Technical field
The utility model relates to industrial heating furnace, especially a kind ofly prevents 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 feeding skid before step heating-furnace by crane according to the processing requirement steel billet, the round steel of feeding skid is ploughed under the furnace roller road by turn-down rig on, need when filling with substance, entering the furnace roller road begins to start blank is served the charging hanging arm roll, blank is delivered in stove by the charging hanging arm roll, after being located by locating device according to the length of blank, the charging hanging arm roll is out of service, dump bottom is with the fixing end in the round steel holder, the regular-shape motion of the steel billet that heats in stove at the bottom of by stepping delivered to the tapping side from entering the furnace side, steel billet is the preheating section by process furnace successively, heat one section, heat two sections and soaking zone, and fully heated, the blank that heats is put in stove on the discharging cantilever road, the 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 is generally at 10 meters-20 meters, because blank in the error stove of building easily is offset to one side furnace wall when translation is advanced all the time, cause steel billet wiping furnace wall in stove, the production development fault, so that blowing out stops production.
2. at whole furnace bottom, one circle water sealed tank is arranged, 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, the heating two sections burner power increase successively, soaking zone burner power is lower slightly.This burner decoration form, following shortcoming is arranged: rate of heating is slower, and productivity is lower, and oxidization burning loss is more.
Summary of the invention
The purpose of this utility model is to solve the above-mentioned three aspects: problem that existing stepped start-stop system heater for rolling steel exists, and 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: improve for existing stepped start-stop system heater for rolling steel, 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 installed all, be provided with the fixedly end and movable blade in the bottom of body of heater, 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 consist of 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, the 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 equipped with aligning gear on a sidewall of the blank easy offset direction of body of heater, the push rod of aligning gear is arranged over against blank, b. described water sealed tank is fixedly to be equipped with on the 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 utility model is to be positioned on the front end side wall of one section of body of heater heating to arrange.
Three sections burner power that are arranged on described in the utility model 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 utlity model has following advantage:
1. the utility model has been set up aligning gear, has blank bias correcting function.Suppose that the blank position is 120 in stove, suppose that the walk deviator of blank when every row is further is 2mm, cover that total deviator of walking is 240mm after all material levels, cause blank wiping furnace wall and the stopping production blowing out.The utility model is mainly by aligning gear, after can realizing in stove occuring in the blank traveling process skew to a certain degree, the blank position is corrected placed in the middle, thereby prevent that the blank skew from causing the wiping wall.
2. the utility model improves the installation form of furnace bottom water sealed tank, water sealed tank is fixed on the furnace bottom column, change movable for fixed, during stove work, the dump bottom motion, movable blade is followed the translation up-and-down movement, water sealed tank maintains static, thereby the water of having avoided original water sealed tank rocks because of translation and overflows, and has reduced again the load of furnace bottom driving device simultaneously, has reduced consumption and the rate of breakdown of electric energy.
3. for design improvement on ratio of specific heat, this design is conducive to more to realize that cold base enters the heat of forcing after stove to the utility model, shortens heat-up time thereby reach, and boosts productivity, and reduces energy consumption and oxidization burning loss at full stove.
