Description
Technical field
The utility model relates to steel and iron manufacturing, in particular to a kind of cupola well of section hot-blast stove.
Background technique
Hot-blast stove is the important equipment of melting iron in Foundry Production, is poured into sand mold after casting pig is fused into molten iron
In after cooling unpack obtain casting.Hot-blast stove is a kind of vertical cylinder-shaped smelting furnace, is divided into forehearth and rear furnace.Furnace divides again afterwards
For three parts, furnace, waist furnace and cupola well are pushed up.Waist furnace and bustle pipe separate, and repair furnace and close later, are sealed with mud.It pushes up on furnace
It is heat exchanger.It is mainly used for iron casting production, also to cooperate pneumatic steelmaking, because of furnace roof opening upwards, therefore claims hot-blast stove.
Notification number is that the Chinese patent of CN203024569U discloses a kind of hot-blast stove slag-draining device, including is used for and furnace body
The shell of assembly is provided with slag releasing channel in the shell, and cavity is provided in the shell, is slagged tap described in the cavity cladding
Channel, the cavity are provided with inlet and outlet, and the water inlet and the water outlet are connected to the cavity respectively.
This hot-blast stove slag-draining device by setting cavity in shell, in conjunction with inlet and outlet so that liquid from into
The mouth of a river enters cavity and flows in cavity, takes away the heat of shell and slag releasing channel, is then flowed out by water outlet, can be to slagging tap
Channel cools down, and effectively reduces high temperature furnace slag melting loss caused by slag releasing channel, it is no longer necessary to often replace slag-draining device.
But this slag-draining device is the service life for extending slag releasing channel, is suspended in the scum of liquid surface still
It does not effectively remove, can enter in sand mold with liquid, so that casting the defects of there are stomatas, crackle, reduces casting
Quality.
