The invention discloses an automatic electric arc furnace sealed inclined track feeding device which comprises an inclined feeding hopper and a lifting inclined hopper, wherein the inclined feeding hopper is connected with a waste steel preheating chamber or an electric arc furnace body; the lifting inclined hopper makes reciprocation lifting movement automatically on the inclined track; a baffle sealing door I and a baffle sealing door II are correspondingly arranged at the bottoms of the inclined feeding hopper and the lifting inclined hopper; the baffle sealing door II is a swinging arc-shaped baffle sealing door II. By adopting the technique, automatic feeding of waste steel can be achieved, so that the overall system is relatively energy-saving, safe and convenient to maintain, has great advantages of investment and construction, and is not only applicable to old electric arc furnace transformation, but also applicable to newly constructed electric arc furnace items, and is wide in applicability.

The invention discloses a hollowed fruit tray. A common fruit tray is structurally changed simply to form the hollowed fruit tray, and the trouble of water accumulation caused to users in daily life is effectively reduced; besides, exquisite patterns carved on partitions make the whole fruit tray more attractive and elegant, and the hollowed fruit tray also has certain enjoyment value.

The invention discloses a root stone detection system which comprises a carrier platform, wherein the carrier platform comprises a power system and a navigation control system; the carrier platform is provided with an information acquisition system; the information acquisition system and the navigation control system are in signal connection with a ground control system; the overall specific gravity of the carrier platform is slightly smaller than that of water, so that the most part of the carrier platform is positioned below the water surface, and only the top end of the carrier platform is exposed out of the water surface; the carrier platform also comprises a base frame; an upper shell with an inverted U-shaped cross section is arranged at two sides of the longitudinal direction of the base frame and above the base frame, so that the base frame and the upper shell constitute a cage structure of which the longitudinal direction is strip-shaped, the two ends are thin and the middle is thick; the base frame and the upper shell constitute a closed housing; a plurality of airbags of which the outer surfaces are mutually connected are arranged around the housing and at the bottom of the housing; and an elastic nylon sheath with a smooth surface is arranged at the outer side of each airbag. The scheme has the beneficial effects that the structure is simple, the design is reasonable, the personal risk is avoided, and the most part of the carrier platform is positioned below the water surface, thereby reducing the influences caused by strong wind and heavy rain.

The invention relates to a controlling method of delaying water leakage of a pinch roll, comprising the steps as follows: (1) when an intermediate blank head of rough rolling incoming materials arrives at a flying shear zone, a photoelectric tube in front of the flying shears is triggered and turned on to transmit the detected signal to BA basic automation, and the flying shears carry out the head cutting according to the shape of the detected intermediate blank head; (2) the pinch roll is controlled by low pressure: after the head of the intermediate blank is cut, the intermediate blank goes into a de-scaling box 1#pinch roll at a de-scaling roller-way speed; and based on the days of the pinch roll using the computer and low pressure control pressure setting, a BA computer calculates the head setting pressure according to the formula 1 and then roll gap is pressed until the pressure reaches the set value; (3) the pinch roll is controlled by high pressure: when the tail of the intermediate blank reaches the number 1 photoelectric tube, the pinch roll is controlled by high pressure; and based on the days of the pinch roll using the computer and high pressure control pressure setting, a BA computer calculates the tail setting pressure of the pinch roll according to the formula 2 and then the roller gap is further pressed until the pressure reaches the set value. The invention has the advantages of increased production operation efficiency, reduced fault time, and prolonged using periods of various pinch rolls.

The invention provides a method for preparing and constructing a waterproof coating for a steel structure roof, which includes: performing basic treatment on the roof of a light steel building to remove floating dust and oil stains on the roof surface, and the roof is spliced ​​by a plurality of plates Obtained: performing waterproof treatment on the leaky nodes of the roof; after the waterproof treatment is completed on the leaky nodes of the roof, spray rubber asphalt waterproof paint on the entire roof to form an overall seamless and continuous waterproof coating film.
