Hot Rolled Steel Sheet Production Process The production procedure of HRS is generally as follows: Iron making → steel making → continuous casting (or die casting) → hot rolling process Hot Rolled Sheet production is a rolling procedure that relates rolling steel at a high temperature (usually above 1700°F) and over the recrystallization temperature of hot rolled sheet. When the steel heating temperature is higher than the recrystallization temperature, it can be formed and shaped easily, and the steel can be made to larger sizes. Hot Rolled Steel Sheet is usually cheaper than cold rolled steel because of the fact that it is usually manufactured without any delays and then does not require reheating of the steel (as with cold rolling). As steel cools, Hot Rolled Steel Sheet contracts slightly compared to cold rolling, so there is less control over the size and shape of the finished product. Description of Hot Rolled Steel Sheet Because of its much simpler processing method, hot rolled steel can be easily shaped and formed in any desired form. Hot rolled sheet is one of the most variety of steel in the industry. Because of its ductility, this hot rolled sheet is very advantageous in the production of structural or sectional modules. The main characteristics of hot rolled steel sheets are similar to those of hot rolled steel coils, very similar production procedures and thickness, width, and length define similar physical characteristics, but the post-processing methods are different. In addition, determine the final application and corresponding processing equipment. Application of Hot Rolled Steel Sheet Used in welding and boiler making, hot rolled steel is ideal for construction materials such as railroad tracks and l-beams. Another advantage of hot rolled steel is that the surface finish of hot rolled sheet is not an issue. Typical uses consist of: Structural sections Whether resistant structures Pressure vessels Structural parts, vehicle chassis wheel rings Shipbuilding, marine application HUARUO Industrial Group Co., Ltd is a professional prepainted galvanized steel coil manufacturers, we provide Huaro steel, such as steel slab, steel billets, hot rolled steel, hot rolled coil, cold rolled steel, cold rolled steel coil and etc. Want to know more, please contact us.

What's the Difference of A Managed POE Switch? Except for all the features of unmanaged POE switch, Managed POE switch also provides the configuration, management, and monitor on your LAN. Besides, a Managed POE switch enables more control over your LAN traffic and offers advanced features to control that traffic with certain management functions. In summary, let's refer as below. A managed POE switch also communicates across networks It provides built-in security functionality It offers diagnostic functions It can identify possible failures in the network and prevent faultily Detects faulty parts and report How Does A Managed POE Switch Work? Basically a managed POE Switch work under such management features. 1. Quality of Service (QoS) QoS can identify the most important data traffic among all the network traffics so that it can manage available bandwidths to allow the most important traffic pass first. We can configure by certain rules to priorities packets of data among all the connected devices. It can play a big role when we need to assign most bandwidths to particular devices. 2. Simple Network Management Protocol(SNMP) SNMP is another widely applied protocol which allows network managing and monitoring. It’s a crucial feature to monitor the network performance without touching the switch. All the potential problems can be flagged and fixed through a management page. When problems occur, the technical team is able to identify easily and solve the problems more efficiently. 3. Virtual local Area Networks(VLAN) VLAN is also a mostly needed configuration function which allows network administrators to group devices together without extra wiring or other changes to the current network infrastructure. VLAN can be configured under different rules to establish communication rules between all the Ethernet ports. Unlike the unmanaged types, all the Ethernet ports have access to the same data transmission and network traffic, with VLAN function, we can easily protect certain LAN ports from communicating with other ports. All the ports can be isolated by different rules, changes are also easy to be arranged. 4. Redundancy The function of redundancy is to duplicate data if any part fails in the network. With this function, the duplicated data will be a safe back up for follow-up recovery. 5. Port Mirroring Port Mirroring is a feature designed to help diagnose potential network faultily. A Managed POE switch allows customers to send copies of traffic to an individual port on the same switch to do the analysis. The network analyzer enables the disgnose and fix the possible problems without uninstalling the devices from the network. H3B Managed POE Switches: Designed to meet your network needs.

Blank copper pcb board is a printed circuit board, also called printed wiring board, which is an important electronic component, the support of the electron component, and the supplier of the electrical connection for the electron component. Since it is made with electron printing, it is called a "printed" circuit board. As the electronic instruments become more and more complicated, the parts they need become much more accordingly, and the circuit and the parts on the board become denser. The blank PCB (without parts on) is often called the "Printed Wiring Board (PWB)". The substrate of the board is made of materials with attribution of insulation, thermal insulation, and inflexibility. The tiny wires can be seen on the surface is the copper foil which had been covered the whole board, but partially etched, then the remaining part formed the tiny netted wires. And these wires are called conductor pattern or electric wiring, which is used for offering the electrical connection for parts on PCB. Generally, the color of the PCB is green or brown, which is the color of the solder mask. It is the protective layer of insulation to protect the copper foil and preventing the parts from being soldered onto the incorrect positions. Silkscreen will be printed on the solder mask where words and marks (mostly white) will be printed in order to highlight each position of the parts. The silkscreen is also called a legend.

PTH Hole in PCB / PTH PCB There are three common types of drilled holes in the printed circuit board: PCB through hole plating , blind via hole, and buried via hole. Therefore, PCBs are classified according to drilling methods and can be divided into plated through-hole PCB, blind via hole PCB, and Buried via hole PCB. PTH is the most common drilling method, and it is common in various types of PCBs. SPEEDAPCB has been focusing on the production of various PTH (plated through hole PCB-PTH PCB), buried via hole PCB and blind via hole PCB. HAVE A QUESTION OR REQUEST? Click below, we’ll be happy to assist. Drilling Method of Plated Through Hole PCB Plated Through Hole, the copper foil lines between conductive patterns in different layers of the circuit board are connected or connected with this type of hole, but the copper legs of the component lead or other reinforced materials cannot be inserted. The PCB is formed by the accumulation of many copper foil layers. The copper foil layers cannot communicate with each other because each layer of copper foil is covered with an insulating layer, so they need to rely on via for signal connection. The through hole of the circuit board must pass through the plug hole to meet the customer's needs. In changing the traditional aluminum sheet plugging process, the solder mask and plug hole on the circuit board surface are completed with a white net to make its production more stable and the quality more reliable , More perfect to use. The vias help the circuits to be connected to each other. With the rapid development of the electronics industry, higher requirements are also placed on the PCB manufacturing process and surface mount technology. The plugging process for vias came into being, and at the same time, it must meet the following requirements: 1. Only copper is required in the hole, solder plug can be plugged or not; 2. There must be tin-lead in the hole, with a certain thickness requirement (4um), to avoid solder mask ink entering the hole, causing tin beads to be hidden in the hole; 3. The through hole must have a solder resist ink plug hole, opaque, no tin rings and beads, and must be flat. Through-hole boards are common in all fields and are one of the most common PCBs. Generally, the mobile phone board or PDA board has a board that uses a combination of blind and buried holes. The buried hole can reduce the probability of signal interference, maintain the continuity of the transmission line's characteristic impedance, and save routing space. Circuit board design. This type of board requires high technical content and accurate accuracy, so relatively speaking, the requirements for factory equipment are much higher than ordinary multilayer boards, and the cost of such circuit boards will be much higher than ordinary Shelf should be high.
