Detailed Description

The present application is described in further detail below with reference to figures 1-3.

Example 1

The embodiment of the application discloses an iron runner skimmer. As shown in fig. 1, the iron runner skimmer comprises a slag blocking member 1 and a lining member 12, wherein the slag blocking member 1 and the lining member 12 are both made of aluminum silicon carbide material by casting, a sinking groove 11 is arranged in the slag blocking member 1, the lining member 12 is inserted in the sinking groove 11, and a limiting mechanism 2 used for supporting the slag blocking member 1 is arranged on the lining member 12.

Limiting mechanism 2 includes dead lever 21, and dead lever 21 links to each other with inside lining component 12 through the built-in fitting, and dead lever 21 parallel position is in pushing off the slag component 1 top, and dead lever 21 length is greater than heavy groove 11 length, and the both ends of dead lever 21 all are located outside heavy groove 11.

The built-in fitting includes two spacing muscle 22, and two spacing muscle 22 are all buried underground in inside lining component 12 and parallel with heavy groove 11 length direction, and two spacing muscle 22 highly uniform all the vertical fixation have branch 23 on two spacing muscle 22, and two branch 23 wear out inside lining component 12 outside and with dead lever 21 fixed connection.

The slag stopping component 1 is cast and fixed in an iron runner, and when molten iron flows through, the slag stopping component 1 stops scum on the molten iron, so that the scum iron is separated from the slag iron; when pushing off the slag component 1 and use for a long time and make the bottom damage, 11 bottoms of heavy groove spill, and inside lining component 12 descends automatically under self action of gravity, drives dead lever 21 and supports on pushing off the slag component 1, and inside lining component 12 lower extreme flushes with pushing off the slag component 1 lower extreme this moment, mends the damaged part of pushing off the slag component 1 for the pushing off the slag function of skimmer can continue to use, need not to demolish the skimmer is whole, has saved iron runner repair time and the prosthetic required material of skimmer.

There is the clearance between

inside lining component

12 and 11 cell walls of heavy groove, and pushing off the slag component 1 upper berth is equipped with the cotton 4 that keeps warm, and the cotton 4 that keeps warm covers the clearance between inside

lining component

12 and 11 cell walls of heavy groove, and the cotton 4 both ends of keeping warm all are taken on the iron runner simultaneously, and branch 23 passes the cotton 4 that keeps warm. The lining component 12 can move freely through the width of the gap, and the heat insulation cotton 4 plays a role in stopping sundries from falling into the sink groove 11, so that the lining component 12 can descend smoothly. In addition, the clearance between lining component 12 and heavy groove 11 has the effect that buffering lining component 12 and pushing off slag component 1 material receive the thermal stress effect, and heat preservation cotton 4 covers lining component 12 and pushing off slag component 1 again, has played the heat preservation effect, has reduced lining component 12 and pushing off slag component 1 and when external direct contact because the difference in temperature is too big, leads to the possibility that the material produced the crack.

As shown in figure 2, two parallel lifting hooks 3 are arranged on the slag stopping component 1, one end of each lifting hook 3 is embedded in the slag stopping component 1, the other end of each lifting hook 3 upwards penetrates through the heat insulation cotton 4, and the lifting hooks 3 are parallel to the supporting rods 23. During the construction, the operator accessible lifting hook 3 hangs slag stopping member 1 and puts into the iron runner, pours the iron slag component again fixedly, provides convenience for slag stopping member 1's removal.

Example 2

Referring to fig. 3, the difference between this embodiment and embodiment 1 is that a threaded sleeve 5 is embedded in the slag bridge 1, one end of a hook 3 is screwed into the threaded sleeve 5, the other end of the hook is located outside the slag bridge 1 and vertically penetrates through a fixing rod 21, adjusting nuts 51 are screwed onto both hooks 3, and the two adjusting nuts 51 are located below the fixing rod 21.

When the bottom end of the slag stopping component 1 is damaged to enable the lining component 12 to descend, the fixing rod 21 is supported on the two adjusting nuts 51, the moving distance of the lining component 12 is limited, an operator can adjust the relative positions of the lifting hook 3 and the adjusting nuts 51 according to actual design requirements, the movable range of the lining component 12 is increased, meanwhile, after the lower end of the lining component 12 is damaged, the operator can realize the purpose that the lining component 12 falls down again by screwing the adjusting nuts 51 to move downwards, the slag stopping function of the slag skimmer is continuously maintained, and the maintenance time and cost of an iron runner are reduced.

The above embodiments are preferred embodiments of the present application, and the protection scope of the present application is not limited by the above embodiments, so: all equivalent changes made according to the structure, shape and principle of the present application shall be covered by the protection scope of the present application.
