表1 通道感应加热和等离子加热技术的优点和不足[4,5,15~21]
Table 1 Advantages and disadvantages of channel induction heating and plasma heating tundishes[4,5,15-21]
TechnologyAdvantageDisadvantage
Channel induction heatingHomogeneity;Larger size and occupation;
quick heating;tundish geometry dependent;
high heating efficiency up to 90%;cost for maintenance;
easy instrumentation；quality demand for refractory;
safe in service;special design for cooling and insulation of
easy maintenance;the heating coils
fine metallurgical effect
Plasma heatingQuick action for heating;Arcing and inert gas required;
good adaptability;larger temperature fluctuation locally;
less consumption for refractory;possibly arc extinction in service;
easy operation and maintenance;noise while in operation;
less occupation in sizesignal interference;
high local temperature for steel and refractory;
secondary oxidation;
lower heating efficiency about 60%
