Shield tunneling machine is a tunnel boring machine using shield tunneling method. Shield construction method is tunneling machine in tunneling at the same time to build (laying) tunnel "shield" (refers to the supporting segment), it is different from the open construction method. Internationally, generalized shield tunneling machine can also be used in rock formation, but different from the open (non-shield tunneling machine) tunnel boring machine. But in our country, the tunnel tunneling machine used for soft soil layer is habitually called the narrow sense shield machine, will be used for the rock formation to be called the (narrow sense) TBM. According to the working principle, the shield machine is generally divided into hand digging shield, extrusion shield, semi-mechanical shield (local pressure, global pressure), mechanical shield (open-chest cutting shield, pneumatic shield, mud and water pressure shield, earth pressure balance shield, mixed shield, special-type shield).
Cold mill is a new type of cold steel mill processing equipment. The machine can be hot rolled wire rod diameter between 6.5 mm to 12 mm, hot rolled disc circle processing into the finished product specifications diameter of 5 mm to 12 mm cold rolled ribbed steel bar. The cold-rolled ribbed steel bar rolled by cold rolling mill is the replacement of cold-drawn low carbon steel wire in prestressed concrete members. In cast-in-place concrete structures, the grade I steel bar can be replaced to save steel. It is a better kind of cold-worked steel in the same kind. If speed regulation is not required in the process of cold rolling mill, AC motor can be used; If speed regulation is needed in the process of cold rolling mill, DC motor can be used.
Hot rolling mill is made of continuous casting slab or first rolled slab as raw material, which is heated by stepping furnace and dephosphorized by high pressure water after entering roughing mill. The roughing mill material is cut head, tail and then entered into finishing mill to implement computer controlled rolling. After final rolling, it passes through laminar cooling (computer controlled cooling rate) and coiling machine to become straight roll. The head and tail of straight hair roll are often tongue and fish tail, the thickness and width accuracy is poor, and the edge often has wave shape, hem, tower shape and other defects. After finishing the straight hair coil by cutting the head, cutting the tail, cutting the edge, straightening and leveling several times, then cutting the plate or rewinding, it becomes: hot rolled steel plate, flat hot rolled steel coil, slitting strip and other products. The hot rolled pickling plate roll is formed after removing the oxide skin by pickling and applying oil.
Injection molding machine is also known as injection molding machine or injection machine. It is the thermoplastic plastic or thermosetting plastic using plastic molding mold into plastic products of various shapes of the main molding equipment. It is divided into vertical, horizontal and all-electric. The injection molding machine heats the plastic and applies high pressure to the molten plastic so that it shoots out and fills the mold cavity
Forging press refers to the mechanical equipment used for forming and separating in forging and pressing. Forging and pressing machinery includes forging hammers for forming, mechanical presses, hydraulic presses, screw presses and flat forging machines, as well as uncoiling machines, straightening machines, shearing machines, forging manipulators and other auxiliary machinery. Forging and pressing machinery is mainly used for metal forming, so it is also called metal forming machine tool. Forging and pressing machinery is formed by applying pressure to the metal. Large force is its basic characteristic. Therefore, it is mostly heavy equipment, and the equipment is equipped with safety protection devices to ensure the safety of equipment and personal safety.
Cementing truck is a cementing equipment controlled automatically by computer. It is a high performance automatic mixing and grouting equipment integrating mechanical system, automatic control system and hydraulic system. The mixing system is equipped with an axial-flow mixer and an automatic density control system to accurately prepare the cement paste as required, and has a repeating cycle secondary mixing function to achieve real-time control and regulation of cement paste density.
Well logging truck is a kind of comprehensive well logging truck used in oil field. It has the functions of logging instrument truck, cable winch and crane, saving vehicles and drivers, convenient operation and reducing half of the load of the crane. It is the instrument of the devices on the car and cable winch focus on crane, such as limited by the car, it can be installed on the bogie beam with steel plate form the platform floor, decorate in the floor to the first two ground tool and around the drum of the cable car, also can install ground tool operation room and control roller and the control room of the crane jib and improve the operation environment.

Track Jacks Track jack a device for raising railway track during ballasting or other track operations. Mechanical track jack is the simplest & sturdiest types of the jacks and widely used in Oil Fields, Railway Track Work,Ship Yards, Mining Operation, Construction &Heavy Duty Industrial Maintenance & Establishments. These Track jacks can be used to lifting both on down and up strocks. They're not only be lowered tooth by tooth but also can be made to tripped off by just moving the trip control.
Carrageenan for Pet Food Utilizes semi-refined carrageenan, extracted from high-quality seaweed, which forms a uniform gel with the proteins in pet food, helping retain a significant amount of moisture and reducing the loss of meat juices. It serves as a natural food additive for pet food production. Advantages of application: 1.Enhances palatability and increases appeal to pets. 2.Improves the product's water and oil retention properties. 3.Suppresses the dissolution and volatilization of flavor components, lowers the water activity of the product, and extends its shelf life.
