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...

Abstract

The invention discloses a method for casting a machine tool body from steel-making tailings. The method comprises the following steps: crushing steel-making tailings, separating the steel-making tailings, crushing iron sand, performing ball-milling, preparing a mixed solution of an epoxy resin and a curing agent, and finally performing steps of stirring, vacuum suction injection, heating curing, demolding, mechanical processing and the like, thereby obtaining the machine tool body. As the machine tool body is cast from the steel-making tailings, the mechanical properties of a machine tool arecomprehensively and remarkably improved, the stability of the machine tool is improved, the thermal expansion coefficient is reduced, the precision of the processing process of the machine tool is improved, the product pass percent is increased, and the processing cost is indirectly reduced. As the machine tool body is cast from the steel-making tailings, resource recycling is achieved, wastes areturned into wealth, the environment pollution is reduced, and the method is a significance innovation of machine tool body casting materials and has great significances.

Description

technical field [0001] The invention belongs to the casting process of machine bed, and in particular relates to a method for casting machine bed by using steelmaking tailing slag. Background technique [0002] A machine tool refers to a machine that manufactures a machine, also known as a machine tool or a tool machine, and is customarily referred to as a machine tool. Generally divided into metal cutting machine tools, forging machine tools and woodworking machine tools. There are many ways to process mechanical parts in modern machinery manufacturing: in addition to cutting, there are also casting, forging, welding, stamping, extrusion, etc. The final machining is done by cutting on the machine tool. Machine tools play an important role in the modernization of the national economy. Because the machine tool has strict requirements on the stability of the machine bed during the working process. [0003] At present, most of the machine bed materials on the market are mai...
