1.3 Mould trolley
The crystallizer car for crystal fixed device, it can lateral movement for loading and unloading mould, guide and cast the head and the lifting of the ingot, mould trolley has positioning and locking device, to so that the car can firmly in the lead cast position by car to replace the relief panel, can adapt to different specifications and flow number of crystallizer. Configuration of frequency conversion vibration motor drive device, its power is 2.2kW, the vibration frequency is 0 ~ 160 times /min, the amplitude is 0 ~ 12mm.
The inner wall of the crystallizer materials for copper (also by party a production resources, zirconium and copper), graphite impregnated set is in favor of improving the surface quality. In addition to conventional methods, the principle of continuous casting of steel can be drawn from the use of a narrow slit type high water speed cooling mold to facilitate the effective avoidance of partial boiling of cooling water.
Cooling water pressure: 0.05 ~ 0.15MPa cooling water comsumption: 80 ~ 100m³/h
1.5 Protective atmosphere cover
The protective atmosphere cover can be through the gas protective agent (industrial gas) to protect the liquid level inside the crystallizer, reduce the defects of oxide slag.
1.6 Water cooling system
The water cooling system is mainly used for the cooling of production line equipment, namely for the sensor shell, a coil, a water jacket, a water cooled cable, transformer, phase equilibrium reactor; it consists of a water dispenser, backwater collector and associated piping, valves and other, including return type can by pressure and two kinds of pressure for the Party of choice; has functions such as water pressure, backwater temperature display, control and alarm, interlock.
1.6.1 Inlet pressure: 0.3 ~ 0.4MPa,
1.6.2 Inlet temperature: 5 ~ 45 degrees,
1.6.3 Water consumption: 18 ~ 20t/h
1.6.4 Outlet temperature: less than 55℃,
1.6.5 Allowing the temperature to rise: less than 20℃ (at the maximum inlet temperature),
1.6.6 Total hardness (CAO): less than 10mg equivalent /L,
1.6.7 Water resistance: greater than 2000 / cm.
1.7 Hydraulic system
The hydraulic system for melting furnace lifting tilting, a furnace cover open and closed and insulation pouring furnace before and after walking, lifting and dumping, opening and closing lid, adopts hydraulic station centralized supply pressure liquid, electro-hydraulic valve control.
Basic parameters: oil tank (appearance): 1300 * 900 * 700mm (stainless steel)
