Q:The minus sign in front of what 40 galvanized flat steel
In front of a small cross is not a minus sign, but on behalf of the flat symbol. For example, the meaning of "-40*4" galvanized flat steel is: 40 is the width of the section steel, 4 is the thickness of the steel, and the unit is mm.
Q:Are there any differences between flat iron and flat steel?
There are many kinds of iron ore, magnetite, hematite, corresponding to the main components of the ore should all know, or in a similar "write reaction equation" with the topic of carbon monoxide reduction of magnetite occurs, will be at a loss what to do. Next should mainly reflect the principle on iron smelting to understand the reducing agent for iron reduction, must pay attention to the test of the formulation of the phenomenon - "red brown powder into black" (which is often the examination content). From here, the principle of blast furnace ironmaking is approximately the same. For some knowledge in actual production, we should understand the basic structure of the blast furnace five furnace two, three import and export ", and each part of the chemical reaction, the slag formation reaction, the need to pay attention to is: the composition of blast furnace gas is a mixture of gases such as carbon monoxide, carbon dioxide and nitrogen, after purification to it is a gas discharge, good fuel.
Q:What is the weight calculation formula for galvanized flat steel and galvanized steel angles?
That is volume * density = weight.For example: L50*5 angle, general case, hand count is (0.05*2-0.005) *0.005*7850=3.729kg/m; 6m is 3.729*6=22.37kg [formula is W= (both long - and angle angle thickness) * angle thickness *7850* meters, of which 7850 were iron density value after conversion unit after multiple values, namely 7850kg/m3. The length and thickness and the number of meters into units are in meters, the weight of the unit is kg W.
Q:How can copper cables and flat steel be welded together?
The copper cable is pressed into the nose. It is punched through the steel and screwed,The national standard atlas is connected with a total equipotential terminal box.
Q:What do the numbers in the steel HN346*174*6*9 refer to?
Small steel: small steel, middle, round, square, flat steel processing and use, similar to large steel, small diameter round steel is often used as building steel.
Q:Earthing flat steel, width, overlap face, bolt, big country net
There is no requirement for the width of the ground steel, the width of the joint surface and the bolt. As long as you lap the joint, the corresponding screw can also ensure the electrical connection and the mechanical strength.
Q:Construction of lightning protection ground galvanized flat steel approach, need to retest test? What's the test?
Forged flat steel is a forged strip of steel with a rectangular cross section. Forging injustice can get certain shape and size and forgings, casting microstructure of the steel is remarkably improved, increase the density of steel; can change the distribution of the fiber structure, clear anisotropy, improve the mechanical properties of the metal, so that the strength and toughness of steel are improved; and it can be used to process the plastic lower high Shuogang and high alloy steel. Forged flat steel is mainly made of high quality alloy steel, mainly used as springs, tools and important mechanical parts.
Q:Can roof strip be replaced with steel pipe instead of flat steel and round steel? Are there any examples of practical use?
Other examples are not used, mainly because the price of steel pipe is more expensive than flat steel and round steel
Q:Connect the equipotential terminal box to the ground flat iron. Can I use plain flat steel?
Specification requirement is 25*4 or 40*4 hot galvanized flat steel, said the family specification is also very reasonable, even galvanized flat steel, long time buried in the soil or on the floor, the wall will be laying, easy to rust, if we use the normal flat iron, not to mention that, certainly rust, but the speed is much faster than galvanized flat steel!
Q:The technological process of flat steel
The production process can be summarized as: pre leveling, finishing, straightening and leveling. Flat /a/b width 12-300mm, thickness 4-60mm, cross section is rectangular and with pure edge of steel. Flat steel can be finished steel, or can be used as the blank of welded pipe and thin slab for laminated sheet rolling. Main application: flat steel is used as a material, used for making iron, tools and machinery parts, and used as frame structures and escalators for buildings. Flat steel is divided into two kinds according to its shape: flat spring, flat steel and single side double slot spring flat steel. Hot rolled spring flat steel is mainly used in the manufacture of automobiles, tractors, railway transportation and other mechanical leaf springs.
