Description
Technical field
The present invention relates to industrial heating furnace, especially a kind ofly prevent walking the efficient stepping-bottom-type heater for rolling steel of bias tyre.
Background technology
Traditional stepped start-stop system heater for rolling steel is delivered on the feeding skid before step heating-furnace by crane according to processing requirement steel billet, round steel at feeding skid is ploughed under on furnace roller road by turn-down rig, need when filling with substance, entering furnace roller road starts to start blank is served to charging hanging arm roll, blank is delivered in stove by charging hanging arm roll, after being located by locating device according to the length of blank, charging hanging arm roll is out of service, dump bottom is by the fixing end in round steel holder, the regular-shape motion of the steel billet heating in stove at the bottom of by stepping delivered to tapping side from entering furnace side, steel billet is successively by the preheating section of process furnace, heat one section, heat two sections and soaking zone, and fully heated, the blank heating is put on the interior discharging cantilever of stove road, discharging cantilever road is sent round steel outside stove.The problem that existing stepped start-stop system heater for rolling steel exists is:
1. body of heater length, generally at 10 meters-20 meters, because blank in the error stove of building is easily offset to one side furnace wall all the time when translation is advanced, causes steel billet in stove to wipe furnace wall, production development fault, so that blowing out stops production.
2. at whole furnace bottom, there is a circle water sealed tank, water sealed tank is fixed on the large frame of activity bottom of boiler machinery, water in water sealed tank need to keep little water overflow and temperature constant state, and discharging each time all needs blank motion in the whole furnace bottom of furnace bottom actuator drives, water sealed tank, water and stove.Activity bottom of boiler is heavier, and furnace bottom rocks the hot water that easily causes in water sealed tank and clash into and overflow, and whole driving wastes energy, and easily worsens environment.
3. traditional burner decoration form is that preheating section is not arranged burner, heat one section, heating two sections of burner power increase successively, soaking zone burner power is lower slightly.This burner decoration form, has following shortcoming: rate of heating is slower, and productivity is lower, and oxidization burning loss is more.
Summary of the invention
The object of the invention is to solve the above-mentioned three aspects: problem that existing stepped start-stop system heater for rolling steel exists, a kind of efficient stepping-bottom-type heater for rolling steel of bias tyre of preventing walking is provided.
Concrete scheme of the present invention is: for existing stepped start-stop system heater for rolling steel, improve, it has body of heater, charging hanging arm roll and discharging cantilever road are equipped with respectively in the turnover two ends of body of heater, the both sides of body of heater are positioned at one section of heating, on two sections and soaking zone, some burners are all installed, in the bottom of body of heater, be provided with the fixedly end and movable blade, fixedly on the relative edge of the end and dump bottom, dead knife and movable blade are housed respectively, two cuttves are furnished with water sealed tank and form water seal arrangement, column at the bottom of fixing beneath side is equipped with along length to two grate furnaces of arranging, the top of furnace bottom column is equipped with joist steel and is withstood the fixedly end, below dump bottom, furnace bottom stepping transmission mechanism is being installed between column at the bottom of two grate furnaces, drive dump bottom, it is characterized in that: a. is provided with aligning gear on a sidewall of the easy offset direction of blank of body of heater, the push rod of aligning gear is arranged over against blank, b. described water sealed tank is to be fixedly equipped with on furnace bottom column by some cantilever levers, and the lower end of dead knife and movable blade is stretched into water sealed tank and added water-lute.
The oil cylinder of centering described in the present invention is to be positioned in the front end side wall of one section of body of heater heating to arrange.
Three sections of burner power that are arranged on described in the present invention on one section of body of heater heating, two sections of heating, soaking zone distributed by 5: 3: 2, and three segment length account for 2/3rds of body of heater total length.
The present invention has the following advantages:
1. the present invention has set up aligning gear, has blank bias correcting function.Suppose that blank position is 120 in stove, suppose that the walk deviator of blank when every row is further is 2mm, covering total deviator of walking after all material levels is 240mm, causes blank wiping furnace wall and stopping production blowing out.The present invention is mainly by aligning gear, after can realizing in stove, in blank traveling process, skew to a certain degree occurring, blank position is corrected placed in the middle, thereby prevent that blank skew from causing wiping wall.
2. the present invention improves the installation form of furnace bottom water sealed tank, water sealed tank is fixed on furnace bottom column, change movable for fixed, during stove work, dump bottom motion, movable blade is followed translation up-and-down movement, water sealed tank maintains static, thereby avoided the water of original water sealed tank to rock and overflow because of translation, reduced again the load of furnace bottom driving device simultaneously, reduced consumption and the rate of breakdown of electric energy.
3. the present invention is at full stove for design improvement in ratio of specific heat, and this design is more conducive to realize cold base and enters the heat of forcing after stove, thereby reach, shortens heat-up time, boosts productivity, and reduces energy consumption and oxidization burning loss.
