The invention belongs to the technical field of metal surface processing, an particularly relates to an electrophoresis technology after galvanizing. The electrophoresis technology comprises the following steps that pre-processing is conducted, specifically, an alloy workpiece is sequentially subjected to oil removing, hot washing, rust removing and cold washing, and is subjected to physical activation and chemical activation; mold manufacturing is conducted, specifically, the alloy workpiece after activation is subjected to galvanization and phosphorization, and then is immersed in phosphorization to conduct anodic electrophoresis processing to obtain mold workpiece; and post-processing is conducted, specifically, the mold workpiece is subjected to clean water washing, cold washing and drying to obtain an alloy workpiece finished product. When an electrophoresis coating is formed at the alloy workpiece, the workpiece is cathode, and anodic dissolution does not occur, and therefore theworkpiece surface and a phosphating film can be protected from being damaged. The alloy workpiece surface is subjected to galvanization and phosphorization, and then the electrophoresis coating is applied, and therefore the metal can be protected. The paint is of high price and high quality, the anti-corrosion performance is high, the weather-proof performance is high, and the environmental protection performance is high.

The invention relates to a platform and method for monitoring a ground test launch control system. The method comprises reasonably planning a ground single machine and cable network layout; acquiringthe display images of a status display and a central computer display, and the status image of a test launch control device panel; identifying a currently executed process step; calling a corresponding template from a template; performing matching; and determining that a current test status is normal if matching is successful, or giving an alarm if not. The platform rearranges cable positions by acable arrangement box, is provided with a wire duct, and is provided with an independent wiring space to help the concentration of respective single machines of a test launch control system and a monitoring and operation panel. The platform and method perform comprehensive judgment by identifying a first word and a color block length, ensure the accuracy of process identification, obtain the corresponding template through the process, and ensure the accurate monitoring of the device state by the matching of the template.

The invention discloses a furnace refractory brick conveying and building process of a circulating fluidized bed boiler and equipment of the furnace refractory brick conveying and building process andbelongs to the field of refractory material construction processes and equipment. The furnace refractory brick conveying and building process of the circulating fluidized bed boiler is characterizedby comprising three steps of conveying, brick pushing and beating. The special equipment for the process comprises a main rack, a brick conveying device, a brick pushing device and a beating device. The brick conveying device is arranged between the beating device and the brick pushing device. The brick pushing device can push building materials on the brick conveying device to the position wherethe building materials are needed, and then the beating device can beat the building materials compactly. By means of the furnace refractory brick conveying and building process of the circulating fluidized bed boiler and the equipment of the furnace refractory brick conveying and building process, the building construction efficiency of refractory bricks in the building process of the circulatingfluidized bed boiler can be greatly improved, the automation degree is high, and labor is remarkably reduced.

The invention discloses a leveling device for manufacturing a body of a stress-relieving high-speed rail vehicle group, which relates to the technical field of high-speed rail production. A feeding box is arranged on the top of the right side of the feeding box, the inner two sides of the feeding box are connected with a limit push component, and the inner side of the limit push component is arranged with a steel plate of the vehicle group. In the present invention, the vertical arrangement of the upper leveling components is the same as that of the lower leveling components, and can be combined into a straight line with the same radian as the lower leveling components through the working energy of the second hydraulic cylinder. When leveling, the steel plate of the train group can be leveled into a steel plate with a specified radian. Because the high-speed rail body considers the wind resistance, most of them have a certain radian. All the required steel plates of the vehicle group are flattened into the required shape, which is beneficial to improve the flexibility of the equipment.

The invention discloses a method of repairing the adjacent sides of a dental crown in a 3D tooth model, comprising the following steps: extracting a boundary point set of a tooth model from a database; extracting left and right adjacent side boundary point sets of the tooth model from the boundary point set; and for both the left boundary and the right boundary, performing the following steps: interpolating points between the begin and end points of the left or right boundary according to a certain distance to get a closed-loop boundary point set; calculating the center of mass of the closed-loop boundary to make the closed-loop boundary point set gather to the center of mass so as to interpolate a point set V; generating a triangular face set based on the closed-loop boundary point set and the point set V; and calculating the center of mass of the tooth model, and adjusting the position of the point set V according to the center of mass to make the position consistent with the curvature trend of the tooth model. The contact relationship of the adjacent sides of adjacent teeth partially missing due to tooth segmentation can be restored accurately.

The invention provides a strip-penetrating broken-bridge heat insulation building energy-saving section bar and a machining process for the section bar. The section bar is formed by single section bars at the inner side and the outer side and a hollow heat insulating strip between the two section bars, the hollow heat insulating strip is in bilateral symmetry centering on a vertical center line, one ends of tooth supports, adjacent to compression tooth rolling torsion surfaces, inwardly incline towards the direction of the vertical center line, included angles are 1 degree to 2 degrees, and compression tooth support surfaces are vertical to the vertical center line. According to the section bar, the cost is reduced, the machining is convenient, the section bar formed by machining is not deformed due to machining, standard-structure section bars capable of preventing structural deformation can be obtained via rolling combination of the single section bars, and the installation problem of the section bar due to deformation in a combination process is eliminated.
