The specific fire extinguishing area and mode of operation are as follows
● Mill body (including flue) - the automatic, manual and mechanical electrical manual operation; due to the host and the oil and oil tank with the combination of distribution system, which belongs to the system to ensure that each call, if you choose the valve once opened up under the condition of "the system can start fire extinguishing equipment.
● Underground oil storage - automatic, electrical, manual and mechanical manual operation
● Tank - full automatic, electrical, manual and mechanical manual operation;
● Flue - Electrical, manual and mechanical manual operation;
● Work roll gap - Electrical, manual and mechanical manual operatio
2) the rolling mill main body (including flue), underground oil depot and oil storage tank are protected by combined fire extinguishing mode, and the roll gap is protected by independent fire extinguishing mode, and one or two fire extinguishing functions are set up.
3) the working roll gap is protected by independent type, designed for the two fire extinguishing function. IG01 argon fire extinguishing system is adopted.
4) the rolling mill body and work roll gap, the oil storage tank adopts partial fire extinguishing mode, and the rest adopts full flooded fire extinguishing mode. When the mill body, the work roll gap and the oil tank start fire extinguishing device, there is no delay, while the remaining areas are set 30 seconds delay function.
The depot, main tunnel protected areas inside and outside are set up a sound and light alarm device, to ensure the safety of personnel evacuation in fire extinguishing agent should be issued before the release, fire alarm, fire alarm and fire extinguishing agent release delay time should be set in accordance with the actual situation of the test, not deliberately set 30S; for the delay of the bar machine body, flue, filter, do not meet the conditions of stick seam, immediately injection; filter alarm, underground oil and alarm; alarm host, underground oil and waste at the same time in order to ensure the reliability of fire alarm; the fire system in the prior to the release of fire extinguishing agent or at the same time, should guarantee the necessary linkage operation. The fire extinguishing system in a fire control system sends out the instruction, by linkage instruction, power off, shut down or stop all affect the suppression effect in the actual operation of equipment; The detection system is the use of "and" circuit, all areas should be in the automatic state, and should not make any area in the state of manual control, because the automatic state of manual control is preferred, because in this control mode in malfunction probability is very low; the main entrance of operating platform, operation Taiwan, Taiwan export operations are provided on the host (main and standby area) operation button; the main operating units arranged near the three button, as the roll gap, host (main and standby area) the stop button, the button of the remaining districts divided into body and main operation mode of two kinds of control room, but the main operation room to button and roll gap (main spare area) button placed separately; the host, underground oil tanks, trenches, etc. the main plate filter fire extinguishing area are set manually stop button facilities.
