The collapsibility of the sodium silicate dolomite sand is controlled by the size, wall, pouring temperature, capacity for sand and draw time of the cast.
The influence of melting rate, super heating temperature, pouring temperature and modification on high chromium cast iron were researched.
The higher the pouring temperature and initial mold temperature are, the larger the plastic strain while the smaller the thermal stress is.
Proper decrease in pouring temperature and increase in shell mold temperature are helpful to preventing hot tear.
The effect of trace elements in ZA27 cast alloy, such as Mg, Cu, re, ti and thickness of. castings, pouring temperature, modification on the solidification characters of ZA27 cast alloy were studied.
The higher the pouring temperature or the larger the sprue hollow area rate is, the faster the filling velocity of molten aluminum is.
The melting speed, overheat temperature, pouring temperature and modification in production of high chrome cast iron were studied.
In this paper the effects of pouring temperature, mold temperature, inoculants, and section size on the microstructure and mechanical properties of casting nickel-base superalloy K24 were studied.
At proper pouring temperature and mold temperature, the effect of die casting speed and pressure on microstructure and properties of AM60B alloy has been studied.
