Embodiment 1

[0041] A high-strength wear-resistant swirl replaceable blast furnace cooling column in this embodiment includes a water inlet pipe 1, a water outlet casing 2 and a wear-resistant copper sleeve 3. The cooling end of the wear-resistant copper sleeve 3 is inserted into the cooling wall of the blast furnace, and the inner wall There is a spiral groove 31 that rotates outward; the water outlet casing 2 is in the shape of a U-shaped sleeve, and the right end has a concentric hole 23, and the left end is fixedly connected with the tail end of the wear-resistant copper sleeve 3, and the side wall is provided with a water outlet to connect the outlet Water pipe 21; the insertion end of the water inlet pipe 1 is inserted into the cavity of the wear-resistant copper sleeve 3 through the concentric hole 23, and is in close contact with the wear-resistant copper sleeve 3, forming a strong internal support for the wear-resistant copper sleeve 3, the outer wall and The spiral groove 31 forms...

Embodiment 2

[0043] A high-strength wear-resistant swirling flow replaceable blast furnace cooling column in this embodiment, the specific structure is basically the same as that of embodiment 1, the improvement is that: the inner diameter of the water inlet pipe 1 is 32mm, and the outer diameter is 42mm; the outer diameter of the water outlet casing 2 is 100mm , the inner diameter is 80mm; the wear-resistant red copper sleeve 3 has an outer diameter of 100mm and an inner diameter of 60mm. The cross-section is square, the groove depth is 8mm, the width is 20mm, and the groove distance is 10mm. Compared with other shapes, the cooling area of ​​the cooling water is increased, and the cooling strength is also increased; the insertion end of the water inlet pipe 1 and the wear-resistant copper sleeve 3 A water flow transition chamber 33 is left between the ends of the sleeve chambers to effectively transition the water flow and play a role in stabilizing the water flow so that the water flow is...

Embodiment 3

[0045] A high-strength wear-resistant swirl replaceable blast furnace cooling column in this embodiment, the specific structure is the same as that of embodiment 2, the improvement is that the right end face of the wear-resistant protective cover 4 is sealed by a wear-resistant stuffy cover 5, and the material is also 1Gr18Ni9Ti type Stainless steel to protect the end of the wear-resistant copper sleeve; the outer end surface of the wear-resistant cover 5 is provided with a slag hanging device 51, which intercepts the slag and prevents the slag from directly abrading the wear-resistant protective cover, thereby strengthening the wear-resistant protective cover. Grinding copper sleeve for protection. The slag-hanging device 51 is an annular groove on the outer end face of the wear-resistant stuffy cover 5. The groove body formed by the annular groove has even slag hanging, and multiple channels can be arranged to form a uniform slag-hanging slag surface, so that the end face of ...

Abstract

The invention discloses a high-strength wear-resistant spiral-flow replaceable blast furnace cooling column and application thereof, which belong to the technical field of blast furnace cooling equipment. The high-strength wear-resistant spiral-flow replaceable blast furnace cooling column comprises a water inlet pipe, a water outlet sleeve pipe and a wear-resistant red copper sleeve. The cooling end of the wear-resistant red copper sleeve is inserted into a blast furnace cooling wall; outward-turning spiral grooves are arranged on an inner wall; the water outlet sleeve pipe is in a U-shaped sleeve shape; a concentric hole is formed in the right end of the water outlet sleeve pipe; the left end of the water outlet sleeve pipe is fixedly connected with the tail end of the wear-resistant red copper sleeve; a water outlet is formed in a side wall of the water outlet sleeve pipe and is connected with a water outlet pipe; the inserting end of the water inlet pipe penetrates through the concentric hole so as to insert into a sleeve cavity of the wear-resistant red copper sleeve, so that a powerful internal support is formed for the wear-resistant red copper sleeve; the outer wall and the spiral grooves form a circulating water channel; the tail end of the water inlet pipe exposes outside the concentric hole so as to be connected with a water source; cooling water can pass through the water outlet pipe and directly flows to the end of the sleeve cavity of the wear-resistant red copper sleeve, and then passes through the spiral grooves so as to form a circulating cooling water flow, and the outward-turning spiral grooves lead the water flow passing through the water outlet pipe of the water outlet sleeve pipe out of the pipe, so that the circulating cooling of the cooling water is completed; and the water inlet pipe and the red copper sleeve are matched mutually to achieve a synergistic effect.

Description

technical field [0001] The invention belongs to the technical field of blast furnace cooling equipment, and in particular relates to a high-strength wear-resistant swirling flow replaceable blast furnace cooling column and its application. Background technique [0002] Blast furnace hearth, furnace waist, furnace bosh and furnace cooling system are important equipment for blast furnace production. Blast furnace cooling stave is an important water-cooled part of blast furnace lining, which is installed on the furnace body, furnace waist, furnace belly, furnace hearth and other parts of blast furnace , not only withstand high temperature, but also bear the wear of the charge, the erosion of slag and the erosion of the gas flow, and must have good thermal strength, thermal shock resistance, rapid cooling and heat resistance and other comprehensive properties. The stave can effectively prevent the furnace shell from being heated and burned red. After the blast furnace lining bri...
