Introduction to Hualing Lianyuan Steel's improved raw material sampling system: after several months of program development and commissioning, recently, Hualing group Lianyuan Steel's bulk raw material and fuel quality sampling system has been officially put into operation, and the operation effect is good at present. In order to reduce the impact of human factors on the incoming quality of bulk raw fuels, and improve the randomness, pertinence and effectiveness of the physical quality spot check of bulk raw fuels

after several months of program development and commissioning, recently, the quality spot check system for bulk raw materials and fuels of Lianyuan Iron and Steel Co., Ltd. of Valin Group was officially put into operation. At present, the operation effect is good

in order to reduce the impact of human factors on the incoming quality of bulk raw fuels and improve the randomness, pertinence and effectiveness of the physical quality spot check of bulk raw fuels, at the beginning of this year, Lianyuan Steel started to organize the development of random sampling procedures. This system has changed the mode that the quality inspectors determine the inspection lot, vehicle number, vehicle number and spot check distribution scheme of the spot check of bulk raw and fuel materials such as mine and coal in the past. Through the application of random sampling procedures, the probability of successful sampling by general suppliers is 40%, and the probability of successful sampling by key monitoring suppliers is 100%, realizing the organic combination of random sampling and targeted sampling, The effect of quality spot check is improved

this tool cannot collide with the authenticity of mixer information. The spring testing machine completely cleans the force measuring cylinder and piston or polishes and replaces the cylinder or piston of the experimental force sensor. The following inspection methods are used: check whether the 220V power supply and microcomputer system power supply are normal if the switch is not displayed? If the fuse disconnection is not confirmed by China Construction machinery information, it is only for your reference. Please do not reprint without permission. If it has been used under this authorization, it shall be used within the scope of authorization, and "source: China Construction Machinery Information" shall be indicated
