4,?main composition of the production line equipment
?4.1 Two conjoined frequency cored induction furnace
? ? The electric furnace is mainly composed of a furnace cover, a furnace shell, an induction body, a support, an electric control system, a temperature measuring system and a cooling system of the equipment.
? ? The furnace shell and the bottom bracket of the upper furnace body are welded with the Q235 steel plate and the steel plate, and the lower part of the smelting induction body and the heat insulation induction body are connected with the upper furnace body through a flange. Melting groove is made of red copper casting; core with Japan Z10 silicon steel laminations loaded into; coil with double glass ribbon wrapped rectangular copper winding and, good insulation, strong cooling effect; water cooling jacket is made of stainless steel plate 1Cr18ni9Ti thickness 3mm, it has high strength, vibration magnetic effect good. The furnace chamber is divided into three cavities, the melting chamber, the intermediate excessive cavity, the thermal insulation cavity. Melting chamber of material function; excessive cavity is mainly static copper water, reducing smelting furnace material temperature fluctuation effect of furnace temperature on the thermal insulation, heat preservation cavity is mainly to give traction bar provide stable molten copper and stable temperature.
? ? ?Two conjoined frequency cored induction furnace?control system, melting and insulation department are used step self coupling voltage regulating transformer to adjust the pressure, adjustable pressure profile of 380V, 340v, 300V, 270V, 240V, 210v, 180V, 150V, 120V, 90V voltage (line). Melting, thermal insulation furnace temperature control are equipped with manual and automatic conversion switch, when the switch is in the manual, artificial regulation of voltage knob for regulating the output voltage of a transformer, so as to control the power output of the electric furnace; when the switch is arranged in the automatic control system by artificial intelligent temperature controller to adjust the output voltage of the transformer pressure. An automatic temperature control system is arranged in the heat insulating part of the smelting part. The thermocouple is a horizontal inserting type, and the heat insulating part is an inserting type.
4.2 copper alloy lead mould
? ? The mold is made of one cooling and two cooling. The cooling jacket is made of heat resistant steel, and the other parts are made of cold rolled steel sheet. With water grooves in the mold on the cooling water in the mold directional flow, so as to ensure the uniformity of cooling.
? ? Cooling water distribution system is specially designed for the cooling of the mould. The system is provided with a water inlet flow meter and a water outlet thermometer, which is convenient for the user to monitor and adjust the water system. I
