1. We use Oxford Instruments spectrometer to check the chemical
composition for every heat, components conform to the requirements
of the
process before the iron.
2. Each casting ladle pouring tap on a block, tapping experiment
was carried out, judge the inoculation
3.Ball reaction after strict control of pouring time, must complete
pouring in 9 minutes, use time alarm system, overtime alarm, to
prevent a
spheroidizing recession phenomenon
4. Strictly control the size of the groove, ensure compliance with
standards
5. Grooved fittings surface coating epoxy resin, improve the
ability to resist corrosion
6. Is advantageous to the construction safety, the system stability
is good, easy maintenance
7. Each furnace batch has the traceability
8. The pipe fittings have outlets ranging from 1” through 24”
