The comprehensive strip steel inspection testing platform is used to simulate the actual situations of strip steel production line, and study CCD inspection technology for the surface of strip steel in the laboratory. The testing platform is installed with a conveyor table, which can clamp 300mmx300mm sheets of different thickness, and make rectilinear motion steadily at a high speed, with the uniform motion distance of greater than 300mm, and uniform speed of up to 200m/min. The light source and camera equipment are arranged around the testing platform, and the angle of light source and the distance between light source and test specimen are adjustable; the angle of photography instrument and the distance of the test specimen are also adjustable. The equipment has been used by Baosteel Research Institute.

Currently, the users have increasingly high demand for the quality of strip steel (in particular automobile sheet) surface, and the steel mills adopt CCD to detect the quality of strip steel surface in general; however, it is required to grind the surface of strip steel manually before CCD detection so as to expose the surface defects fully. To this end, the Company designed an automatic grinding device specifically, which adopts two-side elastic compression while grinding based on the user's requirements to grind the strip steel from both sides, drags the grinding head with two coordinates (X,Y) numerical control system to simulate manual grinding track and route, thus grinding the surface of strip steel automatically. The device has been applied in 208 units of Baosteel successfully.
This equipment is used to keep the steel roll warm, and make its temperature decline linearly, solve the problem in rapid decline of temperature, and reduce cracks on the edge and improve the yielding rate. The equipment has been applied by Baosteel successfully.
The mandrel straightening measuring system is composed primarily by guide rail, pinion and rack, measuring trolley, sensor bracket, AC servo motor, laser displacement sensor, integrated controller, industrial computers, etc., which is installed on the hydraulic straightening pressure machine, and the laser displacement sensor points to the surface of mandrel, and controls the computer and servo motor to drive the measuring trolley and sensor for uniform linear motion; the sensor scans the surface of mandrel constantly, which can record the offset data of mandrel surface accurately through one cycle of scanning, and then calculate the coordinates of the maximum bending points and offset after processing. It is possible to network with the straightener during the production, so as to improve the production efficiency and product quality, and provides an effective, objective, high-precision evaluation standard for measuring the straightness of mandrel. Straightness measurement precision: ≤ 0.5mm/m (full length≤2mm), (regardless of the deformation of press body). The equipment has been applied in Baosteel Changzhou Roller Co., Ltd. successfully.
In order to avoid edge crack of cold-rolled steel coil (in particular for silicon steel coil) during uncoiling and edge cutting from affecting the quality of product, it is required to heat the edge of steel coil on the cold-rolled finishing production line, ensuring the edge of steel coil can reach a certain temperature during the uncoiling and edge cutting The equipment uses the mechanical arms with self-designed speed and controllable track to drive two heating plates to heat the two ends of steel coil (each heating plate is installed with 6 nozzles), and detects the flame size, heating time, operating trajectory and temperature of steel coil end in real time, and regulate the heating temperature automatically to meet the requirements for uncoiling the steel coil. Generally, the heating temperature can reach up to 80-100℃ for the range of edge of 60mm in width. The equipment has been put into operation in 1580 production line of Baosteel.

It is mainly used on hot-rolled finishing and leveling unit, whose upper and lower supporting roll are installed with roller wiping unit, so as to clean the oxidized iron scrap on the surface of supporting roll and keep the roller surface clean. The unit is installed on the archway at the outlet of temper mill, and the wiping head is compressed on supporting roll surface via the hydraulic cylinder, synchronize the toothed pulley by motor drive when working, so that the ball-screw nut mechanism could move horizontally to scrub the entire length of roll surface. The equipment uses two cylinders to swing the wiping belt, and to wipe the iron oxidized powder and oxide skin on supporting roll. The wiping belt can be tensioned and replaced by two hand-wheels arranged at top and bottom manually. The ball-screw nut mechanism is installed with a telescopic shield. A dust removal system is used to collect the removed iron oxidized scrap.
