Scope of operation: primary coating curing furnace, fine coating curing furnace, waste gas incinerator.
Description: the color coated coil steel strip comes out of the roller coating machine and enters the curing furnace through a section
of leveling area. The wet coating of the steel strip is applied in the hot blast furnace.
The color coating roll will form a certain thickness of dry film after drying. The management standard of washing yard: before shift: remove the floating dirt
in the curing furnace, start the circulating fan and exhaust fan for air, clean the combustible gas concentration alarm device, and approve the set value of the lower limit of explosion concentration. According to the effective heating curve of the primary
curing system and the heating alarm of the fine curing system, confirm the temperature. Wash the incinerator and raise the temperature to the set value. After shift: after the heater stops working, the circulating fan and exhaust fan still work for a
period of time to cool the furnace and remove the waste gas in the furnace and clean the surrounding area.
Curing furnace: the temperature control curve in the furnace is directly related to the process conditions such
as the thickness of steel strip, the type of coating, the thickness of color coating coil and the speed of the unit. Although the preset value can be formulated according to experience, the accurate value should be corrected according to the test of dry
film performance, After the coating is cured and cooled to room temperature, the on-line MEK and pencil hardness test should be carried out regularly, and the furnace temperature curve should be adjusted at any time.
Incinerator: during the production
process, check the burning situation at any time, that is, judge the burning effect by furnace temperature and pressure, and use the valve in front of the chimney to adjust. In addition, the pressure balance point between the curing furnace and the incinerator
should be well controlled through the opening and closing of the air pipe ram for waste gas transmission, and the operation principle and safety matters of the furnace area should be well controlled.
