During the operation of color coated board curing furnace, the following safety problems should be paid attention to
(1) The washing operation must be carried out before each start-up of the curing furnace for the color coated sheet.
(2) The flammable gas concentration measuring device of the color coated board curing furnace must be regularly repaired according to the requirements of the spot check table in order to prevent the device from malfunction and causing explosion danger.
(3) According to the requirement of periodic checklist, the gas tightness of the gas pipelines of each burner is checked regularly by hand-held gas detector (for the solidifying furnace of burning gas).
(4) If there is a sudden power failure in the production process, the burners in each heating area must automatically cut off the fuel supply, so that the burner can be extinguished.
(5) After the accident stops, if you want to start the furnace again, you must wash the furnace.
(6) If he ignition of the burner is unsuccessful, it must be purged for more than 2 minutes before ignition again.
(7) Fireworks are strictly prohibited in the furnace area and good ventilation is maintained.
(8) Operators should inspect the furnace area on a round trip. Once gas leakage and solvent-containing gas escape out of the furnace are found, the causes should be identified as soon as possible and timely treatment should be carried out. If the problem can not be solved effectively, temporary shutdown should be considered. At the same time, pay close attention to the lubricating oil level and cooling water temperature of bearing seat of high temperature fan. When oil level is low, timely refueling and cooling water temperature is increased. The reasons should be found out and solved quickly, and shutdown and maintenance should be considered when the problem can not be solved in time.
