The estimated values of the MFE for several common and less common metals are listed in Table 7.1. The MFE values range from 28 109 J t 1 for steel slabs to 68400 109 J t 1 for refined gold bars. This wide range, indicating that the MFE values can differ by a factor of 2400, is a reflection of the widely different ore grades and the widely different processing technologies that are employed in the production of various metals. 

Steel slab from continuous caster or slab storage... 

Oxy-acetylene flame is a very useful tool in modem industry as it can cut through steel slabs and weld them together again. In the oxy-acetylene flame, oxygen and acetylene from separate cylinders are fed into a blow torch. The gases are mixed thoroughly and burnt at the tip of the blow torch. The products of this combustion are carbon dioxide, water vapour and heat. 

The heat released reaches 3000°C to 3500°C. As this temperature is well above the melting points of most metals, the torch is used for welding. For cutting steel slabs, the flame is directed to the steel slabs. A supplementary supply of oxygen is added to the flame by another jet which bums the steel slabs sending out a shower of sparks. This torch can be used under water also. 

Also available are numerous styles of hand made, high quality blades from Solingen and Sheffield a complete line of Russell Green River knives and a selection of laminated steel blades from Norway. These are made up of a core of razor blade hard steel for toughness, and an outer sandwich of two shock resistant steel slabs for flexibility and break resistance. ...

In Fig. 13.17, sensor array is shown for AE measurement on a welded section of a steel-slab connecting with a lateral beam. By appl5dng a ultrasonic test (UT), a crack was suspected at a location where the U-shaped rib plate was welded with the lateral beam. AE sensors were installed to locate sources around the stop-hole to arrest crack extension. 

A 1.5-tonne steel slab pendulum is suspended by a chain and allowed to fall and strike the front of the cab - a frontal impact of 4500 mkgf. This test evaluates mainly the strength of the steel cage (ECE Regulation No. 29) but strain gauges are also fitted to the SMC panels to observe failure patterns.

Effects of Crystallization of Mould Fluxes on Property of Liquid Slag Film and Its Impacts on Peritectic Steel Slab Continuous Casting... 

Three typical mould fluxes for peritectic steel slab continuous casting with different basicity used in commercial production were chosen and then prepared with chemical pure agents. CaO, Na20, MnO and Li20 were added as carbonates. The specific compositions were listed in Tabic I. 

As the changes of melting temperature and viscosity of post-precipitated liquid slag is not obvious, the discussion therefore focused on effects of crystallization on break temperature, crystallization temperature and lubrication property (Vi) of post-precipitated liquid slag. The effects of the property change on continuous casting of peritectic steel slab were also discussed.
