Description
Technical field
The present invention relates to a kind of stainless steel continuous annealing apparatus, particularly a kind ofly adopt the vertical without horse not stainless steel continuous annealing furnace of combustion heating mode.
Background technology
Stainless steel clean annealing plate is widely used due to the light had as good solidity to corrosion and minute surface, and stainless steel clean annealing plate adopts stainless steel bright continuous annealing equipment carry out anneal to stainless steel plate and obtain.The stainless steel bright continuous annealing equipment of existing employing combustion heating mode generally adopts direct combustion horse not annealing furnace; namely horse not adopts direct flaming mode to add the body of heater of heat-seal in outside; be connected with protective atmosphere in body of heater, heat radiation is carried out heat treated to Stainless Steel Band by body of heater again.Due to horse not the life-span shorter, General Life in 6 ~ December, when body of heater cracking, just need carry out large repairs to whole stove; Also due to horse size restriction not, general annealing Stainless Steel Band overall dimension is between 600 ~ 800mm.But existingly adopting stainless steel bright continuous annealing equipment without horse not structure to only have Electric heating, single furnace output is also lower.
Summary of the invention
The invention provides a kind of stainless steel continuous annealing apparatus adopting combustion heating mode, annealing furnace times between overhauls is extended, body of heater is widened simultaneously, improve single furnace output, reduce fuel consumption.
For achieving the above object, the present invention takes following technical scheme:
Vertically comprising body of heater without horse not stainless steel continuous annealing furnace, being provided with for transmitting stainless steel plate and the furnace roller be interspersed in described body of heater, the stainless steel plate both sides of transmitting along furnace roller are provided with radiator tube; One end of radiator tube is provided with exhanst gas outlet, the other end of radiator tube be provided with igniting and burner on duty with main burner and the two be communicated with, igniting and burner on duty and burner fuel inlet on duty, burner wind inlet on duty is corresponding is communicated with, main burner and main fuel inlet communication; Body of heater is provided with protective gas entrance and protective gas outlet.
The principle of work of above-mentioned annealing furnace: pass into protective gas from protective gas entrance and flow out from protective gas outlet thus form protective atmosphere in the enclosed space formed at body of heater.Stainless steel plate in Stainless Steel Band entrance input body of heater through furnace roller tensioning and tumbling action along furnace roller transmission.Fuel needed for main burner burning and combustion air are inputted by main fuel import and wind inlet respectively, igniting and the fuel needed for burner on duty igniting and combustion air are inputted by burner fuel inlet on duty and burner wind inlet on duty respectively, complete ignition process and keep the flame of little torch not extinguish under the torch effect on duty of igniting and burner on duty, thus the main burner that ignites, whole radiator tube is full of under the reverse air effect that the heat that main burner burned flame produces inputs at wind inlet, by radiator tube, heat radiation is carried out anneal to stainless steel plate again, stainless steel plate after annealing exports through Stainless Steel Band outlet again.
In order to avoid combustion air temperature low and make fuel can not Thorough combustion occur over-emitting black exhaust phenomenon, at exhanst gas outlet one end built-in heat exchanger of radiator tube, interchanger is communicated with air preheater through valve respectively by wind inlet, exhanst gas outlet, combustion air enters main burner through air preheater input heat exchanger, the high-temperature flue gas that main burner combustion produces improves heat utilization factor further by interchanger and air preheater again, improves combustion air temperature; Valve can also be provided with at main fuel import, burner fuel inlet on duty and burner wind inlet place on duty, close all valves when individual radiation tracheal rupture and make the impact of furnace atmosphere very little, also can continue normal work without the need to changing radiator tube.
As the optimal way of heat exchange between radiator tube and stainless steel plate, radiator tube can be W type pipe, also can be any one in P type pipe, U-tube, double-P type pipe, T-shaped pipe, O type pipe, thimble tube and straight tube, and radiator tube is arranged in parallel with the stainless steel plate transmitted along furnace roller, and more preferably radiator tube vertically arranges with the stainless steel plate transmitted along furnace roller.When stainless steel plate is through furnace roller, because radiator tube is between the stainless steel plate along each furnace roller both sides, makes stainless steel plate successively can be radiated heat through the both sides of this furnace roller, thus stainless steel plate is improved the RADIATION ANGLE COEFFICIENT of radiator tube, radiant heat efficiency improves, more energy-conservation; Adopt furnace roller to transmit stainless steel plate, furnace roller is arranged along the width of body of heater, and use wider furnace roller that body of heater correspondingly can be made also wider, therefore treatable stainless steel plate width greatly increases and improves stainless steel plate processing power; In addition, the stainless steel plate of several pieces of small dimensions can also be processed, as long as overall size is no more than the width license of body of heater simultaneously.
Above-mentioned vertical without horse not stainless steel continuous annealing furnace have horse not compared with stainless steel annealing stove with common; body of heater also can form an enclosed space; protective gas is passed into from protective gas entrance; protective atmosphere is formed in enclosed space; can with having retort furnace equally for stainless steel continuous annealing provides suitable atmosphere; owing to not having horse not, without the need to more changing person not.
Above-mentioned vertical without horse not stainless steel continuous annealing furnace with other without compared with horse not stainless steel electric annealing furnace, adopt radiator tube type of heating, fuel is not in stove, but in radiator tube combustion, the heat of radiator tube obtains by after fuel combustion, can provide more thermal load, and stainless steel processing power is larger, what process is larger, substantially increases single furnace output.
The present invention adopts gas or liquid fuel combustion to provide heat, and fuel not in stove, but in radiator tube combustion, due to without horse not, is also just not changed without horse the annealing furnace overhaul caused, extended by annealing furnace times between overhauls; Body of heater is widened simultaneously, improve single furnace output.
