A system for reducing slag accumulation and steady flow in zinc pot rolls

Abstract

The invention discloses a system for reducing zinc pot roller accumulated slag and stabilizing flow. The system comprises a separating plate arranged in a zinc pot, the separating plate is arranged between the rear side surface of a furnace nose and the inner wall of the zinc pot, the separating plate comprises a first slab part, a second slab part and a third slab part, the first slab part extends in the width direction of the zinc pot, the two ends of the first slab part in the width direction of the zinc pot are the first end and the second end, and the first slab part is provided with a first side surface facing the rear side surface of the furnace nose and a second side surface facing the inner wall of the zinc pot; at the first end, the second slab part obliquely extends from the first side surface of the first slab part to the rear side surface of the furnace nose; and at the second end, the third slab part extends from the second side surface of the first slab part to the innerwall of the zinc pot. According to the system for reducing the zinc pot roller accumulated slag and stabilizing flow, through arrangement of the separating plate, the influence of a zinc slag flow field in the zinc pot on an alloy layer in a sinking roller ditch groove is eliminated, and thus the problem of separation of suspending slag and zinc slag discharged by a liquid zinc pump due to the temperature difference of zinc ingots is solved, and the growth of a sinking roller surface alloy layer is accelerated.

Description

technical field [0001] The invention relates to a system for zinc pots, in particular to a system for cleaning zinc slag from zinc pots. Background technique [0002] As an important equipment of the galvanizing line, the zinc pot plays an important role in the quality of the steel plate surface. However, due to the gradual consumption of the zinc liquid in the zinc pot during production, zinc ingots need to be continuously filled, and the new zinc ingots are kept at room temperature. Add it into the 450° zinc pot, so that the local temperature of the zinc liquid near the furnace nose is lowered, and it is easy to produce suspended slag particles of iron-zinc alloy within a certain range. The zinc liquid in the zinc pot produces disturbances, and the zinc slag flow field in the zinc liquid in the zinc pot is as follows: figure 1 As shown, the zinc-added area 1 is likely to produce suspended slag 2 due to the low temperature, which is brought to the sinking roll 3 to form an...

Problems solved by technology

[0005] The purpose of the present invention is to provide a system for reducing the slag accumulation and steady flow of zinc pot rolls. The system eliminates the influence of the zinc slag flow field in the zinc pot on the alloy layer in the groove of the sinking roll by setting partitions, thereby solving the problem of In the prior art, the separation of the suspended slag caused by the temperature difference of the zinc ingot and the zinc slag discharged from the zinc liquid pump accelerates the growth of the alloy layer on the surface of the sinking roll
