Cast iron flat working surface flatness test is a measure of the quality of the main inspection plate accuracy specifications. According to the national standard GB / T 22095-2008 cast iron inspection plate flatness tolerance allowable value, determine the exact level of inspection plate gray cast iron plate, 0,1,2,3 level. I produced after two manual inspection plate is tempered, VSR, fine planing machine, artificial sperm shovel and national quality inspection departments strict inspection made products strictly through all aspects of the cast iron plate measuring, testing every aspect The small differences, and in order to avoid the inspection plate breaks under heavy load, we also take in favor of free shrinkage of the structure flat iron plate manufacturers, easy to produce or enhance the structural strength of the crack, the improvement is more comprehensive than a few aspects to enhance our inspection High efficiency flat iron plate, in a competitive market, but also have a more powerful backing cast iron inspection plate appearance:! made T-shaped or I-shaped, face a rectangular, square or round, should be marked with the manufacturer's name (or factory standard), the level of accuracy, specifications and numbers; Face should not have cracks, rust, scratches, bumps, dents, impurities and other defects in flat affect test accuracy. Maintenance inspection plate: Use process should avoid excessive local wear, scratches and bumps phenomenon, to avoid affecting the accuracy and face life; inspection plate of life under normal conditions should be permanent in nature, the use of should be cleaned, improve anti-rust work to prevent deformation due to corrosion Face.
