Trolley furnace is really large energy consumption, with the electric furnace
as an example, one is the trolley furnace device capacity. An ordinary RJX-30-9
box resistance furnace has a power of 30kW, while an ordinary C162 lathe has a
capacity of only 7kW. Some large stoves can be installed with a capacity of
hundreds of kilowatts, or even nearly a thousand kilowatts. Second, the working
time of electric furnace is long. Generally speaking, the furnace from heating
to heat preservation to continue the time, some open the furnace to continue to
work for a few days, even as long as months to stop the furnace, and the general
cold processing equipment work nature is completely different.
After the lining is knotted well, how to operate correctly and rationally is
the key to prolong the service life of the trolley furnace and guarantee the
life. - Generally speaking, check whether the water flow in the water cooling
system is unobvious, whether the water pressure and temperature of cooling water
are normal, whether there is leakage phenomenon, and whether the hydraulic
system can work normally before operating the trolley furnace. The operation
should be done, careful not to touch randomly, one person operation, one person
monitoring, and strictly prohibit miscellaneous personnel into the machine room,
prevent electric shock. The melting process to use the dry melting, and do light
discharge, frequent feeding, when the melting furnace melt to reach the need
should be poured out in time, to avoid high temperature increase lining loss;
Frequent observation, when found that the outside of the furnace redness
phenomenon, this is the precursor to the furnace leakage, should be promptly
taken to shut down the intermediate frequency power supply, pour out of the
furnace molten material and other measures, to avoid the occurrence of furnace
leakage accident. In use should also pay attention to, when found that the
furnace lining becomes very thin, can not continue to use, should break off the
old lining to do a new lining, to prevent furnace leakage accident.
As a result of the diversity of hot processing materials and processing
technology, as well as the different technical experience and operating habits,
resulting in the furnace structure on the various. Therefore, in the trolley
furnace non - standard equipment. In general machinery factory, trolley furnace
non-standard equipment accounts for about 60%~70%.
In order to adapt to the development of production, the non-standard trolley
furnace often needs to be modified, so it is difficult to establish the standard
repair process. Non-standard trolley furnace with various components is not easy
to achieve standardization, generalization and serialization, repair must be
prepared before each, which increases the difficulty of repair work.
Trolley furnace, whether non-standard equipment or standard equipment, are
on-site repair. The arrangement of time and space, the delivery of materials for
repairing the furnace, the preparation of tools and appliances, the supply of
energy such as water, electricity and compressed air, and the maintenance of
sanitation on the site should be arranged comprehensively according to the
production and site conditions. This puts forward higher request to the
organization of repair work.
