and heating tube connects gas delivering pipe and combustion-aid air pipe,
Combustion-aid air pipe is connected at cooling indoor heat exchanger, and heat exchanger connects combustion fan.
Preferably, further including circulating fan, circulating fan connects cooling chamber by air intake duct, is connected by snorkel pre-
Hot cell.
Preferably, the furnace body inner top and side wall are equipped with the alumina silicate needle punched blanket that thickness is 400mm.
Preferably, the bottom of furnace body is equipped with the alumina silicate needle punched blanket that thickness is 200mm, the alumina silicate of bottom of furnace body
Cladding thickness is the alumina silicate thermal insulation board of 20mm on needle punched blanket.
Preferably, being uniformly provided with feeding roller on the roller-way, roller-way both sides are equipped with guardrail, and steel pipe is avoided to convey
Equipment in roller-way or impingement oven is skidded off in the process.
Preferably, the guardrail is the stainless steel plate of thickness 6mm, height 20cm.
Preferably, the combustion-aid air pipe is equipped with check valve, prevent natural gas from flowing into combustion-aid air pipe.
A kind of energy-saving roller-hearth steel pipe annealing furnace described in the utility model, compensates for the deficiencies in the prior art, in stove
Equipped with alumina silicate needle punched blanket, reinforces heat insulation effect, alumina silicate thermal insulation board is covered on the alumina silicate needle punched blanket of bottom of furnace body, convenient for clear
The oxide skin fallen down when steel tube anneal is managed, equal hot cell ensures that temperature of steel pipe is uniform, and the waste heat of cooling chamber is sent by circulating fan
Preheating chamber reduces thermal loss, and the air of combustion fan blowout is used for natural gas combustion-supporting after heat exchanger preheating, while to steel
Pipe is cooled down, and is killed two birds with one stone.
