Abstract

The invention provides a method for collecting surplus heat of iron alloy pouring, which can not only effectively cool alloy pouring ingot (temperature range: 1250-200 DEG C), but also can furthest recover heat energy in the alloy pouring ingot, and obtain better dust-removing effect, therefore, the invention also provides a special device of the method for collecting the surplus heat of the iron alloy pouring. The method is characterized in that heat energy in the alloy pouring ingot is directly sent into a heat pipe steam generator through an insulating flue by using a high-temperature resisting catching cover, the heat pipe steam generator realizes heat exchange and produces steam, and smoke out of the heat pipe steam generator is discharged into air after dust is removed by a dust remover. The special device comprises a smoke catcher which is connected with the heat pipe steam generator, and the heat source output end of the heat pipe steam generator is connected with the dust remover.

Description

(1) Technical field [0001] The invention relates to a method for collecting waste heat of alloy casting, and also relates to a method and special equipment for collecting waste heat of ferroalloy casting (2) Background technology [0002] The temperature of the alloy casting is very high, generally around 1250 °C. At present, the method of direct cooling is usually used to reduce the temperature of the alloy ingot to below 200 °C. The pure cooling makes a lot of heat energy in the alloy ingot wasted. (3) Contents of the invention [0003] The object of the present invention is to overcome the above-mentioned defects and provide a method for collecting waste heat of ferroalloy casting, by which not only can the alloy casting ingot be efficiently cooled (temperature range of 1250 ℃ ~ 200 ℃), but also the thermal energy in the alloy casting ingot can be recovered to the maximum extent, In addition, a better dust removal effect is obtained. Therefore, the present invention al...
