Hot-dip galvanized bolts for annealing outside the line!

Hot-dip galvanized bolt external annealing: before the hot-rolled or cold-rolled steel sheet enters the hot-dip galvanizing line, it is first recrystallized in the bottoming annealing furnace or the hood annealing furnace. Therefore, the galvanizing line is not There is an annealing process. The steel sheet must be bonded to a clean, pure iron active appearance in the absence of oxides and other contaminants prior to hot dip galvanizing. This method is to remove the annealed appearance of iron oxide skin by pickling, and then apply a layer of zinc chloride or a solvent composed of ammonium chloride and zinc chloride to protect the steel plate from oxidation. .

Ultrasonic Heat Meters(Ultrasonic Calorimeters) are kind of energy meters measuring the flow rate and heat exchange through the ultrasonic method. The ultrasonic Heat Meters get the heat consumption value through the temperature sensors. The ultrasonic heat meters are mechatronic product based on the microprocessor and high precision sensors. Comparing with the Water Meters, electornic meters and gas meters, the ultrasonic heat meters need much more complicated designs and higher technology demand. Ultrasonic heat meters is kind of high technology products with mechanism, electronics and information technology. At present, the ultrasonic heat meters are more often used in many industries,through Ultrasonic Heat Metering,can accurate to do what you want.

Ultrasonic heat meters are consisting of flow rate sensor, temperature sensor and calculator, which has the advantages in high tense construction and easy installation. We adopt the quality ceramic transducers which guarantee the high accuracy and stability of the ultrasonic heat meters. The ultrasonic heat meters have the characteristics as following: non mechanical movement, non wear and tear, non influence from the bad quality water and low cost maintenance; horizontal or vertical installation; installed in inlet water tube or return water tube according to customers` request (should be chosen in advance); adding the RS485 according to customers` demand to reach the aim of remote meter reading in order to be centralized management.
