, splash big using ladle-to-ladle temperature drop is serious etc..
Summary of the invention
The purpose of this utility model is to provide a kind of bottom blowing stirring device for producing manganese iron, ferrochrome, overcome shaking ladle and
The shortcomings that ladle-to-ladle method, bottom blowing stirring can accurately control the reaction speed at slag liquid interface, while rapid reaction being allowed to reach balance.It can
Significantly to reduce production cost, production efficiency is improved, securely and reliably, while bottom blowing tolerance is controllable, can accurately control life
Produce rhythm.
The utility model mainly includes bottom blowing gas vavle shelf and bottom blowing circumferential weld pipe composition, as shown in Figure 1, bottom blowing gas vavle shelf
Including hand off valve 1, first pressure transmitter 2, flowmeter 3, regulating valve 4, second pressure transmitter 5, pneumatic cut-off valve 6,
Fire arrester 7, hand off valve 1, first pressure transmitter 2, flowmeter 3, regulating valve 4, second pressure transmitter 5, pneumatic cutting
Valve 6, fire arrester 7 are successively connected by stainless steel tube, by connection by metal hose to bottom blowing circumferential weld pipe 9 after fire arrester 7, bottom blowing circumferential weld
Pipe 9 is evenly distributed in resistance to material 8.
When bottom blowing stirring device works, gas successively passes through 2 → flowmeter of hand off valve 1 → first pressure transmitter 3
It is molten to eventually enter into ladle for → regulating valve 4 → second pressure transmitter 5 → pneumatic cut-off valve, 6 → fire arrester, 7 → bottom blowing circumferential weld pipe 9
Pond.
As shown in Fig. 2, resistance to material 8 is embedded with bottom blowing circumferential weld pipe 9, bottom blowing circumferential weld pipe 9 is evenly distributed in resistance to material 8；Bottom blowing
9 outermost diameter of circumferential weld pipe is generally 5~10mm, and circumferential weld spacing is 1~2mm, due to being circumferential weld structure, it is not easy to block.
This agitating device has the function of that nozzle leads to again, can be with when ladle furnace bottom goes up or spray gun is blocked, in the short time
It is blown into oxygen or air, is reacted by oxygen or air with the carbon in Fe alloy slag in ladle, high temperature is generated, to lead to again.
This agitating device is operated using computer remote, reduces shaking ladle, ladle-to-ladle working strength.
Ladle bottom arranges the resistance to material of 6~12 blocks of embedded bottom blowing circumferential weld pipes according to ladle size, is embedded in every block of resistance to material
