Accompanying drawing explanation
The device sketch of the fast pace tapping set that Fig. 1 provides for the embodiment of the present invention.
The specific embodiment
Referring to accompanying drawing 1, a kind of fast pace tapping method provided by the invention comprises:
Determine the tapping order of three walking beam furnaces according to walking beam furnace and the distance of thick descaling mill 5; When the steel billet that walking beam furnace is sent passes through the position of corresponding with it thermometal survey meter, thermometal survey meter can excite wants steel signal; Determine walking beam furnace tapping according to wanting steel signal.
Wherein, determine that according to walking beam furnace and the distance of thick descaling mill 5 the tapping order of three walking beam furnaces comprises:
Select 4 walking beam furnaces, the thick descaling mill 5 of distance is from the close-by examples to those far off set to respectively No. 1 heating furnace, No. 2 heating furnaces, No. 3 heating furnaces, No. 4 heating furnaces; When production work, use wherein 3, remaining one for subsequent use.
3 walking beam furnaces are numbered with the distance of thick descaling mill 5 according to 3 walking beam furnaces that use; Determine the tapping order of 3 walking beam furnaces according to the numbering of walking beam furnace.
Wherein, 3 walking beam furnaces are numbered with the distance of thick descaling mill 5 according to 3 walking beam furnaces that use; The tapping order of determining 3 walking beam furnaces according to the numbering of walking beam furnace comprises:
The walking beam furnace nearest with thick descaling mill 5 is numbered I heating furnace.
The walking beam furnace near with thick descaling mill 5 distances second is numbered II heating furnace.
Be numbered III heating furnace with thick descaling mill 5 distances walking beam furnace farthest.
The tapping order of described walking beam furnace is I II III I II III sequential loop tapping by number, and circulation tapping can guarantee that the steel billet quantity in each walking beam furnace is even in this order.
Wherein, thermometal survey meter is arranged on the position outside walking beam furnace:
3 thermometal survey meters are respectively: the first thermometal survey meter 6, the second thermometal survey meter 7 and the 3rd thermometal survey meter 8.
The first thermometal survey meter 6 is arranged between No. 1 heating furnace 1 and thick descaling mill 5, and apart from position more than No. 1 heating furnace 1 furnace wall 0.5m, the first thermometal survey meter 6 is as far as possible near No. 1 heating furnace 1.
The second thermometal survey meter 7 is arranged between 1 and No. 2 adjacent furnace walls of heating furnace 2 of No. 1 heating furnace and apart from positions more than two furnace wall 0.5m, and the second thermometal survey meter 7 is as far as possible near No. 2 heating furnaces 2.
The 3rd thermometal survey meter 8 is arranged between 2 and No. 3 adjacent furnace walls of heating furnace 3 of No. 2 heating furnaces and apart from positions more than two furnace wall 0.5m, and the 3rd thermometal survey meter 8 is as far as possible near No. 3 heating furnaces.
3 thermometal survey meters are in principle respectively as far as possible near 2, No. 3 heating furnaces 3 of 1, No. 2 heating furnaces of No. 1 heating furnace, can be excited the soonest to accelerate to tap rhythm, but can not be excessively near apart from furnace wall, in order to avoid steel billet excites it in tapping action by mistake and cause tapping chaotic.
Wherein, when the steel billet that walking beam furnace is sent passes through the position of corresponding with it thermometal survey meter, thermometal survey meter can excite wants steel signal to comprise:
The steel billet that I heating furnace is sent is placed on transfer roller 9; The traffic direction of transfer roller 9 is directions that steel billet is transported to thick descaling mill 5; When I heating furnace is No. 1 heating furnace 1, when steel billet is sent to head and arrives the position of the first thermometal survey meter 6, triggers the first thermometal survey meter 6 and excite first to want steel signal SIG1.
When I heating furnace is No. 2 heating furnaces 2, when steel billet is sent to head and arrives the position of the second thermometal survey meter 7, triggers the second thermometal survey meter 7 and excite first to want steel signal SIG1.
The steel billet that II heating furnace is sent is placed on transfer roller 9; When II heating furnace is No. 2 heating furnaces 2, when steel billet is sent to head and arrives the position of the second thermometal survey meter 7, triggers the second thermometal survey meter 7 and excite second to want steel signal SIG2.

According to wanting steel signal to determine next walking beam furnace tapping, comprising:
First wants steel signal SIG1 to determine that the walking beam furnace of next tapping is II heating furnace.The steel billet of now being sent by I heating furnace has excited first to want steel signal SIG1, so, I heating furnace starts to prepare tapping next time, and because tapping action need to expend the regular hour, so interlude is long between twice tapping of I heating furnace, therefore in order to accelerate heating furnace tapping rhythm, first wants steel signal SIG1 not want steel to I heating furnace, and the first walking beam furnace of wanting steel signal SIG1 to determine that the next one is tapped has just been got rid of I heating furnace.We start to consider to want steel to II, III heating furnace so, because the distance of the thick descaling mill 5 of III heating furnace distance is than the distance of II heating furnace, the steel billet of so now III stove tapping need to be sent to the position of thick descaling mill 5 the longer time, so just be unfavorable for optimizing tapping rhythm, so first wants steel signal SIG1 should determine that the walking beam furnace of next tapping is II heating furnace.
Second wants steel signal SIG2 to determine that the walking beam furnace of next tapping is III heating furnace.The same situation, second wants steel signal SIG2 not want steel to II heating furnace.If want steel to I heating furnace simultaneously, the steel billet that the steel billet of sending from II heating furnace may be sent with I heating furnace on transfer roller clashes, cause the relative collision of steel billet even to cause producing line catastrophe failure, therefore second want steel signal SIG2 should determine that the walking beam furnace of next tapping is III heating furnace.
The 3rd wants steel signal SIG3 to determine that the walking beam furnace of next tapping is I heating furnace.With reason above, the 3rd wants steel signal SIG3 not want steel to III heating furnace and II heating furnace, the 3rd wants steel signal SIG3 need to determine that the walking beam furnace of next tapping is I heating furnace.
