At present, all domestic steel enterprises and machining industries have been cutting with Xiapu gas (propane gas) in billet cutting and steel sheet cutting. There are a lot of defects and deficiencies in the cutting with Xiapu gas. On the one hand, the vaporization of Xiapu gas is incomplete, and some gas will remain at the bottom of the bottled Xiapu gas cylinder. The unit often uses the hot water to heat the bottle. Even so, There is also a part left in the bottle, especially in the winter, where more than one-third of the gas remains in the bottle, causing huge waste. On the other hand, Xiapu gas is bottled and prone to safety accidents. The safety hazard of Xiapu gas station has always been the key investment and security inspection project of the unit. Beiman Special Steel Beixing Company 500,000 t production line, there are four-machine four-flow billet continuous casting machine producing 250mmX280mm, there is production! 450mm,! 550mm,! The 650mm three-machine three-flow round billet continuous casting machine has an annual output of several hundred thousand tons of steel-making raw material scrap, which requires a large amount of Xiapu gas for cutting. The natural gas in Daqing gas field has been transported into the Beiman Special Steel Plant through pipeline transportation. After natural gas is burned, no waste residue or waste water is produced. It has the advantages of relatively safe use, high calorific value, cleanliness and low price. How to achieve energy substitution, improve economic efficiency, promote scientific and technological progress, and solve safety hazards are new issues facing Beiman Special Steel. The main technical solutions and measures to achieve natural gas replacement Xiap gas cutting technology must solve the following technical problems. When the natural gas is cut, the crack is large, the cutting speed is slow, and the cutting quality is not good. However, after adding the additive catalysis, the flame length, the heat value and the cutting ability are increased, and the cutting effect is effectively improved. Beiman special steel technicians communicated with relevant manufacturers, and went to the same industry to use the manufacturers to inspect, decided to use natural gas and additive blending technology instead of bottled Xiapu gas technology to cut the online continuous casting billet. 1.1 Solving the problem of natural gas decompression When the natural gas is piped to the point of use, the pressure does not match the pressure required for cutting, which is much higher than the pressure at the point of use, so it is necessary to carry out decompression treatment. 1.2 Solving the technical problem of natural gas and additive blending Natural gas is gas, and additive is liquid. How to achieve uniform blending of the two to ensure cutting quality is the key to the problem. 1.3 The realization of automatic control of all production processes to achieve scientific and technological progress, automatic control of all production processes, cancel the original Xiapu gas station, the original busbar, the original artificial gas cylinder handling work. Process and technical characteristics 2.2 Main technical features The advanced complete set of pressure reducing device is used to automatically filter the gas, realize automatic alarm for pressure, automatically cut off, equipped with advanced metering and flow control device, and adopt dual-channel (standby) Security facilities. The mixing facility adopts advanced distribution towers, automatic control pumps, additive storage tanks and other facilities, with uniform mixing, excellent equipment, small floor space and less equipment maintenance, which is basically remote monitoring and control. High degree of automation. The control system based on PLC and industrial computer fully realizes the automatic control of the whole blending process, and has the function of printing reports, strong anti-interference ability, suitable for industrial environment, display device process parameters, working status, alarm prompts, etc. With a good and intuitive man-machine interface and dialogue function, operation and maintenance is simple and easy. The actual effect is compared with the original Xiapu gas cutting technology by natural gas and additive blending technology. After the transformation, the flame penetration force is very strong. The cut (upper page 42) is basically the same as the set material type, but only The material type has a slight adjustment. The design of the import and export guides generally meets the process requirements, but the K1 inlet sometimes scrapes the wax and sticks the steel, and the rest are more reasonable. The specific measures to be improved in the next step, because the K1 imported guide slab straight section is too long, shorten the K1 import guide slab straight section 20mm, to reduce the slats as neatly cut, and the gap is very small, greatly reduced Cutting time reduces material consumption. Only the gas comprehensive cost saving rate reached 48%, Xiapu gas officially withdrew from the production site, reducing the handling of 10 Xiapu cylinders per day, improving work efficiency and reducing safety hazards. It is estimated that the cost of natural gas instead of Xiapu gas-cutting steel is 2.88 yuan, and the annual direct benefit can reach more than 1.95 million yuan, which does not include some materials saved due to the improvement of cutting quality, incision and no dross. Cost, and annual carbon dioxide emission reduction 1 4 Conclusion The use of natural gas and additive blending technology to replace the bottled Xiapu gas for cutting applications, saving energy, reducing costs, simplifying the operating procedures, promoting technological progress and reducing safety risks . At present, only some steel enterprises, machine tool factories and shipyards with conditions in the country have adopted this technology. From the perspective of economic benefits and social benefits, the promotion prospects are very broad. The phenomenon of sticking steel. There are three types of Dip switch led batten lights, Change CCT Light, Change Power Light, and Change CCT and Power light.

In other words, this batten light can change the color temperature and power. It is mainly possible to change the color temperature and power by turning the DIP controller inside the lamp body. Moreover, you only need to press the button on the side of the light to open the light body, which is very easy to operate.
The function of changing color temperature and power is very suitable for stock. Before shipping, you can set the color temperature and power that your customers want.
The adjustable range of color temperature is: 3000k/4000k/5000k, 4000k/5000k/6000k.
The power adjustment range is: 5 /10 /15 /20, 5 /15 /25 /30, 10 /20 /30 /40, 10 /25 /40 /50, 10 /25 /40 /50, 20 /30 / 50/60.
This batten light is suitable for warehouses, shops, corridors, offices, factories, and other indoor places.
