Abstract
The invention relates to an automatic ladle weighing system and a method. The system comprises a ladle rotating table, wherein the ladle rotating table comprises two rotating arms, each rotating arm is provided with two weighing box bodies, each weighing box body is internally provided with two weighing sensors used for acquiring the weight information of the weighing boxes, the weighing sensors are connected with a central control module through an analog quantity acquisition conversion module, and the central control module is connected with two display screens used for respectively displaying the weight information acquired by each sensor on the two rotating arms. According to the system, the force bearing information of each sensor is detected independently, so each sensor on the single arm is guaranteed to realize force bearing consistency.
Description
Technical field
The present invention relates to ladle turret design field, particularly a kind of ladle is weighed automated system and method.
Background technology
Ladle turret is to apply most common delivery and support ladle to carry out the equipment poured into a mould in modern continuous casting, is generally disposed at molten steel and receives between casting bay colonnade.
Ladle turret is one of key equipment of conticaster, plays the important function connecting upper and lower two procedures.The revolution situation of ladle turret consists essentially of both sides has ladle, both sides to have three kinds of situations of ladle without ladle, one side, and single ladle weight is more than 140 tons.In the case of three kinds, ladle turret stress is very different, but the most under what circumstances, will ensure that the rotation of ladle turret is steady, accurate positioning, to reduce the impact to mechanical part during start-stop as far as possible, for reducing pouring basket liquid level fluctuation and temperature drop, rotational time to be shortened.
Tradition ladle weighing system single armed Weighing module is when adjusting sensor horizontal position, it is impossible to realize effectively and rapidly mixing up the horizontal level of left and right LOAD CELLS, and to ensure between single armed module distribution of force is uniform.Tradition casing of weighing when adjusting single armed force acting on transducer, can only correct each force acting on transducer point ground horizontal level by horizon rule, it is ensured that balance.And in practical operation, single armed due to be divided into left and right two supporting cannot normally mix up at all left and right two supporting between level height.
Summary of the invention
In view of this, the purpose of the present invention is to propose to a kind of ladle and weigh automated system and method, by individually detect each sensor by force information, it is ensured that each force acting on transducer of single armed is consistent.
Assembly of the invention uses below scheme to realize: a kind of ladle is weighed automated system, including ladle turret, described ladle turret includes two pivoted arms, two casings of weighing it are provided with on each pivoted arm, each box house of weighing is provided with two LOAD CELLSs, in order to gather the weight information of casing of weighing；Described LOAD CELLS is connected to central control module by analog acquisition modular converter, and described central control module connects has two display screens, respectively in order to show the weight information of each sensor acquisition on two pivoted arms.
Further, described central control module includes PLC.
Further, described central control module connects Schneider GXO5502 touch screen.
Further, said two pivoted arm is arranged with hydraulic lift, and described hydraulic lift is electrical connected with described central control module.
The method of the present invention uses below scheme to realize: the method for automated system of weighing based on ladle mentioned above, specifically includes following steps:
Step S1: ladle turret is started working, ladle is put into described in weigh casing；
Step S2: described LOAD CELLS Real-time Collection weight information, and weight information is passed to described analog acquisition modular converter by 0-200mv signal；
Step S3: the weight information changed is passed to central control module by described analog acquisition modular converter, data are carried out adding up and obtain the gross weight that two pivoted arms each bear by described central control module；
Step S4: in gross weight information that two pivoted arms are each born by described central control module and two-arm, the weight information of each sensor acquisition is delivered separately to the display screen corresponding to two pivoted arms by RS485 MOUBUS RTU bus；
Step S5: according to the level height between two pivoted arms of the data point reuse on display screen.
Further, described central control module connects Schneider GXO5502 touch screen.
Further, described step S5 is particularly as follows: the supporting-point height of two pivoted arms of regulation is until the gross weight each born of two pivoted arms is consistent.
Further, said two pivoted arm is arranged with hydraulic lift, and described hydraulic lift is electrical connected with described central control module.
Further, described step S5 is particularly as follows: hydraulic lifts corresponding to two pivoted arms of regulation are until the gross weight each born of two pivoted arms is consistent.
Compared with prior art, the present invention has a following beneficial effect: the present invention utilizes analog acquisition modular converter that by original " one-to-many " LOAD CELLS upgraded to " one to one " and takes pattern.Cancel and use original meter specially, increase high-end display terminal " Schneider GXO5502 touch screen " by RS485 agreement and show.Owing to each sensor has stress monitoring display individually, as long as can ensure that each force acting on transducer of single armed is consistent by adjusting supporting-point height.Simultaneously the present invention by monitor each sensor by force information, when a failure occurs it, it is possible to reduce maintenance time, and reduce product man after-sale service expense.
