Technical field
The present invention relates to industrial solid castoff comprehensive utilization technique field, particularly relate to a kind of molten branch reduction modification stove external slag discharge hole structure, it can improve production operational availability in the reduction modification stove of realizing molten branch function, reduce equipment failure rate.
Background technology
In existing molten minute reduction furnace, adopt the band water jacket cooling structure that is similar to blast furnace ironmaking, control slag emission by the slag bot of stopper.
As shown in Figure 1, existing slag discharge hole structure comprises furnace shell 1 ' and slag notch cooler 2 ', is provided with refractory material 3 ' in the described furnace shell 1 ', and the inwall of described furnace shell 1 ' is provided with water-cooling wall 4 ', and described water-cooling wall 4 ' is positioned at the inboard of refractory material 3 '.Described slag notch cooler 2 ' is arranged in refractory material 3 ' and water-cooling wall 4 ', and is communicated with furnace chamber (right side of furnace shell 1 '), and slag notch cooler 2 ' is positioned at the inside of furnace shell 1 '.Wherein, slag notch cooler 2 ' is generally the cinder notch copper sheathing.
When needs dischargings slag, stopper is mentioned, high-temperature slag flows out from the passage of slag notch cooler 2 ', gone out slag after, operate stopper and block cinder notch.
Above-mentioned slag discharge hole structure is in actual production, and the situation that burns out the cinder notch copper sheathing takes place again and again, and reason mainly contains:
1, waste residue piece ferrous grade is low, and the quantity of slag is big, and cinder notch must be set.And the molten reduction furnace that divides requires operation with high pressure, and furnace pressure is big, promotes cinder notch and moves outward, causes damaging;
2, the molten iron manganese content that obtains is between 1.8～2.6%, and manganese content is higher, and the manganese content of respective slag is also than higher.The slag that the quantity of slag is big, manganese content is higher is more serious to the cutting of last cinder notch, also can cause damaging.
Summary of the invention
The objective of the invention is, a kind of molten branch reduction modification stove external slag discharge hole structure is provided, no longer adopt conventional water cooling copper sleeve structure, to avoid occurring the slag notch cooler burning phenomenon.
Above-mentioned purpose of the present invention can adopt following technical proposal to realize:
A kind of molten branch reduction modification stove external slag discharge hole structure, described slag discharge hole structure has slag notch shell, refractory material and water-cooled baffle, described slag notch shell is connected the outside of the furnace shell of described reduction modification stove, be provided with refractory material in the described slag notch shell, be provided with slag releasing channel in the described refractory material, described slag releasing channel is communicated with slag extracting channel in the reduction modification stove, and described water-cooled baffle is arranged between slag notch shell and the refractory material ringwise with centering on; Be filled with fire clay in the described slag releasing channel, when needs discharging slag, drill goes out slag flow channel in described fire clay, after waiting to discharge slag, fire clay is squeezed into slag flow channel stop up.
Aforesaid molten branch reduction modification stove external slag discharge hole structure; described water-cooled baffle comprises having water inlet pipe and outlet pipe; one end of described water inlet pipe is arranged on the below of water-cooled baffle; the other end of water inlet pipe passes and exposes from described slag notch shell; one end of described outlet pipe is arranged on the top of water-cooled baffle, and the other end of outlet pipe passes and exposes from described slag notch shell.
Aforesaid molten branch reduction modification stove external slag discharge hole structure, described slag notch shell is box hat.
Characteristics and the advantage of the molten branch reduction modification stove external slag discharge hole structure of the embodiment of the invention are: cinder notch does not have water jacket, with regard to fundamentally having solved molten minute reduction furnace because slag notch cooler damages the difficult problem of damping down again and again, has improved the operating rate of molten minute reduction furnace.
