Product Application
? 1?Hot dip galvanizing line
The purpose of the Continuous Galvanizing Line (CGL) is to apply a coat of zinc onto the surface of steel sheets in an effort to increase their corrosion resistance. There is a wide range of control of zinc coat thickness, and the galvanized steel sheets are used for a broad range of purposes, including construction materials, automobiles and electrical appliances.
(2) Color coating production line
This is a pre-coating line that forms coats through advance application and baking of coating materials onto strips produced by Continuous Galvanizing Lines (CGL; to enhance corrosion resistance) and Continuous Annealing Lines (CAL; to improve properties, such as strength and elongation). It is an add-on for visual aspects of strips, such as color and gloss, as well as for protective elements, such as weather and corrosion resistance.
(3) pickling line
Pickling is a metal surface treatment used to remove impurities, such as stains, inorganic contaminants, rust or scale from ferrous metals, copper, precious metals and aluminum alloys.A solution called pickle liquor, which usually contains acid, is used to remove the surface impurities. It is commonly used to descale or clean steel in various steelmaking processes.
(4) Hot dip galvanized steel coils
It is ideal for a wide range of applications,such as pre-engineered buildings, architectural panels, roofing, siding, cladding, and many other building components.and also used back plate of appliance; wide range of construction, furniture industry, transportation industry, etc.
(5) Color coating steel coil
Industrial / domestic roofing and wall cladding,Cold storages and ware houses,False ceiling, interiors venetian blinds,Air ports, atriums in malls and showrooms,White goods (appliances) such as refrigerators, deep freezers, washing machines etc.Electrical control panels,Roofing tiles,Drum ends,Housings & casings,Industrial furniture & racking,Office furniture,Bus bodies, railway coaches and luxury coaches etc.
(6) Hydraulic machines
In the machine tool industry, at present, 85% of the machine drive system adopts hydraulic transmission and control, such as grinding machine, milling machine, planer, broaching machine, press machine, shearing machine and combination machine tool etc.In metallurgical industry, hydraulic technology is adopted for electric furnace control system, control system of rolling mill, open-hearth loading, converter control, blast furnace control, strip running deviation and constant tension device.Widely used in engineering machinery hydraulic transmission, such as excavators, tire loader, truck crane, crawler bulldozers, cranes, motor scraper, roller grader and vibration, etc.In agricultural machinery, hydraulic technology is also widely used, such as combine harvester, tractor and plough.In the automotive industry, hydraulic suvs, hydraulic self-discharging vehicles, hydraulic high-altitude operating vehicles and fire trucks are all used hydraulic technology.In the textile industry, there are plastic injection molding machines, rubber vulcanization machine, paper machine, printing press and textile machine, etc.In the shipbuilding industry, the application of hydraulic technology is very common, such as hydraulic dredger, salvage vessel, piling vessel, oil production platform, hydrofoil, hovercraft and auxiliary engine.In recent years.And tracking system in the sun, the wave simulator, the ship driving simulator, earthquake reappearance, firing rockets help pei, space environment simulation and high-rise building shock system and emergency brake device not ready, also adopted the hydraulic technology.All in all.Hydraulic technology can be used in all fields of engineering, where there are mechanical equipment.
(7) CMC-NA
For oil, natural gas drilling, digging Wells, etc.CMC is used as a sizing agent for textile and printing and dyeing industry textile industry, and it is used for the yarn sizing of cotton, silk wool, chemical fiber and blended fabric.For paper industry CMC can be used as paper smoothing agent and sizing agent in papermaking industry.Adding 0.1% to 0.3% of CMC in the pulp can increase the tensile strength of the paper by 40% ~ 50%, increase the compression rupture by 50%, and increase the knead by 4-5 times.CMC can be used as dirt adsorbent in synthetic detergent.Daily chemicals such as the toothpaste industry CMC's glycerine solution used as the gum base of toothpaste;Pharmaceutical industry used as thickener and emulsifier;The CMC water solution is increased and adhered to the plankton concentration.It is used in ceramic industry for the adhesive, plasticizer, glazing agent, fixing agent, etc.Used for building, improving water retention and strength.Used in the food industry, food industry high substitution degree of CMC for ice cream, canned beer, on the surface of the instant thickening agent, foam stabilizer, etc., in the process of jam, sugar juice, fruit, dessert, ice cream beverages as a thickener, binder, or due to the agent.The pharmaceutical industry chooses the appropriate viscosity CMC as the adhesive, disintegrating agent, suspension agent and so on.China Water-cooled Hydraulic Station
