Description

Technical Field

[0001] The utility model relates to the technical field of material containing devices, in particular to a material rack for tempering wear-resistant steel bars. Background Art

[0002] Wear-resistant steel rods are often used as loading grinding bodies for rod mills and are widely used in primary grinding in artificial stone sand, ore dressing plants, chemical plants and power departments. Wear-resistant steel rods use centrifugal force and friction to crush the materials to be ground, so their material strength and wear resistance are particularly important. At present, trolley-type tempering furnaces are often used to temper steel rods to change the organizational structure of the steel rod medium, making the metallographic structure of the grinding rods more dense and wear-resistant, and significantly improving the impact toughness. During the tempering process, the steel rods of the metal material are placed on the trolley, and then pushed into the furnace through the trolley. From the perspective of furnace loading, the wear-resistant steel rods are mostly laid on the upper surface of the trolley in a single layer, which cannot fully utilize the internal space of the furnace cavity, affecting the processing efficiency. At the same time, there is a lack of corresponding limiting mechanism between the steel rods, which is easy to shift, resulting in material stacking, affecting the tempering effect; and during the tempering process, the slag produced by the combustion of carbide particles lacks a corresponding collection mechanism, and falls into the furnace cavity of the tempering furnace, causing pollution to the furnace cavity. Utility Model Content

[0003] The utility model is aimed at the above problems and specifically designs a wear-resistant steel bar tempering material rack, which is equipped with a slag collecting mechanism to improve the tempering quality and efficiency of the tempering furnace.

[0004] To achieve the above-mentioned purpose, the utility model provides a material rack for tempering wear-resistant steel bars, comprising a slag box and a support layer, wherein the slag box is arranged on a trolley, the slag box is provided with a slag groove and a positioning groove, and the support layer is detachably connected to the slag box through the positioning groove; the support layer comprises a support column and a material receiving rack, the material receiving rack is a frame structure with a positioning groove, the positioning groove matches the support column, the material receiving rack has a plurality of support columns, and the support columns are detachably connected between the slag box and the material receiving rack and between adjacent material receiving racks; the wear-resistant steel bars are arranged on the material receiving rack.

[0005] By adopting the above technical scheme, the slag collecting box is used to collect the slag produced by the combustion of carbide particles, reducing the pollution of the slag to the trolley during the tempering process, and making it convenient for workers to clean up the slag; the support layer includes multiple receiving racks, which fully utilize the spatial structure of the tempering furnace cavity to process more wear-resistant steel bars at one time and improve the tempering efficiency. The receiving racks separate the wear-resistant steel bars of each layer, increase the structural restrictions on the steel bars, prevent displacement, and improve the tempering effect; the support columns and the slag collecting box and the receiving racks are all detachably connected, and the appropriate support layer can be assembled by oneself according to the tempering furnaces of different heights and different processing and use requirements, which has strong operability and reduces resource waste.

[0006] Furthermore, the slag collecting box covers the surface of the trolley.

[0007] By adopting the above technical solution, the slag collecting box completely separates the support layer from the trolley, preventing slag from falling and accumulating on the upper surface of the trolley, reducing pollution to the furnace cavity, and increasing the service life of the tempering furnace equipment.

[0008] Furthermore, the material receiving rack is provided with a limiting groove.

[0009] By adopting the above technical solution, the limit groove is used for structural restriction of the wear-resistant steel rods, separating the wear-resistant steel rods in the same layer to prevent accumulation and uneven heating, thereby improving the tempering effect of the product.

[0010] Furthermore, the limiting groove is an arc-shaped limiting groove.

[0011] By adopting the above technical solution, the arc limit groove fits the curvature of the wear-resistant steel rod more closely, increases the contact area between the groove bottom and the steel rod, reduces the deformation caused by stress concentration, and improves the product processing quality.

[0012] Furthermore, the material receiving frame is fixedly connected with reinforcing ribs.

[0013] By adopting the above technical solution, the reinforcing ribs are used to increase the strength of the joint surface of the receiving rack, reduce the degree of thermal deformation of the receiving rack, ensure the stability of the receiving rack in carrying the wear-resistant steel rods, and thus effectively improve the tempering quality of the product.

[0014] Furthermore, the material receiving rack is also fixedly connected with a support plate.

[0015] By adopting the above technical solution, the wear-resistant steel rod may be severely deformed or even broken during the tempering process. The support plate is used to separate the layers of wear-resistant steel rods, increase the deformation limit of the wear-resistant steel rods, reduce the impact on other wear-resistant steel rods, and ensure the quality of the finished product.

[0016] Furthermore, a lifting lug is fixedly connected to the peripheral side of the material receiving rack.

[0017] By adopting the above technical solution, the lifting lug is used for loading the sling. Before and after tempering, the material rack and the wear-resistant steel rod carried by the sling can be transferred with the help of the sling. The operation is easy, manpower and time are saved, and the tempering process is accelerated.

[0018] In summary, the utility model has the following advantages and beneficial technical effects:

[0019] 1. The utility model utilizes a slag collecting box to collect slag produced by the combustion of carbide particles, thereby reducing pollution to the trolley, increasing the service life of the tempering furnace, and saving workers' cleaning time; according to different usage requirements, the support layer of suitable height can be assembled by oneself, and the multi-layer receiving rack can be detachably stacked to improve the utilization efficiency of the tempering furnace cavity, so that more wear-resistant steel bars can be processed at one time, and the tempering efficiency is improved; in addition, the receiving rack separates the layers of wear-resistant steel bars, increases the structural restrictions on the steel bars, prevents displacement, and improves the tempering effect.

[0020] 2. The arc-shaped limit grooves on the material receiving rack are used to limit the structure of the wear-resistant steel bars on the same layer to prevent uneven heating caused by accumulation; the arc shape fits the shape of the wear-resistant steel bars better, and reduces the deformation caused by stress concentration by increasing the contact area; the reinforcing ribs are used to increase the strength of the joint surface of the material receiving rack, ensure the stability of the material receiving rack in carrying the wear-resistant steel bars, and improve the quality of product tempering processing.

[0021] 3. The support plate is used to separate the layers of wear-resistant steel bars, increase the deformation limit of the wear-resistant steel bars, reduce the impact on other wear-resistant steel bars, and ensure the quality of the finished product.

[0022] 4. The lifting lugs are used to load the slings, which can be used to easily transfer the material receiving rack and wear-resistant steel bars, saving manpower and time and speeding up the tempering process. BRIEF DESCRIPTION OF THE DRAWINGS
