Compared with the casting process, the forging process of 17GL7-1 scraper conveyer can make the hardness, strength and service life of the scraper more in line with the service requirements. But the forging process of 17GL7-1 scraper is difficult to be controlled in the actual production process. The following coal manufacturers double zhi machine will give you the introduction of 17GL7-1 scraper forging process of the three points. 1. Heat the scraping slab The main purpose of heating 17GL7-1 scraper blank is to increase its hardness, toughness and service life. When 17GL7-1 scraping slab is heated and tempered, the oxide layer on the surface of the slab is constantly knocked out to ensure the hardness and toughness of the product, and meanwhile, the smoothness and flatness of the surface of 17GL7-1 scraping slab is also ensured. In the process of shaping the billet, the temperature should be lowered to about 1100 degrees Celsius to achieve a good shaping effect and increase the plasticity of the scraper. 2. Control of quenching temperature After being heated and tempered, the 17GL7-1 scraper needs to be put into water to be quenched, so that the hardness and strength of the 17GL7-1 scraper are strong. Quenching temperature control is the key and difficult point in the forging process of scraper. Good temperature control can ensure the quality of the scraper and the surface flatness. If the temperature difference is too big, it will lead to the surface of the scraper crack. In quenching, the need to choose the appropriate quenching temperature according to different scraper material. When quenching, field tests should be carried out to control the hardness value. After the scraping plate quenching, but also for the scraping plate residual temperature treatment. 3. Impact energy of a forging hammer China's scraper conveyor production started late, the initial use of the type of die forging hammer is relatively small, the hardness and quality of the die forging hammer is greatly limited, the impact energy of the die forging hammer is far unable to reach the production of the strike energy required by the scraper. The hydraulic force is then used to increase the impact energy of the hammer. The impact quality of the die forging hammer meets the requirements of the scraper manufacturing, the production of 17GL7-1 scraper quality, hardness can be qualified. The above is the key and difficult points of 17GL7-1 scraper forging process. Henan Shuangzhi Machinery Equipment Co., Ltd. based on the coal machine industry for many years, mature technology, diversified equipment, the production of coal machine parts forging strength, high hardness, strong toughness, well received by customers, if you have coal machine parts procurement needs, you are welcome to inquire, to visit the factory.
A conveyor belt is a looped belt that is driven by and wrapped around one or more pulleys. It is powered by an electric motor and supported by a metal plate bed or rollers upon which the conveyor belt rests. The pulley that powers a conveyor belt is referred to as the drive pulley and has an unpowered idler pulley.
Our roller coatings provide a stable grip, are long-lasting, and resistant to damage from high temperatures, abrasion, oil, and chemicals. The majority of coverings are available with a self-adhesive backing that is high-heat resistant, guaranteeing a high level of adhesion to the roller. In addition, we provide non-adhesive roller covering tape with a selection of very fine specialty contact adhesives. Depending on the purpose, a variety of materials are used to create our roller covers.

Waste Specification: European Classification: E46 EWC Code: 19.01.02 Basel Code: B10 10 The material is loose steel scrap processed through an incinerating plant for domestic waste followed by magnetic separation, fragmentized into pieces and consisting partly of tin coated steel cans. At a visual inspection, the material is fragmentized, with iron and steel parts, resulting partly cut or in shredded form. The stock appears heterogeneous and contains all kind of cut or dismantled steel parts such as sheets, bars, frames, wires, bolts and other iron/steel household residues. The incinerated scrap is eventually oxidized, due to the thermal and cooling treatments, that the material has been submitted to. The burnt scrap also contains minor slag parts, ash and iron oxide, due to the recovery process. Such components are inherent and adhere to the scrap surface. The total impurities, can be sorted, but not fully removed. The consignment does not contain any type of arms, ammunition, mines, shells, cartridges, radioactive contaminated, or any other explosive material in any form either used or otherwise. The collected stock, is stored in open air, on cemented flooring. Due to the scrap dimensions and the material conditions, this particular scrap, should be carefully evaluated first, by the end users, to confirm its adequate recovery ratio and its suitability to be re-melted in the electric arc furnace. Please feel free to contact us for further details
The Incinerated scrap or E46, is the by-product derived from the reprocessing of incinerated domestic waste. After the combustion process, the furnace output (IBA Incinerator bottom ash) is firstly washed, magnetically separated and screened to separate any no ferrous material. At a visual inspection, the material is fragmentized, with iron and steel parts, resulting partly cut or in shredded form. The stock appears heterogeneous and contains all kind of cut or dismantled steel parts such as sheets, bars, frames, wires, bolts and other iron/steel household residues. The incinerated scrap is eventually oxidized, due to the thermal and cooling treatments, that the material has been submitted to. The burnt scrap also contains minor slag parts, ash and iron oxide, due to the recovery process. Such components are inherent and adhere to the scrap surface. The total impurities, can be sorted, but not fully removed. The consignment does not contain any type of arms, ammunition, mines, shells, cartridges, radioactive contaminated, or any other explosive material in any form either used or otherwise. The collected stock, is stored in open air, on cemented flooring. It can be loaded loose in 20â?? heavy duty container. Please feel free to contact us for further details.
The gear track of the scraper is installed on the gear track seat of the middle slot, which is the track supported and guided by the shearer. It is an important support point for the stability of normal coal mining for the shearer to realize the haulage of the shearer relying on the tooth and rail pin tooth of the scraper. Therefore, scraper conveyor parts manufacturers remind you to use a more durable scraper conveyor gear track. At present, the teeth and rails of the plate scraper in the market mostly adopt the structural forms such as integral die forging, integral casting, split welding and forging welding. Fission welding type rack and forge welding type rack is a compound structure, by putting the two track plate and pin gear processing compound into an organic whole, due to welding and machining accuracy cannot be guaranteed, so prone to open the phenomenon such as welding, fracture, wear, these two kinds of structure of the rack can't meet the need of the high-power coal winning machine supporting the fully mechanized coal face. Although the whole cast gear track avoids the problem of gear track cracking to some extent, the casting strength obviously fails to meet the use requirements, which affects the coal mining efficiency. The integral die forging gear track is strengthened by heat treatment of alloy structural steel. It adopts die forging technology and completes the manufacturing process by a series of procedures such as forging, forming, trimming and punching. Therefore, the overall strength of the tooth and rail of the scraper is higher than the above three technologies, the pin tooth position and tooth shape processing accuracy is more guaranteed, can make the shearer and the tooth and rail better mesh, the impact force in the use process is also smaller, for the large power shearer, conveyor supporting use to provide a guarantee. The integral die forged gear rail can meet the required performance requirements and is more durable. After reading, you choose and buy which scraper gear rail heart roughly spectrum!
