Application of legend
Mining machine cutting
Cutting teeth is the key part of the direct cutting coal rock on the mining unit. The main failure mode is wear failure, the main form of wear failure is the end part of the cutting tooth wear, resulting in alloy head off. Generally, the wear resistance and short service life of the common pick is worse, and the strength of the downhole operation is increased, and the production efficiency is reduced.
By means of laser cladding technology, pick the average microhardness HV800, Rockwell hardness HRC; alloy laser of the average microhardness of the pick HV1099, Rockwell hardness 70hrc. The average microhardness of laser hardening cutter for HV750, Luo's hardness to 62 HRC. Laser cladding and alloying process coating and substrate is metallurgical bonding, with high strength.
By experiment, the surface hardness and wear resistance of the end surface of the laser enhanced cutting tooth were significantly improved, and the service life of the cutting teeth was significantly prolonged. Compared with the conventional cutting, the laser cladding section has a long life span of 3-4 times, and the surface of the alloy is 5-6 times longer.
Mining large hydraulic support column
Domestic ordinary column is by surface plating method of bake in a pan to achieve surface anti rust, corrosion, because chrome plated layer wear resistance is poor, its life is 1-1.5 years, chrome plated layer will appear the phenomenon of skin, desquamate, thus emulsion can corrosion of the column surface, influence of hydraulic support the use effect.
The Wuhan Han goldensky Laser System Co., Ltd. the laser cladding of complete sets of equipment, not only few processing steps, controllable parameters (thickness in a certain range continuously controllable) and after processing stainless steel coating is much higher than chromium coating corrosion resistance, fully meet the requirements of wear resistance.
Through the wear serious but not scrapped pillar cladding remanufacturing can reach or exceed the original technology and new product service life, reduces the column the replacement and the maintenance time, improve production efficiency, and can save a lot of money and processing process is clean and environment-friendly, for building the saving type society has a broad and far-reaching significance.
Scraper conveyer is one of the most widely used in coal mine, which is one of the most serious equipment due to wear and tear. This machine is the main transport equipment in coal mining face and roadway. In the fully mechanized working face, it is the operating rail of the coal winning machine and the supporting equipment of the self moving hydraulic support. Because the cargo (coal and gangue), and a chain scraper slide slot in the middle, the middle groove resistance, wear is very serious.
Using a new type of laser hardening technology of laser cladding, in accordance with the friction of the scraper conveyor wear mechanism, in the central groove of easy wear parts of cladding a layer of metal ceramic to enhance central groove wear resistance, meet the equipment remanufacturing technology requirements, to achieve the recycling of the central groove of the.
Application of high power semiconductor laser in laser processing
Along with the development of modern optical technology and semiconductor chip manufacturing technology, increasing the output power of the laser at the same time, restricting semiconductor lasers in industrial application of beam quality of the worst problems also gradually resolved. High power semiconductor lasers have been used in many fields, including metal surface hardening, welding, cutting and marking, and many other processing fields.
Semiconductor laser robot flexible processing complete sets of equipment not only has the advantages of small volume, can also according to need to easily move to restore the online, with up to 50% of the photoelectric conversion efficiency and continuous operation of the highest power stability. According to the company laser technology research center fan industry and trade, company as early as at the end of 2011 on the launch of the semiconductor laser robot flexible processing complete sets of equipment has been widely used in mining machinery, coal machinery, petrochemical machinery, generators and other large machinery parts and components of the laser repair.
At present, the equipment has been a large-scale iron and steel enterprise, which has been successfully used in the repair of large workpiece support roll and flat caps, etc., and mill roll end loop transformation hardening, wear resistance has been greatly improved, and for large turbine generator seat wear parts of the field repair.
