Description

Blast furnace stokehole slag runner clearance instrument and crane

Technical Field

The utility model relates to a, in particular to a blast furnace front slag iron runner cleaning tool and a crane.

Background

With the development of the modern blast furnace tapping technology, the blast furnace tapping system is continuously optimized and perfected, the pressure in the blast furnace is continuously increased, the tapping quantity of a tapping field is increased, the quantity of iron slag is also increased during tapping, the iron slag of the blast furnace is a high-temperature by-product generated in the blast furnace iron-making production process, and the existing treatment method of the super-huge blast furnace iron slag is mainly wet treatment, namely water slag treatment.

A No. 3 blast furnace of the first Steel works Limited company is a 4000-cubic-meter-scale super-large blast furnace, and is provided with four casting places, an iron runner and a slag runner are all cast by using casting materials, refractory bricks are built in a steel groove, then a mold is fixed for casting treatment, when the bottom of the iron runner and the slag runner is eroded to a permanent layer (about half of the thickness of the first casting) which is generally 25 ten thousand tons of iron output of the casting places, periodic repair is carried out once, the use of the casting places is stopped after the slag runner is eroded to the permanent layer after each stopping and pouring period is about 90 days, residual iron is discharged, the iron runner and the slag runner are beaten to a pitted surface by using tools such as a hook machine, a pneumatic pick and the like, the scrap iron and the residual materials are cleaned, and the mold is stacked for casting again.

The quantity of the iron slag to be processed in the iron slag runner daily is large, the length of the iron slag runner is long, a heat-insulating cover plate is usually covered on the iron slag runner, and along with the current environmental protection requirement, the dedusting wind power also has to be improved to cause the upper layer of iron slag to be gradually cooled and solidified in the iron slag runner in the iron tapping process (the iron slag has large viscosity and slow circulation and is another reason for causing the upper layer of iron slag to be solidified), and the lower layer of iron slag to be circulated. In order to ensure the liquidity of the slag iron runner, a solidified layer at the upper part of the slag iron runner is usually needed to be smashed by tools such as an air pick, a large hammer drill rod and the like in the tapping clearance time, firstly, the liquidity of the slag iron during tapping is ensured, secondly, 2-3 times of local repair work is usually needed to be carried out on the slag iron runner which is seriously corroded locally in the period of 90 days in the tapping time, and the solidified layer is required to be cleaned regularly because the slag iron runner cannot be detected whether to be corroded to a permanent layer or not because the upper layer is completely covered by the solidified slag iron. Generally, about 60 minutes is needed for 3 people to clean once by adopting tools such as an air pick, and due to the fact that operating personnel are required to operate nearby a slag iron runner, the operating environment is severe, and scalding and sunstroke accidents are easy to happen.

FIG. 2 is a side view of the blast furnace forehearth slag runner cleaning tool of FIG. 1.

Detailed Description

Referring to fig. 1-2, an embodiment of the present invention provides a blast furnace front slag runner cleaning tool, including: a connecting piece 1 and a spear hook 2.

The lance hook 2 includes: a connecting plate 2-1 and two hook plates 2-2.

The first end of the connecting plate 2-1 is connected with the connecting piece 2.
