Problems solved by technology

Compared with the existing technology, this circulation pipe has been strengthened in structure, and the thermal expansion force of the interphase ring brick is greater than the buoyancy of molten steel, which solves the floating phenomenon of the circulation pipe. However, due to the limitation of its outer wall being square, it cannot Widely used in the current RH refining furnace
In addition, its processing and assembly process is relatively complicated.

Embodiment

[0028] Embodiment: a kind of RH furnace circulation tube, as Figure 8 As shown, the circulation pipe 12 is cylindrical in shape as a whole, and it is surrounded by a plurality of unit wedge-shaped bricks 11 in an alternating sequence of upright and upside down; Figure 9 As shown, the described unit wedge brick 11 is formed by stacking a long wedge brick 13 and a short wedge brick 14, and the brick shape of the long wedge brick 13 is as follows Figure 10 , Figure 11 As shown, the brick diagram of the short wedge brick 14 is as follows Figure 12 , Figure 13 As shown, a bayonet 15 is provided on the long wedge-shaped brick 13, the lengths of the long wedge-shaped brick 13 and the short wedge-shaped brick 14 are pre-calculated, and the bayonet 15 is exactly half the length of the unit wedge-shaped brick 11, that is, the center position place.

[0029] Thus, the adjacent unit wedge bricks 11 are placed upright and upside down alternately, and the joints 16 of the long wed...

Abstract

The invention discloses an RH furnace circulating pipe and a building method thereof. The cylindrical circulating pipe is built by alternately arranging a plurality of unit arch bricks obversely and inversely; each unit arch brick is piled by a long arch brick and a short arch brick; and a bayonet is arranged on the long arch brick, and is exactly positioned in the center of each unit arch brick. The RH furnace circulating pipe is improved on the traditional RH furnace circulating pipe, is designed according to the original style on integral appearance and size, replaces the conventional equilong flat building mode by adopting obversely and inversely building unequal arch brick combinations alternately, so that the paving seams among long arch bricks and short arch bricks are staggered, hot expansive force among alternate arch bricks is enhanced, and the problem of partial or whole flotation of the circulating pipe can be effectively solved.

Description

technical field [0001] The invention relates to a RH furnace, in particular to an improved and optimized RH furnace circulation pipe and a masonry method. Background technique [0002] Such as figure 1 Shown is the overall rendering of the traditional RH furnace circulation tube, which includes the lower cylindrical tube 1 and the upper conical tube 2, the cylindrical tube 1 is made of 1# wedge-shaped brick 3, and the 1# wedge-shaped brick 3 Renko such as figure 2 , image 3 As shown, the longitudinal sectional view of the cylindrical pipe 1 is as Figure 4 Shown; Conical tube 2 is assembled by 2# wedge-shaped brick 4, as Figure 5 , Figure 6 Shown is the brick diagram of 2# wedge brick 4, such as Figure 6 , Figure 7 As shown, the outer surface of 2# wedge-shaped brick 4 is a slope, and the lower half of the outer surface of 2# wedge-shaped brick 4 is provided with bayonet socket 5. [0003] The traditional RH furnace circulation tube adopts equal length and flat...
