Information

1 When the system is in normal operation, the amount of granulated water, purge air, sweep water, the maximum water temperature of the granulator, and the slag flow rate should reach the design specifications.

2 When the system is running, the equipment inspection should meet the following requirements: no abnormality in the special inspection of the equipment, no blockage of the granulation head, no slag block on the receiving trough grid, reasonable high and low ditch and slag gate status, no slag accumulation in the hot water tank, no slag in the pit Water and slag, no leakage of pipeline valves, smooth belt transportation, no deviation, and normal water level in the accident.

3 The slag flushing ditch used in tapping should also have the conditions for diversion of dry slag or other measures to treat slag, and the time for switching the gate and diversion should not exceed 3 minutes.

4 During normal production, the operation of system equipment should be automatically controlled.

5 The system should be started 20 minutes before the iron is tapped, and the operating room can start the system after receiving the "ready" signal. If a start fails, it should not be started continuously immediately.

6 When there are phenomena that endanger the safety of people and equipment during the operation of the system, the operation of the system should be stopped immediately, and the hot slag should be poured into the dry slag pit or slag tank.

7 When iron is tapped, there should be no people near the slag ditch and granulator.

8 The amount of granulated water in the system should be closely watched. If it is found that the amount of granulated water is greatly reduced, the drum is malfunctioning, the belt is carrying water seriously, or the operation room signal has a "big alarm", it should be diverted to the dry slag pit or slag tank immediately to prevent liquid slag from entering the granulation system.

9 After blocking the iron (slag) port for 20 minutes, the system can stop running.

10 After the system is shut down, the power supply of the granulation pump should be stopped first, and then the granulation head, slag ditch, receiving tank, and granulation water pump should be checked and cleaned. To check or replace or clean the nozzle, stop the hydraulic system (close the hydraulic valve). To check the belt, stop the belt conveyor power supply first.

11 System maintenance personnel should not short-circuit the various protection devices of the system, and find equipment abnormalities or accidents, they should quickly judge and deal with them to prevent the accident from expanding; record abnormal phenomena and accidents and report to relevant leaders.

12 The various interlocking and protection devices of the system should not be adjusted at will without the approval of the competent department; if adjustment is really necessary, it should be agreed by the competent department and reported to the professional factory manager for approval; the adjustment should be recorded and archived .

13 When any control handle of the system is in the "auto" position, it should not be overhauled. If the drum movement is required during system maintenance, a dedicated person should be assigned to operate it. 14 When using the wheel flushing slag process, a safety net should be installed near the granulation wheel.
