Short for [reinforcing bar," rebar is refers to metal – usually steel – that`s used to help increase the tensile strength of concrete for a variety of needs, including many of the most common construction types you see every day.
Concrete is known to be weak in the areas we just mentioned, at least compared to steel and other metal types. If this reinforcement was not used, these structures would at-risk of falling apart.
Rebar usually will be built so the metal component is not visible within the structure. Rather, it will be buried within the concrete. It`s usually made with ribs rather than smoothly, allowing it to avoid slippage within its structure.
How Rebar is Made
As we noted above, the most common material for rebar use is steel, which is used because of its excellent tensile properties. It`s often made from forms of recycled steel, which will be melted down using an electric arc furnace, cooled using billets, and then stored until it`s needed.
From here, billets can be reheated to an elevated temperature and fed through extrusion tools, then necked down until its proper size is reached. Finally, it will be tooled to create the proper ribbing, which we noted above is in place to prevent slippage within concrete. Then it will be sheared to the proper length, and it`s ready to go.

The domestically-manufactured numerical control system is being accepted by people. We are pleased to see that the number of domestically-manufactured numerical control systems for the main engine plant has increased a lot compared to the previous exhibitions. The domestically-manufactured numerical control systems represented by Huazhong CNC and Guangzhou CNC are maturing, and They are active in various technical exchanges and lectures during the show. In the extensive contact with the majority of OEMs, they have shown good after-sales service, reliable technical support, and products with price advantage are welcomed by the majority of users. In fact, the domestically-manufactured numerical control system already has serialized products with independent intellectual property rights from low to high-grade, and the high-end numerical control system has actually broken through the restrictions imposed on China by foreign countries.
On the other hand, it also fully shows that many domestic CNC machine tools supporting enterprises are the new force for the industrialization of CNC machine tools in China. People have noticed that China's CNC machine tools supporting companies have a variety of ownership systems. There are a large number of companies that are privately-owned, joint ventures, joint-stock companies, and some are foreign-funded enterprises. They have made important contributions to the development of CNC machine tools in China and have contributed to them. .
The core competitiveness of enterprises is still very low. The current market competitiveness of domestic CNC machine tools is not high, in the final analysis, or the company's core competitiveness is not high. To improve the market competitiveness of domestic CNC machine tools, we must make China's CNC machine tool manufacturing enterprises have the following four capabilities, which is the goal of the industrialization of CNC machine tools. We must form large-scale production on "quantity". This kind of large-scale production is a kind of specialized production. It is different from the highly concentrated large-scale production in the traditional sense, but it is a highly professional social production.
In this kind of socialized production, it is particularly emphasized that there must be a CNC machine tool and main engine factory as a core enterprise, and a large number of NC machine tool supporting enterprises should be used as a cooperative enterprise group that responds to each other. Only in this way can the advantages of the group with increased production capacity, reduced costs, and improved technical level be revealed from the strength. This is the ability of companies to participate in international competition. To master the core technology in "quality". This core technology is through independent innovation, the company's own technology (refers to the unique technology accumulated, applied and formed by the company in the long-term product development, the technology that the enterprise has fully grasped and applied for a long time), and the imported technology (Yes Refers to the introduction of foreign advanced technology or supporting technology of other domestic companies, not the enterprise's own technology, it is the application technology for the enterprise, and the introduction of digestion technology (refers to the technology absorbed by the company from the introduction of foreign technology, including two Sub-development technology is the technology that the enterprise has already mastered. It is an extension and development of the enterprise's own technology. It is re-combined and refined to form a complete technology system with its own intellectual property rights and eventually developed into a core technology for skilled application of the enterprise.
