A new coaxial cablethe SFX type semiflexible coaxial cable with tin dipped braid;

Based on double linear constitutive model of mild steel,damping force hysteresis loop models of the X-type and the triangle type mild steel dampers are derived from classic mechanical principle directly.

In this paper- the characteristics(including forming and bake hardening)of TRIP600 are measured- the feasibility of two parts using trip steel of 600 N/mm2 grade to replace mild steel is researched.

In this paper,using mild steel plate have stable hysteresis under loading and unloading repeated cycles,designed a U shape mild steel plate damper,an hysteresis loop and analytical model was carried out by experimental test At last,this damper is .

The influences of various isothermal hardening treatments on microstructure and properties of semi-steel made by quenching and isothermal hardening and forging,which contain 1.

During semi-steel smelting process,less silicon,manganese are oxidized making.

Improvement and effects of semi-steel steelmaking at Panzhihua Iron and Steel Group Company is presented with adopted measures, such as hot metal pretreatment, application of active lime for slagging, improvement and optimization of slagging process and control of end point of blowing, implementation of slag splashing and so on.

The effect of rare earth on impact fatigue property of cast semi steel was studied.

Effects of RE modification and heat treatment on carbide morphology and mechanical properties of cast semi steel were studied.

Effect of Austenitizing Condition on Hot Deformation Microstructrue of Semisteel;

In this article, the changes in mechanical properties of semisteel during its isothermalmaintaining processing after deformed are studied by means of the thermo-compressing of twiceintermittent loaded.

Against the problems existing in semisteel making,optimization test of slag making process is conducted with the result: shorten the beginning forming time,guarantee smelting smooth operation,get good effect.
