Recently, the 1980mm ultra-wide cold-rolled panel and the 1805mm ultra-wide-width zinc-iron alloyed steel panel developed by Maanshan Iron & Steel Co., Ltd. have passed the trial certification of domestic automobile OEMs and entered the small-batch supply phase. This indicates that Maanshan Steel has become the second domestic company to have Iron and steel companies that produce ultra-wide cold-rolled and galvanized automotive panels.
The wide-spec cold-rolled and galvanized automobile panels are mainly used for large-size coverings such as car side walls and roof covers. The technology is complex and difficult to develop. It is an embodiment of high-end technology, advanced management, and fine manufacturing. In order to cope with the increasingly fierce market competition, this year, Masteel set up an automotive board propulsion office to accelerate the development of automotive panel products in terms of research and development, production, sales and after-sales service capabilities. It will also develop wide-range cold-rolled and galvanized panels as an automotive panel product. The primary task of developing capabilities, improving management and manufacturing levels is to grasp. For the characteristic requirements of cold-rolled and galvanized wide-width automotive panels, a project research team was set up to formulate detailed process work plans. After six months of continuous technical breakthroughs, the successful production of qualified ultra-wide cold-rolled, galvanized automotive panel test material. In September this year, ultra-wide cold-rolled automotive panels and super-wide zinc-iron alloyed automotive panels were all successfully tested at one time, and the product quality reached the level of domestic advanced steel mills.
LINA Extrusion Pelletizer
LINA extrusion pelletizer is in the leading level in domestic industry, LINA produces different types granulation extruder such as hot-cutting and air-cooling mode, under-water pelletizing mode, water strand extrusion pelletizing mode and water ring extrusion pelletizing mode to meet the needs of different material.
Material feeding is an important process of the whole granulation process. To achieve effective and efficient material feeding process, LINA adopts twin-taper and twin-arm feeding methods to meet the needs of all kinds of materials.
LINA Twin-Taper Granulation Machine
LINA twin taper granulation machine, it is also called double-cone pelletizing machine, which adopts forced feeding by the two tapers. In order to achieve the continuous and fully automatic process by forced feeding the mixed metal lump, LINA double cone pelletizer reduces the crushing links which exists in traditional granulation of metal powder. LINA twin taper granulator is specialized for the pelletizing of high-hardness, strength and wear resistance material, including stainless-steel powder, iron powder, magnetic powder, zirconium oxide and ceramic powder.
LINA Rubber & Plastic Pelletizing Production Line
LINA rubber & plastic granulation production line is applied for a variety of rubber masterbatch, rubber additives, chemicals auxiliaries and other masterbatch granulation. The whole process is Dispersion Kneader → Automatic hoist → Forced dual-arms feeder → Single screw extruding granulator → Dropping type-air cooling die face hot cutting granulator →Level 1 cooling separator → Level 2 cooling separator → Level 3 cooling separator →Taiwan Transparent vibration distribution sieve → Storage bucket.
Advantages of LINA Granulation Extrusion Line (Main techniques and drawings are from Taiwan, Japan and so on.)
1. The unit has the whole unit process chain, sound and light failure alarm and fast lock fault point and other control functions. All parts that are in contact with the material are made of stainless steel.
2. High accuracy of temperature control system to ensure the temperature sensitivity of the material.
3. It adopts the drop type separating method after cutting process, to avoid Particle agglomeration and ensure particle cooling.
4. Feeding system of the pressing machine adopts heater and reversing device to solve problem of power outage, material crash and cleaning.
5. Especially, the barrel and die head adopts advanced foreign techniques to ensure and control the dangerous occurred when the pressure is uncontrollable. The honeycomb filter plate is easy to clean and quickly change the mesh and the die head t easy to leak.
6. The hoist adopts automatic return technology to ensure the working efficiency.
7. The technological combination of dual-pull forced feeder and single screw not only meet the high requirement of secondary continuous mixing, but also solve the problem of time and power consuming of traditional working process.
