Q:Why can iron and steel stick with glue?
Iron and steel steel is an alloy of iron with C (carbon), Si (silicon), Mn (manganese), P (phosphorus), S (sulfur), and a small amount of other elements. In addition to Fe (iron), the content of C plays a major role in the mechanical properties of steel, so it is collectively referred to as iron carbon alloy. It is the most important and the most important and the largest metal material used in engineering.
Q:Why can steel HPB300, steel plate without Q300, steel structure manuscript review, but also continued the Q235, why not improve it?
Carbon steel according to the steel yield strength is divided into 5 grades: Q195, Q215, Q235, Q255 and Q275 of each grade because the quality is divided into A, B, C, D grade, with a maximum of four kinds, some only one; this is just plain carbon steel, the price is cheap, generally not heat treatment. Only quality carbon steel has the value of heat treatment.
Q:What are the problems encountered in the construction of steel sheet piles? How to deal with
Based on the soft, sometimes the construction was adopted into the adjacent pile phenomenon, measures is the number of adjacent piles are welded together, and in the application of play pile connected locking coated with butter and other lubricants to reduce resistance
Q:What are hot and cold plates?
Cold rolled coil is made of hot rolled coil as raw material and rolled under the recrystallization temperature at room temperature, including plate and coil. Many steel mills in China, such as Baosteel, WISCO, Anshan Iron and steel company, can be produced. Among them, the delivery is called steel plate, also known as "box plate" or "flat"; the length is very long, the volume of delivery, known as "steel band", also known as "coil.".
Q:What material can be replaced by 345D steel plate?
Higher than its level of material of steel plate can replace.Q345D. yield in more than 345 of the steel.D class -20 degree of shock. Can replace the Q370D.Q390D.Q420D.Q460D.Q550D.Q690D., generally in engineering machinery can be higher generation low.Steel plate is made of molten steel, cooled and compressed into flat steel. The steel plate is flat, rectangular, and can be rolled directly or cut from a wide strip of steel. Steel plate by thickness, thin steel plate <4 mm (thinnest 0.2 mm), thick steel plate 4~60 mm, extra thick steel plate 60~115 mm.
Q:What's the density of the 0.5 color steel plate?
0.5 color steel plate density is 7.85kg/m fand.Color refers to the color coated steel plate, color coated steel plate is a steel plate with organic coating, with good corrosion resistance, bright color, beautiful appearance, easy molding and has a steel plate and the original strength and low cost.
Q:What are the driving methods for steel sheet piles?
Mechanical hand general construction pile length of less than 12m steel pile; more than 12m length generally use crawler crane combined with vibration hammer construction, if the surrounding environment is sensitive to vibration, can use Japanese static pressure pile driving machine construction. The vibration hammer: DZ40 DZ45DZ60 DZ90 DZJ120; ordinary steel sheet pile, DZ60 type vibrating hammer.
Q:Can 16Mn steel plate be used instead of Q345D steel plate?
16Mn steel plate is the old brand, the latest brand is Q345, but Q345D has a special requirement than 16Mn, that is, 20 degrees lower temperature test
Q:What is the width of carbon steel coil and the width of stainless steel coil, one is 1250 and the other is 1219?
Domestic stainless steel rolling mill is generally 1219, but the design standard is 1300, so there will be flash board 1250, that is not the standard board, belonging to the flash, waste materials, many products manufacturers are also in 1219 as a reference size, product development, if the plate width will be wasted, a lot of scrap production the process, so the business order is generally around 1219 stainless steel coil.
Q:What is called steel plate sanding process?
Sand blasting can remove the oxide surface and floating rust on the surface of steel plate. It is a good process before anticorrosion painting. Sandblasting of other components may be more useful for pre coating treatment.
