China Centralized Lead Feeding System

Centralized Lead Feeding System

Energy Consumption Comparison

The medium frequency system passed through the actual electricity consumption test of the on-site electric meter and the actual electricity consumption test of the heating tube in 60 days of actual operation, and the comprehensive energy consumption can be reduced by 20%-40%.

It is estimated that a pot of 10 machines can save about RMB 170,000 electricity a year.It saves about RMB20,000 maintenance and replacement heating pipes a year.The actual test uses intermediate frequency heating to produce plates of small size battery, which power consumption of about 100 degrees per ton of alloy.The heating system of the lead pot is changed from electric heating tube heating to medium frequency heating.The adjustable range of heating temperature is wider (up to 550°C);Temperature control is more precise: this control changes the switch control to analog control(within ±10 %)Normally it doesn't need maintenance and replacement : this heating is coil heating. It doesn't need maintenance except coil aging.The heating system of lead feeding pipe is changed from electric heating tube to medium frequency heatingThe adjustable range of heating temperature is wider (up to 550°C);Temperature control is more precise: this control changes the switch control to analog control (within ±10 °C)The heating temperature distribution is more uniform: the medium frequency heating coil of the lead pipe is distributed in a spiral manner, and the temperature can be evenly transmitted to the lead pipe.Normally it doesn't need maintenance and replacement : this heating is coil heating. It doesn't need maintenance except coil aging.Medium Frequency Electrical Cabinet Box

This intermediate frequency electrical cabinet is specially designed for the working conditions and operating environment of the grid casting machine workshop. It is high temperature resistance, easy operation and convenient maintenance.

6.9.Several movements are installed in parallel on the same heating tube without interfering with each other

Good power saving effect: Compared with the currently used electric heating coils, the power saving can reach more than 20%Convenient installation: can be connected to induction coils of barrel type and flat plate type, etc.Low operating cost, less maintenance, product warranty for 1 year, lifetime maintenance.Lead melting furnace (2 sets of 60KW high frequency heating movement 120kw)lead melting furnace: 1pc 7-ton lead melting furnace. High-frequency movement heating method: power 60kw (2 pcs), Lead liquid temperature: 430520°C adjustable, working fluctuation range ±10°C, maximum working temperature 550 C.High-frequency heating method. It needs 4-4.5 hours for the cold lead in the furnace to rise from room temperature to working temperature.

7.1.4. When the temperature rises to the set temperature, it belongs to the heat preservation period, the power drops to 90kw.
7.2 Lead delivery system (12KW high-frequency heating core 2 sets of 24kw)

The lead conveying supervisor is a 083x10 seamless steel pipe (the length varies according to the number of main engines).The automatic temperature control function of the lead pipe can independently control the temperature of the lead pipe.Using high frequency heating method: total power is about 12x2=24KwWhen the temperature rises to the set temperature, it belongs to the holding period, and the power drops to 12kwThe branch outlet of the lead pipe is controlled by a long-flow lead supply valve, and is equipped with a pneumatic shut-off safety main valve, which has the function of heating and heat preservation.Lead pipe insulation material is No. 2 aluminum silicate fiber board, the thickness of the insulation layer is more than 30mm, the outer steel plate material is Q235, the thickness is 1mm.
