technological requirements
1.The gemmological classification and fashioning properties and technological requirements are introduced systematically. The fashioning skills of faceted calcite stone are probed.
2.According to the characteristics and technological requirements of the substance obtained after dehydrogenating exo 2 camphanol made by hydration, 9 # catalyst is manufactured and better technological condition for post treatment is determined.
3.Based on the technological requirements of the condemning line and lim iting slot of railway wheels, the special cutting tools are designed, and two ki nds of tool design schemes are compared.
4.This paper introduces the technological requirements, control decision, design of hardware and software,digital simul. ation and operating situation of a computer AGC system in the 450 cold tandem mill with three mill hoursings.
5.Abstract: The technological requirements for mechanical back-up braking system and wheel-disk braking system applied on the magnetic levitation vehicles are described.The development and testing for the wheel-disk braking system are expounded.
6.The label of parts size must be tried to accord with the technological requirements to reduce the error. This article set the mark of shaft spares size as an example to study how to reduce the error.
7.Combined with the engineering example, it is to approach the application of SMW process pile on the basis of water gate, and put forward the construction technological requirements, quality control methods and quality inspection contents as well as the relevant achievements.
8.This paper introduces the trial and manufacturing process of ASTMC90300 tin bronze for buddha. According to smelting technological requirements, the alloy is prepared by a 100 kW intermediate frequency induction furnace, and a group of alloys of optimum mechanical property are selected by intersection experiments.
9.Abstract: The marine mooring chain steel (R4) has been developed through the composition design,heat-treatment performance investigation and pilot-plant test.Hot rolled bar has high tensile strength,high low-temperature impact value and good weldability,cold bendability and heat-treatment property over a wide range of quenching and tempering,which is fully enough to meet the technological requirements of producing chain and suitable for commercial chain manufacture.
10.Through experimental research on secondary mechanical autoffrctage of alumal,the results obtained in this paper fully prove that the secondary mechanical autoffretage technique as a kind of technological method to reduce mandrel push is useful and effective,this technique can meet the autoffretage requirements of thick-walled cylinders of different bore dismeters.
