Specific embodiment
The utility model provides a kind of slag blocking plate of converter and converter, solves the problems, such as to be not easy to maintenance, shorten more
Slag blocking plate of converter and maintenance time are changed, converter producing efficiency is improved.
In order to make those skilled in the art more fully understand technical solution provided by the utility model, below in conjunction with attached
The utility model is described in further detail with specific embodiment for figure.
Please refer to Fig. 1-Fig. 5, a kind of slag blocking plate of converter provided by the utility model, including staggered floor overlapped upper layer converter gear
Slag plate and lower layer's slag blocking plate of converter.It is overall structure that existing slag blocking plate of converter, which is substituted, in this programme, in replacement and scarfing cinder maintenance
The technological deficiency of integral demounting is needed, each piece of overall structure of slag blocking plate of converter is now changed to two-piece unit structure, faying face is adopted
Upper layer converter gear is only dismantled when slag blocking plate of converter position is corroded by steel slag, and accumulation seriously needs to clear up with staggered floor bridging arrangement
Slag plate, lower layer's slag blocking plate of converter do not have to generally dismantle, and replacement is solved the problems, such as to be not easy to maintenance, be shortened more
Slag blocking plate of converter and maintenance time are changed, converter producing efficiency is improved.
Preferably, the faying face between upper layer slag blocking plate of converter and lower layer's slag blocking plate of converter is inclined-plane, between two inclined-planes
With default gap.Specifically, the default gap of faying face can be 4mm, and for compensating thermal expansion, this staggered floor bridging arrangement is just
It glides in steel slag along slag blocking plate of converter, without being flowed on the inside of slag blocking plate of converter from gap.
Preferably, it is provided with reinforcing rib 5 on upper layer slag blocking plate of converter and/or lower layer's slag blocking plate of converter, reinforcing rib 5 uses net
Shape gusset.
In addition, including slag blocking plate of converter 3 and being set on slag blocking plate of converter 3 disclosed herein as well is a kind of converter
Bolt 4, and the slag blocking plate of converter 3 is slag blocking plate of converter 3 disclosed in above-described embodiment, therefore, with the chain riveting machine
Vehicle also has above-mentioned all technical effects, and this is no longer going to repeat them.
Preferably, the bolt head of bolt 4 is located at 3 inside of slag blocking plate of converter.Bolt 4 and the connection of slag blocking plate of converter 3 are changed to
Under put on locking structure, i.e., bolt head tightens bolt 4 in 3 outside of slag blocking plate of converter in 3 inside of slag blocking plate of converter, nut.It improves
Before, bolt penetrates on the outside of slag blocking plate of converter, and nut, when replacing slag blocking plate of converter, cuts off top on the inside of slag blocking plate of converter
After bolt head, because lower nuts do not loosen, screw rod cannot fall off in time, be not easy to dismantle；After improvement, bolt 4 is kept off from converter
It is passed through on the inside of slag plate bracket, nut on the outside, cuts off nut rear bolt 4 and falls off under Gravitative Loads, easily removes.Design changes
Slag blocking plate of converter after, it is easy for assemble or unload, a large amount of non-cutting times have been saved, converter producing efficiency is greatly improved.
Preferably, 3 outer wall of slag blocking plate of converter and vertical direction tilt angle are 30 ° -50 °, molten steel, steel under this tilt angle
Slag is more easy to fall off.
Aiming at the problem that slag blocking plate of converter design is not easy to maintenance, it has been decided through consideration that whole by each piece of slag blocking plate of converter
Body structure is changed to two-piece unit structure, and slag blocking plate of converter connect bolt with bracket and is changed to down put on locking structure, after improving in this way, greatly
Replacement slag blocking plate of converter and maintenance time are shortened greatly, improve converter producing efficiency.
