An article to quickly understand what a ground channel iron is!
The quality of ground channel iron is important for every customer who uses it. The grade of ground channel iron is divided into Grade 0, Grade 1, Grade 2, etc. The grade requirements for ground channel iron are relatively high, making it suitable for use. Precautions when cleaning ground channel iron: resin sand molds have good rigidity, and the high strength of the sand mold during the initial pouring stage allows for the utilization of graphite expansion during the solidification process, effectively eliminating issues like shrinkage cavities and porosity, enabling the casting of ductile iron with fewer or no risers. In actual casting production, foam patterns are used with furan resin self-hardening sand for molding.
In practical use, ground channel iron can be categorized in detail. The raw materials used for ground channel iron are sourced from iron plates, which undergo aging treatment. Their structure is uniform, with minimal linear expansion, and internal stresses are completely eliminated, preventing deformation and ensuring high precision. It has high hardness, good rigidity, strong wear resistance, resistance to acid and alkali corrosion, no rusting, no need for oil coating, minimal dust adhesion, easy maintenance, and simple upkeep. It does not scratch during use, is unaffected by constant temperature conditions, and maintains measurement accuracy even at room temperature. It is non-magnetic, moves smoothly during measurement without sticking, is unaffected by moisture, and has various advantages such as stable flatness. Therefore, the ground channel iron in the marble platform is designed for use as a reference plane in production workshops or metrology departments for precision measurements.

What causes ground channel iron to deform? The deformation of ground channel iron may occur due to inadequate stress-relief annealing or aging after sand casting. It could also be caused by uneven support during use, leading to uneven force distribution at the four corners and resulting in deformation. The solution is to reapply aging treatment to the ground channel iron, striving for a rational structure and minimizing casting stress. Sometimes, counter-deformation measures are adopted during pattern manufacturing to control and adjust. Residual casting stresses are commonly relieved through natural or artificial aging methods. To eliminate internal stresses in ground channel iron, reprocess the deformed iron plate to restore its original accuracy. During use, ensure that the four corners of the iron plate are evenly supported to prevent deformation.
Although inspection ground channel irons are reference planes, their processing methods, flatness accuracy, and functional roles differ. Iron plates serve as reference surfaces when inspecting workpiece straightness using the coloring method or as auxiliary tools for various measurements. Iron plates are suitable for various inspection tasks, serving as reference planes for precision measurements, inspection benchmarks for machine tools, checking dimensional accuracy or form deviations, and precise marking. Ground channel iron is an indispensable basic tool in mechanical manufacturing. For example, it is used as a reference plane for precision measurements, inspection and measurement of various machine tools, checking dimensional accuracy and positional deviations, and performing precise markings. Ground channel iron is an essential product in over 20 industries, including mechanical manufacturing and electronic production.
During use, avoid excessive collisions between workpieces and the working surface of the single-surround ground channel iron to prevent damage. The weight of the workpiece should not exceed the rated load of the single-surround ground channel iron, as this could reduce work quality and potentially damage or deform the ground channel iron, rendering it unusable. Ground channel iron components should slide smoothly during measurement without sticking. General scratches on the working surface do not affect measurement accuracy.
