It is analyzed that high total energy consumption,low degree of fractionation for crude oil,insufficient yielding of vacuum distillation,undesired operating condition in electric desalting section and the unit corroded in operation of the atmospheric and vacuum distillation unit.

Making straight line on the single logarithm coordinate, n_d is the slope of the straight line, which express the drawing hardening rate of the dual phase steel wire.

Test Research on Solid Boronization of Internal Die for Cold-drawing of Steel Tube

The paper concerns the process parameters of continuous casting and cold-drawing of 12Cr2MoVWTiB seamless steel pipe for high pressure boiler,proposes the feasibility of produced high pressure boiler pipe of 12Cr2MoVWTiB steel by continuous casting billet,the surface quality and mechanical properties of the boiler pipe can meet the demand of standard GB5310-1995.

It also provides the basic information for the optimization of roll' s diameter in cold-drawing techniques.
