Technical Field

The invention relates to the technical field of non-ferrous metal plate and strip production, in particular to an arrangement method of a coil conveying system in a multi-span copper plate and strip workshop with a centralized annealing furnace.

Background

The development trend of the nonferrous metal processing industry is to perform division of labor and further specialization and refinement, which is particularly reflected in the aspects of processing technology, equipment control, production line construction and the like of copper and copper alloy plate strips (hereinafter referred to as copper strips) as important structural materials and functional materials.

The construction of the copper plate strip processing production line is gradually changed from the previous large-scale, extensive, large and omnidirectional reasonable-scale, compact layout, refined production and other directions, and the construction is particularly reflected in project construction with the production scale of 1-3 ten thousand per a.

As typical processing equipment of a copper plate and strip production line, a bell jar type annealing furnace which simultaneously considers heat treatment processes such as homogenization annealing, intermediate stress relief annealing, recrystallization annealing, low-temperature finished product annealing and the like plays an increasingly important role in the processing process, the arrangement type and the workshop position of the bell jar type annealing furnace also directly influence the human flow, the logistics, the production rhythm, the production safety, the workshop span and length size, the quantity configuration of cranes and the like in a factory building, and the bell jar type annealing furnace is a pivotal link of a copper plate and strip processing technology and the production line.

At present, bell-type annealing furnaces which are intensively arranged on production lines of some copper plate and strip processing projects need to receive upstream horizontal continuous casting coil blanks and cold rough and medium rolling strip blanks, and downstream horizontal continuous casting coil blanks and cold rough and medium rolling strip blanks need to be produced in association with cold medium and fine rolling mill strip blanks, surface cleaning machine strip blanks and recoiler strip blanks, so that the layout difficulty of a workshop is increased, and particularly the transportation complexity of materials is improved. For a multi-span arranged copper plate and strip workshop, the over-span transportation of upstream blanks, intermediate in-process products and finished products is also considered, which cannot meet the production requirements under the arrangement condition of the conventional workshop at present.

After the bell-type annealing furnaces in the multi-span copper plate strip processing workshop are intensively arranged, the coil conveying system of the bell-type annealing furnaces has the following problems (part or all) according to the conventional arrangement method:

(1) the total length of the workshop is too large, the ineffective utilization area is increased, and the construction investment is increased.

(2) The number of the configured cranes (generally more than 5 cranes) needs to be increased in the span, the number of sets of equipment in the span is generally exceeded, the equipment investment of a production line is increased, and the effective operation and the utilization space of the cranes in a workshop are greatly reduced.

(3) The cross-inside cranes are configured according to the conventional number, and need to be transported for a long distance (generally at least more than 20-30 m), so that the normal production hoisting of the cross-inside equipment is seriously influenced.

(4) The electric flat car system for transporting the cross-span internal coil and the cross-span transport coil by the crane has interference of different degrees, such as production disadvantages of mutual avoidance, relay lifting, delayed loading and unloading of equipment, temporary storage of coil to be transported and the like.

(5) The cranes in the workshop need to catch up with each other, and the operation of one crane can require a plurality of cranes to move passively to avoid.

Through the analysis of the content, the material roll transportation system and the method which can effectively improve the concentrated arrangement of the bell-type annealing furnaces in the multi-span copper plate and strip processing workshop are designed, so that the number of inter-span internal transportation equipment between the workshops is effectively reduced, the length of the workshop is reduced, the construction investment is reduced, and a high-efficiency, low-cost and safe production mode is carried out, so that the problem to be solved urgently in the non-ferrous metal processing industry, particularly in the field of copper plate and strip production and construction is solved.
