Supply Sgz960 Scraper Conveyor Flight Bar For Coal Mine

The flight bar is the bearing part for transporting coal, which is fixed on the chain by bolts to form the scraper chain as the traction member. When the drive part of the nose starts, the sprocket shaft set rotates, so that the scraper chain circulates and drives the coal to move along the chute until unloading at the head. There are 45#, 40Cr, 27SiMn and so on.

45# material is usually called 45 steel, is a kind of high quality carbon structure steel, is one of the materials used in the market scraping plate quality, its hardness is not high free cutting processing, in the mold application is often used as a template material. And as some of the workpiece, usually must be used for heat treatment, improve their hardness, wear resistance and service life.

40Cr material is one of the preferred steels in mechanical manufacturing industry. It is also a good choice for flight bar quality. It is a medium carbon tempered steel and cold heading die steel. It has good comprehensive mechanical properties, good low temperature impact toughness and low notch sensitivity after quenching and tempering. 40Cr material has good hardenability and can obtain good toughness, plasticity and wear resistance after proper heat treatment.

Selection and application of scraper material

27SiMn material has high hardenability, good machinability, cold deformation plasticity and medium weldability, and is also one of the choices of scraping plate quality. High strength and wear resistance during heat treatment, especially high toughness during water quenching; However, the steel is sensitive to white point and has brittleness tendency of tempering and sensitivity of overheating during heat treatment. This kind of steel is mainly used in the quenched and tempered state for the manufacture of hot stamping parts requiring high toughness and wear resistance. It can also be used in normalizing or hot rolling supply.

Selection and application of scraper material

Through the above comparison, we also have a partial understanding of the scraper material. From the perspective of material performance, the 40Cr material is a better choice, which can meet the requirements of the scraper in the coal mine working environment. Henan Shuangzhi Machinery from the beginning of the establishment of the factory focused on the production and processing of the parts of the scraper, and the scraper is one of its main products, we have been very careful about the selection of the plate quality, because no matter how good the process also needs to have a good material foundation support, which is also the guarantee of product quality, but also to promote the development of the enterprise.
