Abstract
The utility model discloses a novel nickel matte chute, which is formed in the manner that a chute body is arranged in a steel shell; the chute body is a graphite chute; the joint of every two sections of adjacent graphite chutes is connected through an L-shaped son buckle and an L-shaped mother buckle, which are matched with each other; and an unshaped fiber refractory material is filled and rammed between the graphite chutes and the steel shell. In the novel nickel matte chute, according to the characteristics that the quality of nickel matte in a top-blown furnace is high and copper strap slag are more and easy to bond, the present nickel matte brick chute is improved into the graphite chute; a cast iron chute between the chute and a receiving port on the original chute structure is removed, the specifications of the graphite chutes are unified from the receiving port to a big-end chute, the building method is changed, the graphite is combined with the unshaped fiber refractory material to be rammed, and in order to eliminate the gaps among the graphite chutes, the joint of the two sections of the chutes is connected by a male buckle and a female buckle. The workload of workers in front of the furnace is remarkably reduced, the operation rate of a top-blown furnace is improved, the maintenance is convenient, and the potential safety hazards are eliminated.
Description
Technical field
This is novel to belong to field melt blowdown system such as nonferrous metallurgy, particularly a kind of novel nickel matte chute.
Background technology
After the top blast furnace system is gone into operation; Top blast stove stokehold discharging difficulty is one of problem that influences the operating rate raising always; Wherein 1#, 2# and 3# nickel matte brick chute are easy in the sulfonium discharge process because of the dead groove of bonding; Not only need a large amount of manpowers to remove to clear up chute in this case, waste time and energy, worse situation possibly cause stove can use the underproduction even stopping production because of no chute.
On the other hand; Because the seepage force of nickel matte is more intense; Even the new brick chute brickwork joint of building soon also can become big gradually because of the infiltration of sulfonium; Even more serious situation is that the nickel matte that pierces brickwork joint can be raised distortion with whole chute outer leaf, and final result causes chute to run copper exactly, even causes bigger secondary accident.
Can see that from above two situation brick output nickel matte chute not only can not meet the needs of production aspect the life-span, need often build by laying; Nor economical, the aluminum-carbon brick that is etched has been damaged in scale removal process basically, and chute of every block just needs to replenish a large amount of new bricks; The more important thing is with brick nickel matte chute has higher potential safety hazard, and production and installations and facilities even the person are had certain threat.
The utility model content
The purpose of the utility model provides and a kind ofly is not easy to cause dregs to bond in chute walls, reduces nickel matte and infiltrates chute, the novel nickel matte chute of avoiding industrial accident to take place.
For realizing above-mentioned purpose; The solution of the utility model is: a kind of novel nickel matte chute; By being set in the box hat, the chute body forms; Said this chute body is the graphite chute, and the junction of said adjacent two arthrolith China ink chute is that suitable L shaped double buckle connects, and filling ramming between said graphite chute and the box hat has indefinite form cellulosic refractory materials.
Adopt above-mentioned novel nickel matte chute; Of high grade according to top blast stove nickel matte, the copper strips slag is higher and characteristics such as easy bonding, existing nickel matte brick chute makes the graphite chute into, on original chute structure, the cast iron chute between chute and the receiving port is removed; Unify graphite chute specification from receiving port to major part chute; Change building method and add the amorphous refractory ramming with graphite, for eliminating slit between the graphite chute, the box and pin connection has been designed in two joint chute junctions.Obviously reduce post, stokehold worker's workload, improved top blast stove operating rate, made things convenient for maintenance, more eliminated potential safety hazard.
