Steel pretreatment line steel surface shot blasting before welding process and coated with a protective primer equipment, equipment of about 70 meters and weighing about 150 tons. The equipment consists sent roller, rain water and sewage cleaning device, a warm-up room, shot blasting systems, abrasive cleaning chamber, the intermediate roller, spray booth, drying room, coding, printing, sending roller, shot blasting dust removal system mist processing systems and electronic control system components. Steel pretreatment can improve the corrosion resistance of mechanical products and metal components, improve the fatigue performance of steel plate, extending its life; also can optimize the surface of steel fabrication status, CNC cutting machine cutting and precision blanking. In addition, because the steel regular shape, prior to processing, is conducive to mechanical descaling and automated spray paint, so the use of steel substrates can greatly improve the efficiency of clean-up operations, reduce labor intensity and the environmental pollution clean-up operations.
In recent years, due to the programmable logic controller to control the degree of automation of the equipment to get a greater improvement in the level.
Note: clients of the rainy weather in the South and Northeast regions, require preheating device (electric heating, far infrared heating, gas, heating fuel and other means), drying. Pretreatment line speed, I can meet any user's requirements, including increasing the power of the blast wheel series shot blasting machine, etc..
Key technologies and assurance measures
With the rapid progress of science and technology, computer and automatic measurement and control instruments are universally applied in the machinery manufacturing industry, a few decades ago can not achieve the functionality is now a breeze. The company followed the international trend, temperature transmitter, rotary encoders, and other components used in steel pretreatment line, full line of computer monitoring (monitoring center, to replace the old analog screen), CCTV monitoring, and can be configured according to user requirements automatic coding instrument and automatic barcode printing device. Computers and other high-tech mechanical products is an inevitable trend.
