Abstract: A multi-procedure integrated automatic production line for hard alloy blades under robot control is provided. The production line includes a rail-guided robot. A cutter passivation device and a blade cleaning and drying device are arranged on one side of the rail-guided robot. A blade-coating transfer table, a blade coating device, a blade boxing transfer table, a blade-tooling dismounting device and a blade boxing device are sequentially arranged on another side of the rail-guided robot. The blade-tooling dismounting device is arranged on one side of the blade boxing transfer table. The production line further includes squirrel-cage toolings for carrying the blades. The squirrel-cage tooling that are loaded with the blades can run among the cutter passivation device, the blade cleaning and drying device, the blade-coating transfer table and the blade boxing transfer table. The blades after being treated through the blade-tooling dismounting device are sent to the blade boxing device.

Abstract: A carbonaceous substance powder gasification system and gasification method. The system comprises a carbonaceous substance reaction apparatus and a gas return apparatus used for raising the pressure of some of a raw syngas cooled and preliminarily purified downstream of the reaction apparatus, then blending with high-temperature raw syngas upstream of the reaction apparatus and reducing the temperature.

Abstract: The present invention provides a method and a system for improving the precision of element measurement based on laser-induced breakdown spectroscopy. The method comprises: press-forming a sample to be measured with a tablet press; making a cavity on or immediately above a surface of the press formed sample; forming a layer of aerosol immediately above the surface of the sample to be measured with the components thereof completely identical to those of the sample to be measured; testing the sample to be measured by using a laser-induced breakdown spectroscopic system, so as to obtain the intensities of the characteristic spectral lines of a target element in the sample to be measured; and determining the concentration of the target element in the sample to be measured according to a calibration curve of the target element in prearranged calibration samples.
