Abstract

The utility model discloses a relate to the production of walking beam formula heating furnace control field, especially a be used for walking beam formula heating furnace heating control system. Be used for walking beam formula heating furnace heating control system, package rubbing board base rollgang, programmable controller, heating furnace, the slab rollgang sets up the front end at the heating furnace, the switching of programmable logic controller control heating furnace still includes temperature measurement mechanism, the temperature measurement establishment of institution just is connected with programmable controller at the end of slab rollgang. The utility model provides a be used for walking beam formula heating furnace heating control system, but control system accurate control slab is at the heat time of heating furnace.

Description

For walking beam heating furnace heating control system
Technical field
The utility model relates to walking beam heating furnace production control field, especially a kind of for walking beam heating furnace heating control system.
Background technology
In Rolling production process, slab needs to be produced by cold rolling or hot rolling to become steel volume. In hot rolling is produced, it is necessary to slab is heated to 1100 DEG C-1200 DEG C by process furnace. Slab directly carries out hot rolling after producing primarily of continuous casting working procedure, between board briquette 200 DEG C-700 DEG C, but due to the reason such as the production program, output sometimes, it is necessary to using warehouse to store slab, the board briquette that warehouse stores is below 100 DEG C. At present, before slab is delivered to process furnace by slab rollgang, the origin of heat of process furnace is coal gas, process furnace all carries out shove charge heating using 300 DEG C of initial temperatures as slab, causes some heating of plate blank superfluous, and some board briquette is inadequate, the time only increasing heating meets the requirement produced, heating of plate blank surplus causes heat-up time too much, and the waste of coal gas increases cost.
Practical novel content
Technical problem to be solved in the utility model is to provide a kind of for walking beam heating furnace heating control system, and described Controlling System can accurately control the heat-up time of slab at process furnace.
The utility model solve that its technical problem adopts for walking beam heating furnace heating control system, comprise slab rollgang, programmable logic controller, process furnace, described slab rollgang is arranged on the front end of process furnace, the opening and closing of described Controlled by Programmable Controller process furnace, also comprise temperature measuring mechanism, described temperature measuring mechanism is arranged on the end of slab rollgang, and is connected with programmable logic controller.
Further, described temperature measuring mechanism is infrared thermometer, and it measures range is 0 DEG C-1000 DEG C.
Further, described temperature measuring mechanism is two infrared thermometers, is separately positioned on slab rollgang both sides, and one is measured range is 0 DEG C-300 DEG C, and another measures range is 0 DEG C-1000 DEG C.
Further, also comprising cold metal detector, taking slab working direction as benchmark, described cold metal detector is arranged on before temperature measuring mechanism.
The beneficial effects of the utility model are: before process furnace put into by slab, by temperature measuring mechanism, slab is carried out temperature detection, obtain the temperature entering stokehold of slab, then temperature being transferred to programmable logic controller, programmable logic controller, through process, obtains and controls the time that slab heats in process furnace, thus accurately control the heat-up time of slab, use the energy (coal gas) rationally and effectively, reduce the waste of coal gas, reduce production cost.
Accompanying drawing explanation
Fig. 1 is control framework schematic diagram of the present utility model.
Embodiment
Below in conjunction with accompanying drawing, the utility model is described in further detail.
As shown in Figure 1, the utility model is used for walking beam heating furnace heating control system, comprise slab rollgang, programmable logic controller, process furnace, described slab rollgang is arranged on the front end of process furnace, the opening and closing of described Controlled by Programmable Controller process furnace, also comprising temperature measuring mechanism, described temperature measuring mechanism is arranged on the end of slab rollgang, and is connected with programmable logic controller. Before slab is delivered to process furnace by slab rollgang, before process furnace put into by slab, by being arranged on the temperature measuring mechanism of the end of slab rollgang, slab is carried out temperature detection, obtain the temperature entering stokehold of slab, then temperature is transferred to programmable logic controller, programmable logic controller is through process, obtain and control in bar plate heating stove time of heating, thus accurately control the heat-up time of slab, use the energy (coal gas) rationally and effectively, reduce the waste of coal gas, reduce production cost.
Concrete, described temperature measuring mechanism is infrared thermometer, and it measures range is 0 DEG C-1000 DEG C. Infrared thermometer temperature-measuring range is wide, and result is relatively accurate, and production and application is effective, is easy to change.
Concrete, owing to the temperature of slab is when 0 DEG C-300 DEG C, the surface of slab can not be rubescent; The slab of more than 300 DEG C, slab surperficial rubescent, it is possible to from appearance the scope of board briquette being carried out preliminary judgement. Temperature in order to make temperature measuring mechanism record is more accurate, and temperature measuring mechanism of the present utility model can be two infrared thermometers, is separately positioned on slab rollgang both sides, and one is measured range is 0 DEG C-300 DEG C, and another measures range is 0 DEG C-1000 DEG C. Because the range ability of infrared thermometer is more little, the result accuracy rate recorded is more high, more accurately. First by difference in appearance, steel slab surface does not have rubescent, and the infrared thermometer that employing measurement range is 0 DEG C-300 DEG C carries out surveying temperature, otherwise is the infrared thermometer of 0 DEG C-1000 DEG C with measurement range. For the ease of automatic control, taking slab working direction as benchmark, slab puts in place to judge to arrange cold metal detector before temperature measuring mechanism.
