Embodiment 1
[0024] A machine tool bed cast by steelmaking tailings is mainly made of the following raw materials in parts by weight:
[0025] 65 parts of steelmaking tailings, 5 parts of iron sand powder, 10 parts of silica powder, 5 parts of quartz sand, 5 parts of quartz powder; 7 parts of epoxy resin, 1.75 parts of curing agent, 1 part of carbon fiber, 1 part of basalt fiber, and 1 part of bismuth .
[0026] The steelmaking tailings are crushed and pulverized into irregular granules with a size of 3-15 mm. The steelmaking tailings contain iron oxide, calcium oxide, silicon dioxide, magnesium oxide, manganese oxide, ferroalloy slag, and scrap steel slag. The steelmaking tailings are alkaline, with an alkalinity of 2.5-3.5. The steelmaking tailings have a viscosity of 0.02-0.07 Pa·s. The carbon fiber and basalt fiber are short fibers with a length of 35-150 mm. The curing agent is a modified acid anhydride curing agent.
[0027] The performance of the machine tool bed cast according...
Embodiment 2
[0039] This embodiment is basically the same as Embodiment 1, the difference is that:
[0040] 75 parts of steelmaking tailings, 10 parts of iron sand powder, 5 parts of silica powder, 10 parts of quartz sand, 10 parts of quartz powder; 10 parts of epoxy resin, 2.5 parts of curing agent, 1 part of carbon fiber, 1 part of basalt fiber, 1 part of antimony share.
[0041] The performance of the machine tool bed cast according to the present embodiment is tested as follows:
