Description
Technical field
The invention belongs to steel-making corollary equipment technical field, particularly relate to a kind of ladle bottom blowing air brick detaching device and method of work thereof.
Background technology
Ladle bottom blowing gas is steel plant for stirring molten steel, evenly molten steel composition and temperature and removing a kind of conventional means of field trash in molten steel, pernicious gas.Bottom-blown air brick is positioned at ladle bottom, is covered by molten steel, and condition of work is very severe.Because the erosion of molten steel and molten steel solidify on air brick, air brick pore is easily caused to block.Therefore, often need to change air brick.
In the past for a long time, steel plant changed air brick of steel ladle two kinds of exemplary process.A kind of mode is with crane for hoisting steel pipe, extend in ladle, then promotes steel pipe by the workman at scene and clashes into air brick, by knocking-on for air brick ladle bottom.Not only there is operational hazards in this substitute mode, the working environment of workman is very severe, and takies the working time of crane.Another kind of mode bale breaker is holed air brick from ladle bottom, is then extracted.This mode easily damages the refractory material of ladle bottom, thus reduces the service life of ladle, and in air brick demolishing process, refractory material splashes, and easily causes on-the-spot confusion even to accidentally injure workman around.
Summary of the invention
The object of the present invention is to provide a kind of ladle bottom blowing air brick detaching device and method of work thereof, under the condition not taking the crane working time, easily can remove ladle bottom blowing air brick.Can not only accurately remove ladle bottom blowing air brick, and the condition of work of workman can be improved, shorten the take-down time, increase work efficiency.Meanwhile, can ensure not cause any destruction to ladle bottom refractory material.
The present invention mainly comprises bore bit 1, drill steel 2, bit shank 3, holder pricker device 4, beater mechanism 5, falsework 6, falsework hydraulic cylinder 7, connecting pin 8, balladeur train 9, balladeur train hydraulic cylinder 10, workbench 11, device adjustment mechanism of center 12, longitudinal adjusting mechanism 13, control cabinet 14, lateral adjustment 15.This device end is heat-resisting bore bit 1, and shaft is drill steel 2, and drill steel 2 is connected with beater mechanism 5 through holder pricker device 4, and beater mechanism 5 is positioned on falsework 6, and falsework 6 is welded on the shell of falsework hydraulic cylinder 7.Balladeur train 9 is fixed on workbench 11, and is connected with falsework 6 by the connecting pin 8 of balladeur train hydraulic cylinder 10 afterbody.Device adjustment mechanism of center 12, longitudinal adjusting mechanism 13, lateral adjustment 15 are arranged in the left side of workbench 11, right side and below, and control cabinet 14 is placed on the end of workbench 11.
Drill steel length is 3000mm ~ 3500mm; Falsework hydraulic cylinder works stroke is 4000mm; Balladeur train hydraulic cylinder works stroke 3500mm.
Ladle 16 internal temperature is higher, remove air brick 17, requires that the end of air brick detaching device need have higher hardness and heat resistance.For solving the problem, the end of described ladle bottom blowing air brick detaching device is heat-resisting bore bit 1, and shaft is drill steel 2, and bore bit 1 is detachable.
Ladle 16 has certain degree of depth, the bore bit 1 of air brick detaching device be made to arrive working position, not only require that drill steel 2 itself has certain length.Drill steel 2 length is long affects its rigidity, therefore requires that bore bit 1 has certain impulse stroke.In order to solve the problem, described ladle bottom blowing air brick detaching device adopts falsework hydraulic cylinder 7 and balladeur train hydraulic cylinder 10 to combine the mode of propelling.Balladeur train hydraulic cylinder 10 can drive falsework 6 to push ahead, and falsework hydraulic cylinder 7 can drive drill steel 2 and beater mechanism 5 forward impelling simultaneously.Therefore, the impulse stroke of bore bit 1 is the summation of balladeur train hydraulic cylinder 10 impulse stroke and falsework hydraulic cylinder 7 impulse stroke.
Refractory material bottom ladle 16 is easily destroyed under the shock of external force, thus affects ladle 16 service life.Therefore, require that air brick detaching device can accurately remove air brick 17.In order to solve the problem, described ladle bottom blowing air brick detaching device have employed holder pricker device 4, longitudinal adjusting mechanism 13, lateral adjustment 15, device adjustment mechanism of center 12 to realize the accurate location of bore bit 1.Described holder pricker device 4, for fixing drill steel 2, prevents it from departing from direction of propulsion; Described longitudinal adjusting mechanism 13 is screw-nut body, can finely tune bore bit 1, make it up and down; Described lateral adjustment 15 is screw-nut body, can finely tune bore bit 1, movable about making it; Described device adjustment mechanism of center 12 can regulate the center of ladle bottom blowing air brick detaching device to make it align with air brick 17 center.
Under high temperature, air brick 17 meeting sinters with the refractory material bottom ladle 16, remove air brick 17, bore bit 1 need be made to have certain impact.In order to solve the problem, described ladle bottom blowing air brick detaching device have employed beater mechanism 5 to realize the impact function of bore bit 1.Described beater mechanism 5 adopts air cylinder driven, and after bore bit 1 arrives working position, beater mechanism drives drill steel 2, makes bore bit by bottom knocking-on for air brick 17 ladle 16.
Job step is as follows:
(1) adjusting device adjustment mechanism of center 12 makes ladle bottom blowing air brick detaching device roughly align with air brick 17 center;
(2) balladeur train hydraulic cylinder 10 drives balladeur train 9 to push ahead until reach working position;
(3) falsework hydraulic cylinder 7 drives falsework 6 to push ahead, and stops advancing after bore bit 1 arrives working position;
(4) air cylinder driven beater mechanism 5, makes bore bit 1 clash into air brick 17 until by its knocking-on ladle bottom;
(5), after end-of-job, falsework hydraulic cylinder 7 and balladeur train hydraulic cylinder 10 return original position respectively in order.
The present invention has the following advantages:
This device mainly adopts hydraulic-driven, does not need crane less important work, reduces crane workload; Adopt multiple adjustment mechanisms, assurance device accurately can remove air brick; Device stability is good, and efficiency is high, easy to maintenance; Staff only needs operation site control cabinet 14 can realize air brick dismounting work, ensure that the safety of staff.
