Introduction:Botou Guangyuan Casting Machinery Co., Ltd. is located in the famous town of casting, "Botou". Located north of Beijing and Tianjin, and east of Bohai Sea, the Beijing Shanghai Railway, Shihuang, and Beijing Shanghai Expressway run through the city, providing convenient transportation and a superior geographical location. Our company is a professional enterprise engaged in casting, mechanical processing machine tool equipment matching, and machining. We have strong technological advantages and can provide customers with comprehensive after-sales service. The products mainly include cast iron flat plates, cast iron platforms, cast iron square boxes, cast iron bending plates, machine tool pad iron milling machines, planers, automotive mold machine tools and other casting measuring tools and machine tool products.

Cast iron platform, also known as cast iron flat plate, can be used as a measurement benchmark for checking the flatness, parallelism, straightness and other geometric tolerances of mechanical parts. It can also be used for marking and measuring precision parts, experiments, riveting and welding, foundations, workbenches. The working surface of cast iron platform (flat plate) adopts scraping and grinding technology, and the working surface can be designed with circular holes, rectangular holes, square holes, etcTType grooveUType grooveVType groove.

Platform material: Made of high-strength cast ironHT200-250The hardness of the working surface isHB160-210.After two treatments (manual annealing)（600·----700·And natural time efficiency2----3The product has stable accuracy and good wear resistance.

Platform structure: made into reinforced plate and box type, with rectangular, square or circular working surfaces. The working surface adopts scraping technology, and it can be machined on the working surfacevFormTFormUGroove and circular hole, etc.

The purpose of the cast iron platform (flat plate) is to be used as a reference plane for various inspection work and precision measurement. It is used as a benchmark for machine tool mechanical measurement, to check the dimensional accuracy or form and position deviation of parts, and to make precise markings. It is also an essential basic tool in mechanical manufacturing.

Cast iron platform (flat plate) accuracy: Cast iron platform (flat plate) flat plate according to national standardsGB7947-1999Standard manufacturing. According to the national standard metrological verification regulations, they are as follows:0，1，2,3There are four levels.

Metal Heat Treatment in Cast Iron Platform Process:

Heat treatment of cast iron platform metal is one of the important processes in mechanical manufacturing. Compared with other processing techniques, heat treatment generally does not change the shape and overall chemical composition of the workpiece, but rather imparts or improves the performance of the workpiece by changing the microstructure inside the workpiece or changing the surface chemical composition of the workpiece. Its characteristic is to improve the intrinsic quality of the workpiece.

In order to provide metal workpieces with the required mechanical, physical, and chemical properties, in addition to the rational selection of materials and various forming processes, heat treatment processes are often essential. The most widely used material in the steel machinery industry, steel has a complex microstructure that can be controlled through heat treatment, so heat treatment of steel is the main content of metal heat treatment. In addition, alloys such as aluminum, copper, magnesium, titanium, and others can also change their mechanical, physical, and chemical properties through heat treatment, resulting in different performance characteristics.

Integrated heat treatment is a metal heat treatment process that heats cast iron workpieces and then cools them at an appropriate rate to change their overall mechanical properties. The overall heat treatment of steel generally includes four basic processes: annealing, normalizing, quenching, and tempering.
