45 steel is a medium carbon structural steel with good cold and hot working properties, good mechanical properties, low price and wide sources, so it is widely used. Its biggest weakness is that its hardenability is low, and the workpiece with large section size and high requirement is not suitable for use. The quenching temperature of 45 steel is A3+ (30~50) C, and in practice, the upper limit is generally taken. The high quenching temperature can accelerate the heating speed of the workpiece, reduce the surface oxidation, and improve the work efficiency. In order to homogenization the austenite of the workpiece, enough insulation time is needed. If the actual furnace load is large, it is necessary to extend the holding time appropriately.High Temperature Lab Vacuum Heat Treatment Furnace For Sintering Powder

Because of the intermeshing of the screw and the close cooperation between the screw and the inner wall of the liner, the suction and discharge ports of the pump will be separated into one or more sealing spaces. As the screw rotates and engages, these sealing spaces are formed continuously at the suction end of the pump. The liquid in the suction chamber is sealed in it, and the liquid in the suction chamber is continuously pushed from the suction chamber along the screw axis to the discharge end. The liquid enclosed in each space is continuously discharged, just like a nut pushing forward when the screw rotates. The number of screw rings is regarded as liquid. When the screw rotates, the screw thread is equivalent to the liquid in the screw pump. This is the basic working principle of the screw pump.small electric arc furnace for many fields

The speed of the screw pump, the effect of the running speed on the screw pump, the impact of the speed of the screw pump on the performance, although the screw pump can theoretically run as fast as other types of pumps (1800r/min, but they rarely reach this speed. The first reason is the imbalance caused by the geometry of the “chapter” rotor (for example, in addition to the needs of the flood control industry, we have developed a submersible pump product that is light and has a large flow rate as a flood control pump, according to Newton's law: It means that the faster the pump rotates, the greater the imbalance. For the detailed information, you can view the large-flow portable submersible pump. Fog Machine Electric Spray Pump

In the foundation pit, the foundation pit is excavated for about 40 ~ 50m and 10m wide. Depending on the thickness of the ore body, the foundation pit can be excavated to the floor of the deposit at one time or in segments, and the depth of the pulp pool in the pit is generally about 1.5m.
The trench trench method is used to dig trenches, and ore trench channels are set up in the trench to transport the placer by gravity. If it crosses the concave ground, it can cooperate with the self flowing inverted siphon, without power, and is economic and reliable.
Adit hole development method is used to dig adit and chute to ore body. A slip pipe is installed in the shaft, and the adit is flush with a mining ditch. This method is applicable to low-pit dispersed ore blocks in Karst hillside areas. In order to save power, self-flow transportation should be adopted as far as possible to avoid sand pump lifting. The length of adit used at present is 2.6Km. The chute is divided into two types: vertical and inclined. The well is supported by dense pillars. The diameter of the slip pipe is usually 350mm, and the slurry is sent through the pipe to the trench in the adit. There are two ways to arrange the gully: one is to build on the floor of the adit, which is suitable for mines with short service life; the other is to excavate under the floor of the adit. Buffer tanks are installed at the connection between the pipeline and the flushing ditch to reduce the impact force and prevent the slurry from splashing when it flows out of the pipe. A sieve should be provided at the upper entrance of the pipeline to prevent blockage of pipes by large lumps and mud masses.

In 1979, Germany first changed the traditional 50t ultra-high power electric arc furnace to central bottom tapping, and then changed it to more perfect eccentric bottom tapping. The biggest characteristic of eccentric furnace bottom tapping is to move the tapping hole outside the furnace shell for easy maintenance and repair. Eccentric bottom tapping matches ultra-high power, which has been developed and popularized rapidly in developed countries. Especially for large-scale slag-free electric arc furnace, its advantages are obvious, mainly as follows:
(1) more than 98% slag can be retained in the molten pool.
(2) the consumption of refractories can be reduced by about 25%.
(3) when molten steel is tapping, the temperature of molten steel will generally drop by 25 degrees Celsius.
(4) the tapping time is short, and the tapping time of 60t EAF is only about 80s.
(5) the electricity consumption per ton of steel can decrease by 20kW. H.
(6) the consumption of steel electrodes per ton can be reduced by about 0.5kg.Cemented Carbide Forge Sintering Furnace

After some investigations, 90% of people think that stainless steel is not rusting steel. If you use a good stainless steel such as 304 and 316 stainless steel raw materials to make stainless steel one-meter railings, it will definitely not rust. However, "steel that does not easily rust" is not "steel that does not rust."

The principle of stainless steel is that the stainless steel's rust and corrosion resistance is due to the formation of a chromium-rich oxide film on the surface. This stainless steel and corrosion resistance are relative. The test surface, steel in a weak medium such as atmosphere and water, and nitric acid. In the oxidizing medium, the corrosion resistance increases with the increase of the chromium content in the steel. When the surface material reaches a relative percentage, the corrosion resistance of the steel is abrupt, that is, from rust to rust, it seems that stainless steel It does not necessarily rust, but it is much lower than other steels in the same environment. So the above information can tell you that the stainless steel railings are not rusting.

The customer thinks that the 304 stainless steel railing seat will be rusted at a higher price. Is there no way to deal with it? Siyu Metal now tells you that in fact, you don't have to worry, 201, 304 stainless steel railings will rust, but everyone also sees that its rust resistance is much better than other iron and other steel, it is not without human law. Stop the rust on its surface. In order to ensure that the surface of the stainless steel railing is permanently glazed, we recommend that the surface of the column and the cover of the stainless steel one-meter railing be cleaned frequently with a clean alcohol scrub. If there is a serious rust point, use a scouring pad to gently polish it, pour a little 99 wax on the sponge without water, and then wipe the whole tube with a sponge.

In 1982, the world's first DC electric arc furnace was manufactured in Germany. The central graphite electrode was used as the cathode access circuit. The bottom electrode was an anode, consisting of two horizontal metals. The metal plate was equipped with air-conducting cooling sheets. Many contacts were attached to the metal plate, and magnesia was filled between the contacts. The current flows into the contact pin through the horizontal metal plate at the bottom of the furnace and then passes into the molten pool. The operation of DC electric arc furnace is not different from that of AC electric arc furnace, but in order to keep good contact between charge and bottom electrode, some molten steel should be retained during tapping. To replace the steel, the molten steel in the furnace must be removed.1200C Laboratory Electrical Inert Gas Quartz Tube Vacuum Pyrolysis Furnace

1. Hot rolling (extrusion seamless steel pipe): round billet → heating → perforation → three-roll cross-rolling, continuous rolling or extrusion → pipe removal → sizing (or reducing diameter) → cooling → straightening → hydraulic test (or flaw detection) → mark → the raw material for the seamless tube is the round tube blank. The round tube embryo is cut into a blank with a length of about 1 meter by a cutting machine, and sent to the furnace for heating through a conveyor belt.

The billet is fed into a furnace and heated to a temperature of approximately 1200 degrees Celsius. The fuel is hydrogen or acetylene. Furnace temperature control is a key issue. After the round billet is released, it is subjected to a through-hole punching machine. The more common perforating machine is a conical roller punching machine. This perforating machine has high production efficiency, good product quality, large diameter of perforation and can wear a variety of steel types. After perforation, the round billet is successively rolled, rolled or extruded by three rolls. After extrusion, the tube should be sizing. The sizing machine is rotated at a high speed by a conical drill bit into a steel core to form a steel pipe.

The inner diameter of the steel pipe is determined by the outer diameter of the sizing machine drill bit. After the steel pipe has been sized, it enters the cooling tower and is cooled by water spray. After the steel pipe is cooled, it is straightened. After the steel pipe is straightened, it is sent to a metal flaw detector (or water pressure test) by a conveyor belt for internal flaw detection. If there are cracks inside the steel pipe, bubbles and other problems will be detected.
