The structure and working principle of the devices for melting point measurement by means of thin film comparative method of cryoscopy were introduced.
The variation laws of blast volume,blast pressure,recarburizing rate and silicon loss were studied during the melting process of 5 t cold blast cupola.
During the process of converter steelmaking,the oxidbillity of slag had an direct influence on the speed of melting slag,the viscosity of slag and the extent of sputter.
The illinium electrode produces a slim arc when used in welding.With a high level of compression, it has a bigger melting depth in medium and high currents.
In order to increase water speed and turbulivity in ice-storage tank of direct evaporating and external melting ice-on-coil system, cambered baffles are installed in the ice-storage tank.
