Embodiment 1
[0072] The maximum bearing weight of the existing furnace body in a workshop is 3t, which is suitable for casting small and medium-sized castings. Now it has received a research and development task for a large cabin section. After calculation, the maximum pressure on the furnace body will be as high as 4.5t when pouring this casting. There is a furnace body that cannot be poured.
[0073] The specific parameters of the bracket are determined according to the size of the casting furnace body and crucible in the workshop as follows:
[0074] The distance between the two load-bearing beams 101 is L1=1200mm;
[0075] The overall height of the load-bearing device H1=500mm;
[0076] The distance between the two support beams 102 is L2=1600mm;
[0077] The profiles that meet the conditions are determined by comparing the above parameters with the profile list. Since the I-beam, H-beam and square steel do not satisfy H<100mm, the profile 8# channel steel is selected as the producti...
