The invention discloses a compact hot metal conveying system. The system comprises a blast furnace area (100), a steelmaking workshop (200) and a transition bay (300), wherein a blast furnace (1) is arranged in the blast furnace area (100), an iron outlet of the blast furnace (1) is provided with a hot metal conveying line (5), the steelmaking workshop (200) is provided with a converter (7) and a feeding bay (11), the hot metal conveying line (5) in the blast furnace area (100) extends into the feeding bay (11), and the transition bay (300) is located between the blast furnace area (100) and the steelmaking workshop (200) and is used for hot metal buffering during accidents in the steelmaking workshop (200). The blast furnace area (100), the steelmaking workshop (200) and the transition bay (300) are arranged in parallel and connected through the hot metal conveying line (5), and the hot metal conveying line (5) is arranged vertical to the blast furnace area (100), the steelmaking workshop (200) and the transition bay (300). The compact hot metal conveying system is smooth in process, compact in general drawing, low in investment and operation cost, and suitable for newly-built integrated iron and steel enterprises.

The invention discloses a reinforcement cage hoisting mechanism and a reinforcement cage conveying line. The reinforcement cage hoisting mechanism comprises a cross beam capable of moving up and down, and a reinforcement cage retaining device connected to the cross beam. The lower part of the reinforcement cage retaining device is provided with an open slot capable of at least partially accommodating the reinforcement cage. A first bolt and a second bolt which are inserted into a reinforcement cage and can clamp the reinforcement cage are respectively arranged on two longitudinal sides of the lower part of the open slot. The first bolt and the second bolt can reciprocate in the longitudinal direction and are oppositely arranged or arranged in a staggered mode in the transverse direction. By the adoption of the structure, due to the gravity of the reinforcement cage retaining device and an arc-shaped structure of surfaces of upper reinforcing steel bars on the reinforcement cage, the reinforcement cage is forced to rotate or the reinforcement cage retaining device slides along the surfaces of the upper reinforcing steel bars on the reinforcement cage, then the upper surface of the reinforcement cage is completely contained in the open slot, the reinforcement cage retaining device can conveniently position the reinforcement cage and allow the bolts to be inserted during hoisting, and the cage grabbing reliability is improved; and meanwhile, the bolts are longitudinally and horizontally inserted, so that the reliability of cage grabbing and unhooking is ensured.

The invention provides a novel high-performance hydrofluoric acid-resistance artificial functional composite plate and a preparation method thereof. The plate is mainly made of barite aggregate, resin and a serial of modified agents. According to the preparation method, the finished plate can be formed after a serial of processes of barite packing graduation, special resin and the serial of modified agents adding, mixing and stirring, organic combination reaction, plate blank forming, high-temperature and high-pressure reaction, high-frequency vibration, cure reaction (80-120 DEG C), thickness determining, polishing, bridge cutting, detection and the like. The composite plate has special anti-corrosion performance, excellent mechanical performance and durability, and is superior in product conveying, installation, maintenance and the like.

Methods for uniformly distributing a flowing medium to a surface such as that of a rotary liquid permeable roll are disclosed where the flowing medium is distributed by a number of distribution units, the method including distributing the flowing medium to each of the distribution units and separately controlling the flow of the flowing medium to each of the distribution units whereby a uniform flow and an equal amount of the flowing medium is obtained in each of the distribution units. Distribution devices for uniformly distributing a flowing medium to such a surface are also disclosed.

The invention discloses a collocation method for fusing an intelligent plane warehouse and an overhead warehouse in aluminum plate strip production equipment. The intelligent plane warehouse is arranged between a hot rolling workshop and a cold rolling workshop; the overhead warehouse is arranged among an annealing furnace, each finishing unit and a tray conveying mechanism; a track for running of a plurality of coil cars is mutually vertical to the tray conveying mechanism; and a track for a plurality of discharge cars in the overhead warehouse extends beside the annealing furnace or the each finishing unit. Hot-rolled coils on a hot mill discharge mechanism are hoisted to the corresponding positions for storage or cooling through an intelligent crane in the intelligent plane warehouse, and cold-rolled coils are stored at the corresponding positions through a stacker or cooled in the overhead warehouse. The aluminum plate strip production equipment collocated with the intelligent plane warehouse and the overhead warehouse is totally adjoined, needs no transport equipment such as the crane, a forklift or an automatic vehicle and the like, has the effect on shortest transport distance, realizes good circulation of low-carbon production of aluminum plate strips, and has the characteristics of lowest product storage quantity and shortest production period.

The invention relates to a method for processing dust when breaking rock, to a dust separator, and further to a rock-drilling rig. Rock material and air sucked from a borehole or some other operating location is separated from each other in the dust separator. The separated rock material falls into a discharge part of the dust separator, from which it can be dosed in batches into a discharging device. The discharging device comprises a closed compression space in which the rock material batch is compressed into a more compact state. This forms a solid matter cake that is removed from the dust separator.
