The cold rolling mill is a new type of cold-rolled steel processing equipment. The machine can process hot-rolled wire rods and hot-rolled coils with a diameter between 6.5 mm and 12 mm into cold-rolled ribbed steel bars with a diameter of 5 mm to 12 mm. It has types including 4hi cold rolling mill, 2 hi cold rolling mill, two-ribbed cold rolling mill, spiral blade cold rolling machine, flat steel cold rolling mill. It adopts an electric motor to drag the reinforcing bars and uses the load-bearing rolls, work rolls of the rolling mill to apply force on both sides of the reinforcing bars. The purpose of rolling cold-rolled ribbed bars with different diameters is achieved by changing the size of the gap between the two rolls. The equipment can simultaneously process the warp and weft directions of the base material during the cold rolling process. Under the premise of maintaining the relative balance and stability of the product in the center area of the original cross-section, improve the resistance and compression, still retaining sufficient elongation performance.
4hi Cold Rolling Mill
The 4hi mill is a kind of cold rolling processing machine.It is suitable for the cold rolling of carbon steel, alloy steel, copper, aluminum, etc. It has the characteristics of large rolling force, high precision and strong stability. The four high mill has automatic control function with the full hydraulic machine electricity integration. The machine can automatically balance and center, automatic thickness. It is immensely used to roll down aluminum sheets in different thickness. It is the most advanced in the field of non-ferrous metal cold rolling equipment.
2 Hi cold rolling mill
The 2 Hi cold rolling mill is a two-roller mill, used for the cold rolled of low-carbon steel, non-ferrous metal sheet and alloy powder cold-rolled strip. The machine consists of main motor, gear reducer, herringbone gear seat, universal joint shaft, working machine base, electric control cabinet, etc. The system adopts special rolling mill bearing and the roller material is 9Cr2Mo.
Two-ribbed Cold Rolling Mill
The cold rolling mill adopts two-rib forming and tempering technology. The appearance of the machine is black and blue and the thread is clear and plump. The yield strength and tension are better than ordinary cold-rolled ribs steel and Grade III steel. 500MPa high strength steel fully meet the requirements of the building requirements.
Spiral Blade Cold Rolling Machine
The cold rolling mill machine which is mainly used to produce spiral blades of various specifications. The machine can squeeze the strips of different materials to a variety of sizes of continuous spiral blades through the relative movement of two conic rollers. It is equipped with a hydraulic cutting device for cutting arbitrary lengths as needed. Spiral vane cold rolling mill is an automation equipment that integrates electrical, hydraulic and mechanical devices. It has high precision and stability. Helical vane cold rolling mill has the characteristics of variable frequency operation, compact structure and simple operation. The working speed of the cold rolling machine can be changed according to the actual situation. The helical vane cold mill eliminates the cumbersome and complicated processes.
Flat Steel Cold Rolling Mill
This cold mill is a new kind of cold rolling process equipment. The machine adopts a combination of flat rolling and vertical rolling. It can winds the rolling coil to flat steel of a certain specification. The production line is equipped with analog signal equipment to make the equipment run smoothly and keep the straightness of the product. The mill is equipped with a cold rolling water cooling system to extend the service life of the roller. The rolling mill can produce flat steel products of different sizes and is used in different fields. The Cold rolled ribbed steel bar has been used in buildings, bridges, storage racks, grain bins, car bodies, railway coaches, highway products, transmission towers, transmission poles, drainage facilities, various types of equipment and others.
