The invention discloses a heating control system of an electric heater, comprising a control unit and a heating part, wherein the control unit is used for controlling the heating part; the heating part comprises a first heating unit and a second heating unit. When the control unit receives a third signal from a switch unit, a timing unit is started to begin timing, and one of the first heating unit and the second heating unit is started; when the time counted by the timing unit reaches the preset time, the timing unit sends a switching signal to the control unit, and the timing unit is cleared and the time is counted again; when the control unit receives the switching signal from the timing unit, the control unit makes one, which is opened, of the first heating unit and the second heating unit closed, and makes one, which is closed, of the first heating unit and the second heating unit opened, so that the opening and the closing of the first heating unit and the second heating unit are switched.

The invention relates to a water leakage preventing method in the metallurgical field, in particular to a method for preventing water leakage of the base of a coherent oxygen lance of an electric furnace and a water cooling plate under the base. The mounted water cooling plate of the coherent oxygen lance is divided into an upper water cooling plate and a lower water cooling plate; the upper water cooling plate is made of steel, the original radian at the middle part of the upper water cooling plate is straightened to ensure that the base of the coherent oxygen lance bulges about 30 mm to theinner part of the electric furnace, so as to enlarge the distance between the coherent oxygen lance and a lower furnace liner and the distance between the lower water cooling plate and the lower furnace liner; the lower water cooling plate is made of copper; the mounting position of the base of the coherent oxygen lance is raised by 200 mm upwards on the original basis, and both the upper water cooling plate and the lower water cooling plate are changed. The method can basically solve the problem of water leakage of the base of the coherent oxygen lance and the water cooling plate under the base, greatly reduce erosion and depletion to the lower liner of the furnace by the coherent oxygen lance, obviously prolong the electric furnace life, reduce the labor intensity of workers, improve the production rhythm and reduce the production cost.

The invention relates to the technical field of internal combustion engine accessory manufacturing, in particular to a piston of an energy-saving environment-friendly mounting clearance pairing piston ring. The piston of the energy-saving environment-friendly mounting clearance pairing piston ring comprises a piston body, a first gas ring and a second gas ring, wherein the first gas ring and the second gas ring are installed on the piston body, one end of an opening of a ring body of each gas ring serves as an extending portion, the other end of the opening of the ring body of each gas ring serves as a lap-joint portion, each lap-joint portion corresponds to each extending portion in length, when lap joint is carried out on each lap-joint portion and each extending portion in a vertical mode to enable the ring body of each gas ring to form the whole circle, a gap which cannot expand along with increase of the abrasion loss of each gas ring is formed between the slope of each extending portion and the slope of each lap-joint portion, a fixed matched proportion is arranged between the gap formed between the slopes at the position of the lap joint of the opening of the first gas ring and the gap formed between the slopes at the position of the lap joint of the opening of the second gas ring, and the value of the fixed matched proportion is 0.035mm-0.18mm to 0.02mm-0.12mm.
