Specification of 45°Elbow:

	We use  Oxford Instruments spectrometer to check the chemical composition for every heat, components conform to the requirements of the process before the iron.
Each casting ladle pouring tap on a block, tapping experiment was carried out, judge the inoculation.
	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.
Strictly control the size of the groove, ensure compliance with standards.
	Grooved fittings surface coating epoxy resin, improve the ability to resist corrosion.
Is advantageous to the construction safety, the system stability is good, easy maintenance.
	Each furnace batch has the traceability.
The pipe fittings have outlets ranging from 1” through 24”.
