Background
The ladle hot repair is an important process link for maintaining and repairing the ladle in the steelmaking process, is responsible for connecting a converter, a refining furnace and a ladle transfer station of a continuous casting process, and has high operation rate and compact operation time. The traditional ladle hot repair is divided into a fixed type structure and a movable type structure. Fixed is fixed in ground with the dust excluding hood, and the two relatively fixed in position of heat repair dust excluding hood and ladle, and this kind of form leads to the handling space of ladle to receive the restriction, and in the ladle can not stretch into the dust excluding hood moreover, lead to the dust removal effect unsatisfactory. The portable dust excluding hood can remove along the guide rail direction, and the guide rail direction is on a parallel with the ladle, and in order to reduce the hot repair station and take up an area of, the distance is nearer between the hot repair station, and a plurality of ladle sharing one or several dust excluding hoods leads to always having ladle hot repair station idle, and hot repair is inefficiency. And dust removal roofs are arranged on the roofs of steel making workshops in some steel mills, but the dust removal efficiency is low due to the fact that the dust production points are too far away, the investment is huge, and the overall effect is unsatisfactory. The most important contradiction in controlling the ladle hot repair flue gas at present is how to solve the problem that the ladle hot repair production process interferes with the flue gas trapping cover.
The problems existing in the traditional ladle hot repair process are as follows:
the smoke pollution generated in the processes of burning eyes and cutting and cleaning is serious;
the fixed dust hood cannot travel right above the steel ladle, so that the dust removal efficiency is low;
the traditional movable dust hood cannot simultaneously consider all steel ladles, so that steel ladle hot repair stations are idle, and the hot repair efficiency is low;
the dust removal roof has low dust removal efficiency because the overhead traveling crane runs frequently and the dust accumulation cover of the roof is difficult to be arranged near the steel ladle;
the whole worker is in a high-temperature environment.
