News side: Many more stable growth opinions have been made to prevent the economy from falling too much. Entering more than August, they began to issue steady growth opinions. Sichuan, Hebei, Gansu, Guangdong, Guizhou, Chongqing, Fujian and other places have all introduced policies to stabilize investment growth and ensure the economic goals of the entire year. The reason why local governments have introduced stable growth has a lot to do with the downward pressure on the economy. Especially in the industrial sector, the country has not completed its goals and most of the localities have not yet completed. Hebei's industrial target this year is 13%, and the actual growth from January to July was only 11.1%. The goal of Sichuan's industrial growth rate is 14%. In the first seven months of this year, it was only 11.3%.

Cost side: After the Tangshan billet fell 30 yuan/ton yesterday, Tangshan 150 billet was reported at 3,150 yuan/ton this morning. In addition, steel thread was raised by 40 yesterday, and Changjiang Steel, Licheng Taihang, and other manufacturers reduced the building materials by 10-30. The price adjustments of most other manufacturers' building materials were held steady; followed by the prices of plates produced by Xining, Tangshan Ruifeng and Hebei Advance. Downgraded by 20-30, Tangshan Guofeng reduced the settlement price in August by 170, and in September the guiding price was raised by 100. From this point of view, yesterday, the mainstream domestic manufacturers to adjust the price of more than a temporary operation; only a few manufacturers are still mixed adjustment phenomenon, and the adjustment is mostly weak adjustment.

** Surface: Yesterday the rebar main contract Rb1401 Gaokaidizou, open 3827, thread to close 3813, due to the pressure on the 3850 line yesterday, the disk finished lower, the trend is relatively weak, is expected to continue to fluctuate the thread today, building materials in some areas fell.

Demand side: Yesterday's end demand release improved slightly, and the transaction also rebounded from last week, and the willingness of sellers to fall significantly weakened.

Taken together, with the continued downward adjustment of the billet price yesterday, combined with the current adjustment of the factory price adjustment is also weak in the adjustment, making the current steel price rebound is blocked; but taking into account the end demand release has improved, especially the volume of the improvement, As a result, the willingness of the commercial banks to continue to decline has weakened significantly. Therefore, in a comprehensive view, it is expected that the current mainstream trend will enter stable, slightly turbulent, and strong adjustments. Among them, the average price of rebar in the mainstream market today is adjusted by -10 to 10 yuan per ton, and the average price of 20mm tertiary rebar in the mainstream market fluctuates between 3640 and 3660 yuan per ton; today's plate prices in the mainstream market will be adjusted. 0 ~ 10 yuan / ton, the average price of 20mm plate in the mainstream market fluctuated between 3690 ~ 3700 yuan / ton.

Our company have German SEW Motor, Japan Mitsubishi Controller. Our own brand Hofic servo motor and controller. Chinese famous brand SEJ motor and Holip controller.

About our German SEW Motor and Japan Mitsubishi Controller: It is easy to find the ideal energy-efficient motor for your application at SEW.

A comprehensive braking concept and cost-optimised built-in encoders ultimately complement the motor range. Comprehensive braking concept and combinations i.e. up to three different brake sizes per motor size featured in the range: Cost-optimised built-in encoders integrated into the motor. Motors for efficiency classes IE1 to IE4.Compact design saves space and costs. Future-proof, also as regards environmental protection (standards). Reduction in operating costs when using energy-efficient motors; our energy-efficient motors conform to the efficiency classes.

About servo High Speed Door Servo Control System: Our rolling gate servo control system is suitable for high speed and high usage soft and hard rolling gate. The whole system is in a small and light package, it has high torque and high operating speed, lower noise, high reliability, smooth and soft operating curves, it`s suitable for high speed and usage environment. The rolling curtain can be controlled by pull switch, push button, Bluetooth, ground radar, ground magnetic sensors. Operating Speed: 1M/s; Operating Width: <16 ㎡; Daily operating time: >2000 time; Rated voltage: 220v; Rated Output: 0.75 KW/1.5KW.

The system can operated via: 1) control box; 2) inching electronic control; 3) continuous automatic operation; 4) emergency stop; 5) single side operation box; 6) time delay; 7) ground radar and/or magnetic sensors. Please refer to Wiring Terminal for eternal connections.

System has fuse/safety wire shutdown switch for three-phase power protection, fuse/safety wire for operating circuit protection, and temperature sensing relay for motor protection.

Stroke Controller utilizes absolute value encoder. Connect the absolute value encoder and reducer via encoder`s axle, and fix the wings on to the reducer, than insert the aviation plug into plug receptacle.

The mounting screw for the control box must inspect regularly to prevent screw been getting loose and falling off. Check the internal and external wirings. Check and change the oil for the redactor on regular basis.

Precision: The system use Full closed-loop servo control and Double Encoder design. This is to ensure long operating life and to prevent overshooting during operating.

Stability: The system utilizes integrated design concept, in order to simplify internal wiring and prevent any function caused by wiring and terminal connections.

High Speed: Motor max speed is 2500 rpm; door max operating speed is 2 m/s.

Smooth: The torque servo system can adjust torque to the load automatically, and its speed curve mode step less speed regulating to ensure a smooth operation.

About SEJ motor and Holip controller: Three-phase asynchronous motor with magnetic brake has broad uses, It is suitable for various mechanical main drive and auxiliary drive, and it is also used for various required rapid stopping and correct positioning. The braking time within 0.2 second. Electric motor is added the DZM series direct current electromagnetic arrester by the basic series(Y series) electric motor.The protection class of electric motor part is IP44,the arrester part is IP23.if be applicable to bad environment can also make the arrester part into IP44,but customer have to put forward a special request while ordering,the manufactory can design a manufacturing exclusively. Its structure diagram is picture 1 and 2,picture 1 is the structure with hand release.Picture 2 is the structure without the hand release.Its operating principle BE, after being to make the retardation coil(6)to connect direct current power supply,because of the function of electromagnetic force,electromagnet(7)attract gag bit(5),and compress spring(24),make arrester disc(2)away from the friction surface of the gag bit(5)and shield(26)(the electrical motor can immediately operate normally).When the power supply cuts off after,the electromagnet(7)loses electromagnet force,the spring(24)releases the gag bit(5)and compress tightly to arrester disc(2),the arrester function,stop(the motor shaft)quickly,make electric motor shop turning to move,for the second time connect power supply will repeat above-mentioned action.
