Description

Technical Field

[0001] The utility model relates to the technical field of high-carbon ferrochrome smelting, in particular to a reducing agent feeding structure for high-carbon ferrochrome smelting. Background Art

[0002] High carbon ferrochrome is an alloy, usually containing 4-6% carbon and 50-70% chromium. It is an important iron alloy used to produce stainless steel, alloy steel and other materials. In the smelting process of high carbon ferrochrome, metallurgical coke and blue coke are used as reducing agents. However, during the process of adding the reducing agent, the reducing agent cannot be in good contact with the raw materials, which affects the quality of the produced high carbon ferrochrome. Therefore, in consideration of both ensuring product quality and controlling production costs, a device that can control the feeding speed and uniform feeding is required, and a composite reducing agent with good particle size, high strength and good air permeability in the furnace during the production process is selected for smelting.

[0019] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0020] In order to further understand the content of the utility model, the utility model is described in detail in conjunction with the accompanying drawings.

[0021] Combination Figure 1 A reducing agent feeding structure for high carbon ferrochrome smelting comprises an electric furnace body 1, and a reducing agent feeding mechanism 3 for feeding the reducing agent is arranged on one side of the electric furnace body 1.

[0022] The utility model is further described below in conjunction with embodiments.

[0023] See also Figure 2-Figure 3 The reducing agent feeding mechanism 3 includes a storage barrel 31 fixedly connected to the outside of the electric furnace body 1, a hopper 32 is fixedly connected to the upper surface of the storage barrel 31, and a motor chamber 33 is fixedly connected to one side of the hopper 32. A discharge assembly 34 for discharging the reducing agent into the electric furnace body 1 in multiple times is arranged inside the storage barrel 31. Through the arrangement of the storage barrel 31, the hopper 32 and the motor chamber 33, the reducing agent can be poured from the hopper 32 before the start of smelting. The storage barrel 31 is used to temporarily store the fallen reducing agent, and the reducing agent in the storage barrel 31 and the hopper 32 is subsequently added to the inside of the electric furnace body 1 through the discharge assembly 34.

[0024] The material discharge component 34 includes a material discharge motor 341 fixedly connected to the inner wall of the motor chamber 33, the output end of the material discharge motor 341 is fixedly connected to a rotating shaft 342, a push plate 343 is fixedly connected to the outer side of the material discharge motor 341, and a baffle 346 is fixedly connected to one side of the push plate 343. A valve 347 and a material discharge trough 348 are fixedly connected to the bottom surface of the storage barrel 31. The valve 347 and the material discharge trough 348 are symmetrically arranged, and the material discharge motor 341 drives the rotating shaft 342 to rotate, thereby driving the push plate 343 and the baffle 346 to rotate. During the rotation, the push plate 343 pushes the reducing agent that falls on the upper surface of the valve 347 and drops it into the interior of the electric furnace body 1 through the material discharge trough 348. The material discharge trough 348 has the effect of screening the particle size. During the rotation, the baffle 346 can temporarily block the reducing agent from falling from the top to prevent the material discharge speed from being too fast and difficult to control. Finally, the unqualified reducing agent with larger particles falls into other collecting components through the valve 347.

[0025] A bottom groove 344 is provided on the bottom surface of the push plate 343, and a brush 345 is fixedly connected to the inner wall of the bottom groove 344. The brush 345 fits the upper surface of the discharge groove 348. The arrangement of the bottom groove 344 and the discharge groove 348 can assist in pushing the reducing agent to move while achieving a certain cleaning effect.

[0026] A collecting cylinder 36 is fixedly connected to the bottom surface of the storage cylinder 31, and the opening direction of the collecting cylinder 36 corresponds to the valve 347. A fan 35 is fixedly connected to the inner wall of the collecting cylinder 36, and the blowing direction of the fan 35 corresponds to the bottom of the material discharge chute 348. A material removal door B37 is hinged on one side of the collecting cylinder 36. Through the arrangement of the collecting cylinder 36 and the fan 35, the purpose of collecting the reducing agent with unqualified particle size is achieved. At the same time, the fan 35 can drive the air flow to promote the smelting reaction inside the electric furnace body 1, and can also blow away the reducing agent falling from the material discharge chute 348 to achieve the effect of uniform material discharge. The material removal door B37 is used to remove the unqualified reducing agent later.

[0027] An electric heating plate 4 for heating the reaction is arranged inside the electric furnace body 1. The arrangement of the electric heating plate 4 provides heating conditions for high carbon ferrochrome smelting.

[0028] A material feed cover 12 is hingedly connected to the upper surface of the electric furnace body 1, and a material taking door A11 is hingedly connected to the outer side of the electric furnace body 1. The material taking door A11 and the material feed cover 12 are arranged to facilitate the placement and removal of raw materials.

[0029] The bottom surface of the electric furnace body 1 is fixedly connected with a base 2, and the setting of the base 2 ensures the working stability of the smelting process.

[0030] Specifically, during the reducing agent feeding process, the reducing agent is poured into the feed hopper 32, and the feeding motor 341 is turned on at the same time. The feeding motor 341 drives the rotating shaft 342 to rotate, and then drives the pushing plate 343 and the baffle 346 to rotate. During the rotation process, the baffle 346 temporarily blocks the feeding. At the same time, the pushing plate 343 pushes out the falling reducing agent, transfers it from the upper surface of the valve 347 to the feeding trough 348, and falls from the feeding trough 348 into the interior of the electric furnace body 1. The feeding trough 348 plays a role in screening the particle size. The feeding speed is controlled and slowed down by the blocking and pushing of the baffle 346 and the pushing plate 343. The falling reducing agent is blown away by the fan 35, which has the effect of uniform feeding. Unqualified reducing agent with larger particles is discharged into the collecting cylinder 36 through the valve 347 for collection, thereby achieving the purpose of controlling the feeding speed and uniform feeding.
