Cast to track Description: The main purpose: based on a fixed-point devices to design, cast beams spliced ??into the platform, mainly used for assembling, testing, welding and inspection of large equipment. To track uses: based on a fixed-point devices to design, cast beams spliced ??into the platform, mainly used for assembling, testing, welding and inspection of large equipment. To track advantages: so do not make a large platform, which saves material costs, but also takes up very little space and can be described as the high cost. To track material: high-strength cast iron HT200-300, face hardness of HB170-240, after two manual processing (annealing 600 degrees -700 degrees artificial and natural aging) so that the accuracy of product stability, good wear resistance. Phone: 1, fixation iron rail to rail 15,194,701,962 to lay the technical requirements on both sides of the inside of the track, as required spacing (approximately 500-700mm) with M8 expansion of iron nails or nail securely. The bottom surface of the ground must be closely track focus, not a virtual cross the gap to prevent the bending loads to rail tracks. 2, the installation to track: Use bar deck, as the level of co-meter. First leveling a ground track, then its basis, then goes conduct initial adjustment. Then cement grout, grout upon solidification, fine-tune test. 3, buried to a depth of cast iron rail decorative layer and the ground should be flat or slightly higher than 3-5mm. 4, to track installed, should any of 1m length, horizontal deviation of not more than 1mm, the whole grow at 2mm, which tracks between the level of the corresponding point deviation is less than 1mm, the parallelism between the two tracks each deviation is less than 2mm. To track the specification: The specification can be agreed upon production and processing according to the demand side, drawing production or both. Website: http:www.btmwlj.com/
