Produced by Chongqing Hesheng Longgang Technology Co., Ltd. (manufacturer) Basalt fiber reinforcement (new material to replace reinforcement) Product Description: basalt fiber reinforced bar (BFRP) is a new composite material formed by pultrusion process. It is made of basalt fiber as reinforcement, resin, filler and curing agent. Now it has been widely used in construction, highway and bridge constructionã?? Basalt fiber reinforcement can completely replace ordinary steel reinforcement and deformed steel; Compared with ordinary reinforcement, it has strong advantages: (see Annex for technical parameters) 1. The cost is the same as that of ordinary reinforcement; 2. The strength is 200% of the ordinary reinforcement with the same specification and diameter; The tensile strength reaches 1100mpap; The reinforcement is only 450MPa, 3. Basalt fiber reinforcement, especially with high acid, alkali and corrosion resistance, is a kind of electrical insulator that will never rust. 4. Basalt fiber reinforced bar, which is non-magnetic. It has high tolerance to the moisture concentration in cement mortar and the penetration and diffusion of carbon dioxide, and can prevent the corrosion of concrete structure in harsh environment, so as to improve the durability of buildings and bridges. 5. The specific gravity of basalt fiber reinforcement is 2.1g/cm3; The specific gravity of steel and reinforcement is 7.85/cm3; The diameter weight of the same specification is 370% lighter than that of steel reinforcement, and the strength is 200% of that of steel reinforcement. 6. The physical properties of basalt fiber reinforcement are higher than that of steel reinforcement, and the cost is the same as that of steel reinforcement, which is of epoch-making significance to replace steel reinforcementã??

The types of flight bar can be classified according to different sizes of the main engine, such as 630 flight bar, 730 flight bar, 764 flight bar, 800 flight bar, 830 flight bar, 900 flight bar, 960 flight bar, 1000 flight bar, 1200 flight bar, 1250 flight bar, 1350 flight bar and so on. Of the flight ba, the machining process can also be to differentiate the types of flight ba, such as forging flight bar, scraper flight bar and the quality and performance in all aspects are better than the latter, while the latter is more relative to the price advantage, customers can choose according to the different situation of coal mine, and forging scraper unit from the manufacturer and the use of perspective is a good choice. The above is the Henan Shuangzhi machinery xiaobian flight bar type for your share, hope to just involved in the scraper parts industry friends to help, more scraper parts knowledge or consultation, please continue to pay attention to the Official website of Henan Shuangzhi machinery understanding.
Rebar bending hoop machine belongs to an improvement of the structure of steel bar bending machine. The utility model includes a reducer, a large gear, a small gear, and a curved disc surface, which is characterized by the structure: a two-stage brake motor and a reducer are directly connected to perform a first-stage deceleration; The curved disc surface is always driven to rotate; the central axis hole and several curved axis holes are provided on the curved disc surface; the positioning square bars on the worktable surface are respectively provided with several positioning axis holes. Because the two-stage brake motor and the reducer are directly connected for one-stage deceleration, the input and output revolution ratios are accurate, the bending speed is stable and accurate, and the automatic conversion speed can be controlled by electric, and the brake can ensure the bending angle. Using the positive and negative rotation of the motor, the rebar is bent in two directions. The central axis can be replaced for easy maintenance. Intelligent control can be used. 1. Straightening system: the multi-wheel group straightening machine structure is adopted, which is straightened by two sets of horizontal and vertical multi-wheel straightening. The straightening system has position mobile memory detection. Replacing different diameter steel bars, the straightening wheel will automatically go down or up Adjustment to achieve rapid steel bar straightening (patented technology), shorten the steel bar straightening time, the entire process is automatically completed, multi-wheel group synchronously draws the steel bar, the pressure between the wheel and the steel bar is reduced, and the traction force is small, thereby causing energy consumption and steel bar loss cut back. 2. Cut-off system: Cut-off is equipped with brakeless brake control device (this device is our company's invention patent), which supports high-speed frequent start-up shear, which greatly improves the reliability and durability. 3. Bending system: driven by imported servo motor, the bending arm can be quickly rotated and telescopic, from eccentric shaft type to straight reciprocating structure, eliminating eccentric loss parts. 4. Control system: adopt advanced PLC program control, color touch screen display, key input to reduce the damage to the touch screen due to poor environment. Built-in a variety of different shapes of stirrup graphics, the key parts are imported brand-name products, with fault recognition and alarm functions. 5. Operation console: The operation panel of the new model is integrated with the main unit, and can be moved from side to side, effectively avoiding the defects such as large occupation of the operation console and unsafe control cables exposed on the ground. contact
Thermal lance also known as burning bar or thermic lance, made by hollow mild steel pipes filled with a number of iron wires, which is a powerful efficient cutting tool by high purity oxygen flow through the interior of the lance to create extraordinarily high temperature from 3,600 to 4,426�°C for cutting through just about anything. Thermal lance can be used whenever some ferrous and non-ferrous materials must be removed or cut into pieces, like sand casting riser cutting or ladle furnace tapping. When molten material is spilled, it can be allowed to solidify and then cleaned up with thermal lance. For coastal buildings, interior concrete sometimes breaks down to produce what is called concrete cancer, but thermal lance can be used to remove this degrading concrete so that replacement material can be packed in. These characteristics of the thermal lance make it a particularly efficient and cost-effective method of cutting steel and cast-iron materials too thick to be cut with a normal oxy-acetylene torch. In the case of thicker materials, during the operation, the lance tube will be consumed by the intense heat at the cut point and should be discarded once it becomes too short to be safely used.
Prestressed threaded bar (or PT bars) are high-strength, high-precision, straight-line steel bars with external threads on the entire steel bar. The steel bar can be screwed onto the connector with internal threads at any section or screwed with a threaded nut with internal threads for anchoring. The utility model has the advantages of simple connection and anchorage, strong adhesion, safe and reliable tension and anchorage and the like, and is a novel material for developing prestressed concrete component. Prestressed Bar are currently used to anchor and support the dam body form of the dam foundation. In the cable-stayed bridge, fully threaded bars are used as the main ribs and bridge foundations of the main tower. The use of fully threaded steel bars saves steel, reduces component area and reduces component weight. The continuous external thread is hot rolled. The shape of thread bar is shown as following figure. The main dimension ranges from 15mm-50mm and the grade ranges from 500/630Mpa to 1200/1330Mpa.
