中厚板及应用1、什么是中厚板中厚板是指厚度4.5-25.0mm的钢板分

Medium and heavy plates and their applications <br>1. What is medium and heavy <br>plates ? Medium and heavy plates refer to steel plates with a thickness of 4.5-25.0mm, including ordinary carbon plates, superior carbon plates, low alloy plates, ship plates, bridge plates, boiler plates, container plates, etc., Thickness above 4.0mm is medium-thickness plate, of which 4-20mm is medium-thickness plate, 20-60mm is thickness plate, and 60mm or more is extra-thickness plate. <br>The raw materials of medium and heavy plates are mainly steel billets, and the downstream applications are mainly: manufacturing, shipbuilding, petroleum and natural stone pipelines, transportation projects, major public buildings, etc., of which the use of machinery accounts for the main position, and ordinary plates are the main ones. Other high-strength plates and varieties of steel are mainly used in shipbuilding and bridge fields, and have an important position in the plate industry chain. <br>2. Application of medium and <br>heavy plates Steel plates for pressure vessels: mainly used to manufacture pressure vessels and other similar equipment for petroleum and chemical gas separation and gas storage and transportation. The general working pressure is from atmospheric pressure to 320kg/cm2 or even 630kg/cm2, temperature Working in the range of -20-450°C, the container steel plate must have a certain strength and good plasticity and toughness, but also have good cold bending and welding properties, such as: Q245R, Q345R, 14Cr1MoR, 15CrMoR, etc.

Medium thick plate and application.<br>1, what is a medium-thick plate.<br>Medium-thick plate refers to the thickness of 4.5-25.0mm steel plate sub-carbon plate, excellent carbon plate, low alloy plate, ship board, bridge board, boiler plate, container plate, etc. , thickness of more than 4.0mm for medium-thick plate, of which 4-20mm for medium plate, 20-60mm for thick plate, more than 60mm for special thick plate.<br>The raw materials of medium-thick plate are mainly steel billets, and the downstream applications are mainly: manufacturing, shipbuilding, petroleum and natural stone pipelines, transportation engineering, major public buildings, etc., where mechanical use occupies the main position, mainly in general plate, other high-strength plates and varieties of steel are mainly used in shipbuilding and bridge fields, in the plate industry chain has an important position.<br>2, the application of medium-thick plate.<br>Steel plate for pressure vessels: mainly used in the manufacture of oil, chemical gas separation and gas storage and transportation of pressure vessels and other similar equipment, general operating pressure at normal pressure to 320 kg/cm2 or even to 630 kg/cm2, temperature at -20-450 degrees C In addition to having a certain strength and good plasticity and toughness, container steel plates are required to have better cold bending and welding properties, such as Q245R, Q345R, 14Cr1MoR, 15CrMoR, etc.

Plate and its application<br>1. What is plate<br>Medium plate refers to the steel plate with thickness of 4.5-25.0 mm, including ordinary carbon plate, excellent carbon plate, low alloy plate, ship plate, bridge plate, boiler plate, vessel plate, etc. the plate with thickness above 4.0 mm is medium plate, in which 4-20 mm is medium plate, 20-60 mm is thick plate, and over 60 mm is extra thick plate.<br>The raw materials of medium and heavy plate are mainly steel billet, and the downstream applications are mainly manufacturing industry, shipbuilding industry, oil and natural stone pipeline, transportation engineering, major public buildings, etc. among them, the use of machinery is the main part, and the common plate is the main one. Other high-strength plates and varieties of steel are mainly used in shipbuilding and Bridge fields, which play an important role in the plate industry chain.<br>2. Application of medium and heavy plate<br>Steel plate for pressure vessel: it is mainly used to manufacture pressure vessels and other similar equipment for gas separation and gas storage and transportation in petroleum and chemical industry. Generally, the working pressure is from normal pressure to 320kg / cm2 or even 630kg / cm2, and the temperature is within - 20-450 ° C. besides certain strength, good plasticity and toughness, the steel plate for vessels must also have good cold bending and welding properties, such as Q245R Q345R, 14Cr1MoR, 15CrMoR, etc.<br>
