Vertical disassembly cylinder machine, pressure test bench and test frame, laser cladding machine...... Recently, walking into the production workshop of Liupanshui Ruijiawei Metal Surface Technology Co., Ltd. (hereinafter referred to as "Ruijiawei Metal Technology"), what catches my eye is the scene of high-speed rotation of various processing equipment, and the workers in red overalls are methodically operating the machine in the low sound.
Rui Jiawei Metal Technology Co., Ltd. is a subsidiary of Anyang Ruiheng CNC Machine Tool Co., Ltd., in 2023 Anyang Ruiheng and Liupanshui High-tech Zone signed an investment promotion agreement, relying on the rich coal and steel resources in Liupanshui City and the surrounding areas, the establishment of Liupanshui Rui Jiawei Metal Surface Technology Co., Ltd., the company rents 5,000 square meters of standardized factory buildings in the high-tech zone, and invests in the construction of an annual processing of 20,000 square meters of metal surface projects, mainly engaged in metal cutting machine tools, metal processing machine tools, general equipment maintenance, maintenance, Maintenance, wear-resistant treatment of metal materials, R&D and production of standard consumables for iron and steel enterprises, etc., provide industrial supporting services for energy and mining equipment enterprises, and help local coal and iron and steel enterprises reduce costs, increase efficiency, improve quality and expand capacity.
In the propaganda board in the company's production workshop, the laser cladding flame spray welding process, the repair hydraulic support process, and the inner hole copper melting technology process are clearly visible.
"The company currently has 4 processing lines, and laser cladding technology replaces the traditional treatment technology. One equipment can process 0.6 square meters within one hour, and more than 300 square meters a month in two shifts, which can fully meet the needs of Zhouben Coal Mine. Liu Keke, deputy general manager of Ruijiawei Metal Technology Technology, said.
Ruijiawei Metal Technology is committed to the repair of hydraulic supports in coal mines, the repair and remanufacturing of column dry jacks, laser cladding, copper melting and additive on the inner wall, the maintenance of scrapers, the laser cladding of wear-resistant layers, the laser cutting of wear-resistant plates and plates, the heat treatment of roll surface in the steel industry, phase change hardening, shaft repair, etc., to achieve a significant increase in service life. Among them, the laser cladding technology is the use of high-power laser beam to gather the characteristics of extremely high energy, which can instantly melt the surface of the processing equipment and automatically send it to the laser beam synchronously, and completely melt the self-melting alloy powder, and quickly solidify to form a dense cladding with very low dilution and matrix metallurgy, so as to achieve the purpose of surface modification or repair, which not only meets the requirements for the specific properties of the material surface, but also saves a large number of valuable elements.
Not only that, the company also independently developed high-precision CNC lathe series products, with high precision, high rigidity, high efficiency and other characteristics, dedicated to the cutting of super-hard wear-resistant metal materials, high machining precision, good finish, completely using the "turning instead of grinding" process to cut the surface of the hydraulic support after laser cladding, to solve the problem of processing difficulties caused by high surface hardness after laser cladding, greatly improving the efficiency of processing high-precision CNC lathes, and creating great economic benefits for enterprises.
"Accessories like this hydraulic support, if you buy it, it will cost about 3,000 yuan, and it will only cost more than 1,000 yuan to repair, and the mission after repair is 2 times longer than the life of the new purchase. Zhang Shaoyun, general manager of Ruijiawei Metal Technology, told reporters that through the laser cladding process, the surface of metal fittings such as hydraulic supports can be significantly improved wear resistance, corrosion resistance, heat resistance, oxidation resistance and electrical characteristics, etc., to achieve the perfect combination of technology and art, not only can the failed parts be restored, but also significantly extend the service life of new parts, and directly reduce the mining cost of energy mining enterprises.
Since entering the high-tech zone, Ruijiawei Metal Technology has established a good strategic cooperative relationship with major coal mines and machine repair factories in Liupanshui by means of multi-mode cooperation methods such as equipment sales, leasing and co-construction of processing stations, and will accelerate the layout of the surrounding market in 2024 to achieve the goal of exceeding 20 million yuan in turnover.
Zhang Shaoyun said that in the next step, Ruijiawei Metal Technology will expand its business scope, make an overall development plan for the southwest market, continue to adhere to the development direction of "modernization, intelligence, and environmental protection" and the concept of "green metal surface treatment", help enterprises reduce costs and increase efficiency, improve quality and expand capacity, and help the high-quality development of Liupanshui economy.
