              熱軋是相對于冷軋而言的,冷軋是在再結晶溫度以下進行的軋制,而熱軋就是在再結晶溫度以上進行的軋制。工藝流程:原料(冷軋鋼卷)→開卷→剪切頭尾→焊接→堿液噴洗→堿液涮洗→電解脫脂→水涮洗→一級水洗→二級水洗→熱風干燥→入口活套→還原退火→熱浸鍍鋅→鋅層控制→冷卻→光整→拉伸彎曲矯直→鈍化→烘干→出口活套→靜電涂油→出口剪切→卷取→卸卷→鋼卷稱重→包裝→入庫。

              Hot rolling is relative to cold rolling, cold rolling is below the recrystallization temperature of rolling, and hot rolling is above the recrystallization temperature of rolling. Process flow: raw material (cold rolled steel coil) uncoiling shear end welding 8594 alkaline spray washing alkaline washing electrodegreasing 8594; water washing first water washing 8594; second water washing hot air dry 8594 inleloop 85Reducannealing 8594 hot dip galvanizing 85zinzinc layer control 8594 cooling 8594 \8594 8594 8594 electrodegreasing 8594 \\\\\\\\\\\Drying to Export It is composed of electrostatic oiling, export cutting, coiling, unloading, volume weighing, packaging and warehousing.

              你好,鋼管的熱鍍鋅采用齒盤全浸式半自動鍍鋅方式撥入、壓下、螺旋、拔出、提升的機械原理,完成熱鍍鋅過程。

              Hello, the hot-dip galvanizing of steel pipes adopts the mechanical principle of dialing in, pressing down, screw, pulling out and lifting by the full-dip semi-automatic galvanizing method of tooth disc to complete the hot-dip galvanizing process.

              1、工藝參數控制:鋅液溫度應控制在440-460℃之間;浸鋅時間應控制在30-60秒之間;加鋁量(鋅液面含鋁量0.01-0.02%)

              1. Process parameter control: zinc liquid temperature should be controlled between 440-460%, zinc dipping time should be controlled between 30-60 seconds, aluminum content (zinc liquid surface aluminum content 0.01-0.02%).

              2、鋅錠使用應為國標Zn0-3鋅錠。

              2, the use of zinc ingots should be the national standard Zn0-3 zinc ingots.

              3、要經常維護控制好拔入壓下螺旋、拔出提升裝置的可靠性能,加強氣缸的潤滑,調整好鍍鋅管分配器的高度、角度,將設備調整到最佳狀態。

              3. Maintain and control the reliability of pull-in screw and pull-out lifting device, strengthen the lubrication of cylinder, adjust the height and angle of galvanized pipe distributor, and adjust the equipment to the best state.

              4、接近開關的擺放位置要準確無誤;熱電偶線和表要統一型號使用,否則,溫度誤差大,熱電偶的保護套管,要經常檢查更換。

              4. The position of the proximity switch should be accurate; the thermocouple wires and watches should be used in a unified model; otherwise, the temperature error is large, and the protective sleeve of the thermocouple should be checked and replaced frequently.

              5、操作臺操作人員要根據爐前設備運行情況及手勢指揮,手動調整速度防止卡管現象。

              5. Operators of the operating table should adjust the speed manually to prevent pipe jamming according to the operation of the equipment before the furnace and the gesture command.

              6、爐前工使用工具要先預熱再使用,以防止濺鋅傷人;經常檢查有無鋼管掉入鍋內,如有要及時清出;要及時調整設備別卡管,以保障設備的安全。

              6. The tools used in front of the furnace should be preheated before being used to prevent people from being injured by zinc splashing; the steel pipes should be cleared if they fall into the pot; and the equipment should be adjusted in time to ensure the safety of the equipment.

              熱軋無縫鋼管工藝流程是什么?推薦回答:①熱軋無縫鋼管主要生產工序(△主要檢驗工序):

              What is the technological process of hot rolled seamless steel pipe? Recommended answer: (1) main production process of hot rolled seamless steel pipe (main inspection procedure):

              管坯準備及檢查△→管坯加熱→穿孔→軋管→鋼管再加熱→定(減)徑→熱處理△→成品管矯直→精整→檢驗△(無損、理化、臺檢)→入庫

              Preparing and checking of tube blank heating of tube blank piercing rolling reheating of tube sizing heat treatment straightening finishing checking storage

              ②冷軋(拔)無縫鋼管主要生產工序:

              (II) main production processes of cold rolled (drawn) seamless steel tubes:

              坯料準備→酸洗潤滑→冷軋(拔)→熱處理→矯直→精整→檢驗

              Billet preparation, pickling, lubrication, cold rolling (drawing), heat treatment, straightening, finishing, and testing.

              熱軋(擠壓無縫鋼管):圓管坯→加熱→穿孔→三輥斜軋、連軋或擠壓→脫管→定徑(或減徑)→冷卻→矯直→水壓試驗(或探傷)→標記→入庫軋制冷拔無縫鋼管的原料是圓管坯,圓管胚要經過切割機的切割加工成長度約為1米的坯料,并經傳送帶送到熔爐內加熱。

              Hot-rolled (extruded seamless steel pipe): tube blank heating perforation three-roll cross-rolling, continuous rolling or extrusion stripping sizing (or reducing diameter) cooling straightening hydrostatic test (or flaw detection) labeling storage of seamless tube raw material is round tube blank, tube embryo to be cut through the cutting machine processing growth of about 1 meter, and The conveyor belt is sent to the furnace for heating.

              鋼坯被送入熔爐內加熱,溫度大約為1200攝氏度。

              The billet is heated into a furnace and the temperature is about 1200 degrees Celsius.

              燃料為氫氣或乙炔。

              The fuel is hydrogen or acetylene.

              爐內溫度控制是關鍵性的問題.圓管坯出爐后要經過壓力穿孔機進行穿空。

              The temperature control in the furnace is a key problem. The round tube billets need to pass through the pressure perforator after they are put out.

              一般較常見的穿孔機是錐形輥穿孔機,這種穿孔機生產效率高,產品質量好,穿孔擴徑量大,可穿多種鋼種。

              The common piercer is conical roller piercer. This kind of piercer has high production efficiency, good product quality, large piercing enlargement and can pierce many kinds of steel.

              穿孔后,圓管坯就先后被三輥斜軋、連軋或擠壓。

              After piercing, the round billet is successively rolled, rolled or extruded by three rolls.

              擠壓后要脫管定徑。

              After extrusion, the diameter must be removed.

              定徑機通過錐形鉆頭高速旋轉入鋼胚打孔,形成鋼管。

              The sizing machine punched through the tapered bit into the steel embryo to form a steel pipe.

              鋼管內徑由定徑機鉆頭的外徑長度來確定。

              The inner diameter of the steel pipe is determined by the length of the diameter of the drill bit.

              鋼管經定徑后,進入冷卻塔中,通過噴水冷卻,鋼管經冷卻后,就要被矯直。

              After sizing, the steel pipe enters the cooling tower and is cooled by spraying water. After cooling, the steel pipe will be straightened.

              鋼管經矯直后由傳送帶送至金屬探傷機(或水壓實驗)進行內部探傷。

              After being straightened, the steel pipe is sent to the metal flaw detector (or water pressure test) through the conveyor belt for internal detection.

              若鋼管內部有裂紋,氣泡等問題,將被探測出。

              If there are cracks inside the steel pipe, bubbles and other problems will be detected.

              鋼管質檢后還要通過嚴格的手工挑選。

              After the quality inspection, the steel pipe should be selected by strict manual selection.

              鋼管質檢后,用油漆噴上編號、規格、生產批號等。

              After the quality inspection of the steel pipe, paint numbers, specifications, production batch numbers and so on.

              并由吊車吊入倉庫中。

              The crane is hoisted into the warehouse.

              熱縮套管工藝流程是怎樣的?推薦回答:生產時把熱縮管加熱到高彈態,施加載荷使其擴張,在保持擴張的情況下快速冷卻,使其進入玻璃態,這種狀態就固定住了。

              What is the technological process of the heat shrinkable sleeve? Recommended Answer: In production, the heat pipe is heated to a high elastic state, the load is applied to make it expand, while maintaining the expansion of the rapid cooling, so that it enters the glass state, this state is fixed.

              在使用時一加熱,它就會變回高彈態,但這時載荷沒有了,它就要回縮。

              When heated, it will return to high elastic state, but when the load is gone, it will shrink back.

              簡單來說就是造粒-擠出-輻射交聯-擴張-包裝-完畢

              In short, granulating - extrusion - radiation crosslinking - expansion - Packaging - finish.

              熱縮母排套管和熱縮管一樣的,是以熱塑性聚烯烴為基材,添加不含毒性物質的阻燃劑和助劑合成為復合高分子材料,擠出成管狀、經γ射線輻照或高能電子束轟擊后,線型分子部分鏈段產生交聯,成為具有“形狀記憶”的“熱固性”材料,加熱并將直徑擴張直原來的數倍后冷卻定型。

              The thermoplastic polyolefin (TPO) is used as the base material, and flame retardants and additives without toxic substances are added to form a composite polymer material. After extrusion, some segments of the linear molecule are crosslinked to form a "shape memory" after being irradiated by gamma rays or bombarded by high energy electron beams. "Solid" material, heating and expanding the diameter several times after the original cooling stereotypes.
