Embodiment 1
[0027] A method for casting a bed of a machine tool using steelmaking tailings, comprising the following steps:
[0028] 1. Put the recovered steelmaking tailings into the crushing machine for crushing, and then crush them through the crushing equipment to obtain irregular tailings particles with a size of 3-15mm for use;
[0029] 2. The recovered iron sand is crushed and ball milled to make iron sand powder for later use;
[0030] Three, get 7 parts of epoxy resin by weight and add epoxy resin diluent and mix into solution, add 2.1 parts by weight of anhydride curing agent, add 1 part of bismuth and mix and stir to make the mixed solution for subsequent use;
[0031] 4. Take 65 parts by weight of steelmaking tailings, 5 parts of iron sand powder, 10 parts of silica powder, 5 parts of quartz sand, and 5 parts of quartz powder into the mixer, mix and stir evenly, and then add the mixed solution prepared in step 3 , stir evenly again, finally add 1 part of carbon fiber and 1 pa...
Embodiment 2
[0047] This embodiment is basically the same as Embodiment 1, the difference is:
[0048] 3. Get 10 parts of epoxy resin by weight and add epoxy resin diluent to mix into a solution, add 3 parts of anhydride curing agent by weight, add 1 part of antimony and mix and stir to make a mixed solution for subsequent use;
[0049] Four, get 75 parts by weight of steelmaking tailings, 10 parts of iron sand powder, 5 parts of silica powder, 10 parts of quartz sand, 10 parts of quartz powder are added in the mixer, mix and stir evenly, then add the mixed solution that step 3 makes, Stir again evenly, and finally add 1 part of carbon fiber and 1 part of basalt fiber, then seal and vacuum the mixer, and stir again for 5-10 minutes at a vacuum degree below 0.001Mpa to obtain a mixed material;
[0050] The remaining steps are consistent with Embodiment 1.
[0051] In this embodiment, the multi-batch machine tool beds casted according to the above method are tested, and the results are as f...
