Steel pretreatment line steel technology in the processing refers to the former (that is, a state of raw materials) for shot blasting the surface rust and painted with a protective coat of processing technology. After pre-treatment of steel products can improve the mechanical and corrosion-resistant metal components ability of anti-fatigue properties of steel, extending its life; but also can optimize the production process of steel surface, and is conducive to cutting machine CNC cutting and precision blanking . In addition, pre-processing of steel as a result of comparing the shape of the rules in favor of mechanical and automated spray paint rust, so the use of steel pre-treatment can enhance the efficiency of clean-up, clean-up operations to reduce labor intensity and the pollution of the environment. In recent years, as a result of the use of PLC control, automation equipment, greater emphasis has been improved.
Key technology and assurance measures - we do better...
Workpiece conveyor system:
1. One of the roller sides has steel plate to arrange the roller, to be convenient to load the material.
2. The whole workpieces conveyor system is frequency timing, not only to synchronously running, but also can individual operate.
3. The roller of Shot blast cabinet has special wear-resistant jacket.
Shot blasting cleaning chamber
1. Workpieces detect devices are out of the shot blast cabinet to avoid the shot and power dust. 2. With Switzerland +GF+ shot blast Wheel, shot blast quantity are large, the life of the blade more than 600 hours.
3. Workpiece height measurement, automatically adjust the open of the shot valve.
With secondary sweeping and secondary blowing
Shot cycle purifying system
1 Elected to adopt full curtain air separator, 2 The use of a dedicated core polyester hoist belt, 3 Projectile controller controlling the use of gas 4 Ball point of the circulatory system has the power failure alarm function
Shot dust collecting system
With large-scale cyclone + filter dust catcher. Power dust exhausting less than 80mg/m3
Painting spray chamber
The two set high compressed airless painting pump detecting device,running system and gun spraying device can avoid fume disturb and improve the running
With dielectric heater and sirocco cycle philosophy make the best of energy. In the drying chamber the temperature can be adjusted among 40--70°C.the plate chain conveyor system add partial-round to solve the machine malfunctions
Fume filter and harmful gas purifying device
Fume filter cotton is made of glass fibrin and non-woven fabrics. It takes one year to maintenance by activated carbon adsorption harmful gases.
Electric control system
With PLC control, computer dynamic simulating monitoring system can carry out the producing line automatically control
Shot blasting chamber
Control center, Failure alarm
The specific characteristics
Specifically for cleaning steel plates (plate width of 2 to 5 meters, the thickness of 3 ~ 100mm) of the specific characteristics, in order to enable better cleaning results, especially when clean-up to prevent the deformation of thin steel plate, our company designed special steel plate pretreatment line.
Specific features: (1) Blasting up and down the two devices-one mapping, offset the impact of projectiles on the plate, and to prevent deformation of thin steel plate. (2) Blasting room Steel import and export special designs made to prevent the shot ball out of room (3)Increased clean-up device side brush cleaning system, completely remove the upper plate of the shot ball. (4) Pill is expected to adopt a double circulatory system hopper hoist, overflow induction pill sand separator. (5) For wide-plate, using four spray gun, up and down the two, at the same time painting.
We go further...
OMRON temperature control system electrical components, the use of OMRON PLC, industrial control computer for the use of PC monitor dynamic simulation.
Pill alarm function expected failure of the circulatory system. If a device (such as the pill sand separator, bucket elevator, screw conveyer) broke down, it will automatically stop, at the same time the equipment is located will also be automatically stopped.
